The work is influenced by the following factors:
1.
Driving speed
2.
Loader engine revolutions, loader model, output power of auxiliary hydraulics
3.
The type of soil being cultivated, its compactness and dampness
4.
Cultivation depth
The denser the soil is, the more the Rotary hoe requires hydraulic power from the loader. If the soil is loose,
slightly higher driving speed may be used, but on stiff and compact soil high loader engine engine rpm must
be used (high hydraulic oil output) and the driving speed must be relatively low. In some cases it may be
beneficial to use low operating depth to break the surface of the soil, and then till the soil more thoroughly with
a second run.
If the Rotary hoe stops rotating,
the driving speed has been too high or,
the hoe has hit a rock.
If blades hit a rock, lift the hoe slightly off the ground to avoid wearing or damaging the blades. If an obstacle
on the ground cannot be removed, try to go around it, as the Rotary hoe should not be used to chop obstacles
on the ground.

Avoiding and clearing blockages
WARNING
Beware of entanglement and crushing hazards especially
when removing blockages.
If a blockage is cleared without
first turning off the auxiliary hydraulics of the loader, the blade
shaft of the hoe will start immediately and potentially cause
severe injuries. Always stop the attachment by turning the
auxiliary hydraulics control lever to its neutral position before
leaving the driver’s seat, shut down the loader engine and
release the residual pressure of the hydraulic system.
Prevent blocking of the Rotary hoe by adjusting the driving speed according to the operating conditions. Keep
the equipment clean, so that material will not stick on it.
Normally, a blockage can be cleared by rotating the blade shaft to the opposite direction. Slightly lift the rotary
hoe up to ease cleaning of the attachment, if necessary. Avoid ejecting of material at high speed.
If necessary, clear the blockage manually using e.g. a broom, or broom handle, water spray, or other suitable
means that will not damage the blades or other parts of the Rotary hoe. Follow safe stopping procedure
before going near the attachment.
