Belt Drive Adjustment
33 lbs pressure = less
than 1” deflection
Rotor Drive Belt Adjustment
The rotor drive belts, drive by the
HPTO clutch, drive the rotor.
These two belts turn when the
clutch is engaged.
The belts tend to stretch after the
first or second bag. Adjustment
may be required. Test deflection
first (see below). Adjust the en-
gine skid to tighten the belts.
1. Mark the nuts to track the num-
ber of turns. A large wrench is
supplied with your Ag-Bagger
® for
doing this adjustment.
2. Loosen nut (B) at each corner
of the engine frame.
3. Turn nut (A) equal number of
turns at each corner of the en-
gine frame in the same direction.
This will help keep the engine skid
level. Actual adjustment may only
take 1/8 to 1/4 turn.
After the first adjustment, the
drive belts should not require
more adjusting. Follow these ten-
sion standards.
- Ideal tension is the lowest ten-
sion at which the belt will not slip
under peak load conditions.
- Check tension frequently dur-
ing the first 24-48 hours of run-
ning the Ag-Bagger
® . Make sure
the belt is not slipping.
- Over tensioning shortens belt
and bearing life.
- Keep belts free from foreign
materials, which may cause slip-
ping.
- Make belt inspection on a peri-
odic basis and tighten when slip-
ping.
- Never apply belt dressing, as
this will damage the belt and
cause early failure.
- For this application, the drive
belt should have a deflection of
less than 1 inch when @ 33 lbs
of pressure are applied at the
middle of the span.
