Mower Operation

Driving the Mower

 

After starting the engine, engage the steering control 

levers and steer as follows:

To go forward,

 push the steering control levers forward an 

equal distance. Figure 3-7

To go in reverse,

 pull the steering control levers rearward 

an equal distance. Figure 3-7

To turn left,

 move the right steering control lever farther 

forward from neutral than the left steering control lever.

To turn right,

 move the left steering control lever farther 

forward from neutral than the right steering control lever. 
Figure 3-7

Zero radius turn,

 move one steering control lever forward 

and the other steering control lever back of neutral. This 
allows the drive wheels to counter-rotate. Figure 3-7

To stop or decrease speed,

 move steering control levers to 

neutral. When going forward pull back gently on steering 
control levers. When going in reverse push forward gently on 
steering control levers.

For emergency stops,

 when traveling forward or rearward, 

place the steering control levers in the park brake position 
immediately.  

To make a three point turn to the right:

 

1.

Move the left steering control lever farther forward 
from neutral than the right steering control lever and 
start the turn. Figure 3-8

2.

Next, pull back on the steering control levers until they 
pass neutral and the machine starts to go rearward. 
Figure 3-8

3.

Pull the right steering control lever farther rearward 
from neutral than the left steering control lever until 
the rear of the machine pivots around. Figure 3-8

4.

Then, push the steering control levers forward until 
they both pass neutral and the machine starts to go 
forward. Figure 3-8

5.

Push the left steering control lever farther forward 
from neutral than the right steering control lever and 
finish the turn. Figure 3-8

 

IMPORTANT:  

Damage to the hydraulic system

 

components may occur with rapid movement of the steering 
controls.

To increase speed,

 increase the steering control lever’s 

distance from neutral. The farther forward the steering 
control levers are from neutral, the faster the mower will 
travel forward. The farther back the steering control levers 
are from neutral, the faster the mower will go in reverse.

Never make sudden stops or reverse direction, 
especially when maneuvering on a slope. The 
steering is designed for sensitive response. Rapid 
movement of the control levers in either direction 
could result in a reaction of the mower that can 
cause serious injury.

DANGER

When moving in the rearward direction push 
forward gently on steering control levers and avoid 
sudden movement. Any sudden movement could 
cause the front of the mower to come off of the 
ground resulting in possible loss of control, 
causing serious injury or death.

Always be aware of what is behind the machine 
before backing up. Do not mow in reverse unless 
absolutely necessary. Always look down and 
behind before and while backing up.
