Lely Lotus 460 Stabilo / Lotus 520 Stabilo service schedule

1. Lower the tedder to the ground, disengage the PTO, stop the tractor engine, take the key out and apply the parking brake. Wait until the rotors have stopped.
2. Grease the nipples on the PTO shaft cross assemblies, the protection tubes and the K33 slip clutch.
3. Pull the shaft apart and grease the profiled tubes.
4. Grease the cross assemblies of the double universal joints between the rotors.
5. Check the PTO shaft slides in and out smoothly and the guards are complete and chained.

Tools: Grease gun, Rags

1. Lower the tedder to the ground, disengage the PTO, stop the tractor engine, take the key out and apply the parking brake. Wait until the rotors have stopped.
2. Wipe each gearbox nipple clean.
3. Pump grease into the gearbox while turning the rotors round a little at a time by hand, so the grease reaches every gear.
4. Check each gearbox for grease leaking out. Leaking grease means a seal or gasket needs attention.

Tools: Grease gun, Rags

1. Unfold the tedder into work position on the ground, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
2. Grease the pivots of the side (lateral) rotors.
3. Grease the pivots of the Stabilo steering device.
4. Grease or oil all the other pivot points.

Tools: Grease gun, Oil can

1. Unfold the tedder into work position on the ground, disengage the PTO, stop the tractor engine, take the key out and apply the parking brake. Wait until the rotors have stopped.
2. Wear gloves. Check every tine for cracks, bends and wear, and every tine arm for bends and looseness.
3. Replace broken or bent tines with the right hand for that rotor's direction.
4. Tighten loose tine and tine arm bolts to the torque for their size in the handbook's table (for example M12 85 Nm). The manual gives no separate tine bolt figure.
5. Clean rust and crop off the tines.

Tools: Spanners, Torque wrench, Gloves

1. Lower the tedder in work position on hard, level ground, disengage the PTO, stop the tractor engine and take the key out.
2. Grease every point in the 8-hour and 40-hour tasks, plus the spring-loaded locking pins of the PTO shaft yoke.
3. Check the PTO shaft telescopes smoothly. A damaged shaft wears both the tedder and the tractor.
4. Look the machine over for damage.
5. Check the tyre pressures against the figure in your handbook (it shows 2.75 bar and 1.5 bar).
6. Check all nuts and bolts and tighten loose ones to the table: M8 25 Nm, M10 50 Nm, M12 85 Nm, M14 135 Nm, M16 215 Nm, M20 410 Nm.
7. Rotor sag check: with the tedder on level ground, raise the centre wheels 60 mm. The tedder should be level and the stop bolts should just touch their stops.
8. Check all safety decals are there and readable.

Tools: Grease gun, Tyre pressure gauge, Torque wrench, Tape measure, Jack

1. Lower the tedder, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
2. Clean the machine thoroughly.
3. Check the tines and tine arms (see the tine task).
4. Coat the machine, and the tines in particular, with anti-corrosion agent.
5. For long storage, coat the ram piston rod too, and wipe it off before use. If it hardens on the rod it can damage the ram seal.
6. Park it on hard, level ground. Lely recommends storing it folded out.
