Problem
There is no machine movement in forward
or reverse.
The machine creeps forward or backward
in neutral.
There is excessive noise in the hydraulic
system.
After an initial period of satisfactory
operation, the machine loses power.
A reel 'knocks' while rotating.
1 reel rotates slowly.
Possible Cause
1. The parking brake is engaged.
2. The fluid level is low.
3. The reservoir has the wrong kind of
fluid.
4. The drive pedal linkage is damaged.
5. The transmission pump is damaged.
6. The transmission bypass valve is open.
7. There is a broken drive coupling.
1. The transmission neutral adjustment is
set incorrectly.
1. A pump is malfunctioning.
2. A motor is malfunctioning.
3. Air is leaking into the system.
4. A suction strainer is blocked or
damaged.
5. The fluid has excessive viscosity due
to cold conditions.
6. The relief valve setting is low.
7. The hydraulic fluid level is low.
1. A pump or motor is worn.
2. The hydraulic fluid level is low.
3. The fluid in the hydraulic system has
the wrong viscosity.
4. The fluid-filter element is blocked.
5. The pressure relief valve is
malfunctioning.
6. The system is overheating.
7. There are leaks on the suction hose.
1. There is a high spot on the reel or the
bedknife due to contact with a foreign
object.
2. The reel bearings are worn.
1. A reel bearing is seized.
2. A motor with incorrect rotation was
installed.
3. The integral relief valves of the motor
are jammed open.
4. The reel is tight on the bedknife.
5. The motor is worn.

Corrective Action
1. Disengage the parking brake.
2. Fill the reservoir to the correct level.
3. Drain the reservoir and fill it with the
correct fluid.
4. Check the linkage and replace any
damaged or worn parts.
5. Have the transmission pump
overhauled by your authorized
distributor.
6. Close the bypass valve.
7. Replace the drive coupling.
1. Adjust the transmission neutral linkage
setting.
1. Identify the noisy pump and service or
replace it.
2. Identify the noisy motor and service or
replace it.
3. Tighten or replace the hydraulic fittings,
particularly in the suction lines.
4. Clean and reinstall the suction strainer,
or replace it as necessary.
5. Allow the system to warm up.
6. Have the relief valve pressure checked.
Consult your authorized distributor.
7. Fill the hydraulic fluid reservoir to the
correct level.
1. Replace the pump or motor as
necessary.
2. Fill hydraulic fluid tank to the correct
level.
3. Replace the fluid in the hydraulic tank
with the correct viscosity-grade fluid;
refer to the Specifications section.
4. Change the filter element.
5. Have the relief valve cleaned and
pressure checked. Consult your
authorized distributor.
6. Check the reel-to-bedknife adjustment.
Reduce the work rate (increase the
height of cut or reduce the forward
speed).
7. Check and tighten the fittings. Replace
the hose if necessary.
1. Remove the high spot with a stone and
back lap to restore the cutting edges.
Severe damage requires grinding.
2. Replace the bearings as necessary.
1. Replace the bearings as necessary.
2. Check the motor and replace it if
necessary.
3. Have the relief valves cleaned and
checked.
4. Adjust the setting.
5. Replace the motor.
