Proper wheel slip through the control of tractor weight and drawbar pull will give higher tractive efficiency that reduces fuel consumption. ROPS load rating can be determined from a plate or decal on the cab. Operate at the proper inflation pressure. The maximum load that a tire can carry depends on inflation pressure. Low inflation pressures are for less tire load or tire sidewall buckling may occur.
Most efficient operation occurs at the lowest pressure that produces satisfactory tire life.
With reduced load and lower inflation pressure, soil compaction is reduced and tractive performance improves. Minimum inflation recommendations were lowered from 12 to 6 psi by tire manufacturers in 1992. The key is to use the correct inflation pressure. First, determine the tractor weight and the weight distribution between the two axles. If a heavy mounted implement or equipment is used, weigh the tractor with it attached and in the transport position.
