3.2. Design and working principle
The front-rear flail mower (Fig. 2) is constructed of the suspension frame (1), which is used to
connect the mower to the three point hitch, at the front and at the rear of the tractor (RIO – at the
rear of the tractor).
Drive from the vehicle PTO shaft is transmitted through jointed telescopic shaft (2) and
intersection angle gear (6) onto driving shaft (3), and then the belt gear (5) is driven by the flail
shaft (12), on which flail knives (13) are mounted.
Clevis feet of the flail blades (cutting) functions as a safeguard of the operating elements from
overloading and damage. During operation if the value of resistance force of the obstacle exceeds
the value of the centrifugal force of the blade, the blades tilts back and avoids the obstacle.
The mowing height is regulated by adjusting the position of the copying shaft (11).
Steel skids (14) protect the machine when passing through an obstacle.
In VINO flail mower, cleaning plate (9) helps remove winding grass and dirt on the copying
shaft (11). Counter knives (10) keep the comminuted material for re-mulching. Please adjust the
position of counter knives according to mowing height – do not set below the ground level.

5. USE OF MOWER
5.1. Mounting mower on tractor
The mower should be connected to the tractor using the three point hitch as illustrated
in Fig. 9. The upper connector (1) and the hangers (3) of the lower ties of the tractor should be
placed on the bolts (2) of the suspension frame of the mower
Machine should be adjusted in such a way that the sliding skid is perpendicular to the ground.
After connecting the mower it should be adjusted on level ground using the upper connector (1) and
the hangers (3) of the lower ties of the tractor (Fig. 9).
After connecting the mower to the tractor check the lengthwise balance and steering ability of
the tractor-mower unit. To do this, calculate to formulas given in the chapter 8 or weigh the set, and
then drive on the scales only with front/rear axis of the tractor (the mower must be in the transport
position, lifted up). If the weight of the front/rear axle of the tractor is at least 20% of the entire
weight of the unit then steering ability has been preserved. If this is not the case the front axle
should be additionally weighed down. The same procedure should be followed when connecting the
mower to the front/rear of the tractor.
