5 OPERATING THE ROTERRA
®
Make sure that nobody is near the machine at the moment
the PTO is engaged.
Do not allow anyone to come within a 50 m radius from
the machine during work.
Stop the tractor engine before leaving the tractor cab.
The depth control roller, rotor guard and soil deflectors
are essential protective components of the ROTERRA.
So: operate the machine only with these components duly
fitted.
If the ROTERRA power harrow is newly commissioned: first
carry out the check and maintenance duties which are
specified in “7.3 Intermittent Maintenance” before starting
the operation.
- Fold the soil deflectors down (fig. 12).
- Lower the ROTERRA power harrow and engage the PTO
shaft at the lowest possible engine rpm with the tines just
above the ground.
- Then increase the PTO rpm up to 540 or 1000 rpm
- Limit your forward speed to 7 km/h as a maximum. Higher
speeds may affect the quality of the work.
- When lifting the ROTERRA power harrow, disengage the
PTO at the moment when the tines are a few centi- meters
above the ground.
Never
allow rotation of the tine-holders
when the machine is in the lifted position.
Attention!
The ROTERRA power harrow’s gearbox will
develop a high temperature after working long hours under
demanding circumstances. Therefore, do not touch the gear-
box without protective gloves until it has cooled down
sufficiently.
- Keep the gearbox free from soil and any other form of
contamination so that optimal cooling by the ribs is
ensured.
