3.3 Tractor Ballast
Before operating tractor and loader, add sufficient counterweight so a minimum of 25% of the
total weight is on the rear axle. Total weight includes weight of: tractor, loader, rated load in
bucket, and counterweight. Rated load is lift capacity at full height at 500mm forward of
bucket pivot point. (See Standard Equipment and Specifications). When determining
required counterweight bucket should be at maximum forward position (bucket pivot point at
the same height as boom pivot point on mast).
3.5 Tractor Hydraulics
The control valve is pre-set at factory and should not be adjusted. The loader uses two sets of cylinders; the
first set is used to operate the boom and the other set is used to operate the bucket.
3.4 Tractor Ballast and Tire Settings
To ensure tractor stability when operating a loader,
add wheel ballast, rear wheel weights, or 3-Pt
mounted Ballast Box with weight material. If 3-Pt
hitch ballast box is used, it should be carried as
low as possible at all times to maximize stability.
Effective counterbalance weight at the rear axle is
determined as follows (per ASABE EP562, March
2005)
A mass equivalent to the Lift Capacity to Max
Height (Specification V, refer to specifaction page
in the operationsection) should be placed in the
loader bucket.
Raise Loader until the bucket pivot pin is the same
distance from the ground as the Loader Boom pivot pin.
On a hard level surface, measure the loads for the front and rear axles. Add these two numbers together to
determine the Gross Vehicle reaction.
Add Wheel Ballast, Wheel Weights, or 3-Pt Mounted Ballast as needed to adjust the reaction at the Rear Axle
to a minimum of 25% of the Gross Vehicle Reaction.
For better stability, adjust tractor wheels to the
manufacturer’s recommendations. See Chart 1
below for recommeded settings for the MX5100
tractors.
