BLADES AND QUICKLY REPLACEABLE ROTORS
The rotors and cutters are of high-quality. The cutters are made from special alloyed steel which is
tough and wear-resistant and therefore have long service life.
The cutters are manufactured for the current condition of drive machines (tractors) and conditions
under which these machines should operate, such as:
- working speed within the 0.6 to 1.0 m/s limits
- section length within the 0.05 to 0.10 m limits, up to a maximum of 0.15 m, ensuring high-quality
soil cultivation depending on the type and condition of the soil, and the humidity and use of
cultivated land.
- collision and vibration free operation, without overloading the tractor.
- cutter rotor rpm 200 min

Figure 8. Left and right cutter
The cutters must be properly adjusted. If this
is not the case, wear and tear quickly occurs and
reduces the work quality. Replace any cutters
extensively damaged during operation.
The rotary mower is shipped with properly
adjusted cutters on the rotor. However, if the
cutters have to be attached to the brackets on-site,
proceed as follows.
Determine which cutters are left and which
are right (see Fig. 8). Proceed to attaching them to
the corresponding brackets. Each section has 2 left
and 2 right cutters (Fig. 9, cutter arrangement on
rotor brackets).
DANGER: Cutter replacement is a
dangerous operation,
exercise caution.
CAUTION: In order not to
damage or break the cutters,
limit the tractor speed to 6 to 8
kmph. DANGER: During operation, the
cutters are also picking up stones and
other foreign objects; therefore, remove
children and animals from the work
area.
