The Q-2B (part number B86667) is the 75HP slasher gearbox with an integral output hub, eliminating the need for a separate stub shaft coupler between the gearbox and the blade disc. This is the integral hub variant in the 75HP range, sitting alongside the Q-2 (1:1.47 ratio) and Q-2A (1:1.93 ratio) which use a conventional output shaft arrangement. Freight is paid to any destination in Australia.

When the Q-2B Is the Right Choice

The integral hub design is specified on slasher platforms that are engineered to mount the blade disc directly onto the gearbox output hub rather than through a separate stub shaft arrangement. If your existing gearbox used a separate coupler, the Q-2A B6667 is the likely replacement. If your machine had an integral hub style from the factory, the Q-2B is the correct fit.
