TROUBLE SHOOTING
Refer to page 16 of this manual for trouble shooting infor­
mation.
CUTTING BLADE
When removing the cutting blade for sharpening or replace­
ment, protect hands by using heavy gloves or a rag to grasp
the cutting blade. Remove the bolt and bell washer which
hold the blade and adapter to the engine crankshaft.
Remove the blade and adapter from the crankshaft.
If the blade or blade adapter needs replacing, remove the
two small bolts, lock washers and nuts which hold the blade
to the adapter.
WARNING: Periodically inspect the blade
adapter for cracks, especially if you strike a
foreign object. Replace when necessary.
When sharpening the blade, follow the original angle of
grind as a guide. It Is extremely important that each cut­
ting edge receives an equal amount of grinding to prevent
an unbalanced blade. An unbalanced blade will cause
excessive vibration when rotating at high speeds, may
cause damage to the mower and could break, causing per­
sonal injury.
It is recommended that the blade always be removed from
the adapter for the best test of balance.
The blade can be tested by balancing it on a round shaft
screwdriver. Remove metal from the heavy side until it bal­
ances evenly.
Before reassembling the blade and the blade adapter to the
unit, lubricate the engine crankshaft and the inner surface of
the blade adapter with light oil. Lubricating the bolt holes,
bolts and inner surface of the nuts with light oil is also rec­
ommended. A 4 oz. plastic bottle of light oil lubricant is
available. Order part number 737-0170. Engine oil may also
be used.
When replacing the blade, be sure to install the blade with the
side of the blade marked “Bottom” (or with part number) fac­
ing the ground when the mower is in the operating position.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
Blade Adapter Bolts: 200 in. lbs. min., 350 in. lbs. max.
To Insure safe operation of your unit, all nuts and bolts must
be checked periodically for correct tightness.
DECK
The underside of the mower deck should be cleaned after
each use to prevent a buildup of grass clippings, leaves, dirt
or other matter. If this debris Is allowed to accumulate, it will
invite rust and corrosion, and may cause an uneven dis­
charge of grass clippings at the next cutting.
The deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug wire
is disconnected).
ENGINE
Refer to the separate engine manual for engine mainte­
nance instructions.
