Chapter ⅠMain technical specifications These series rotary tiller, are driven by the power-take-off of tractor. It is a kind of excellent equipment and secondary tillage. It can match with 18.4-44.1 kw (25-60HP) wheel-tractor, working on unplowed and plowed field. It has the characteristics of cold smaller on dry tillage, clay mashed and enough slurry on paddy field, surface soil smooth, good coverage with weed and stubble, working depth uniform, efficiency high.

Joint manner Standard three-point linkage Overall dimensions 1450×800×700 1550×800×700 1700×800×700 2000×800×700 (L×W×H)(mm) Total quality (kg) Quality of gear oil Gearbox≈2.5 side transmission box≈4 (kg) Working in dry paddy fields and caked rice fields, rotating tillage and cutting off green manure at 100kg/ha, shallow tillage in saline-alkaline land below average, tillage in Application scope vegetable garden, land reclaiming, etc.
Chapter Ⅱ Brief introduction on the structure and their adjustment These catena rotary tillers are tillage equipment by means of the compound motion both of the rotation of the tractor going forward. It consists of universal coupling, headstock, gearbox, side chain box (gearbox) are transmission sets. Blade and blade shaft are working parts. Headstock, the cover and trailing bar are sets assistant.
Fig.1 The side sketch of rotary tiller 2.1 Universal coupling assy The universal coupling consists of universal joint head, universal joint head for male shaft, the universal joint head for female shaft and joint cross. There are rings on the both ends of joint cross to avoid the movement of joint cross, and there is also a grease hole on the joint cross and the needle bearing can be well lubricated if you inject grease into it frequently.
just move the pinion forward when you do it. Adjustment of the bearing axial clearance on the second shaft when the axial displacement was occurred very distinctly on the second shaft, you must adjust it in time as following steps: First, loosen washer and screw down the locknut, then adjusts the displacement of the bearing on the second shaft until there was no distinct axial movement and easy to rotate the shaft.
Chapter Ⅲ Methods of operating 3.1 Installation of headstock with the main body Before being put in the container, the equipment is parted with the main body. The users refer to fig.2 simply to fix it on the main body with the bolts in the affix pouch.
3.4 Adjustment before working 1. Adjustment of horizontal level Put it down to make the blade tips near to ground, observe that the height between the right and left blade tips and the ground is same or not. If not, it is necessary that the right linkage arm of tractor be adjusted to level off the blade shaft, which ensures the uniformity of working depth.
the empty time in turn land will be longer, the efficiency be less, the repeat times of idle motion be more, tne mud depth be longer. The flat tillage in the medium and small fields refer to in land plowing.

depth at the same time. 3.7 Selecting of forward speed The selecting principle of tiller forward speed: the tractor cannot overload constantly; the performance of breaking soil meet the needs of agriculture requirement, furrow bottom and the soil surface are smooth. Not only be tillage quality ensured, but also the rated power of tractor be made good use of, and the purpose of rising work efficiency must be attained.
Chapter Ⅳ Maintenance To ensure that the tiller works properly, higher efficiency and prolonging the serve life, it is important that maintenance must be done properly. 4.1 Daily maintenance (after 10 hours operating) 1. Check, tighten up all of the joint bolts and nuts, tighten them up or replace them if necessary. 2.
6. Check the blades to see if there is crack, wear and tear on them, or loss. It must be replaced or added if necessary. 7. Check the blade holder, replace or repair them if necessary. 8. Repair the cover and the trailing bar. 9.

Store the machine in a dry, level area. Support the frame with planks if require. 4.6 Operation After Storage Before the machine is started up, check the following items regularly: Check oil level and add it if not enough. Check and tighten all screws and nuts; Check the regulated state of the machine.
Chapter Ⅴ Common breakdown and its fixing method Breakdowns Cause of breakdown Removing method Adjust the horizontal level of Rotary tiller failed horizontal level Universal coupling the tiller inclined too much One side sway chain of tractor is too Adjust the chain short Direction mistaken Re-assemble correctly...

Chapter Ⅵ Notes for safety 1. The operators must understand the operating characteristics and notes for safety. 2. Check the rotary tiller overall, it cannot be used until the technical condition is normal. 3. The angle of universal coupling is not more than ±10°when it is operating, and is not more than 30° when the tractor turns a corner in the field. You must dismantle the universal coupling when long-distance transporting.
