2.11 Tire Usage and Assembly/Disassembly
2.11.1 Tire Use
•
The Tire is a consumable. Attention should be paid to its use and maintenance in order to prolong its
service life.
•
The tire has a specified loading value. If overloaded, the tire can wear excessively and possible rupture.
•
Running a tire below its recommended pressure will cause the tire to wear unevenly and make the tractor
difficult to operate. Pressure in the tire should be measured with a pressure gage in ambient temperature.
Don't measure tire pressure immediately after operation because the tire will heat during use. Improper
operation can wear or damage the tires prematurely. Avoid going over obstacle at high speed, emergency
stopping or hard steering. When running over a gravel road, tire slippage should be avoided as much as
possible.
•
During use, the tires should be kept clean of any oil, acid, alkaline chemicals or corrosives. Keep the tires
out of bright sunshine as much as possible, in order to avoid rubber aging and degrading.
•
The front wheel alignment and toe-in should be checked regularly for correctness, in order to avoid tire
wear. When tires wear is nonuniform, the left and right tires can be switched.
Important notes: The inflation pressure for the front and rear tires on a 4-wheel drive tractor should be the
same in order to prevent the tires from being worn.
2.11.2 Tire Removal and Refit
Tire Removal
Special tools are needed to assemble and disassemble a tire. Contact a qualified tire service center to
replace tires.
WARNING: When inflating the tire, never remove the lug nuts from the hub. This could cause the tire to fall
off and may result in damage to the tractor and serious personal injury.
2.12 Counterweight
Counterweight is added or reduced according to the requirements of tractor. When traction force has to be
increased for operating in a dry field or for transport operations, counterweight should be added. When the
tractor is used in a hilly area, the front counterweight should be increased appropriately to maintain traction.
Rear counterweights are round iron castings with the weight being per piece is 68lbs. Two pieces can be
installed, respectively making the total weight of the rear counterweight 136lbs. Each front counterweight is
20lbs. and a total of six pieces can be mounted, with the total mass of front counterweight at around 120lbs.
