TECHNICAL DESCRIPTION
The mower is a self-propelled machine with four-wheel drive, controlled by the transmitter (remote radio
controller) signal. Its unique wheel-steering technology ensures a high manoeuvrability both on level ground and
on slopes.
The basic part of the machine is formed by a square solid frame, which is connected with a sliding frame.
The middle part of the sliding frame carries all transmission parts such as the engine, the hydraulic pump, the
hydraulic motor and the control unit.
4 mowing blades are attached to the bottom part of the frame. An electromagnetic clutch is placed between the
main belt pulley and the engine. Circles formed by the rotation of blades do not overlap. The blades are fixed
and attached to the flanges by bolt. The cutting deck is open on two sides in order to facilitate the intake and
discharge of grass. These openings are covered by a chain curtain and by a rubber cover, which prevent the
throwing of undesirable objects. A steel bumper above the rubber cover on the outside of the mower marks the
safe distance from the blades.
Transmission is by chains and gears on all four wheels. The wheels are driven by two hydraulic motors through
V-belts. Wheels are steered by an electric motor.
The gel battery and the control unit are situated in the front part of the mower. The mower is controlled by a
multi-channel transmitter.
