Krone EasyCut 280 / 320 service schedule

1. Lower the mower to the ground, disengage the PTO, stop the tractor engine and take the key out. Stay in the cab until every disc and drum has stopped: they run on after the PTO is off.
2. Fold up the protective device and lock it with its spring cotter pin.
3. Check every blade. Turn a blunt blade over to use its other edge. Replace it when it reaches the wear mark (dimension a, 13 mm, in the handbook figure).
4. If any blade is missing or damaged, replace the whole set on that disc or drum so it stays balanced.
5. Check the retaining bolts at every blade change and after hitting an object. Replace any bolt under 14 mm at the thinnest point, as a full set per disc or drum.
6. Quick-fit models: check the leaf springs. They are worn out when the contact seam is worn through at any point. Replace with genuine Krone parts only.
7. Check the cutting discs and drums. Replace any that is bent (dimension A over 48 mm) or worn to under 3 mm of material.
8. Fitting a blade (screw-on): put it between the wear skid and the disc, push the bolt up from below and fit a new locknut from above. Tighten it to the torque in the handbook's Torques chapter.
9. Fitting a blade (quick-fit): push the blade key between the disc and leaf spring, press it down, slide the blade onto the bolt and let the key back up.
10. Clockwise and anticlockwise blades differ: the arrow on the blade must match the disc's direction of rotation.
11. Fold the protective device back down and lock it before starting.

Tools: Krone blade key (quick-fit models), Socket and torque wrench, Vernier caliper, Gloves, Spring cotter pin for the guard

1. Run the mower briefly, then stop the PTO and engine, take the key out and wait until the discs have stopped.
2. Rear mower: raise the cutterbar into transport position. Front mower: set the cutterbar level, with a spirit level across the disc hub (along the direction of travel) and along two discs.
3. Remove the oil level inspection screw on the cutterbar.
4. The oil should reach the hole. If not, top up with SAE 90.
5. Refit the screw and tighten it securely.

Tools: Spanner or Allen key for the level screw, Spirit level (front mowers), Funnel or oil pump, Rag

1. Stop the PTO and engine, take the key out and wait until the discs have stopped.
2. Look at the linings on the underside of the cutterbar and the wear skids under the discs for holes and heavy wear.
3. To replace a lining: grind open the old welds, take it off and deburr the face.
4. Fit the new lining. On top of the cutterbar weld short seams of about 30 mm in the marked areas; underneath weld it along its full length. Do not weld the edges.
5. Set the welding current and rod to suit the materials, and try a test weld first.

Tools: Welder (for replacement), Grinder, Wire brush

1. Stop the PTO and engine, take the key out and wait until the discs have stopped.
2. Check all nuts and bolts, especially on the cutterbar, guards and headstock.
3. Retighten to the handbook values. For 8.8 bolts: M8 25 Nm, M10 49 Nm, M12 85 Nm, M16 210 Nm.
4. Deviating torques listed for the cutting disc flange nut, the shear protection nut and the disc and drum bearing housings are 850, 300, 50 and 50 Nm; check the handbook table before using them.

Tools: Torque wrench, Socket set

1. Run the machine briefly, stop the PTO and engine, take the key out and wait until everything has stopped. Stand the mower level.
2. Rear main gearbox: remove the drain plug, catch the oil, refit the plug and fill through the filler.
3. Mower drive gearbox: remove the drain plug, catch the oil, refit it and fill through the filler until the oil reaches the check hole. Refit the check screw.
4. Front angular gearbox: it has no separate filler. Remove the inspection screw, drain the oil, then fill through the same hole until oil reaches it, and refit the screw.
5. Use SAE 90 only. If you use biodegradable oil, keep strictly to the intervals because it ages.
6. Dispose of the old oil properly.

Tools: Drain tray, Spanners, Funnel

1. Stop the PTO and engine, take the key out and wait until the discs have stopped.
2. Check the belts for cracks, fraying and glazing.
3. Slacken the lock nut on the tensioner and set the compression spring to dimension a = 205 mm.
4. Lock the nuts again.

Tools: Spanners, Steel rule

1. Stop the tractor, take the key out and wait until the discs have stopped.
2. Tighten the four nuts on the clutch so the springs are relieved.
3. Block the machine so the drive cannot turn.
4. Turn the friction clutch by hand until it slips.
5. Undo the four nuts again to their original position. Do not change the clutch setting.

Tools: Spanner for the four nuts, Chocks or a bar to block the machine

1. Clean the machine inside and out. Do not aim a pressure washer at bearings.

3. Pull the PTO shaft apart, grease the inner tubes and guard tube, the cross joints and the guard bearing rings.
4. Oil all joints.
5. Touch up paint and coat bare metal with rust preventer.
6. Check rollers, joints and tensioners move freely; replace worn parts.
7. Store it in a dry place, away from fertiliser and livestock buildings.
8. Make a list of parts needed so your dealer can get them before next season.

Tools: Pressure washer, Grease gun, Oil can, Rust preventer, Touch-up paint
