Use straw chopper machine using one of a field machine, the job should be first field machine claw hammer raised to 20-25 cm in height from the ground (to enhance the position can not be too high to prevent excessive gimbal angle big damage) engage PTO shaft rotation for 1-2 minutes, hang work gear, slowly release the clutch pedal loose (if necessary when using a secondary clutch with tractor -55), while operating the hydraulic lift adjustment handle, so to field gradually reduced to the required machine stubble height, along with the throttle, put into normal operation. 2, when the job is prohibited claw hammer hit the soil, prevent infinite increase the torque caused by the fault. If found claw hammer hit earth, should be adjusted to the length of the wheel above the ground or hung on a tractor trolley. 3, should turn the field machine upgrade, before landing work after the turn. Field machine upgrade, should pay attention to a smooth landing, work backwards ban must be cut off output power after the tractor on the road transport. 4, the job should pay attention to remove grass wrapped to avoid soil ridge, stumps and other obstacles, 3-5 meters left edge of the rotary unit area. 5, when the job if there is an abnormal sound heard should immediately stop inspection, troubleshooting before continuing operation. 6, the job should always check the tightness of the belt, so as not to reduce the impact of the knife shaft speed and crushing quality and increased belt wear. Second, the safe operation and precautions 1, the operator must first become familiar with the performance of equipment, according to the manual operation of machinery. 2, use should be raised prior to the 30th transmission gear oil, the oil level in the gear oil immersion third appropriate. 3, gimbal installation should pay attention to the following three points: A. should ensure that lifting equipment at work, square shaft and casing and top ends of the cross is not dead, but also with enough length. Section B. universal mounting position and orientation should be correct, if installed wrong direction, it will produce a sound and strong vibration, and increased damage to joints. C. 55,60 drowned rat when the tractor supporting strut cylinder should be replaced by a fixed flat iron, so as not to collide with each other when the gimbal rotation. 4, moisture is too large non Shimoda job.
