How to select the right swath and what are the factors for our choice?
a) The working span of your mower – the width of mown swaths.
b) Fodder tedder weight – transportation of a fodder tedder carried by hydraulic arms.

What facilitates the swing of consoles during terrain copying and their tilting into their transportation position?
A swivel joint of the consoles and shaft connection by means of a hinge or double hinge.

What transfers the torque from the central case to the individual rotors?
Torque is transferred by a hexagonal shaft supported on ball bearings.

What prevents machine vibrations during work and riding away on the slope?
Amortization bars connecting the three-point hitch and the machine frame.

How many working arms are there on each rotor?
The rotors are equipped with six arms each of which with one raking double-finger.

What is the quality of working fingers and what is their material?
The working fingers are made from a material with plastic memory that guarantees long service life at high working loads on a rough terrain.

What prevents overloading of the machine during work?
An overload clutch is mounted on the connecting cardan shaft.

Is it possible to adjust the height of a working finger from the swath by means of the travelling wheels?
Each rotor can be adjusted, independently of the machine frame, with an adjusting crank.

How are your two-rotor delivery rakes tilted into their transport position?
Tilting into the transport position is made possible by two hydraulic cylinders controlled from the tractor driver’s seat.

How many working arms are there on a delivery rake rotor?
A delivery rake rotor has eight, ten or thirteen working arms that are fixed by means of locking pins and rings for easy mounting and dismounting.

How many double-fingers are there on each rotor arm?
Types SB-3621 and SB-3921 are equipped with 3 raking double-fingers, the others have 4 raking double-fingers.
