Cutting defects
After work, if cut doesn’t result uniform and clean, follow next instructions:
• Check knife conditions.
In case of worn knives, you need to replace them (see chapter on maintenance).
• Check that cutting height adjustment has been done correctly.
It is possible that the cutting height adjustment by spacers has not been done in the same way for
the four wheels. Or it is possible that the versions equipped with rear roller, after the adjustment,
the machine and its knives have not been displayed parallel to ground.
After work, if cut doesn’t result clean the operator must stop the machine and check belt condi-
tion after removing the cover that protects them. In fact, there is a possibility of belt sliding, not
letting the knives cut with adequate power. Belt sliding occurs when lack of tension itself (belt
going too slow) or belt wear (see chapter on maintenance).
-If belts give signs of deterioration (even of small entity), immediate replacement is required.
-If belts are slow, immediate tensioning is required.
If after work the cut doesn’t present clean, it is possible that the machine’s going speed is not
opportunely adequate to the number of turns the rotor does, and therefore to the cutting speed of
the knives. Often happens that speed of the machine doesn’t give enough time to the knives for a
correct cutting.
In the case tall grass is being cut and ground speed is too high, it
is possible that grass accumulates between the frame and the
knives, taking to decrease efficiency in the cutting itself (see
Cutting Tips).
