Page 59: Tires
L3200, WSM G GENERAL 9. TIRES [1] TIRE PRESSURE Though the tire pressure is factory-set to the prescribed level, it naturally drops slowly in the course of time. Thus, check it everyday and inflate as necessary. To inflate the wheel tires, use an air compressor or hand pump.
Page 60: Treads Adjustment
L3200, WSM G GENERAL [2] TREADS ADJUSTMENT CAUTION • When working on slopes or working with trailer, set the wheel tread as wide as practice for the job for maximum stability. • Support tractor securely on stands before removing a wheel.
Page 61: Rear Wheels
L3200, WSM G GENERAL (2) Rear Wheels Rear tread can be adjusted in 6 steps depending on the model. To change the tread 1. Lift the rear tires off the ground. 2. Follow the illustrations below to get the desired tread width.
Page 62: Tire Liquid Injection
L3200, WSM G GENERAL [3] TIRE LIQUID INJECTION Auxiliary weights can be used to increase traction force for plowing in fields or clay ground. Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be used in winter since it freezes at 0 °C (32 °F).
Page 63 L3200, WSM G GENERAL Injection CAUTION • When a calcium chloride solution is used, cool it before pouring it into the tire. • Do not fill tires with water or solution more than 75 % of full capacity (to the valve stem level).
Page 64 L3200, WSM G GENERAL Draining Water or Solution 1. Lift the rear tires off the ground. 2. Turn the tire so that the air valve is at the bottom. 3. Remove the air valve, and drain liquid (liquid can only be drained to the level of the valve and liquid under that level remains inside).
