1. INTRODUCTION
The Lely Lotus 770 P is a pull-type rotary tedder-to ted mown fodder crops or
to wide spread crop swaths.
The working width of the Lely Lotus 770 P is 7.70 meter, and can be driven at
speeds up to 15 km/h. The wheels are positioned closely behind the tines to
follow ground contours accurately.
The Lely Lotus 770 P has 6 rotors. A rotor has 7 tine arms with a double spring
steel tine each. The special shaped tines pick up the crop and spread it with a
minimum loss. The rotors can pivot in relation to each other to follow field
indulations accurately.
The Lely Lotus 770 P is connected to the tractor hydraulics. The hydraulic
control makes sure the Lely Lotus 770 P moves quick and easily to the
transport position. The machine can be transported behind the tractor. The
transport width is 3 meter. The Lely Lotus 770 P has either a towing eye for an
upper tractor drawbar or a lower tractor drawbar.
Various optional extras are also available. Refer to Optional Extras Lely Lotus
770 P (page 1-2).

3.1 Connect the Lotus to the Tractor
1. Make sure the tractor is aligned with the Lotus.
2. If necessary, remove the parking jack from the storage support and
install it to the Lotus drawbar.
3. Turn the winding handle of the parking jack either clockwise or
counterclockwise to adjust the height of the Lotus until the towing eye
is at the same height as the tractor drawbar.
4. Install the Lotus towing eye to the tractor drawbar.
5. Install a correct linkage pin to the coupling system to connect the Lotus
to the tractor.
6. Turn the winding handle of the parking jack counterclockwise to move
the parking jack to the top position.
7. Turn the handle at rear of the parking jack counterclockwise to unlock
it.
8. Remove the parking jack from the Lotus drawbar and install it to the
storage support.
9. Turn the handle at the rear of the parking jack clockwise until it is locked.
10. Remove the wheel wedges and attach them to the support at the front
safety guard.
11. Make sure the primary PTO shaft telescopes smoothly.
The first time you connect the Lotus to each tractor, refer to the instructions
supplied with the PTO shaft and make sure the minimum and maximum
overlap of the two parts of the PTO shaft is correct.
Always connect the safety chain of the PTO shaft to a rigid part of the
tractor.
12. Make sure the Lotus PTO shaft telescopes smoothly.
13. Connect the Lotus PTO shaft to the tractor PTO shaft.
The maximum pressure of the tractor hydraulic system must not be more
than 21.0 MPa (210 bar).
14. Remove the dust caps from the two hydraulic hoses.
15. Connect the two hydraulic hoses to the double-acting hydraulic valve on
the tractor.

3.3 Move the Lotus from the Transport Position to the Working
Position
Make sure there are no persons in the area when you move the Lotus to
the headland position.
Make sure the safety guards are moved to the bottom position. Safety guards
in top position cause damage to the Lotus when moving from transport position
to the working position.

position (fig. 6, page 3-4).
2. Make sure all rotor wheel assemblies are set to the same position (page
4-4).
3. Operate the tractor hydraulics system to move the two outer rotor
segments upwards until they are completely upright (A) (fig. 7, page
3-5).
4. Make sure the locking hooks have disengaged.
5. Operate the tractor hydraulic system to lower the two outer rotor
segments to the ground (B) (fig. 7, page 3-5).
6. Set the hydraulic valve in the tractor to the floating position. The rotors
move downwards (C) (fig. 7, page 3-5).
7. Move the tines of the two center rotors to position A (page 4-1).
