FAQS

A tractor toolbox should be fixed to a purpose-designed bracket or a structurally suitable mounting point using secure, correctly sized fasteners. The installation must not rely on the ROPS unless the tractor manufacturer has approved it, and drilling or welding the protective structure should be avoided. After fitting, check that the box cannot move, open accidentally or interfere with controls, visibility or maintenance access. 
The best position is accessible from the ground, protected from mud and moving parts, and clear of the driver’s view, controls, lights and access steps. It should not create a snagging hazard or reduce ground clearance. A rear linkage-mounted weighted toolbox may be appropriate where both storage and counterbalance are required, while smaller boxes are often mounted on approved chassis or cab brackets. 
Choose a box large enough for the tools and parts routinely carried, but small enough to fit without obstructing the tractor or exceeding the mounting capacity. Account for the combined weight of the empty box, tools and any ballast. For linkage-mounted boxes, confirm the tractor’s rear-lift capacity and the amount of counterweight actually required for the front attachment in use. 
Yes, a purpose-built weighted tractor toolbox can combine secure storage with rear ballast. The ballast must be retained inside the box, the total weight must stay within the tractor and linkage limits, and the box should be positioned so it provides effective counterbalance without making steering light or reducing stability. A normal lightweight toolbox should not be filled with improvised ballast unless it is designed for that purpose.
