3.2. Design and working principle
3.2.1. 4- rotary tedder
Overview of 4- rotary tedder is provided in Fig. 3. 3-point linkage frame (1) with catch (2)
enables connecting tedder to the tractor 3-point linkage suspension. Drive with tractor PTO is
transmitted by intersectional gears onto rotors. The tedder comprises of three drive units: left and
right (4and 5) as well as main one (3), onto which rotors are set with arms (6) and fingers (7).
Safety guards (8) are mounted on the frame and lateral drive units. For transport the two lateral
units with rotors are folded by hydraulics to vertical position and locked with a locking pawl (9).

The tedder has been equipped with ground following mechanism (10) enabling for following
the ground unevenness by the machine with use of 3-point linkage suspension stiff connector.
The tedder may be equipped with (optional) ground following wheel (14). Chain for operating
position adjustment (12) is used for operation on very uneven ground to be used instead of the stiff
connector. Chain (13) is used when adaptation range of the mechanism (10) is not sufficient.
When driving on public roads the tedder should be equipped with a plate with luminous and
reflecting elements (11), and a warning triangle for a slow driving vehicle.

4. SAFETY PRECAUTIONS
The following precautions are for your safety. They must be read carefully
and followed by every person who operates or maintains the machine. Failure to follow these
safety precautions could result in serious injury or death to the operator, maintenance person or
bystanders and property damage to the machine and surrounding property.
Safety Signal Words
This manual and the safety labels attached to this equipment utilize signal words that signify
safety hazards with different levels of severity. Below are the words used and the definitions for
these words:
 DANGER indicates a hazardous situation which, if not avoided, will result in death
or serious injury
 WARNING indicates a hazardous situation which, if not avoided, could result in
death or serious injury
 CAUTION indicates a hazardous situation which, if not avoided, could result in
minor or moderate injury
 NOTICE is used to address practices not related to physical injury
4.1. General safety rules and regulations
The following descriptions are for your safety: They must therefore be read
carefully and applied every time you use the machine.
 The machine has been designed for use by one single operator.
 When using, servicing, repairing, moving or storing the machine, the operator must wear safety
footwear, safety gloves plus ear protection and dusk mask if necessary.
 During use, the machine may give rise to dust, especially if the soil is dry. You are advised to
use a tractor with a cab fitted with filters in the ventilation system. Failing this, wear a dust
mask with filter to protect your respiratory tract.
 Front axis of the tractor should be weighted to keep the balance. If need be, use front wheel
weights.
 In order to keep steering conditions, impact on front axis should be at least 20% of the complete
tractor.
 Be extremely careful whenever using hydraulic lift lever or buttons. Any operation with
hydraulic lift lever should be done from operator’s seat; DO NOT move the lever from outside
of a tractor.
 In case of tractors equipped with EHR, operating with hydraulic lift is done by the buttons
mounted outside the tractor’s cabin. When operating be extremely careful.
 Locking pawl line and “field edge” mechanism line (in the case of the P4-420 tedder) should be
mounted with relevant tolerance in the tractor cabin
 When moving from work to transport position, remove the entire PTO shaft or at least one end
of the shaft from the tractor’s PTO so it cannot turn.
 When attaching the tedder to a tractor, the operator should wear protective gloves.
