The T-4 is the four-way through-shaft slasher gearbox range for large platform applications rated to 150HP. Three gear ratio variants are available to suit different PTO speeds and output requirements. All T-4 models have three x 1-3/4" 20 spline input shaft positions, enabling through-shaft connection in multiple orientations. Freight is paid to any destination in Australia.

Available Variants

• B8671: 1:88.1 lower ratio reduction, suits 1000 RPM PTO, through-shaft 1:1 ratio
• B8674: 1:1.467 lower ratio increase, suits 540 RPM PTO, through-shaft 1:1.467 ratio
• B8676: 1:1.93 lower ratio increase, suits 540 RPM PTO, through-shaft 1:1.93 ratio

Selecting the Right T-4 Variant

The B8671 is the 1000 RPM PTO model. If your tractor runs a 1000 RPM PTO rather than the standard 540 RPM, the B8671 with its 1:88.1 reduction is the correct choice. The B8674 and B8676 both suit 540 RPM PTO tractors, with the B8674 at 1:1.467 for moderate blade speed and the B8676 at 1:1.93 for higher blade speed output.

Gearbox weights range from 85kg to 93kg depending on variant. Spare parts list available on request. Add EP140 gear oil before first use. Friction clutches and drive shafts are available to complete the driveline. Bareco through-shaft slasher gearboxes are built for the demands of large-scale Australian agricultural operations, backed by over 80 years of supply experience since 1944.
