The Wallenstein Log Grapple
Trailer is a heavy-duty 4 wheel
trailer for hauling logs or wood-
stock out of the woods or a
woodlot. A boom and a pivoting
grapple is mounted on the front of
the frame for loading the logs.
The controls are mounted on
the front of the frame behind the
front frame. All hydraulic power
is provided by a small gas engine
mounted on the front of the frame
or by a tractor.
Stabilizers are mounted to the
front corners of the frame and are
extended for loading to provide
extra stability.
