Simba X-Press trailed disc cultivator service schedule

1. Park on firm level ground, lower the machine and stop the tractor.
2. Wipe the nipples clean and grease the DD roll bearings and the drawbar/axle cylinder. Simba marks 'one pump only' on the page.
3. Do not clean the roll or disc bearings with a high-pressure hose or direct water jet: the housings and ball bearings are not watertight.
4. Check the scrapers are set so they clear dirt from between the DD rings and do not touch the spacer, even under load.

Tools: Grease gun, Rags

1. Lower the machine and make it safe. Wear eye protection and gloves; disc edges are sharp.
2. Look over each disc blade for wear, chips and cracks, and for broken shear bolts at the arm.
3. Replace worn blades in pairs on the same frame so depth stays even, using the correct disc size for your frame.
4. The part numbers are from the 5.5 m disc frame page of the parts list; check them against your frame length.

Tools: Spanners, Torque wrench, Eye protection, Gloves

1. Lower the machine and make it safe.
2. Grease the wing pivots, drawbar pivots and disc pitch adjusters.
3. Check the hub caps, seals, pivot bolts and all tracking bolts for tightness.

Tools: Grease gun, Spanners

1. Lower and make the machine safe.
2. Grease each disc hub until fresh grease shows at the seals.
3. Grease the disc angle adjustment jacks and, on the DD light roll, the roll bearings.
4. If you use ordinary agricultural grease rather than lithium complex EP2, do the hubs every 50 hours instead.

Tools: Grease gun, Rags

1. Raise the disc frame onto the transport wheels and block it.
2. Check the stub axle is clean and the nut and outer bearing slide on easily.
3. Tighten the crown nut by hand spanner while turning the hub, until the bearing just drags. Some drag from the seal is normal. No torque figure is given.
4. Back the nut off to the next locking position, fit the retaining pin and check the hub turns freely with 0.1–0.2 mm play at the rim.
5. Brake and wheel hub work should be done by an authorised Simba dealer.

Tools: Hand spanner for the crown nut, Pin punch, Grease gun

1. Run the tractor at a low oil flow (tickover). Use the adjuster in the manifold block (valve 3).
2. Unscrew the adjuster until there is no resistance, unfold the wings and turn it clockwise to raise the pressure.
3. Start low and work up. Partly fold the wings, stop, then unfold again to check the gauge settles at the set pressure.
4. Check the hoses and the whole hydraulic system before every use.

Tools: Pressure gauge, Screwdriver

1. Check the wheel nuts at 270 N·m.
2. Check the tyre pressure, up to 3.5 bar (50 psi) maximum, and the tyre condition.
3. Test the brakes before first use and after the first laden journey. Check the road and parking brakes release and look for leaks of air or hydraulic fluid.
4. Leave brake and hub work to an authorised dealer.

Tools: Torque wrench, Tyre gauge

1. Wash the machine, keeping jets off bearings, and grease every point immediately afterwards.
2. Grease the DD light roll.
3. Check the discs and shear bolts for wear and order wearing parts before next season.
4. The storage page itself was not readable: check your handbook for any further steps.
