Before operating the tiller ensure that the size of driveshaft is adequate The driveshaft supplied with the machine has a standard length therefore it may need an adaptation of the length depending of the tractor which the tiller is combined The length of the driveshaft must be such to e avoid bottom out of the transmission tubes when the driveshaft is in compressed position when tiller is raised up off the ground e ensure an overlapping of the transmission tubes enough to transmit the torque required when the driveshaft is in max extension when tiller is in its lowest position in the ground When the driveshaft is at its minimum length max compressed position there must be at least a 2 cm of distance between the ends of each transmission tube and the yokes side When the driveshaft is at its maximum operational extension there must be an overlap between the tubes profiles of 15 cm at least 15cm MAX EXTENDED POSITION 2cm 4 MAX COMPRESSED POSITION A driveshaft too long may cause structural damages to the tractor and machine If the driveshaft is too long it may be adapted by removing it and shortening the tubes according to the instructions provided by the manufacturer in its use and maintenance manual A driveshaft too short can cause disengage of the tubes during operation with severe hazard for the operator and structural damage to the tractor and machine If the driveshaft is too short it must
