6.1.3. Recommended Rear Tractor Ballast
CAUTION: To help prevent rollover, use recommended rear tractor ballast and widest wheel
settings to maximize stability. See your tractor Operator Manual and information on the following
ballast.
Rear tractor ballast is required after installation of loader on the tractor. Following is recommended ways to
ballast your tractor.
Install factory rear wheel weights to tractor.
Install a calcium solution in rear tractor tires.
Install a weight box to tractor 3-point see optional attachments section in this manual.
Install some type of 3-point attachment to tractor.
Install a backhoe to the tractor.
NOTE: You may need to use one or a combination of the above rear ballast methods depending on your
tractor and loader application.
To check if your tractor is properly ballasted you should conduct the following rear axle weight check.
With 1800# installed in 72” bucket, 1900# in 78” bucket or 2100# in 84” bucket.
With operator in tractor.
With bucket/loader pivot pin positioned as shown in fig. 1.
With ballast installed on rear of tractor.
Weigh total vehicle weight.
Weigh rear axle of tractor. Tractor rear axle must weigh a minimum of 25% of total weight of unit.
Example: If total weight of unit = 10,000#, rear axle weight needs to be 2,500# or greater.
With weight above installed in
your Bucket with Bucket Pivot
level with Boom Pivot
Bucket Pivot
Boom Pivot
Rear Axle should weigh a minimum of 25% of total tractor weight
CAUTION: To allow proper steering of the tractor always remove 3-point weight from tractor when
the loader is parked from the tractor. Never operate the unit with the loader parked and the
backhoe installed. Failure to follow these instructions could cause loss of tractor steering
causing personal injury and damage to property.
Front tractor weights must only be used when the loader is parked. Weights must be removed before remounting
loader or serious damage will occur to loader or tractor front axle due to excessive weight. The use of adequate
rear counterweight to counterbalance for maximum loader capacity is required for safe loader operation. Weight
added to the rear of the tractor provides better traction and easier, more efficient loader operation.
IMPORTANT: Do not exceed the maximum load capacity of the tires on your tractor. See Tire and Wheel
Specifications in tractor Operator Manual for more information.
NOTE: Rear tractor ballast must be added equally to tractor to allow loader bucket to set parallel to the
ground. After installation, check that the tire pressure is equal and the center of rear axle off of ground is
equal from right to left side of tractor. This inspection must be completed on a hard level surface.
