Pull Height; Pull Tongue Height - Grizzly Field Boss Folding Wing Manual

9 Assembly Instructions

9:3 Pull Height

The Field Boss Folding Wing pull features
hydraulic pitch control and level lift for
precision operation. However the pull and
the pitch control mechanism must be set up
to work in the optimum position so that full
adjustment is available to the operator.
Too much tension will prohibit the ability of
the disc gangs to float over undulations, and
make it difficult to get a level finish.
When the plough is working at the required
depth, the optimum position of the pull is level,
or sloping slightly up towards the tractor.
IMPORTANT!
The initial setting up of your plough
behind a tractor is critical to its
correct performance.
