Procedure for Reel Motor Case Drain Check:
1.Make sure hydraulic oil is at normal operating tem- perature by operating the machine for approximately 10 minutes. Make sure the hydraulic tank is full.
2.Make sure machine is parked on a level surface with the cutting units lowered. Make sure engine is off and the parking brake is engaged.
CAUTION
Operate all hydraulic controls to relieve system pressure and avoid injury from pressurized hydraulic oil.

3.On suspected bad motor, clean hose connection and disconnect hose from motor that returns to the man- ifold (see table).
IMPORTANT: Make sure oil flow indicator arrow on the flow gauge is showing that the oil will flow from the motor through the tester and into the hose.
4.Install tester in series with the motor and the discon- nected return hose. Make sure the flow control valve is fully open.
5.Make sure backlap knob on the valve block is in the mow position.
6.One person should sit on the seat and operate the machine while another person reads the tester. Start en- gine and move the throttle to full speed (3200 100 RPM).
CAUTION
Keep away from reels during test to pre- vent personal injury from the rotating reel blades.
7. Engage reels by pulling the knob on the instrument panel out. While watching pressure gauges, slowly close flow control valve until a pressure of 1200 PSI is obtained.
8. Disengage cutting units and stop engine. |

9. Clean hose fitting and disconnect hose from case |
| |
drain on the manifold block (see table). Plug the man- |
| |
ifold port. |
| |
10. Put case drain hose into 1 quart container gra- |
| |
duated in ounces (1 liter container graduated in millili- |
| |
ters). |
| |
11. One person should sit on the seat and operate the |
| |
machine while another person holds the hose and reads |
| |
the tester. Start engine and move the throttle to full |
| |
speed (3200 100 RPM). | Hydraulic System | |
12. While sitting on seat, engage cutting units by pulling | ||
| ||
the knob on the instrument panel out. Make sure gauge |
| |
pressure still reads 1200 PSI. After 15 seconds, push |
| |
knob on the instrument panel in to disengage cutting |
| |
units. Stop the engine. |
| |
| ||
13. Measure the amount of oil collected in the container. |
| |
Divide the number of ounces collected by 32 to get gal- |
| |
lons per minute. (Divide the number of milliliters col- |
| |
lected by 250 to get liters per minute). |
| |
14. Disconnect tester from motor and hose. Reconnect |
| |
hose to the pump. |
| |
15. Remove cap from manifold fitting. Reconnect case |
| |
drain hose to the motor. |
| |
16. If flow was greater than 0.7 GPM (2.6 LPM), repair |
| |
or replace the reel motor as necessary. |
