Operating principle
9.1 Raking and forming of windrows
The rotor constitutes the main working element of the hay rake and it consists of a reduction
gearbox equipped with 11 arm housings to accommodate tine arms. Via PTO shaft the
torque is transferred from the tractor to main drive shaft located inside the main frame and
then to the rotor gearbox. Transmission of the torque to the gearbox causes swivel
movements of the rotor. Inside the rotor housing there are cam rollers connected to the
individual tine arm housings. During swivel motion of the rotor, the rollers run on the cam
track of special construction forcing their movement up and down as well as their pivoting
motion. This allows for the fluid alteration of the vertical and horizontal position of the
raking tines. In the raking phase the raking arms are lowered and the vertically set tines
come into contact with the crop dragging it sideways in a sweeping motion. The thrown
outwards crop stops on the crop deflector forming a uniform windrow. In the next phase the
arms are lifted, the tines pulled out of the crop and angled in which position they stay until
they reach the raking area again. This motion creates sufficient clearance not to drag the
crop back into the raking area. Combination of all these features makes the machine
thorough and efficient but gentle to the crop.

where the raking tines are directed perpendicularly to the ground.
