Automatic Controlled Traction (ACT)

Automatic Controlled Traction (ACT) applies a preset amount

of torque to both rear wheels even if one starts to slip. A

transmission without ACT will lose traction completely if one

rear wheel starts to slip. This preset torque is just enough to

give additional traction, and still let the wheels turn at different

speeds in a tight turn without damage to the lawn.

Under certain circumstances, the ACT system limit can be

exceeded, and one of the rear tires may slip. For example, if

you turn up a hill, when you accelerate. This is normal. If you

start to lose traction, do not speed up. Instead, slow to stop,

straighten the steering wheel, and slowly accelerate. Stopping

the tractor lets the transmission get more traction.

Cruise Control

To engage:

• Push down on the cruise control lever (S, Figure3) until

the desired speed is reached.

To disengage:

• Pull back on the cruise control lever or push the brake

pedal (P).

Mowing in reverse can be hazardous to bystanders.

Tragic accidents can occur if the operator is not alert to

the presence of children. Children are often attracted to

the machine and the mowing activity. Never assume that

children will remain where you last saw them.

• Keep children out of the operating area and under the

watchful care of a responsible adult.

• Do not carry passengers, especially children, even

with the blade(s) shut off. Children can fall off and be

seriously injured or interfere with the safe machine

operation. Children who have been given rides in

the past can suddenly appear in the mowing area for

another ride and be run over or backed over by the

machine.

• Do not mow in reverse unless absolutely necessary.

Always look down and behind before and while you

mow in reverse.

• If the machine mows in reverse without the Reverse

Mowing Option activated, see a Briggs & Stratton

Authorized Service dealer immediately.

Reverse Mowing

The Reverse Mowing Option (RMO) lets the operator mow in

reverse.

1. Engage the Power Take-Off (PTO) (O, Figure8).

2. Turn the RMO key (A) to the ON position.

3. The L.E.D. light will come on.

Note:The RMO deactivates each time the PTO is

disengaged.Remove the key to prevent access to the RMO.

Maintenance
