Page 16: Lower Hitches Positioning
RC-Series Rotary Cultivators 4.1. LOWER HITCHES POSITIONING The RC-SERIES Cultivators are designed to be mounted on tractors equipped with: 3-point Hitch Category I (ISO 730 standard); Quick Hitch Category I (ASABE Standard). The position of the lower hitches must be adjusted accordingly. If the tractor is equipped with a Quick Hitch Category I (ASABE Standard), verify that the lower clevises show the pins oriented up (see figure), so that the distance between upper and the lower pins is 15'' (381 mm), as required from the standard. -
Page 17: Connecting To The Tractor
RC-Series Rotary Cultivators invert the clevis orientation and reposition it on the square tube at distance of 13 7/16'' from the center of Cultivator PTO. At the end of the operation the lower clevises should be positioned symmetrically respect to Cultivator PTO, at distance of 26 7/8'' (683 mm); ... -
Page 18: Driveline Length Check
RC-Series Rotary Cultivators hook to the tractor and Cultivator the two retaining chains of the the driveline shielding, to prevent shielding rotation during functioning of the machine. DRIVELINE LENGTH CHECK Before operating the Cultivator, 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 Cultivator is combined. -
Page 19: Tractor-Cultivator Stability
RC-Series Rotary Cultivators IMPORTANT before operating the Cultivator the first time, make sure that the driveshaft is lubricated in accordance with how indicated in the instruction booklet; before operating the Cultivator the first time, and after long periods of inactivity, make sure that the driveline clutch has run a short "run in"... - Page 20 RC-Series Rotary Cultivators check that the driveshaft clutch is in good condition, and that its components are not subject to "sticking" (see section: Maintenance / Driveline); check the presence of lubricant in all greasing points of the Cultivator (driveshaft, supports...) (see sect.

Page 21: Operating Instructions
RC-Series Rotary Cultivators 5.2. OPERATING INSTRUCTIONS During operations:/ OPERATE ACCORDING TO FOLLOWING INTRUCTION always keep the tractor engine at rpm rate ensuring to the Cultivator the right power required for the use; always keep a tractor speed adequate to conditions of the soil to be worked (from 2 to 10 km / h approx.). -
Page 22: Friction Clutch Adjustment
RC-Series Rotary Cultivators FRICTION CLUTCH ADJUSTMENT The PTO driveshaft and friction clutch are designed to transmit adequate power to the Cultivator. The clutch preserves the machine from overloads, through the slipping of friction discs, and limits the max torque transmissible to a calibrated value set at factory. It is recommended, therefore, to leave unchanged this value to avoid damages to the machine or to driveshaft. -
Page 23: Skids Adjustment
RC-Series Rotary Cultivators The manufacturer is not liable for damages resulting from a wrong modification of the clutch calibration. NOTE Excessive tightening of the springs can prevent the clutch from slipping and to protect the machine from overload. Make sure that the height of all the compressed springs is equal to prevent clutch malfunctioning. SKIDS ADJUSTMENT The working depth of the Cultivator is determined by the position of the side skids: it may be increased by raising the skids, and decreased by lowered them. -
Page 24: Rear Board Adjustment
RC-Series Rotary Cultivators The position of the rear board is adjustable by varying the number of chain links included between distance XY, which remain tensioned under the weight of the board (i.e. links between the rear board U-bolt 1 and the slot of the frame 2). ... -
Page 25: Transporting
RC-Series Rotary Cultivators To disconnect the Cultivator from the tractor (e.g. to make a change of implement): adjust the skids to their lowest position (see Section Adjustments); adjust the parking stand to the lowest position, through the use of relative retaining pin; ... -
Page 26: Blades Replacement
RC-Series Rotary Cultivators compromise the functioning and duration of the machine, and consequently invalidate the warranty. The frequency of maintenance indicated refers to normal conditions of use: it must be intensified in severe operating conditions (frequent stops and starts, prolonged winter season etc ...). Repairs, maintenance and modifications other than those mentioned in this paragraph should NOT be performed without consulting the manufacturer or your dealer. -
Page 27: Gearbox Lubrication
RC-Series Rotary Cultivators Periodically check the tightness of screws and nuts, and tighten if necessary. IMPORTANT Remove and install one blade at a time to ensure blades are correctly oriented when installed. Replace worn blades only with original parts. CAUTION Worn tines may be very sharp! 6.2. -

Page 29: Bearing Housing Lubrication
RC-Series Rotary Cultivators To make the oil change: remove the skid from the transmission side; place a tank under the oil level plug; unscrew the oil level plug and drain completely the oil into the tank; retighten the level plug; ... - Page 30 RC-Series Rotary Cultivators IMPORTANT For details about maintenance and lubrication of the driveshaft, refer to the user manual of the driveshaft manufacturer. Driveshaft clutch: Exposition to the elements of Cultivator and driveshaft, or a long period of inactivity, generally results in oxidation of some clutch components, and creates "sticking" effect on the clutch. Consequently, the torque required to the slippage of the clutch increases considerable respect to the value set at factory, and this may be cause of driveshaft breakage during operation, or damage to the tractor or implement.
