Parts Book Error - Manual Dated Jan. 1993:
The HYDRO 15 Flex Wing mower is hydraulically - driven and hydraulically positioned machine. As
the operator, you have the most control as to how the machine operates. The operation and
performance of the machine is affected by the adjustment of the machine. Lets look at the many factures
affecting the operation of the Hydro 15.
1. The Tractor Draw Bar should be adjusted to a length of 14", measured from the end of the 540
RPM PTO Shaft of tractor to the center of the tongue hitch pin.
2. The Bolt and Locknut that are installed on the Hydro 15 are special material. The Clevis pulling
yoke will serve well if assembled properly. You, as the operator, have the duty of checking to see that
this bolt and nut are tight and in place. The Bolt will have six marks on top indicating a grade 8. The nut
should be pulled up tight and there should be spacer washers between the tow clevis and the draw bar,
these are to take up the space between the clevis and draw bar. The owners manual will have a drawing
showing this connection in section 5, page 11.
3. Check the sight glass on the oil tank of the Hydro 15. It is located on the front wall of the hydraulic
tank. Oil should be visible in the sight glass when the mower is level (sitting level). USE CAUTION; If
the oil is low, clean the oil cap and the area around it of any debris that might fall into the oil tank. Push
the relief valve to relieve any pressure from tank, the oil tank is a closed system and designed to retain
approximately 12 psi. Oil should be added by removing the spin-on the air breather (do not do this with
any pressure in tank) and remove the pressure relief from the top of the tank.
4. When adding oil to the system of the Hydro 15, keep grass, dirt, dust and other foreign matter
away from the filter tube and oil container. Replace the relief valve and spin-on breather after oil is added.
5. The Oil information is found in section 5, page 3. Oil type is listed there under Exxon (Nuto H-
100), Gulf (harmony 100 AW) and Shell (Tellus 100) or equal.
6. Check the Hydro 15 blades, bolts and blade bar for signs of wear or loosening. Section 5, page
5 of the manual has detailed information on this procedure.
7. Check the six bolts that hold each spindle to the Hydro 15 deck. This information may be found
in section 5, page 4.
8. Inspect the hydraulic system in general and spot any oil leaks that may be in the system. Tighten
any fittings that may have become loose. The fittings on the hydro 15 are a flair type and hold very well
but must not be over tightened.
9. The Hydro 15 will do an excellent mowing job if it is properly setup. To check the setup on the
Hydro 15, pull the mower (connected to the tractor) to a level (paved preferred) area and lower the wings
from the transport position. Set the mower (center and wings) down to the lowest position. Your Hydro 15 manual has this information in section 4, pages 5 & 6.

Continued Next Page

Information Bulletin 060795 Continued from previous Page
10. There is a Valve attached to the tractor within easy reach of the operator. The three spool valve
is for control of the Hydro 15 level lift and wing angle, with one handle for each wing. Two
segments of the valve have "detent" that will allow the wings to "float" on the contours of the
ground surface. The other valve segment is spring loaded to center on "off" position. This valve
segment is connected to the level lift system. The Hydro 15 may be raised to transport height
and the control valve may be released. The Hydro 15 will remain at the set height until the control
valve handle is moved by the operator.
11. Move the mower to a clear area, lower the wings. Slowly engage the PTO (540 RPM) control
with the tractor engine running at 1000 RPM engine speed (Not PTO Speed). Do not try to set
the mower down in the material you are going to mow, this would be like trying to start your car in high
gear going up a hill. Start the Hydro 15 in a clear mowing area or raise the mower (with the level lift
system) up out of the grass. Increase tractor engine RPM to the Tractor Manufacturers recommended
engine speed to produce 540 PTO RPM, then you may begin mowing. Operators instruction and trouble
shooting guide may be found in section 4, pages 10, 11 & 12. CAUTION ! Tractors now have a "brake"
on the PTO Shaft. If the tractor RPM is above idle when the PTO is disengaged, excessive strain is
placed on all components of the drive system. Therefore the only correct procedure to use when
disengaging the PTO is to reduce the tractor engine speed to an idle before moving the PTO handle
to the "off" position.
12. With PTO turning , lower the level lift system to the desired height, place wing control levers in
the "float" position. The Mowing ground speed will vary and can be determined by the conditions of
the area, roughness of terrain, vegetation thickness, type of vegetation. The operator will have to select
the gear for ground speed that gives the best mowing job.
13. The Hydro 15 has a relief valve on each of the three hydraulic motors. These relief valves will
emit a high squeak when activated. When a relief valve is activated the forward progress should be
stopped. If the relief valve was activated the forward progress should be stopped. If the relief valve was
activated due to excessive forward ground speed for the amount of vegetation encountered, a lower
gear of tractor should be selected. If relief is activated due to foreign material becoming entangled in the
blade or carrier, the foreign material must be removed afterthe mower has been completely shut
down and tractor engine has been turned "off". Use the proper procedure to secure the tractor so it
cannot be started until all work is done and every one is clear.
14. Use the owners manual / parts book to keep a record of the maintenance records on the Hydro
15. Daily and weekly sample forms are found in section 5, pages 2 & 7.
NOTE:
Tractor RPM & PTO, We have heard operators say, "I run my tractor at a low engine RPM to
save the engine". This is erroneous thinking! The tractors are designed for continuous operations at the
rated PTO shaft speed of 540 RPM. Always keep the tractor running at the speed that will result in 540
RPM at the PTO shaft.
We have seen operators running in third or fourth gear and traveling on really rough ground
throttle back the engine speed down in order to slow the forward speed, this isn't a proper procedure.
The proper procedure is to shift the tractor to a lower gear that will give a slower ground speed while
maintaining the tractor engine RPM to maintain a 540 RPM PTO Speed.
Section 5, page 3 has exact details of the filter change procedure. Two replacement filters,
P/N 00751529 and a 5 gallon container of oil is shipped with each new Hydro 15. Use this oil to refill
reservoir after filters are changed. See section 5, page 12 for Filter change procedures.

New Sealing Washers Used on Plugs of Speed Increaser:
Speed Increaser Assembly P/N 00768991: Plug Seal Update, There have been some
isolated reports of the case plugs backing out on the above mentioned Speed Increasers, causing
loss of oil and cataastrophic failures of the gearbox.
Test conducted by Alamo Industrial revealed when ambient temperatures exceeded approximately 100° F. the nylon and plastic washers on the plugs would get soft or melt, this allowed the plug
to back out.
We have contacted our supplier of these parts and had the material specifications changes
for these washers. The new washers are made of aluminum istead of the old nylon or plastic. The
part number for the washers (P/N 00754536 and 00755424) will remain the same as there will be no
changes in the way they fit, only in the type material they are made out of.
All units operating in warm temperature of 100° F. or higher should be changed right away
to prevent plugs from backing out.

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.

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.

Spindle Bearing Lubrication Update:
Normal maintenance of the # 02960553B, 02960553C and 02968859A Spindle assemblies
has included the addition of NLGI 000 grease to provide proper lubrication of the bearing assemblies.
Due to repeated customer requests, this lubrication requirement has been changed to NLGI EP, #
2 Lithium Wheel Bearing Grease.
Implementation of this grease will allow
improved lubrication especially to the top bearing
as well as substantial improvement of the daily
maintenance requirements.
Spindle Assembly
Conversion:
1. Remove the existing fill plug from the
spindle housing and discard it. (this is the
lower plug in figure 1)
2. Install a standard 1/4" fine thread grease
zert into the fill plug port as shown in figure 1.
3. Remove the Vent plug (Top plug in figure 1)
4. Fill the housing with NLGI EP, # 2 Lithium Grease or equivalent from a standard grease gun
until the new grease is seen in the vent plug hole. (Approximately 2 standard grease tubes
will be required when Spindle Assembly is empty).
5. Clean off any excess or over flow grease and reinstall vent plug.
6. Maintain proper lubrication with 5 pumps of grease into the spindle every 8 hours of use. This
will keep the Spindle bearings lubricated.
7. Always clean excess Grease away from Spindle after greasing Spindle.
