The brushcutter gearbox is a replacement component designed for grass trimmers, chainsaws, and lawn mowers. Built from high-quality aluminium alloy and steel, it resists rust and corrosion whilst delivering stable performance in demanding conditions.
This 26mm inner diameter gearbox features a 7-tooth round spline configuration, making it suitable for most standard brushcutter models. Installation is straightforward—simply disconnect the old unit and secure the new one in place using the existing mounting points.
The gearbox is engineered for durability in gardens, agricultural settings, animal husbandry operations, and forestry work. Its compact design ensures it fits within the standard trimmer head assembly without modification.
The unit arrives ready to install. Check your current gearbox specifications (inner diameter and spline type) before ordering to ensure correct fitment. If you need a different configuration—such as 28mm diameter or 9-tooth splines—we stock alternative sizes.
