Removal
Remove the accumulated grass from bottom side of mowing mechanism. Make sure that the knives
are sharp and not deformed. Check the tightening of knives. Check if the mowing mechanism height setting
upcorresponds to the data in the chapter 6.1.17 and 6.2.15. If not, carry out the new setting up. Check the tension
of drive belts according to the chapter 7.14 and 7.16. If need be, carry out the adjustment of tensioning. Check the
shafts of knives. If they are damaged or excessively worn out, replace them. Check the bodies of bearings for
a possible damage. With respect to the finding, carry out the repair or replace them.
An unmown stripe may remain when mowing dense grass or grass with excessively wet surface.
The travel speed should be adjusted to the mowing conditions by selecting the suitable gear. The engine should
run with the gas control lever in the "MAX" position. Check the knives if they are sharp and undamaged.
If necessary, replace them. Check the tension of drive belts according to the chapter 7.14 and 7.16. If need be,
carry out the adjustment of tensioning.Check the bodies of bearings for a possible damage. With respect to the
finding, carry out the repair or replace them.
Check the setting-up of the height of mowing, and if need be, adjust it.
Sods are torn out more often on uneven surfaces.
Check the bodies of bearings for a possible damage.
With respect to the finding, carry out the repair or replace them.
Check if the knives are not bent. If need be, replace them.
Remove the accumulated grass from the mowing mechanism bottom side.
In a wet weather, the tunnel and lower side at the outlet from the mowing mechanism may get clogged with grass.
Do not mow the wet grass. The travel speed should be adjusted to the conditions of mowing by selecting the
suitable gear. The engine should run with the gas valve fully open. When mowing high grass, first, mow once with
the mowing mechanism in the high position, then mow again with the mowing mechanism in normal position.
Adhere to the data stated in the chapter 6.4. Check the tension of the drive belts according to the chapters 7.14
and 7.16. If need be, carry out the adjustment of the tensioning.
Make sure, especially after replacement of the knife, that the knife is mounted correctly.
A damage to the mowing mechanism drive belt may occur when it jumps out of the pulley during machine
running. If it jumps out even after the check according to the following steps, it has to be replaced.
- Check the tension of drive belt according to the chapter 7.14. If need be, carry out the adjustment of tensioning.
- Check the belt guiding.
- Check the setting up of the height of mowing, if need be, adjust it.
- Find out if a foreign object is not obstructing the running of the belt. If it is so, remove the foreign object.
- Check all the pulleys. Bent or cracked pulleys could cause problems. If need be, replace them.
- Check the inside surface of the pulley fixed on the engine. If it is rough or there are cracks on it, it is neces-
sary to replace the pulley.
- Check the wear of tensioning mechanism components. If need be, replace the worn out components.
If the grass is too high or wet, the mowing mechanism drive belt may slip.
Check the belt for wear. If it is worn out, replace it.
Check the tension of drive belt according to the chapter 7.14. If need be, carry out the adjustment of tensioning.
Check the tension spring of tightener of the mowing mechanism drive belt.
Replace the stretched or damaged spring.
Check all places of the belt guiding.
Find out if a foreign object is not obstructing the running of the belt. If it is so, remove the foreign object.
Check the pulleys. If they are damaged, replace them.
Check the setting-up of the height of mowing, if need be, adjust it.
Check the tension of drive belt according to the chapter 7.14. If need be, carry out the adjustment of tensioning.
Check whether the belt is worn out or damaged. If it is so, replace it. If it is slack, tension it.
Check the spring of the tensioning mechanism. Replace the stretched or damaged spring.
Find out if a foreign object is not obstructing the running of the belt.
If it is so, remove the foreign object.
Check the tension of drive belt according to the chapter 7.14. If need be, carry out the adjustment of tensioning.
If it is not possible to tension the belt more due to its considerable wear, fit on the new belt.
Find out if a foreign object is not obstructing the running of the belt. If it is so, remove the foreign object.
