4.3 Technical description of the machine.
Machine base is a rigid frame. On the upper part of the frame, there is a 4-stroke
combustion engine, which drives the mowing disk through the V-belt. Mowing disk drive is
switched on by a tension pulley controlled from a lever on the handlebars.
On the mowing disk, there are three cutting blades of hardened steel, sharpened on both
sides and installed in a rotating position, which perfectly cut the mown sward. Upper disk
throws the cut sward aside. Support plate partly guides the machine, being a guarantee of an
even stubble height.
Side apron prevents grass spreading to sides and forms a neat swath.
Travel wheels are equipped with puncture-resistant tyres of solid rubber. Large
diameter of the wheels makes pushing of the machine easy and reduces operator’s labour.
On the tube handlebars, which can be adjusted with a swivel joint, there is a control bar
of the mowing disk drive clutch and a lever for engine speed adjustment. After tipping the
handlebars over the engine, the mower can be easily transported in the luggage compartment
of common passenger car.
