1. INTRODUCTION
The Lely Lotus 1250 Profi is a pull-type rotary tedder-to ted mown fodder
crops or to wide spread crop swaths.
The working width of the Lotus is 12.50 m (41.01 ft), and can be driven up to
15 km/h. The wheels are positioned closely behind the tines to follow ground
contours accurately.
The Lotus has 10 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
undulations accurately.
The Lotus is connected to the tractor hydraulics. The hydraulic control
makes sure the Lotus moves quick and easily to the transport position. The
machine can be transported behind the tractor. The transport width is 2.98 m
(9.77 ft).
A special headstock connects the tedder to the tractor. The headstock has
category II linkage pins. The pivot point of the headstock is positioned further
to the back in relation to traditional pull-type machines to provide a wide turn
circle. A wide turn circle makes the Lotus turn easy in tight bends.
An optional extra is available for the Lotus.

2. SAFETY
This chapter contains safety instructions you must obey when you use or do
maintenance on your Lely Lotus. It also explains the safety decals on the
Lely Lotus.
2.1 Signal words
Note the use of the signal words DANGER, WARNING and CAUTION. The
signal word for each message uses the following guidelines:
Danger: Indicates an imminently hazardous situation that,
if not avoided, will result in death or serious injury.
Warning: Indicates a potentially hazardous situation that, if not
avoided, could result in death, serious injury or product damage, and
includes hazards that are exposed when guards are removed.
Caution: Indicates a potentially hazardous situation that, if not avoided, may
result in minor or moderate injury or damage to the product or property.
Note: This shows extra information that may help the reader.
2.2 Safety instructions
• Use the Lotus only for the purpose for which it was designed.
• Follow all safety regulations, including those in this manual and
instructions or warnings indicated on the machine.
• Operate the Lotus in a safe manner.
• The Lotus must only be operated by authorised persons.
• Be alert and observe all safety precautions.
• Make sure all safety guards and protection devices are installed and
function correctly.
• Keep people, animals and objects away from moving parts.
• Stop the tractor engine, the Power Take-Off (PTO) and all moving parts
before you do operation adjustments and maintenance on the Lotus.
• Make sure no people are in the danger zone when the Lotus is in
operation. This is especially important when you work near or on areas
that are accessible to the public.
• Always use a tractor with a cab.
• Make sure there are no objects in the field that could be thrown up by the
Lotus before you operate the Lotus.
• Obey local legislation when you drive on a public road.
• Use flashing lights or other safety signs, when necessary.
• Do not remain on the Lotus during operation or transport.
• Only use genuine LELY parts.

Note:
Safety 2-1
T-H021.1301EN

• Depressurise the hydraulic system before you connect or disconnect
hydraulic hoses.
• Use protective clothing, safety shoes, gloves, safety glasses and ear
protectors, if necessary.
• Clean or replace the safety decals regularly so that they can be read at
all times.
2-2 Safety
T-H021.1301EN

2.3 Explanation of the safety decals
Caution: Read manual
Read the operator's manual carefully before
you operate the Lotus
Danger: Moving parts
Keep away from all moving parts unless they
are locked and cannot move.
Danger: Flying objects
Keep a safe distance from the Lotus when the
tractor engine is on.
Danger: Mowing or rotating parts
Read the operating instructions for the PTO
shaft. Always use the correct safety precautions
and protection when you operate the PTO
shaft.
Warning: Maximum operating speed
Never operate the Lotus at a PTO speed of
more than 540 rpm
Caution: Risk of damaged machine parts
Make sure to fold down the rear safety guards
before placing the Lotus in transport position.
Danger: Risk of being crushed
Do not sit on the Lotus.
2.4 Explanation of remaining decals
Note: Grease point
This indicates a grease point, read the operator
manual for maintenance instructions.

3. OPERATION
3.1 Hydraulic control panel
Read the tractor manual for the correct procedures to operate the tractor
hydraulics.
The operator switches the handle(s) or moves the joystick to operate the
Lotus. The following positions of the switches or joystick enable an action to
the hydraulic system:
•Floating (~)
The floating position opens the supply and return valves. The oil pressure is
not available in the system, but passive hydraulic movements are possible.
This position is used when working and disconnecting the machine.
•Neutral (N)
The neutral position closes the supply and return valves. The oil pressure is
available in the system, but no hydraulic movements are possible.
•Forwards/Reverse
The forward/reverse operations activates the hydraulic system. The
hydraulic operation of the Lotus depends on how the hydraulic hoses are
connected to the tractor:
• Oil flows to cylinders,
• Oil flow returns to tank.
1.Neutral (N) - 2. Forwards - 3. Reverse - 4. Floating
Figure 5. Panel hydraulic operation positions
Note:
Operation 3-1
T-H021.1301EN

The two hydraulic operations (forward/reverse) are depending on how the
connections are made to the tractor.
•Hydraulic system (I)
The blue marked hydraulic system (I) operates the following functions:
• the operation to fold the frame supports with rotors in or out between the
following position:
- the position after operating the hydraulic system II,
- headland position,
- working position.
• the operation floating during tedding.
•Hydraulic system (II)
The white marked hydraulic system (II) operates the following functions:
• the operation to lift the folded frame until it is lifted out of the transport
support.
• the operation to lower the folded frame into the transport support
(transport position).

3.2 Connect the Lotus to the tractor
Procedure
1. Ensure the towing vehicle has sufficient capacity to tow the trailer.
Do not exceed the maximum hitch load
2. Make sure the tractor is aligned with the Lotus.
3. Reverse the tractor to the Lotus headstock.
4. Make sure the three-point hitch arms of the tractor are at an equal
height.
5. Fit the lower arms to the linkage pins (cat.ll) of the three-point hitch.
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.
6. Make sure the Lotus PTO shaft telescopes smoothly.
7. Lift the PTO shaft from the PTO support.
8. Connect the Lotus PTO shaft to the tractor PTO shaft.
9. Set the hydraulic system of the tractor in the floating position.
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.
The maximum pressure of the tractor hydraulic system must not be
more than 21.0 MPa (210 bar).
10. Remove the dust caps from the three hydraulic hoses.
11. Connect the white marked hydraulic hose (II) to a single-acting
hydraulic valve on the tractor.
12. Connect the two blue marked hydraulic hoses (I) to the double-acting
hydraulic valves on the tractor.
13. Connect the lighting electrical cable to the correct socket on the
tractor.
14. Make sure all the lights on the Lotus operate correctly.
15. Remove the wheel wedges (1) (Figure 8, page 3‑5) and attach
them to the support at the front safety guards.
16. Lift the tractor 3-points hitch slightly to release parking jacks from the
ground.
