Changing Direction and Reversing the Tiller
When turning or backing off, the tiller should be lifted up and the PTO should be shut off. Do not turn
during cultivating, or it could cause damage to the blades and possible damage to the tiller.
Maintenance
Proper maintenance is important for keeping the tiller in good, working condition and to maintain a
long service life.
Maintaining the Tiller
1. Provide maintenance after every 10 hours of operation.
2. Check and tighten all connecting nuts and bolts. Check whether the oil draining thread plug is
loosening.
3. Check if there are missing or defective plug pins. Split pins in all positions and supplement them
or replace with new ones, if necessary. Split pins should only be replaced with new split pins.
4. Check the gear oil level in the gear box. The gear oil should be filled to the level just overflowing
the inspection hole. Tighten the oil inspection plug.
5. Check whether there are missing or defects of blades, or if loosened bolts need tightening.
Supplement and tighten if necessary.
6. Check for an oil leak. Replace the oil sealing and paper gasket, if necessary.
First-Class Maintenance (after one working season)
1. Follow maintenance instructions.
2. Change the gear oil.
3. After each use, clean the debris from the tiller tines. Inspect for any damaged or worn parts and
replace before the next use.
4. Check whether the blade is worn excessively. Replace it when necessary.
5. Check each bearing clearance and bevel gear clearance, and adjust when necessary (as
above).
Second-Class Maintenance (after one year’s cultivation)
1. Clean any oil, dirt, or grease off the tiller.
2. Drain the gear oil and dissemble to check. Pay special attention to the wearing of the idler gear
bearing. The components need to be cleaned when assembling. New gearing oil should be filled
to the specified level after assembling.
3. Disassemble and wash the blade arbor bearing and its chocks, replace the oil sealing, and fill
grease when assembling.
4. Disassemble and wash the universal assembly joint. Clean and wash the needle of the cross
shaft, replace it when worn.
5. Disassemble all blades for inspection. They must be replaced when worn or cracked.
6. Check if there is a crack on the blade holder of the blade arbor, if the hexagonal hole is
damaged, or if the welding joint between blade holder and blade arbor pipe is cracked. Remove
the damaged blade holder and weld a new blade holder when necessary.
7. Repair the machine case, drag the tiller, and recover to the original condition. If it’s impossible to
repair, replace it with a new one. If the tiller will be idle for long periods of time, the universal
assembly joint should be disassembled and stored indoors. The tiller should be padded with the
blade away from the ground. Machine oil should be painted on the blade to prevent rusting. If
