TO REMOVE WHEEL (See Fig.  33)

•  Block up axle securely.
• 

Remove axle cover, retaining ring and washers to allow 

wheel removal (rear wheel contains a square key - Do 

not lose).

•  Repair tire and reassemble.
•  On rear wheels only:  align grooves in rear wheel hub 

and axle.  Insert square key.

•  Replace washers and snap retaining ring securely in 

axle groove.

NOTE: 

To seal tire punctures and prevent flat tires due 

to slow leaks, tire sealant may be purchased from your 

local parts dealer. Tire sealant also prevents tire dry rot 

and corrosion.

Your new tractor front wheel toe-in and camber is set at the 

factory and is normal. The front wheel toe-in and camber 

are not adjustable.  If damage has occurred to affect the 

factory set front wheel toe-in or camber, contact a qualified 

service center.
