A front loader moves the tractor’s centre of gravity forward. Without the correct rear ballast, the rear axle can become too light, reducing traction and steering control. The right counterweight depends on tractor model, loader, attachment, load, tyre setup and whether ballast is carried on the linkage or rear wheels. There is no safe universal “one tonne for every loader” rule.
Use the loader and tractor manuals together. Confirm the required ballast for the specific loader configuration, then check the tractor’s front and rear axle limits, tyre capacity and total permissible mass. An attachment also changes the load centre: a bucket full of wet material imposes a different load than empty forks positioned close to the carriage.
A real example shows why model-specific figures matter. John Deere’s H260 loader specification for a 6430 Premium lists a 1,000kg rear ballast option on the three-point hitch or 1,300kg on the rear axle only. Those figures apply to that exact setup; they should not be transferred to another tractor or loader. Follow the current manual and dealer guidance for the machine in front of you.
Operate with the load low while travelling, turn slowly, avoid slopes and uneven ground, and do not carry a raised load across the yard. HSA guidance says counterweights help stability and should be used when required. Never exceed the loader’s rated capacity, and do not rely on ballast to correct an overloaded or mechanically unsuitable tractor.
When inspecting a used loader tractor, check rear-wheel contact, steering effort, front axle play, tyre wear and evidence of loader fatigue. If the required ballast is missing, include its proper cost and installation in the buying decision before using the loader.
