Easy Ballasting Options

RIDE, TRACTION & PERFORMANCE

The University of Nebraska conducted field tests in the

summer of 1999 to compare the effect of traction on

tractors equipped with and without front dual wheels.

The results showed, when pulling drawbar implements,

generally a 65/35 rear/front weight split performed the

best for tractive efficiency with single or front dual

wheels. Hitch mounted implements generally performed

best with a 60/40 rear/front weight split. The test

emphasizes the importance of proper ballasting.

During tractor ballasting, pay attention to:

• The front to rear weight split on the tractor

• Pounds of weight per PTO hp and drawbar hp

• Tire load/inflation values

Proper ballasting minimizes compaction and enhances

tractor performance. Front duals increase the tire-to-

ground contact area and reduce the ground contact

pressure under the front axle. The tractor used for the

field test was equipped with 520/85R46 rear and

480/70R34 front tires. With these tires, the use of front

duals increases the tire-to-ground contact area by 25%.

Lower air pressure (see Load/Inflation Charts) improves

the tire footprint, while reducing the tire to ground

contact pressure and compaction in the field.

FWD Dual Wheel Field Test Results

Two different front weight frames are available

depending on FWD on SuperSteer options. The

weight frames increase front end vehicle weight and

the weights wrap under the chassis providing greater

ground clearance. The front wheels turn behind the

weights and frame for increased visibility and tighter

turning radius.

Two suitcase weight options are available, weighing

40 kg (88 lb) and 100 kg (220 lb).

• When using the large suitcase weights, a

maximum of 16 weights can be installed

• When using the small suitcase weights, a

maximum of 22 weights can be installed
