1. INTRODUCTION

The Lely Lotus 770 P is a pull-type rotary tedder-to ted mown fodder crops or
to wide spread crop swaths.

working width of the Lely Lotus 770 P is 7.70 meter, and can be driven at

The
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).

WARNING

WARNING

WARNING

WARNING

Note:

WARNING

Make sure no persons are near the Lotus when you engage the PTO.

Make sure no persons are within a 25 meter radius of the Lotus during
operation.

Always switch off the tractor engine before you leave the tractor cab.

Do

not operate the Lotus without safety guards or covers, or if the safety

guards or covers are damaged.

During the early stage of the process in particular, fast and airy tedding
twice a day at a low rotor speed is better than intensive tedding at a high
rotor speed.

1. Operate the tractor hydraulic system to lift the rotors to the headland
position.

2. Carefully engage the PTO at the lowest possible engine speed.

3. Slowly increase the speed of the PTO to 400-450 rpm (max. 540 rpm).

Do not drive the machine through the crop when the rotor is on the
ground and not rotating. This causes damage to the tines and tine arms.

4. Drive the tractor at a minimum speed of 15 km/h and make sure:

T-H001.1103EN

Note:

• The hydraulic rams telescope smoothly

• The PTO speed stays at the speed shown on the Lotus.

5. Set the tractor hydraulic system to the floating position to lower the rotors
to the ground.

6. If necessary:

• Adjust the tines (page 4-1).

• Adjust the rotor angle (page 4-2).

• Adjust the height of the rotor wheels (page 4-4).

7. The following tedding procedure is recommended:

1. Drive the tractor up and down to ted the center part of the field

(1). Keep a lane of approximately one working width free at the
sides of the field.

In case of windy weather conditions, drive the tractor up and down
against the wind.

2. Drive the tractor along the side of the field to ted sides (2).

Operation 3-9

3.6 Move the Lotus from the Working Position to the Headland Position

1. Operate the tractor hydraulic system to lift the rotors to the headland
position.

3.7 Stop Tedding

T-H001.1103EN

WARNING

WARNING

3-10 Operation

Always switch off the tractor engine before you leave the tractor cab.

1.

Stop the tractor.

2. Operate the tractor hydraulic system to lift the rotors to the headland
position.

3. Disengage the PTO.

Wait for all moving parts of the Lotus to stop.

4. Switch off the tractor engine.

4. TEST AND ADJUSTMENT

4.1 Adjust the Tines

1. Disengage the lock from the tine.

2. Move

the tine to the applicable position. The lock returns automatically.

Note:

Note:

T-H001.1103EN

Position A gives a large spread of the crop. Position B gives a small
spread of the crop.

If you want to ted the side of the field, set the tines of the rotor adjacent
to the side of the field to position B. This gives a small spread of the crop
at the side of the field and makes sure the crop stays on the field.

Figure 12. Adjust the Position of the Tines

Test and Adjustment 4-1

4.2 Adjust the Rotor Angle

CAUTION

Make sure the height adjustment of the tines is not too low. This results in an
excessive load and causes the tines to wear or break.

Make sure:

1.

1. The Lotus is connected to the tractor (page 3-1).

2. The Lotus is in the working position (page 3-4).

3. The hydraulic system is set to the floating position.

2. Remove the parking jack from the storage support (fig. 5, page 3-2).

3. Install the parking jack underneath the frame of the transport wheel.

4. Turn the winding handle of the parking clockwise to lift transport wheel
from the ground.

5. On both sides:

1. Remove the five bolts from the transport wheel assembly.

2. Adjust the transport wheel assembly to the applicable height.

3. Install the five bolts.

6. Make sure the tines slightly touch the ground and the crop is picked
correctly.

7. Make sure the tines touch the ground over a distance of approximately
25 cm.

8. If necessary:

• Adjust the height of the rotor wheels (page 4-4).

4.3 Adjust the Height of the Rotor Wheels

CAUTION

Note:

Make sure the height adjustment of the tines is not too low. This results in an
excessive load and causes the tines to wear or break.

Move the Lotus to the headland position (page 3-10).

1.

2. Switch off the tractor engine.

3. Make sure the rotors can not move downwards.

4. Remove the locking pin from the wheel assembly.

5. Adjust the wheel assembly to the applicable hole.

The top hole gives a higher working height. The bottom hole gives a lower
working height. A lower position of the wheel assembly is recommended
when working in light and short crops or windy conditions.

6. Install the locking pin in the wheel assembly.

7. If necessary:

• Adjust the rotor angle (page 4-2).
