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

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.

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.
