Calculating Ballast—Tractors Without Hitch

Add enough weight to the rear axle to achieve the desired weight split. Then, to increase total weight per engine horsepower add equal amounts of weight to each axle. The chart below illustrates how weight splits between the front and rear axles are affected as weight is added to the rear axle only.

ADD	9360R	9410R	9460R	9510R	9560R
1000 lb	58/42%	58/42%	58/42%	57/43%	57/43%
2000 lb	56/44%	57/43%	57/43%	56/44%	56/44%
3000 lb	55/45%	56/44%	56/44%	54/46%	54/46%
4000 lb	54/46%	54/46%	54/46%	53/47%	53/47%
5000 lb	—	53/47%	53/47%	52/48%	52/48%

* May not require additional ballast if power hop is not a concern. Up to 4000 lb may be required on rear axle to achieve desirable weight split if power hop is a concern.

Cast Weights Required for Ballast Recommendation
2130 lb — 1-165 lb plus 2-450 lb weights on each dual wheel
2800 lb — 1-1400 lb weight each inner wheel
3930 lb — 1-450 lb installed on each inside/inner and 1-165 lb plus 3-450 lb weights on each rear
7080 lb — 1 set of 20 rear frame weights and 1- 1400 lb installed on each rear inside/inner wheel and 1-165 lb plus 2-450 lb weights on each dual
