3.2. Construction and operation
Fig. 2. General view of rear flail mower KBRP 200 mounted on a pantograph
Fig. 3. General view of the rear flail mower KBRP 200 mounted on a pantograph
The rear flail mower mounted on a pantograph consists of the suspension system (1) to which
the pantograph arm (2)is connected and which links the cutting unit with the suspension frame.
The miter gear (8), located on the outside of the carrier frame, is connected to the belt drive (3), forming
the carrier body. Installed inside of the carrier body is the flail-cutting shaft (7)and the coping shaft
(6). Power to the cutting shaft (7) is transferred from the ATS (4) to the miter gear (8)and then to the
belt drive (3). The belt drive transfers power directly to the flail shaft (7). The cutting unit (7) consists
of a thick-walled shaft on which the cutting blades are installed. The mounting of the cutting blades
works as a safeguard which protects the working elements from overloading or damage. During
operation when the resistance force of the obstacle is greater than the centrifugal force of the blade,
the blade tilts backwards and passes over the obstacle.
3.3. Equipment and spare parts
The mowers are sold with the following standard equipment:
❑warranty card,
❑operator's manual with catalogue of spare parts and declaration of conformity,
❑spare flail knives 2 pcs.,

4.10. Operation and construction of the hydraulic safety
The KBRP mowers have two mechanical types of protection (Fig. 10), protection (1) allows the
cutting unit to be lifted if an obstacle is encountered, protection (2) allows the cutting unit to tilt back
when an obstacle is encountered.
After encountering an obstacle the safety devices (1)and (2)cause the cutting unit to rotate on
the (3) and (4)pins which lifts the cutting unit. After passing the obstacle the mower automatically
returns to operating position.

5. OPERATING THE MOWER
5.1. Connecting the mower to the tractor
The mower should be connected to the tractor using the three point hitch as shown in Fig. 13.
It should be adjusted so that the sliding skid is parallel to the ground. After mounting the mower, its
position should be adjusted on level ground using the upper tie (1) and hangers (2) of the lower arms
of the tractor (Fig. 13).

WARNING!
When mounting the mower on the tractor position of the former should be
adjusted, so that PTO shaft (1) does not collide with any of the mower's parts as
provided in Fig. 11. Therefore adjust tractor’s 3-point linkage link right and left
tilting and displace cylinder’s eye (A) by unscrewing bolts and mounting them
back in position I, II or III (Fig. 12).
Fig. 11. Extreme most positions of mower when properly aligned
Fig. 12. Cylinder’s eye placement
The hangers (2) of the lower arms of the tractor should be placed on the pins (3) (Fig. 13) of
the suspension frame of the mower. Connect the hydraulic hoses to two sections of the tractor.
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 appendix or weigh the set, and
then drive on the scales only with front axis of the tractor (the mower must be in the transport position,
lifted up). If the weight of the front 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.

5.2. Preparing the mower for transport
Preparing the rear flail mower mounted on the tractor for transport - movement on roads - requires
the following:
❑mount the suspension frame on the lifting arms of the tractor,
❑lift the mower by means of hydraulic lift on the tractor's links until it is at about 50 cm / 1' 7.7''
above the ground (Fig. 14),
❑using the hydraulic actuator lift the cutting unit into a vertical position and then secure it with a pin
(S) (Fig. 15),
❑please drive very slowly on very uneven roads otherwise it can result in damage to elements of the
suspension or to the actuator.
WARNING!
Moving the mower from operating position to transport position and the way
around, should only take place on even and stable ground. Prior to making the
moves make sure whether there are no unauthorized persons exposed to any
hazard.

5.3. Connecting the articulated telescopic shaft (PTO)
The cover should be secured so that it does not spin by securing the holding chains to
a permanent part of the body of the tractor and the loop on the guard of the splined shaft of the mower
drive shaft.
WARNING!
If need be, shorten the PTO haft according to its operator’s manual given by the
shaft’s manufacturer (Fig. 16).
