The Beaver forestry prime mover transforms large vegetation into mulch, which can be groomed into topsoil for reforestation or property development.  This process can significantly increase the value and usefulness of the property.  The B425 is a powerful, yet compact, track-driven prime mover specifically designed for forestry reduction.  The mechanically driven PTO, with fluid coupling, maximizes machine performance while easing operator control.  The two speed hydrostatic drive offers infinitely variable second speed, up to 7 mph in high range.  All machine functions can be controlled without the operator removing his hands from the joystick.  The climate controlled cab, with its complement of gauges and electronic interface to all monitored engine points, maximizes operator comfort and awareness in the toughest conditions.  Large access doors make routine maintenance, like filter changes and fluid checks, simple.  The 425 horse-power Caterpillar engine offers the latest in diesel performance and reliability with on-board electronics that optimize efficiency and reduce downtime.  Even in the toughest conditions, the tractor remains sure-footed with its D-5 undercarriage.
