3.2. Design and working principle
Overview of rotary tedder is provided in
Fig. 3
. 3-point linkage frame (
1
) with catch (
2
)
enables attachment of the tedder to the tractor's 3-point linkage. Drive from tractor’s rpm is
transmitted through intersecting axis gears onto rotors. On the tedder there are three (five for P6 -
651 and P6 - 771) drive units: left and right (
3
and
4
) as well as the main one, onto which rotors are
mounted with arms (
5
) and fingers (
6
). Safety guards (
7
) are mounted on the frame and side drive
units. For transport the two side units with rotors are folded by means of hydraulics to vertical
position and blocked with a lock (
8
).
