Replace the wire or repair with electrician’s tape if 
the wire strands have not been damaged. Also look 
for a wire pinched between body panels, burned by 
the exhaust pipe or muffler, or rubbed against a 
moving part.

•

Stop the rider mower and engage the parking 
brake. Remove ignition key. 

•

Pivot the hood assembly up. Disconnect the spark 
plug wire and ground it.

•

Pull the fuse out of the lead wire. 

•

Replace with new automotive fuse.

•

Make sure to reconnect the spark plug wire before 
pivoting the hood assembly back.

•

Always observe safety rules when performing any 
maintenance.

•

The warranty on this rider mower does not cover 
items that have been subjected to operator abuse 
or negligence. To receive full value from the 
warranty, operator must maintain the rider mower 
as instructed in this manual. 

•

We do not recommend the use of pressure washers 
or garden hose to clean your unit. These may 
cause damage to electrical components, spindles, 
pulleys, bearings or the engine. The use of water 
may shorten life of your rider mower and reduce its 
serviceability. 

Always stop engine and

disconnect spark plug wire before any
maintenance or adjustments.   

•

Remove the 5/8’’ hex flange nut which holds the 
blade to the blade spindle.

•

Remove blade from the spindle. See Figure 17.

•

When sharpening the blade, follow the original 
angle of grind as a guide. It is extremely important 
that each cutting 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/or cause personal injury.

•

The blade can be tested for balance by balancing it 
on a round shaft screwdriver. Remove metal from 
the heavy side until it balances evenly.

•

Before reassembling the blade to the unit, lubricate 
the spindle with light oil (or engine oil).

•

Be sure to properly align “star” fitting on blade with 
“star” on spindle.

•

When replacing the blade, be sure to install the 
blade with the side of the blade marked “Bottom” (or 
with part number) facing the ground when the 
mower is in the operating position.

•

Blade Mounting Torque:

 

70/90 foot-pounds 

maximum.

NOTE:  To ensure safe operation, all nuts and bolts
must be checked periodically for correct tightness.

Your rider mower has a plastic oil drain sleeve, packed
with the loose parts, for draining oil from the crankcase. 

•

To drain the oil, snap small end of the oil drain 
sleeve onto oil sump. See Figure 18.
