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.

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.
