3-Point Hitch Adjustments
The 3-point hitch system on this mower has been
designed for front to back flotation when mowing on
uneven terrain. Adjust tractor’s top center link to place
the upper hitch pin vertically above or slightly behind the
lower hitch pins. The mower should be run with the back
15 degrees lower than the front.
The hitch can also be adjusted from side to side by
turning the adjustment handle. Turn handle until you
have achieved your desired location. Refer to Figure 3-2.

Belt Tension
!
CAUTION
Belt drive system under spring tension; use care to avoid
bodily harm!
The Belt tension should be checked after the first 20
hours of use. And then every 40 hours of use.
1. To check tension apply approximately 22 pounds of
pressure half way between the pulleys. There should
be approximately 3/8” of deflection. Tension on the
belt can be adjusted with the belt tension bolt. Turn
the bolt until desired tension is achieved. When the
belt has the correct tension the gearbox should be
adjusted so that the gearbox extension is running
straight (parallel) with the flail mower. Loosen bolts at
the bottom of the gearbox and move gearbox until
gearbox extension is running straight. Refer to
Figure 3-3.

2. If there is excessive deflection the belts should be
replaced. Refer to “Belt Installation” Figure 5-1.
3. Excessive tension on the belt may lead to premature
failure of belt and drive components.
!
WARNING
Excessive tension on the belt may lead to premature failure of
belt and drive components. Excessive tension on the belt may
also lead to a safety hazard to the operator or bystanders.
