Choosing The Correct Gang Angle For Your Application; Changing Gang Angles - Grizzly Field Boss Folding Wing Manual

10 Operating Instructions
IMPORTANT!
The most common mistakes made
in operating tandem offset disc
ploughs are:
1 Wheels not touching the ground
when working.
2 Too much set (gang angle) for the
job.
3 Levelling adjustment springs are
too tight.
4 Failure to read and follow
instructions in the operator's
manual.
5 Operating at a speed greater
then the conditions and application
allow for.
10:4 Choosing the Correct
Gang Angle for your
Application
Most Grizzly offset disc ploughs do the
majority of their work on the middle settings.
It is important that all gangs are adjusted to
the same setting, otherwise forces within the
machine will be unbalanced.
IMPORTANT!
Take care and ensure that all
gangs are given the same setting
number and that all gangs are
fully aligned. Misalignment or
wrong settings will result is poor
ploughing performance.

ALWAYS USE AS LITTLE SET AS
POSSIBLE TO ACHIEVE YOUR REQUIRED
PLOUGHING DEPTH.
The reasons for this are:
1. Less power (kW (hp) is required to pull the
plough. At minimum settings there is less
soil carried on the face of each disc. This
means there is less soil movement and
significantly less draught than at greater
gang angle settings.
2. Minimum settings maximise your cutting
width.
3. Discs tend to last longer.
4. If obstacles are encountered, discs have a
better chance of rolling over them.
5. A greater percentage of straw is left on the
soil surface to protect the soil from wind
and water erosion.
6. A faster speed maybe achieved.

Changing Gang Angles

Gang angles on the plough can be altered to
suit varying soil and working conditions.
To alter gang angle follow these instructions:
To change the centre frame gangs:
1. Loosen the M24 pivot bolt and loosen the
M20 bolts on the slots on the outside of the
frame and completly remove the M20 bolts
located in the gang setting holes.
2. Raise the frame on the wheels using hy-
draulics and slide gangs using a crow bar
or similar.
3. Move the gang to the desired setting and
torque bolts to specified torque.
To change the wing gangs:
1. Loosen all M20 bolts located on slots and
completely remove the M20 bolt located in
the setting hole.
2. Raise the frame on the wheels using hy-
draulics and slide gangs using a crow bar
or similar.
3. Move the gang to the desired setting and
torque bolts to specified torque ensuring
the correct distance between wing gangs
and centre frame gangs. See Section 9:2.
