LUBRICATION
There are 4 pressure lubrication points on the mower.
All are zerk type grease fittings. Use a quality light
grease at these points. The bronze clutch collars each
have a grease fitting. These are located at the front of
the tractor on the left and right sides underneath the
main guard. Lubricate with 1 or 2 shots of grease every
10 hours of operation. The caster post has a fitting. It is
located just above the attachment point of the caster
wheel. Lubricate this every 20 hours of operation. The
last fitting is located on the differential, between the
rolls or tires depending on how your mower is
equipped. Lubricate this every 100 hours of operation.
Keep all chains well lubricated with a thin lubrication
oil. It is best to lubricate them after each mowing or
every 4 hours of use. This prevents rusting while
standing idle and allows the oil to penetrate to the pin
and bearings by capillary action. When a chain is op-
erated
without lubricant, the chain will wear
prematurely and the elongated chain will in turn wear
the sprockets to conform to the pitch of the chain.
Worn chains make expensive repairs because the
sprockets as well as the chains must be replaced.
Proper lubrication will give you many years of
trouble-free service.
CLEANING AND LUBRICATING AFTER
USE
When cutting is finished, clean the machine. It is much
easier to clean now than later. This is a good time to oil
the chains and lubricate the mower, allowing the oil to
penetrate and the grease to flush out grit. If a high
pressure wash down is used it is imperative to lubricate
thoroughly after cleaning.
Inspect the mower for any loose or worn components
and replace if necessary. If you do not understand the
mechanics of the mower, contact your dealer for
service. AVOID spraying water directly into clutch
housing, as this will decrease life expectancy.
ENGINE
The operating and maintenance instructions for the
Kohler, Briggs and Stratton or Honda engine are
explained in a manual furnished by the engine
manufacturer which is included in the information
packet you received with your mower. NOTE: All
engines are shipped WITHOUT fluids and must be
added prior to starting. Refer to engine manual for
instructions about adding oil to the gear reduction
crank case if applicable.
BEARINGS
All parts that constantly rotate are carried on ball
bearings. The reel, clutch shaft, height roller and roller
axle have permanently sealed bearings. The reel chain
idlers and caster wheel are carried on semi-precision
bearings and may require lubrication. Pivot points such

as reel link arms, reel bearing housings, etc. have
sintered bronze bushings.
TRACTOR ROLLS
The tractor rolls are in reality hard rubber tires. They
are mounted on a single axle which drives them
through differential gears. The differential is
composed of two steel bevel gears and two steel
pinions with hardened teeth, fully enclosed and
packed in grease.
TRACTOR TIRES
There are four pneumatic tires in place of the rollers.
Tire pressure should be set at 10 psi cold.
TRACTOR CHAIN TENSION ADJUST-
MENT
On occasion it is necessary that slack be taken up
on the tractor chain. Tension should be adjusted so
that there is a slight movement by hand pressure.
Excessive tension will result in loss of power and
premature wear on components. To adjust the
tractor chain, loosen the bolt on the chain adjuster
and push on the plastic block until the desired
tension is achieved. (See figure below) Tighten the
bolt to secure the tensioner block. When the chain
has elongated to the point of using all of the adjust-
ment, it will be necessary to take out a link of chain.
