mower frame to get access to the transmission system.
Wear in the reel drive chain is compensated for by the
sprung chain tensioner shoe. As the motor/clutch and
clutch/roller chains stretch, the clutch assembly must
be moved in order to obtain the correct slack in each
chain. The nut at the bottom of the clutch mount plate
must be slackened and the clutch assembly moved
forward and down to take out the excess slack. There
should be approximately 3-5mm of slack in each chain
for correct adjustment. It would be worthwhile at this
stage to inspect the bearings and sprockets for excessive
wear. Replace worn or damaged parts with genuine
LawnMaster Dual-Drive Reel Mower components before
further use.

Flexible coupling

Remove the drive shaft cover, located on top of the
lawnmower, and inspect the flexible coupling spider for
signs of wear every 50 hours of operation.

General lubrication

Grease nipples are provided in the cutting cylinder
bearings (and roller bearing housings on Golf and
Sports models) and should be greased every 25 hours.
The drive chains should have a small amount of grease
applied to each one to prevent seizure and prolong the
chain life.

Clutch cable adjustment

The Reel Mower operating levers feature a Hold In
interlatch that allows single handed operation of the
mower. After several hours of operation the clutch cables
may require adjustment to obtain the correct drive. This
may be due to either the clutch cable stretching or the
clutch plates wearing, therefore not allowing sufficient
travel on the clutches to engage the drives. There is
adjustment in the cable assemblies to accommodate
the wear. The following procedures should be followed.
Remove the shaft cover and put to one side with the
fasteners.
The reel clutch can be adjusted, with the cable inline
adjuster D . Firstly loosen the reel clutch cable inline
adjuster D , then tighten one turn at a time and re-
check the roller clutch engagement. Continue this
procedure until the reel drive is fully engaged. When the
cable is correctly adjusted, the lever should engage the
'hold in' detent.

D
The roller clutch can be adjusted, with the cable inline
adjuster E and also by the locknut F fitted to the pull
rod.
Firstly loosen the roller clutch cable inline adjuster E
then tighten one turn at a time and re-check the roller
clutch engagement. The correct engagement is achieved
when the lever engages the hold in position with full
clutch engagement. If this adjustment is not attainable
with this method it is necessary to remove the slack
from the system by tightening the locknut F on the
pull rod a turn at a time until the required movement is
achieved.
Once the adjustments to the clutch cables have been
made and the mower drive is correct, finally replace the
shaft cover.

Grass thrower adjustment

The grass thrower will require adjustment in certain
grass conditions or after prolonged use of the mower
as the cutting edges wear. This will be noticeable by the
reduced efficiency to catch grass and to fill the catcher.
