 Rotational suspended disc mower is designed for mowing the following: common grass,
medick, etc on meadows and on stone free fields as well as forming swath out of these. Meadow
being mowed should be even, previously prepared by rolling. With advantage of high grass the
first and the second row should be cut at height of 6 - 7 cm, while with great share of lower
grass – at 5 cm. Therefore, the final row should be cut a little bit higher so 7 - 8 cm from the
ground.
 Trailed mower with swath conditioner/rollers is designed for mowing the following: common
grass, medick, etc on meadows and on stone free fields as well as forming swath out of these.
As a result of shifting the consequent forage layers due to operating flails/roller grass stalks are
being broken and/or crushed as well as are loosing wax layer. It makes grass drying process
simpler and faster by approx. 30 - 40%. Rollers are particularly recommended for mowing
papilionaceous grasses such as medick.
 Meadow being mowed should be even, previously prepared by rolling and other processing.
NOTE: Mow very rare grass with zero angle inclination.

Fig. 2b. Design of the trailed disc mower with swath conditioner
Fig. 2c. Design of the trailed disc mower with swath rollers
Hitch (14) is designed to mount the mower on a tractor. Drive onto cutterbar (4) is
transmitted from the tractor's rpm through PTO shaft onto intersecting axis gear (19), drive shaft
located on tiller (13), wide-angle PTO shaft (6) onto intersecting axis gear (20), cutterbar drive shaft
(5) and intersecting axis gear (7). Cutterbar has discs mounted with two rotary knives each. Extreme
most discs have additionally mounted swath guiding drums. Moreover drive from tractor's rpm
through intersecting axis gear (20), drive shaft (10) and belt gear (9) is transmitted onto swath
conditioner (3a) or rollers (3b). Cutterbar is mounted on linkage (1). Protective guard (16) is
mounted over the cutterbar. Maneuvering with the mower when driving is possible owing to two
hydraulic cylinders (12) which connect tiller to mower's linkage.
