STENSBALLE rotary mowers
Operating Instructions
GB
Maintenance and storage
The rotary mower is fitted with 2 or 4 V-belts which are tightened with
the gear/engine bracket.
After the first 5 hours of use, check that the V-belts are tight enough.
Tighten them if necessary. Then check after every 40 hours of
operation that the V-belts are tight enough and tighten them if
necessary.
New V-belts will stretch a lot during the first few hours of use.
You must therefore retighten the V-belts after 5 hours of use.
1. Make sure that the tractor engine has stopped and the PTO output
is disengaged.
2. Remove the outer shielding/guards.
3. Unscrew the bolts in the gear bracket and tighten the belts by
adjusting the clamping bolt on the gear bracket, so that the free
section of the belts can be deformed by approx. 3 cm in either
direction by hand.
4. Then retighten the gear bracket.
5. Bolt the shields firmly back in place.

the clamping bolt passes through the hole in the front of the gear
bracket plate.
6. Insert the 4 set screws in the gear bracket and put the nuts on
without tightening them.
7. Attach the V-belts on the outer pulleys. Check that the belts are
sitting in the right guides.
