SPEED CONTROL BELL CRANK 

The speed control bell crank holds the speed 
control rod in position after a speed has been 
set. The spring washers may become loose 
with normal wear. If the speed control rod 
does not stay firmly in position, adjust the 
speed control bell crank. See Figure 11.
To adjust:

1. Remove cover, fully compress the 

helical spring lock washers with lock 
nut and then back lock nut off, one 
quarter turn.

2. If the speed control rod is still too loose, 

tighten lock nut by small increments 
until it holds its position. Tightening the 
lock nut too much will not allow the 
speed control rod to move at all.

3. Align notch in left hand side of cover 

with bolt and secure with knob.

IMPORTANT: 

 NEVER spray unit with high 

pressure water or store unit outdoors. Store 
mower in a cool, dry, protected location.

Cleaning

Clean unit thoroughly with mild soap and low 
pressure water. Brush off dirt and debris from 
all surfaces. Touch-up all scratched surfaces 
to prevent rust. Matching touch-up paint is 
available from your Gravely Dealer. Do not use 
abrasives, solvents, or harsh cleaners.

Inspection

Inspect mower and repair or replace worn or 
damaged parts to avoid delays when 
beginning use again.
Regularly check all hardware and keep 
fasteners tight. Know unit is in safe working 
condition.

Grass Bag

Wash out grass bag and allow to dry before 
storage. Grass bag may be stored in position 
on mower.

Engine

When storing unit for extended periods of 
time, remove all fuel from tank and carburetor 
(run dry). Refer to engine manual.
