BRUSH BEAST Brush Mower

Service Adjustments

DANGER: Before making any adjustments or servicing

your brush mower, make sure the brush mower is on

level ground, the blades are disengaged, the key is

removed, the engine is off and the spark plug wires are

disconnected from the spark plugs to prevent

inadvertent starting. If maintenance or adjustments are

being performed after operation of the brush mower,

allow the unit to cool since heat build up could cause

severe burns.

Safety System Adjustments

WARNING: Do not bypass, modify, alter, or

disconnect the safety system. Make sure that the

safety interlock system is fully operational each time

before mowing. Failure to do so could present

danger to you and others around you.

There are generally three (3) ways to adjust the

sensitivity of a safety switch. The most appropriate way

to adjust each switch depends upon the application,

location, and the nature of the problem you are

encountering.

Method 1: Adjust location using the mounting

screws

1. Move the blade control lever to OFF.

2. Loosen screws (A) until safety switch (B) moves

freely.

3. Slide safety switch (B) firmly against blade bell

crank (C).

4. Tighten screws (A) and check that safety switch (B)

does not move.

Method 2: Adjust location using adjustment nuts on

switch body

1. Loosen locking nut (C) on the sensor shaft.

2. Adjust switch location by turning the nuts.

3. Tighten the locking nut when proper adjustment is

achieved.

Method 3: Relocate mounting holes

In rare cases where the components become

misaligned, the easiest means of adjusting the location

is to elongate the existing holes or add new holes to

achieve a tighter fit between the activation rod and the

sensor.

WARNING

Hydro System Maintenance

The hydrostatic drives are coupled to the output drives

with a multi-v belt. Occasional retensioning of the belt

may be necessary. If performance decreases or hydro

control handles are activated and the wheels do not

turn, inspect the multi-v belt.

1. Remove the hydro

access panel.

2. Loosen jamb nut at

hydro tensioner.

3. Tighten nut to tighten belt. Belt tension should be

1/16-inch deflection under seven (7) of pressure.

4. Once tension is set, tighten the jamb nut and

reinstall the hydro access panel.
