The following table illustrates some problems which may arise during operation.
FAULT CAUSE MEASURES TO BE TAKEN
Grass ejection insufficient 1. Grass wet
2. Grass too long
3. Cutting height too low
4. Engine speed too low
5. Forward speed too high
6. Build-up of grass inside flail
housing
1. Wait until the grass has
dried
2. Go over the grass twice,
changing the cutting height
3. Increase the cutting height
4. Accelerate to maximum
5. Decrease forward speed
6. Clean the inside of the flail
housing
Machine does not cut the grass
completely
1. Forward speed too high
2. Engine speed too low
3. Grass too long
4. Flails worn or broken
5. Build-up of grass inside flail
housing
1. Decrease forward speed
2. Accelerate to maximum
3. Go over the grass twice,
changing the cutting height
4. Replace the flails
5. Clean the inside of the flail
housing
Machine scalps the ground 1. Cutting height too low
2. Undulating terrain
3. Ground uneven 1. increase the cutting height
2. change
cutting pattern
(e.g. direction)
3. increase cutting height
Belt slips 1. belt tension inadequate
2. Build-up of grass inside flail
housing
3. Belt worn
1. Adjust the belt tension
2. Clean the inside of the flail
housing
3. Replace belt
Machine vibrates excessively 1. Build-up of grass inside flail
housing
2. Belt damaged
3. Flails bent or broken
4. Flail rotor warped
1. Clean the inside of the flail
housing
2. Replace belt
3. Replace flails
4. Replace rotor
Engine overloads during work
operations 1. Engine speed too low
2. Flails worn
3. Forward speed too high
4. Snarl or build-up of grass
on rotor
5. Grass too long
6. Cutting height too low
1. Accelerate to maximum
2. Invert or replace flails
3. Decrease forward speed
4. Remove grass from flail
rotor
5. Go over the grass twice,
changing the cutting height
6. increase the cutting height
Machine tends to run away on
steep banks 1. ground too soft
2. operator cutting at right
angles to bank
1. wait until ground dries
2. work in direction of bank
The cutting unit projects
objects outwards
1. front guard raised
2. front cover open
3. working in reverse gear 1. lower the front guard
2. close front cover firmly
3. only work in forward gear
