Gearboxes

Shop replacement gearboxes for slashers, spreaders, and a wide range of agricultural machinery. Our range covers direct-fit PTO-driven gearbox units suited to lifestyle blocks through to commercial farm operations — built to handle the tough conditions of Australian paddocks.

Why Replace Your Gearbox?

A worn or damaged gearbox reduces power transfer efficiency, increases wear on connected components, and can lead to costly downtime during critical seasons. Replacing with a quality unit restores full performance and extends the life of your machinery.
