Un-matched continuous power:
Use of engine unsurpassed power rather than hydraulic or electric motors makes the power ratings usually supplied to other winches meaningless for the Bush Winch. With lots of power available the Bush Winch can easily handle a winch spool diametre a bit larger than the stud pattern on your vehicle wheel rims. This mean recovery speeds only a bit slower than the speed of the rotating wheel. Compare this to the very slow speeds you get from bull bar mounted winches.
Winching with wheels turning:
With the winch spool diametre and wheel diametres closely matched both work in unison to get you out onto firm ground with traction. This is often the difference between a clean one off vehicle recovery to a multiple slow jerky staged recoveries while the slow bull bar mounted winch catches up.
Axle level winching:
Winching from axle level is ideal as the vehicle tends to ride up and along the tight winch ropes. This is particularly useful when the vehicle is bellied out in sand or mud. Winching from bull bar level imposes huge strains and does little to break the suction/drag effect on the floor of the vehicle whereas the power and uplift of the Bush Winch does. Less strain means less wear and just as importantly better opportunities to actually find anchor points that can actually hold.
