Tongue Clevis & Leveling Control Rods Components:
1.
Make certain the mower and tractor are secured in a safe and proper parked position, hydraulic (axle
and wings) lowered or secured by the transport bars. Make certain that tractor is safely parked according to
tractor manufacturers recommendations. Tractor should be secured (or dis-abled) in a way that it cannot be
started unless the servicing technician is ready for it to be started.
Never get under any equipment unless
it is secured and supported by sufficient jack stands, DO NOT depend on hydraulics or brackets to support
equipment if you are going to be under it, this is important!
See the Operators Manual for recommended
Maintenance schedules and recommendations.
2.
Tractor Draw Bar connection, the mower must be connected to the tractor draw bar before the mowing
height can be adjusted. This mower uses a swinging clevis that is designed to be bolted to the draw bar
(figure
1),
This Bolt, Washers and Locknut was supplied with mower and should be replaced with same
components it required. The tongue clevis must be connected to the tractor draw bar using this bolt, washer
and lock nut
(figure 2)
. The tongue clevis will not operate correctly with using a drop pin
(figure 3).
The drop pin
will cause damage to the clevis and draw bar. Some drawbars will have a hole that is larger than the bolt in the
clevis, it is recommended these holes be fitted with a connex bushing to adapt the draw bar hole to the size
of the bolt to hold the clevis as parallel to draw bar as possible
(figure 2)
. The spring washers also act as
wear washers, the qty of washers will vary from tractor to tractor but all need to have washers between clevis
and draw bar for wear.
(figure 1 & 2)
. Tighten the Nut onto the Bolt (
150ft./lbs.)
so that it holds the Clevis
parallel with the draw bar
(figure 2)..
