Power harrow

Attach PTO shaft guard chain in hole (1) on machine
side.
Intermediate PTO shaft 2
The machine is fitted with 2 intermediate PTO shafts 2
for driving the half harrows.
The PTO shafts are factory fitted and require no
adjustments.
The PTO shafts are factory fitted with a cam type cut-out
clutch. Check that cut-out clutches disengage during the
first periods of use:
- If the cam type cut-out clutches disengage too
frequently, the adjustment is too light. (See section:
Cam type cut-out clutch adjustment).
- If the cam type cut-out clutches do not disengage,the
adjustment is too heavy. (See section: Cam type cut-
out clutch adjustment).
Cam type cut-out clutch
Cam type cut-out clutches are based on the principle of
disengaging cams that release when an overload
occurs. When the cut-out clutch releases, it cuts-out
torque transmission to the machine.
When the cam type cut-out clutch releases:
- Disengage tractor PTO.
- Lift the machine off the ground.
- Engage the tractor PTO.
The cam type cut-out clutches re-engage
automatically.
To avoid serious accidents, the PTO drive
shaft guards must be properly in place and
fixed with the chains provided.
Immediately replace any worn or damaged
guard.
