Failures of the mower push-pull switch:
Alamo has recently received reports of failures of the referenced switch. The failures
modes are:
(a) Knob pulls off rod.
(b) Rod and Knob pulls out of switch body.
Test performed on numerous switches indicates that the (b) failures are due to excessive
force being applied to the knob when shutting off the mower. Specifically, the knobs are usually
roughly slapped to turn the mower off. After internal parts of the switch are damaged, the rod can
then be pulled out easily. The (a) failures are due to the knobs not being securely tightened.
To prevent these failures from occurring, or to replace a damaged switch, use the following
procedure to adjust the travel of the switch. (See attached diagram).
1. Install the switch body in the holder and tighten the nut.
2. Screw the Knob on the rod to the bottom of the thread, but do not overtighten. It
will probably be necessary to hold the rod with pliers to get the knob tight, if you do
use caution not to score the rod with the pliers.
3. Measure the distance (if any) between the knob and the nut. Record the
measurement.
4. If a Gap exists between the knob and the nut, remove the knob.
5. Remove the nut and install the same thickness of flat washers that was
measured in step 3. Install and tighten the nut> DO NOT install more washers
than needed to take up the space. Flat Washer Part No. 00023500 or equivalent can
be used.
6. Install the Knob, using Locktite or similar thread locking compound. Thread the
knob on the rod all the way. Test to make sure that when the switch is "Off" (with
rod pushed in) that the knob can not travel further into the switch.

New Piston Pump used on Machete:
A new Pump is being used on all Machete Boom Mowers. The new pump utilizes a solenoid
valve and manifold (New Parts) to control pump swashplate movement instead of the former (Old
Parts) electric solenoid, Spool valve and adjustable linkage. All other parts of the pump remain the
same. The new parts provide for more positive trouble free operation of the pump and do not require
adjustment.
There will be a harness adapter required to connect the new two wire connector to the old
three wire harness. Adapter and instructions are included in replacement parts. When the former (old
part number is ordered, all the new parts will be provided.

New Seal Protector Added to Blade Bar Assembly:
A few machines have experienced operational problems such as failure of the blade bar to rotate
when the mower is engaged or a slight loss of power at the blades. Sometimes it is assumed that the
spindle has seized and the spindle is replaced without investigating further.
The problem is usually found to be that the spindle end cap cover is binding on the spindle
housing, creating sufficient drag on the shaft to result in the symptoms described above. This condition
is a result of material (Vines, Wire, etc.) wrapping around the cover and forcing it to contact and drag
against the spindle housing, causing no damage to internal components of the spindle.
A new seal protector has been designed to aid in preventing material from wrapping around the
seal cover area. While nothing can completely prevent material from getting to the seal cover, the new
seal protector should greatly reduce the probability of spindle seizures due to these causes.
If a machine is operating or is going to operate in an application in which material is likely to wrap
around spindle, the following parts can be ordered and installed. The old seal protector (# 02968868)
which is on the spindle will be removed and discarded. The Old Part No. 02968868 will be ordered but
the new Seal Protector Part No. 02970459 will be shipped with installation instructions. If only the new
Seal protector is ordered the instruction sheet will not be shipped.
Part No. Qty Description
02968868 1 Cover, End Cap (Seal Protector)
The new seal protector will have to be welded to the upper blade bar as shown on the next page
and the old seal protector which is on the spindle will be discarded. Make sure that the Blade bar
retaining bolts are properly torqued when reattaching to spindle and that components are good
condition.

Oil Leaking from new single Acting Hydraulic Cylinders:
There have been numerous cases of the dealers and customers replacing single acting
hydraulic cylinders on new machines due to oil leakage out of the vent plug in the cylinder.
In many of these instances, no defect could be found in the cylinders. Further investigation
has revealed that he manufacture of our cylinders is leaving oil in the cylinders after their testing. The
Oil is left to help protect the interior of the cylinders during storage. When the cylinders are fully
actuated, they are forcing this oil out the vent plug, causing what appears to be a leaking cylinder
through the vent plug. Even the oil is cleaned off the cylinder after testing there is enough oil still inside
the cylinder to bleed out when used.
If you have a New Cylinder that appears to be leaking from the vent plug, The oil should be
cleaned off and unit ran for a few days to a week to determine if the Cylinder is leaking, or if it is the
oil that was left in the cylinder to protect it. It has been found that in some cases it has taken as much
as a week for this to appear that it is not leaking.
If after running and cycling the cylinder during operation and the cylinder continues to leak then
the necessary repair should be performed.
Cylinders that are attracting dust around them is not considered to be leaking. This dust
collecting around them is considered normal.
All Cylinder that are returned as leaking will be pressure tested for leakage to determine the
condition of the Cylinder and its components.

Dead Batteries on New tractors:
There have been several reports recently of dealers receiving machines with dead batteries,
some of which could not be satisfactorily recharged. Please see the attached copy of a tag which
is coming with the new tractors.
The "small electrical discharge" being mentioned amounts to a constant drain on the battery.
If the battery cable (+ Post) is left connected for a long enough time with the tractor inactive, the battery
will become sulfated (permanently damaged) and will not accept a charge. Sulfated batteries are not
warranted through the battery manufacturer.
At present, the only alternative to removing the battery cable would to be install a battery
disconnect switch in the negative cable, which would allow the battery to be easily isolated. These
switches are available at most major tractor dealers. USE CAUTION when installing any thing on
battery cables, disconnect the positive cable before installing disconnect switch and make sure after
switch is installed that it is "OFF" before reconnecting Positive Cable.
ATTENTION ! BATTERY CARE
Your new Tractor has electronics which cause a very small electrical demand on the battery. If the
tractor in not in use for an extended period, disconnect battery to avoid damage by excessive discharge.

There have been some cracks
in the main frame of some machete
mowers
If a crack should develop (See
Figure 1), use the following procedure to
make repairs untill a permanent repair is
developed. NOTE: This repair will aloow
the machine to continue operating while
a long term correction for the problem is
being developed.
1. Grind out old weld (crack) and
weld the crack, Do not use an excessive high repair weld as you will need to
grind repair weld down smooth.

2. Prepare a piece of 1/2" X 6"
HRFB cut to length (See Figure 2). The
bottom should rest against the King
Post frame and the top should be with in
2" of the top of the frame, this will
determine the height of the repair plate
(See Figure 3). Bevel the bottom side of
the plate that is towards the frame to
allow for the old weld. This will be evedent
if you test fit the repair plate.
3. Place the stiffener repair plate
against the vertical memeber of frame
(as shown in figure 3) and tack weld into
position, Make sure repair plate is flat
against the frame.

Interference between Tube Clamps and Main Frame:
It is possible that the boom hydraulic tube clamps may contact the main frame when boom
is raised to its highest position. This condition effects only machines with certain frames. If you have
a machine that has this interference problem use the procedures described in this bulletin to correct
the problem. (See Figure 1).
25"
To prevent interference of the
hydraulic pipe clamps with the
frame move the clamps to this
new 25" distance
Figure 1
If the parts on your unit are damaged, loosen the six bolts that hold the three tubes. Cut the
bracket away from the boom. Relocate the bracket on the boom so it clears the frame. Weld in place
and paint. Tighten the six bolts. Total time to perform this modification will be approximately 1.5 hours
time or less. If parts are required there is a kit that can be installed, the Kit # 02971938.

Tilt Link Arm Stop:
Some Machete models may exhibit interference between the head tilt cylinder and the cutter
motor support plate. This can result in a bent head tilt cylinder rod, a damaged cylinder gland cap, or
a damaged cutter motor housing.
In order to avoid possible damage, a stop should be fabricated and installed which will limit the
head tilt retraction before interference occurs.
A stop made from 1/2" X 2-1/4" HRFB X 6-1/2" long should be welded to head tilt link arm
weldment as shown in figure 1. This will require welding and painting.
To locate the proper angle position of the new stop, carefully retract the head until the cutter
motor support plate and the head tilt cylinder has a clearance of 1". Use caution, do not damage cylinder
when retracting the head. Place the new stop plate in the head tilt link weldment and lay it flat on the
dipper arm. Mark this position, and weld the stop in place as shown in Figure 1. It is important that the
stop is installed so that it flatly contacts the dipper when retracted in order to avoid point loading on the
boom. Extend and retract the cylinder to ensure proper installation.

New Thick Blade Bar & Larger Bolts:
Early October 1996, in order to ensure an extended service life, a new blade bar was introduced
which featured larger blade bar leaf bolts (from 7/8" to 1-1/4") and a thicker bottom leaf. As a result,
longer mounting bolts (from 3-1/2" to 4") are required to ensure adequate thread engagement into the
spindle shaft.
When ordering a replacement blade bar using the original number, the new blade bar design
will automatically be sent. However, the 4 longer mounting bolts may not be included.
Therefore, when ordering a replacement blade bar, ensure that the proper length mounting
bolts (P/N 02964861 which is a 4" Bolt) are also replaced. DO NOT attempt to mount the new style blade
bar using the old shorter bolts. The best way is to always check the replacement bottom leaf thickness
as compared to the bottom leaf that was removed. If the replacement is thicker then the new longer
bolts will be needed. Another way to determine which one you have check the Leaf retaining bolt size.

Lock Valve Installation Instructions:
Instructions for installing a lock valve on the tilt function of an Alamo Industrial Model Machete
Boom product manufactured before May 1, 1997.
The nominal leak down rate for the cutter head tilt section of the electrically controlled positioning
valve is one inch of rod travel in four minutes. If your machine exhibits a leak down rate substantially
greater than this, it typically indicates excessive valve component wear due to contaminated oil in the
tractor. Refer to the Tractor's Operator / Maintenance guide concerning Oil & Filter change intervals to
eliminate contamination possibilities.
If the cutter head tilt cylinder leak down is greater than one inch of rod travel in four minutes and
this is considered excessive, a lock valve may be added to the tilt function of the boom machine. Alamo
Industrial has developed a cure for this and can provide (at a nominal charge) all the parts for a lock out
vale for the tilt function. The Lock valve will only work on the tilt function of the Boom Machine due to the
design of the hydraulic System. The only parts that must be provided by the installer are two, twelve inch
pieces of 18 gauge wire. Each wire needs to have a # 8 ring connector on one end and a wire splice
connector on the other end.
The drawings on the next page shows the details of the parts and their assembly. The Lock Valve
must be installed in the "C-1" port of the cutter head tilt section
The following parts are required to make this modification:
Part No. Qty Description
02972180 1 Straight Hydraulic Adapter (available from Alamo Industrial)

Electrical connection:
Identify the plus (+) lead running to the solenoid for the tilt function. This solenoid is located across
the valve from the fitting you installed. Remove approximately 2 " of the outer plastic covering from the
wires coming from the solenoid. Splice one of the 18 gauge wires you provided into one of the wires.
Connect the other end of that wire to a lug on the solenoid. It makes a difference which wire runs to which
connector. Insulate any exposed wires with electrical tape.

Eleminate Erratic Boom movement:
(which utilize the joystick operated proportional valve system)
Procedures to eliminate erratic boom operation caused by microwave interference from
customer installed two-way radios.
There have been some scattered reports in regards to erratic or unexpected movement of one
or more of the proportionally controlled boom functions of the joystick control system during the
operation of the customer installed two-way radios.
Specifically, the Swing , Lift or Dipper functions may operate at a speed of one foot of movement
every 10 to 20 seconds, depending on the function and direction, when the radio microphone is keyed.
Research and experiments with machines in the field has revealed that this phenomenon is the
reception of the signal transmitted by the radio passing through the variable controls of the boom control
system. Specifically, the wire harness of the control system acts much like a receiving antenna and
receives the radio signal which sends a false signal through harness.
Elimination of the interference may be obtained with the use of at least of three possible options:
1. Remove the radio from the tractor completely.
2. Install a reflecting plate under the Antenna. A reflecting plate is simply a thin, flat piece of metal
which provides the proper amount of impedance to essentialy reflect the signal emanating down from
the antenna and prevent interference with the valve electronics and tractor functions. Since the
installation requires a fairly large (at least 36" square) area, the specially designed reflecting or "ground
plane tape" can be used in place of the metal sheet for easier installation. this tape is available at most
electronics or radio equipment sources.
3. Utilize a ground plane antenna. These specially designed antenna utilize the standard central
radial element and at least two other radials set at 45° angles to the central one. These radials must
be cut to specific lengths depending on the frequency of the system. Only a professional radio installer
or retailer should be consulted in regard to the avaialbility and proper installation of these antenna.
The installation, operation, and resulting effects to the tractor or any attachment due to the
addition of a radio system to any machine is the responsibility of the machine owner and the radio
installer. Only trained, profesional radio installers should be utilized.

Hood to Frame Interference on TS Series Tractors:
On some occasions, it has been reported that the initial mount kit designs involving the
installation of the current A-Boom or Machete Boom mowers to New Holland TS90, 100 or 110 tractors
allowed the main frame cross over / cooling tube to interfere with the movement of the hood. This
interference would not allow the hood to open to provide access to the required maintenance points
of the tractor engine.
To compensate, the hood was required to be completely removed to perform the required
maintenance procedures.
A spacer kit which lifts the frame to provide clearance between the hood and the cross / cooling
tube enough to allow the hood to open to the first position is now available for all of the affected tractors.
The kit components should be installed per the instructions provided in the kit. likewise, all
required hood components such as hinges, shocks & etc. should also be installed

New Oil Filter Kit P/N 02976069:
Detailed investigation of recent valve failures revealed that in the vast majority of the
incidences, the failures are attributable to contamination within the tractor hydraulic systems which
supply pressure to the control valve. Failure normally take the form of one or more inoperative or
poorly operating functions. Repair may involve the replacement of the electronic controller for the
section or, in severe cases, the replacement of the entire valve. Particulate contamination in the form
of small gear metal or brass particles created during break-in and operation and are not removed
during required maintenance of the tractor can enter the valve, this creates leakage due to wear or
clogging of passageways.
In response, an in-line pressure filter and fitting kit (Kit P/N 02976069) has been developed
for installation in the pressure line which delivers oil to the valve. The kit provides all the necessary
fittings, hardware and instructions to facilitate the correct installation.
Installation of the Filter Kit will greatly reduce the
possibility of the occurrence of failures within the Machete
control valve due to particulate contamination. This contamination may result from poor maintenance of the tractor
hydraulic system or other hydraulic system performance
characteristics or problems.

Control Valve Relocation:
The 2001 Machete will reflect a change in the way some of the components are mounted to
the tractor. New Machete units received from the factory, or assembled by dealer after S/N MB2101572 & UP or MB24-01245 & Up will have the control valve in a new location. It will no longer be
mounted on the frame. The Control Valve will be located under the front pump cover in the front of
the tractor. This change was made to better protect the Valve and its components from debris and
other possible damage.
As you can see in figure 1,
the valve is fastened to a plate
that is mounted to the units hydraulic tank. The Pressure Filter
was relocated to a bracket on top
of the tank. Both the Pressure
Filter and the Pump Filter are
accessible and can be changed
with minimal effort. Sepaarate
hose exstension were used to
extend the hose reach to the front
of the tractor. If a hose connection is not easily accessible, then
the valve and mounting plate can
be unfastened an arranged to allow for romm when servicing.

Change in the availability of rebuilt components:
This bulletin has been published to inform you of a change in the availability of rebuilt parts.
In the past, rebuilt components such as pumps and motors were available for use as spare parts.
That will no longer be the case. The major factor in this decision was the lack of cores that are returned
from the customer.
Since Alamo Industrial will no longer offer rebuilt parts an effort will be made to offer customers
a complete parts listing of all components that are needed as service repairs. The most common
service parts are pumps and motors will now be available for order through Alamo Industrial
Customer Service Department. Likewise, a parts breakdown with Alamo Industrial part numbers will
be provided. The Eaton Pumps and Motors, Danfoss Control Valves will be the first components
available with such a parts breakdown.
It is Our intention to provide a better and more reliable service parts system. This transition
will better suit customer, and provide more timely and efficient parts delivery.

In an effort to comply with certain requirements in regard to Tier II Emission Standards, Deere and
Company initiated a change to the crank shaft pulley on many of the new 6020 series tractors. This was
a random change, which did not affect all tractors. In addition, a specific serial number break does not
exist to identify the affected units.
The Tier II pulley can be identified as a 5 spoke design as indicated in the figure above (See Figure 1).
This pulley must be changed to the tapered lock, solid cast pulley as shown to allow adaptation of the
required front pump drive system used to power the Alamo Industrial products. (See Figure 2)
To change the pulley:
Remove the original pulley retaining bolt, shouldered washer and pulley. (See Figure 1) Clean nose of
Crankshaft using LOCKTITE® number 7649 clean and cure primer. Place a light layer 2 mm to 3 mm
(.079 - .118 in.) of LOCKTITE ® brand adhesive number 680 (TY15969) to the leading edge of the
crankshaft nose.
Install the replacement pulley (P/N 02979857) If any paint inside of pulley it needs to be removed. Make
certain to align the pulley with crankshaft, install pulley. (See Pulley Figure 3). Do not hammer on
Vibration Damper (Pulley) it must be handled in a way that avoids impact damage. Make certain that
you installed the Locktite primer and adhesive as described in previous step before you installed the
pulley, this is very important.

Lexan® (Polycarbonate) Shield Upgrade Kit P/N 02980005: (field Install)
Alamo Industrial has designed a Lexan® ( Polycarbonate) Shield that will install on the expanded
metal screen currently used on the Non-Cab models. This is a retro fit kit that is designed to be customer
installed over the expanded metal screen. The Lexan® Sheets will require trimming and the Holes will
have to be drilled in the Lexan
Recommended Tools:
1. Jig Saw or Circular Saw (hand held or table) equipped with plastic cutting blade.
2. Electric Hand Drill, preferably a variable Speed Drill.
3. 3/8" and 1/4" High Speed Steel Drill Bit. (Drill bit should be sharp and in good condition).
4. Measuring Tape or other measuring device.
5. Hand Wrenches for tightening Bolts, do not use air tools to tighten bolts.
6. Straight edge and marker that will write on Lexan.
Lexan Shield Kit Components: (Retro-Fit Kit P/N 02980005 includes:
Part No. Qty Description Part No. Qty Description
02980003 1 Lexan Sheet, Upper 02970004 1 Lexan Sheet, Lower
0461600 20 Bolt, Hex Head 1/4"-20 00024100 20 Flatwasher, Std. 1/4"
02980068 20 Fender Washer, 1/4" 32901C 20 Locknut, 1/4"-20
Protection of Lexan Sheets:
1. Do not remove protective sheet (Paper) from the Lexan® Sheet. This will protect it while you are
working with it. You can drill through this protective sheet as well as cut through it.
2. There are two Lexan® Sheets sent, an upper and a lower. Identify these and mark them to
designate front to rear, inside to outside because once you cut to size to match the existing
Expanded Metal Screen, they cannot be turned around. Cutting these is permanent.
Installation Procedure:
3. Use the measuring tape to get the measurements around your existing Expanded Metal Screen
and write them down, Note there is an Upper and Lower section (See Figure 1).
4. Place the Lexan ® Sheets (Upper and Lower Sheets) on a clean work suface and transfer
your measurements from step 1 to the the Lexan ® Sheets using a Pen or other marker. RE-
CHECK your measurement and when certain they are correct. Cut the sheets out to match
your measurements. Lightly sanding the cut edges will smooth them out and round the outer
edge slightly helping to protect it. Sheets should look like sheets in Figure 2, note the holes will
not be drilled in them yet.

5. Securely clamp the cut Lexan sheets onto the expanded metal screen aligning the outer
edges, this can be done upper or lower sheet first. Using a 3/8" drill bit drill the mounting
holes through the lexan sheet in a pattern as in Figure 2. When drilling the holes in the Lexan
Sheet use the drill to mark the metal frame of the expanded metal screen on all the holes.
When all the holes are drilled into the lexan sheet and marked into the metal frame, remove
the clamps and the lexan sheet.
6. Using a 1/4" Bit, drill the holes into the frame of the expanded metal screen with the Lexan
removed. Note you drilled 3/8" holes in the Lexan and 1/4" holes in the frame work. This is
so that the Lexan will not have a binding fit.
7. Install the Bolts as shown in Figure 3. 1 st. bolt
through frame, 2 nd. install the fender washer, 3
rd. remove the protective cover sheet from the
inner side and install the Lexan sheet, 4 th.
install the Flatwasher, 5 th start the Locknuts
onto the bolts but do not tighten them.
8. Once all the bolts, washers and nut are installed
begin to tighten them. DO NOT over tighten
these Locknuts and put the Lexan sheet in a
bind which will crack it. Tighten the Nuts evenly
and only snug them so the Lexan sheet will not
move. Do this with the upper and lower Sheet.
Then remove the protective cover from the
outside of the sheet.

Turning Arm Pin Update Kit P/N 02974182:
Subject:
Machete Boom Mower Turning Arm Main Pin Retaining Design Update to increase the durability
of the main Pin retaining device.
Service Required:
1. Secure the tractor to facilitate a safe repair, (Engine off, Park brake on, Key Secured & etc..).
You will need a Machete Operators Manual and a Machete Service Manual, these are available
from Alamo Industrial. It is recommended that these manuals are on hand.
2. This will require drilling to install a larger Retaining Bolt and welding to install the Snap Ring
grooved boss (See Figure 1) on the bottom of the Turning Arm Pin, The Old retaining Bolt at the
bottom of the Pin is a 3/8", this will be removed and the hole will need to be drilled out to a 1/2"
to accept the new larger bolt.
3. Make sure that the Boom is out stretched and the head is setting flat on the Floor (Ground). Make
certain that all hydraulic pressure is relieved from the system, this will need to be done manually
at the valve (See Machete Service Manual for this procedure).
4. Support Boom with a hoist as shown in the operators manual and/or service manual before
beginning work on retaining pin.
5. From the under side use a 1/2" thick steel plate and a hydraulic Jack up under turning arm pin
to prevent the pin from falling out when the retaining bolt is removed. Remove the 3/8" retaining
bolt and drill the hole out to a 1/2" hole so you can install the 1/2" Retaining Bolt (See Figure 3)
6. With the new 1/2" retaining bolt installed (do not remove or lower Jack without retaining Bolt
installed) lower the supporting hydraulic Jack and 1/2" steel plate but do not remove it. (See
Figure 3).
7. Install the new Grooved Snap Ring Boss up under the existing Boss that is welded to the turning
arm. Making certain that the OD of new boss is aligned with the OD of the old one, if it is not
aligned the ID of the boss's will not be aligned and Pin cannot pass through it. Using the 1/2" steel
plate and the hydraulic jack, raise jack till there is enough pressure on new boss to hold it
straight and aligned with the existing one. Do Not apply so much pressure that you distort the
new boss. (See Figure 4)
8. Weld the new Snap Ring Grooved Boss to the existing boss. Lower the Plate and Hydraulic Jack
to remove them. Install the New Snap Ring into the groove of the new boss. The purpose of
this snap ring is to keep the pivot pin from dropping out the bottom if the retaining bolt breaks
or comes out.

Port Plug Update:
Subject:
On Machete and Brahma pumps utilizing the
new design Servo Solenoid Valve assembly, An incorrect port plug was installed in the port next to the solenoid
Valve. This incorrect port plug does not allow oil trapped
on the back side of the servo piston to escape to tank,
resulting in incomplete shifting of the servo piston and
thus incomplete stroke of the pump, causing a noticeable decrease in blade speed and performance. Pumps
that need updating can be externally identified by the wire
exit direction on the solenoid coil, a rectangular wire
connection point on the solenoid coil, and a raised button
on the port plug as shown in figure 1.
Once the plug is removed from the manifold, the
incorrect plug can be identified by the secondary sealing
surface and extended length as shown in figure 2.
Service Instructions:
Secure the tractor to facilitate safe repair. Thoroughly clean the top of the pump and around the port plug
and solenoid valve to prevent contamination from be
introduced to the hydraulic system. Remove the port
plug as shown in figure 1 and replace with new port plug
(P/N 02983170) as shown in figure 2. Run and test
mower for operation and hydraulic leaks.
