The T-4A is a 150HP through-shaft slasher gearbox in the T-series, available in two gear ratios. It shares the same through-shaft, heavy-duty configuration as the T-4 but in a lighter 70kg package with a narrower ratio selection, suited to large slasher platforms where the simpler 1:1 or 1:1.3 output suits the application. Freight is paid to any destination in Australia.

Available Variants

• B8669: 1:1 gear ratio
• B8674: 1:1.3 gear ratio

T-4A Versus T-4

The T-4 offers three gear ratio options including a 1000 RPM PTO variant and ratios up to 1:1.93. The T-4A is a more focused range offering 1:1 and 1:1.3, both for 540 RPM PTO applications. At 70kg, the T-4A is notably lighter than the T-4 range (85 to 93kg), which may be a factor on slasher platforms with a weight limit on the gearbox mounting position.

Three x 1-3/4" 20 spline input shafts. All models are 150HP rated. Specification drawing available on request. Spare parts available on application. Add EP140 gear oil before first use. Friction clutches and drive shafts to complete the driveline are available.
