3.2. Design and working principle
3.2.1. Trailed 4 -rotary tedder
Overview of 4-rotary tedder is provided in
Fig. 3
. Carrying frame (
4
) with drawbar (
9
)
enables mounting of the tedder to the tractor’s hitch bar. Drive from tractor's spline shaft is
transmitted by PTO shaft (
10
) and intersectional gears onto rotors. Tedder comprises three drive
units: left and right and main one, onto which rotors comprising arms (
1
) and tines (
8
) are set.
Safety guards (
2
,
5, 7
) are mounted on linkage and lateral drive units. For transport the two outer
units with rotors are folded by hydraulics to vertical position and locked with a locking pawl (
3
).

Parts of SaMASZ rotary tedder (for: P4-471 C, P4 – 531 C)
1 – Rotor arm
2 – Left safety guard
3 – Lock
4 – Linkage
5 – Rear safety guard
6 – Plate with luminous and reflecting
elements
7 – Left safety guard
8 – Operating finger
9 – Tiller
10 – Driveshaft
11 – Tiller support
12 – Cylinder with angle adjustment mechanism
13 - Holder for a warning triangle for a slow driving vehicle
When transported, the machine is trailed behind the tractor on two middle rotor wheels. To
prevent tines on middle rotors from being damaged, cylinder (
12
), placed in between the tiller (
9
)
and main frame, retracts the tedder to vertical position. Such setting of the machine provides
sufficient distance between working units and the ground during transport. When driving on public
roads the tedder should be equipped with a plate with luminous and reflecting elements (
6
), and a
warning triangle for a slow driving vehicle mounted on the holder (
13
)
.
