Belt Tension
IMPORTANT: Belt tension should be rechecked on
new belts after approximately 20 hours of operation.
!
CAUTION
To avoid minor or moderate injury:
The belt drive system is under spring tension. Use care when
servicing the system to avoid injury caused by forces built up
in the spring.

Belt Tension
Figure 2-1
Refer to Figure 2-1:
1.
To check tension, apply force at arrow A with a
tension tester until the belt is deflected 1/4" (6.4 mm).
The force required to get this deflection should range
from 7 to 10 lbs (3.2 to 4.5 kg).
2. Adjust belt tension by adjusting eyebolt (#1) until
correct tension is achieved. This adjustment will
increase or decrease the tension on spring (#2).
3. Excessive tension may lead to premature failure of
belt and drive components. Also, excessive tension
may be a safety hazard to operator and bystanders.
Not enough belt tension may lead to premature
failure of the belt due to excessive slipping.
Center Deck Height Adjustments
These adjustments should be made with mower
hooked-up to a tractor that will be used for field
operations or one having the same drawbar height.

DANGER
To avoid serious injury or death:
Always disconnect driveline from the tractor before servicing
the drivetrain and components powered by the drivetrain. A
person can become entangled in the drivetrain if the tractor is
started and the power take-off is engaged.
!
WARNING
To avoid serious injury or death:
•
Block decks up before making cutting height adjustments.
•
Always follow "Tractor Shutdown Procedure" provided in
this manual before dismounting the tractor.
IMPORTANT: When going over a raised area, make
sure main driveline does not make contact with
mower tongue, especially near hitch end of tongue.
IMPORTANT: Before continuing, read instructions
on raising and lowering decks starting with "U-Joint
Timing" on page 30.
Refer to Figure 2-2:
1.
Position mower on a level surface and adjust hitch
clevis up or down on end of tongue until the tongue is
close to level with the ground. Tire pressure will affect
mowing height. Be sure all tires have proper psi
pressure. See "Tire Inflation Chart" on page 52.
2. Lower mower decks fully down on a flat level surface.
3. Make measurement (A) (top of deck to ground) on all
three decks. Check measurements in Cutting Height
Chart to determine if the decks need to raised or
lowered to obtain preferred cutting height (B).
4. Raise all three mower decks up to an adequate
height and block under the decks to prevent them
from falling during gauge wheel height adjustments.
