Rotary tedder P4 – 471 and P4 – 531 Operator’s manual Rotary tedder P6 – 651 and P6 – 771 In order to prepare the machine for operation, perform the following: carefully (either manually or by means of loader) lower vertically positioned extreme most rotors, unlock pawls and eject cylinders, remount previously dismounted pin A (Fig.
Rotary tedder P4 – 471 and P4 – 531 Operator’s manual Rotary tedder P6 – 651 and P6 – 771 In order to perform this, the tractor should be weighed and then driven onto the scales with the tractor's front axis only (tedder must be in transport position, so lifted upwards). If the pressure on the front axis is at least 20% of the whole set’s pressure, it means the set is stable.

When driving on public roads the machine overall width should not be greater than 3 m. Since the SaMASZ tedder operating height of drive wheels can be is adjustable, change of this setting may lead to alternation of the machine transport width when folded. Therefore, the tedder transport width should be controlled prior to driving onto public roads and if needed wheels 1 setting should be changed (Fig.
Rotary tedder P4 – 471 and P4 – 531 Operator’s manual Rotary tedder P6 – 651 and P6 – 771 CAUTION: Use the machines with PTO shafts designed to drive them. Before the work begins, check the safety guards (in tractor, tedder and PTO shaft), if they are placed correctly and are not damaged.
Fig. 15.Unlatching the lock by means of a cord SaMASZ tedders are equipped with repellent mechanism for mobile tedder arms. Thanks to it, arms can be folded with no need of leaving the tractor cabin. It may however be limited by the slope, on which the machine is being folded.
