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.
Beware of risks of cutting and crushing near the rotary hoe. When removing a
blockage, the hoe may move or rotate unexpectedly immediately after the blockage
has been cleared. Always shut down the loader engine and release he residual
pressure of the hydraulic system before going near the attachment.
6.1.1.
Direction of rotation
Check the rotating direction of the blades. The blades should
rotate clockwise when seen from the left side of the machine. The
hoe should rotate the same way as the wheels when reversing
with the loader. If the hoe rotates the wrong way, interchange the
hydraulic pressure hoses' places (when using conventional quick
couplings).
6.1.2.
Slope operation
Using the equipment on inclined terrain and slopes requires extra caution. Watch for holes, bumps, rocks
and other possible hidden obstacles. Uneven terrain could overturn the machine. Use low speed and do not
make sudden changes in speed or direction. Try to use the rotary hoe by driving straight up or down the hill,
not across, to avoid excessive side tilting. If the loader stops while driving up a steep slope, first stop the
attachment and then reverse slightly. Exercise extreme caution when moving near ditches or embankments
as the machine could suddenly turn over in case an edge caves in. On 200-series loaders, It is
recommended to use the optional wheel weights for the best stability on uneven terrain.
6.2.
Adjusting the cultivation depth
The working height adjustment works as intended when the
side skids are set parallel to the ground with the loader boom.
The height can be adjusted by setting the front of the skid to
one of the three possible options. One step equals about 50
mm change in the working depth.
If the hoe is equipped with the roller, the cultivation depth is
adjusted with the height and tilting of the loader boom. After
the tilting and height is set correctly, lift the hoe by using only
the boom lifting movement, without tilting the attachment. This
way the hoe can be lowered quickly to the correct operating
position and cultivation depth.
Keep the skids or the roller parallel to the ground for correct operation of the height
adjustment. Avoid pressing the attachment on the ground so hard that the front wheels of
the loader lift off the ground.

Inspections, maintenance and servicing
Continuous maintenance of the rotary hoe includes regular cleaning and lubrication of the equipment as well
as monitoring the condition of the blades. The drive chain must be checked and adjusted at least twice a
year or every 50 hours of use.
