in neutral.
1. The transmission neutral adjustment is
set incorrectly.
1. Adjust the transmission neutral linkage
setting.
1. A pump is malfunctioning.
1. Identify the noisy pump and service or
replace it.
2. A motor is malfunctioning.
2. Identify the noisy motor and service or
replace it.
3. Air is leaking into the system.
3. Tighten or replace the hydraulic fittings,
particularly in the suction lines.
4. A suction strainer is blocked or
damaged.
4. Clean and replace the suction strainer
or renew it as necessary.
5. The fluid has excessive viscosity due
to cold conditions.
5. Allow the system to warm up.
6. The relief valve setting is low.
6. Have the relief valve pressure checked.
Consult your authorized distributor.
There is excessive noise in the hydraulic
system.
7. The hydraulic fluid level is low.
7. Fill the hydraulic fluid reservoir to the
correct level.
1. A pump or motor is worn.
1. Replace parts as necessary.
2. The hydraulic fluid level is low.
2. Fill hydraulic fluid tank to the correct
level
3. The fluid in the hydraulic system has
the wrong viscosity.
3. Replace the fluid in the hydraulic tank
with the correct viscosity-grade fluid;
refer to the Specifications section.
4. The fluid-filter element is blocked.
4. Change the filter element.
5. The pressure relief valve is
malfunctioning.
5. Have the relief valve cleaned and
pressure checked. Consult your
authorized distributor.
6. The system is overheating.
6. Check the reel-to-bedknife adjustment.
Reduce the work rate (increase the
height of cut or reduce the forward
speed).
After an initial period of satisfactory
operation, the machine loses power.
7. There are leaks on the suction hose.
7. Check and tighten the fittings. Replace
the hose if necessary.
1. There is a high spot on the reel or the
bedknife due to contact with a foreign
object.
1. Remove the high spot with a stone and
back lap to restore the cutting edges.
Severe damage will require grinding.
A reel knocks while rotating.
2. The reel bearings are worn.
2. Replace the bearings as necessary.
1. A reel bearing is seized.
1. Replace the bearings as necessary.
2. A motor with incorrect rotation was
installed.
