SECTION 2 - OPERATION

Weight on Buhler Versatile 4WD tractors is to be
added in the form of liquid ballast to the tires or by
using the front or rear weight kits available.
Once the weight per axle of additional ballast is
determined, the preferred method of adding this
weight is to use as much dry weight (i.e., front
and rear weight kits) before liquid ballast is
added to the tires. This will allow ballast to be
easily removed or installed, depending on
varying needs. Also, by reducing the liquid
ballast inside of a tire, more benefit can be
derived from the construction of the tires. When
liquid ballast is installed inside of a tire, either
bias ply or radial, some of the cushioning action
of the tire is reduced and the ability to adjust tire
air pressure within aspecific range is diminished.
These are important factors when trying to
eliminate c oncerns with wheel slippage and
“power hop.”
The front weight kit can have either thirty-nine 30
kg (67-lb.), suitcase-style weights and, along
with its brackets and hardware, weighs
approximately 1300 kg (2,860 lbs.). Or twelve 30
kg (67-lb.), suitcase-style weights and, along
with its brackets and hardware, weighs
approximately 443 kg (934 lbs.). Most
applications will not require front weight
packages.
Front weights can be removed by taking the tie
rod, 1, out of the weight package, loosening the
bolt, 2, on the rear of the bracket, then removing
the cast block, 3, and lifting the weights from the
bracket. The last four weights on the right and left
hand side have the cast block installed through
the weight cut out. The remaining weights are
held in position by the tie rod.
