ROTARY TILLERS – Jumbo Series 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.
ROTARY TILLERS – Jumbo Series 7.4. HYDRAULIC CONNECTION If the machine is equipped with a rear roller with hydraulic cylinders, it is necessary to connect the machine hydraulics to the tractor to allow the appropriate adjustments of the roller (lifting and lowering).
ROTARY TILLERS – Jumbo Series 7.6. TRACTOR-TILLER STABILITY Before connecting the machine to the tractor is required to check the stability of the tractor- machine system, in order to determine the ballast to apply to the front of the tractor, to ensure adequate distribution of the weight on the axles.
ROTARY TILLERS – Jumbo Series CAUTION The weight of the machine modifies the stability of the system tractor-tiller, resulting in loss of steering control and braking. 5. OPERATING Before operate the tiller, make sure you have read and understood the operating manuals of the tiller, tractor and PTO shaft, and followed what is described in the section "Set Up".
ROTARY TILLERS – Jumbo Series Before the start up and before each use, make the following checks on the operating area identified for tillage: check that area is clear of foreign objects (rocks, branches or debris). Remove any obstacle and visibly highlight obstacles that cannot be eliminated (e.g.
ROTARY TILLERS – Jumbo Series if the blades strike a foreign object, or in case of prolonged intervention of the clutch due to an object wedged into the rotor, stop operating immediately, idle the engine speed and disengage the PTO. Wait for stopping of all rotating parts, then raise the implement and proceed to removing the object, after stopped the tractor, set the parking brake, stopped engine and removed the ignition key.
ROTARY TILLERS – Jumbo Series An adjustment can be done, however, when the clutch slipping is too frequent, which means that the calibration is too low. In this case, the tightening of nuts over the compressed springs will give an increase in torque transmissible.
ROTARY TILLERS – Jumbo Series SKIDS ADJUSTMENT If the tiller doesn't include a rear roller, the working depth of the machine is determined by the position of the side skids: the depth can be increased by raising the skids and decreased by lowering the skids.
