Adjusting the Lift Arm Down
Pressure
The down pressure spring on each cutting unit lift arm can
be adjusted to compensate for different turf conditions.
Increased down pressure will help keep the cutting units on
the ground when mowing at higher speeds and helps
maintain a uniform height-of-cut in rough conditions or in
areas of thatch build up.
Each down pressure spring may be adjusted to one of four
settings. Each increment increases or decreases down
pressure on cutting unit by 8 lb.
1. Position machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes, and
remove key from ignition switch.
2. Remove floor plate in front of seat and open the hood to
gain access to all 5 springs.
Springs are under tension.
Use caution when adjusting.
Caution
3. Place an open end wrench on the hex shaft of the spring
bracket (Fig. 32).
4. Remove the capscrew and locknut securing retaining
bracket (Fig. 32), while rotating hex shaft to relieve
spring tension.

5. Move spring bracket to desired location and install
capscrew and locknut, while rotating hex shaft to
relieve spring tension.
Towing the Traction Unit
If it becomes necessary to tow the machine, tow it forward
only, for a short distance and at a speed no greater than 3
mph.
Important If these towing limits are exceeded, severe
damage to the hydrostatic transmission may occur.
To tow a disabled machine:
1. Loosen and remove capscrews securing the drive shaft
to the engine drive coupler. Loosen capscrews clamping
drive shaft to transmission (Fig. 33). Remove drive
shaft.

Important If drive shaft is not removed before towing,
the transmission input shaft will not be able to rotate, thus
not allowing the transmission to maintain its internal
lubrication. Severe damage to the hydrostatic transmission
may occur.
2. Attach a suitable chain, strap or cable to the center of
the front frame member (Fig. 34).
