4.9.1 Tire Inflation
Tire air pressure should be kept according to the regulations.
Four-Wheel Drive Type: Both the front and rear tires are inflated to 0.11–0.14Mpa (16-20 PSI).
When the drive wheel slips you need to shut down the tractor and troubleshoot immediately.
Do not run at high speed on uneven or rough roads. Operate the emergency brake as little as possible.
The tires should be kept clean of fuel, lube oil or other dirt. When dirty, wash or brush them with water.
When the tractor is not going to be run for a long period, it should be jacked up to take pressure off
the front tires.
NOTE:
Excessively low or high tire pressure will shorten the service life of the tires. It will affect
steering and control of the tractor, and could lead to hazardous situations.
