Kuhn Multi-Leader NSH semi-mounted reversible plough service schedule

1. Lower the plough to the ground and make sure it cannot move. Stop the tractor and take the key out.
2. Look at every share tip, point, landside and mouldboard. Replace shares when the tip has worn so the plough no longer pulls in.
3. Fit new parts with the bolts tightened to the torque in the handbook table.
4. On the furrow-width, vertical and offset settings, recheck the first body after changing parts.

Tools: Socket set and torque wrench, Gore tool or hammer, Eye protection, Gloves

1. Park the plough on firm ground, switch the tractor engine off, take the key out, wait for everything to stop and apply the parking brake.
2. Clean the nipples and grease the front pivot pin.
3. Grease the shafts between the headstock and the frame.
4. Grease the wheel, the trailed implement arm (if fitted) and the disc coulters (if fitted).
5. Grease everything again before storing the plough at the end of the season.

Tools: Grease gun, Rags

1. Park the plough, stop the tractor and take the key out.
2. Check every nut and bolt, especially on the bodies, the headstock and the wheel. Use the torque table in your handbook (standard ISO 898-1 values).
3. Check the tyre pressure on the depth wheel to your handbook.
4. Check the axle nut is tight (40 daNm).

Tools: Torque wrench, Spanner set, Tyre gauge

1. Set the plough bodies in work at 20 in width. Connect the circuit hose to a tractor spool valve.
2. Open the valve by no more than two turns. Run the tractor spool until the gauge shows the pressure for your soil: 90 bar (light, stony ground) up to 150 bar (clay).
3. Close the valve, remove the two pins from the beam and disconnect the hose.
4. If the pressure drops while ploughing or a body skips, there is air in the circuit. Bleed it by raising the plough off the ground and cycling the circuit several times, letting the body drop as far as possible, then inflate again after bleeding.
5. Never take the pins out of the beam while the circuit is under pressure and make sure nobody is near the swing area.

Tools: Pressure gauge on the plough, Spanners, Rags

1. Lower the plough and release the pressure.
2. Check the turnover ram, lift ram and Non-Stop cylinders and every hose and fitting for leaks and chafing.
3. Replace hoses at 5 years and the accumulator at 10 years. Apply your national rules for pressurised equipment.

Tools: Spanners, Rags, Card (for finding leaks)

1. Clean the plough thoroughly with a water hose. If you use a high-pressure cleaner, keep it off the cylinder and hose seals.
2. Check all tools and their fixings.
3. Coat the working parts with a mix of grease and diesel to stop rust.
4. Grease the cylinder rods that are exposed, then push the rods fully in to protect them from damp and dust. Touch up paint.
5. Grease the machine, fit the protective caps on the hydraulic couplings and store under cover in a dry place.
6. At the start of the season: re-read the handbook, check the plough is greased, wipe grease off cylinder rods, check tyre pressure, nuts and bolts and hoses.

Tools: Water hose, Grease gun, Paint for touch-ups
