Set-up instructions Preparing the tractor Before starting the operations, prepare the tractor and equipment appropriately. Check the general conditions of the tractor, especially the good functioning of the hydraulic system that must be in flotation mode. The addition of water ballasts on the tires or a set of weights on the tractor front part or on the rear wheels are the most used ways to increase the traction over the soil and to assure a greater stability of the set.
Set-up instructions Hitching to the tractor For hitching, choose a place as flat as possible. Drive the tractor slowly in reverse gear to the planter direction and be ready to brake. When close enough, use the lever to control the hydraulic position, leaving the left lower arm in the same level of the hitch pin.
Set-up instructions Coupling the cardan shaft First of all, check the cardan shaft length as follows: 1) Being the equipment properly hitched to the tractor, but without the cardan shaft, move the hydraulics to find the minimum distance (A) between the power take-off and gearbox.
Set-up instructions Reducing the cardan shaft length If it is necessary, cut similar parts of the male and female drive shaft as well as the protecting covers. But before cutting the shaft, verify all possibilities of usage without reducing its length. The length adjustment will be done when the distance between the equipment and the tractor do not allow coupling.
Set-up instructions Cardan shaft assembly When assembling the cardan shaft, it is necessary to be careful and leave the terminals on both ends aligned. The discrepancy of the terminals in 90° will cause vibrations and a greater wear on the universal joints, reducing the lifetime of the set. Observe the internal forks alignment Correct assembly Correct assembly...
Set-up instructions Equipment articulation When starting the job, lift the equipment a little to remove the blades direct contact with the field. Couple the PTO and gradually start to increase the rotation to give movement to the set of blades. Right after, move the tractor by releasing the clutch gradually and increase the rotation on the range of the allowed rotation (540 rpm) simultaneously.
Set-up instructions Assembly of the breather on the double divider Remove the plug (A) from the double divider and place the breather (B). At this moment, check the oil level using the plug (C) on the gearbox side. If it is necessary to fill up the gearbox, pour oil until reaching the plug (C) level. The oil level must be adjusted according to the indication in the markers, being the rotary cutter in a flat place.
Set-up instructions Assembly of the oil level marker with breather Remove the plug (A) from the gearbox and from the velocity transmission and place the oil level marker with breather (B). At this moment, check the oil level by just placing the marker on the hole without tightening it;...
Set-up instructions Longitudinal leveling Use the length variation of the third-point arm (A) to adjust the longitudinal leveling, so it is possible to level or unlevel the front part of the equipment related to the rear part and vice-versa. The more stretched is the third-point (A), the lower will be the rear part of the equipment.
Set-up instructions Working position (RC² 2600 CL and RC 3100 CL models) These rotary cutters can work in a central or lateral position related to the tractor. If it is necessary to change the position, follow the instructions below. • Loosen the bolts that fasten the angle bar (A) without removing them. •...
Adjustments and operations Direction of blades rotation and serial number • The blades feature a double cut so it is possible to use both of their sides NOTE and also for a greater time. To do so, just place the blades that are turning on a clockwise direction on the support that is turning on a counterclockwise direction and vice-versa.
Adjustments and operations Cutting height of the blades Being the equipment leveled, adjust the cutting height of the blades as follows: Use the hydraulic lever to determine the cutting height. After this adjustment, keep the lever locked during the whole job and just activate it if it necessary to change the cutting height;...
Adjustments and operations Equipment transportation The equipment transportation while it is coupled to the tractor must not be done over public highways or roads. This practice must be limited to rural properties only. If there is the need to transport the equipment over public highways or roads, consult the traffic current laws to check if it is possible to transport the equipment and to avoid any setback.
Adjustments and operations Slip clutch The slip clutch is adjusted on the factory, so it is not necessary to adjust it when using the equipment. When facing overloads, the slip clutch starts to work. Immediately lift the equipment to relief the overload. NOTE •...
Adjustments and operations Troubleshooting guide PROBLEM CAUSES POSSIBLE SOLUTIONS Worn out or broken blades. Replace them. Incorrect PTO rotation speed. Correct rotation speed: 540 rpm. Excessive speed. Reduce the speed. Blades do not work when the PTO Check the connection of the transmission Blades do not is switched on.
Adjustments and operations Operations - Important points • Before starting working, it is advisable to do a complete check on the cutter. Grease the universal joints, check the oil level in the gearbox and tighten nuts and bolts. • In order to couple and to uncouple the cardan shaft, the PTO should be disengaged.
Optional Stabilizer set The stabilizr set (A) is optionally supplied to transfer part of the equipment weight to the rear axle of the tractor to relieve the hydraulic system. This set has a chain (B) adjustment, being necessary to loosen up the pins (C) and determine the desired length.
Page 38
Optional Rear laminated tire The rear laminated tire (A) can be optionally supplied to relieve the weight on the three-point hitch and to help on the cutting height adjustment. NOTE • The rear laminated tire can help adjusting the cutting height of the blades through the holes that can be found on the fixation support.
Maintenance Lubrication Observe daily if the nuts and bolts are tightened and the conditions of the pins and cotter pins. The maintenance of the gearbox should be done in the following way: • When starting to work and everyday of the first working week, check the oil level through the level indications and fill up if necessary.
Maintenance Reversion or replacement of the blades Inspect blades before each use to determine if they are properly installed and in good conditions. Replace any blade that is bent, excessively nicked, worn or has any other damage. Besides that, the blades must be replaced as soon as some cutting imperfection is being noticed.
Maintenance ATTENTION • When replacing the blades, observe that they are supplied in pairs, which should be kept together until assembled on the cutter spindle. Unbalanced blades may cause excessive vibration and can damage bearings, retainers and the transmission box. • The discrepancy in weight of these blades is within the tolerance specified in the project.
Maintenance Blades overlap These rotary cutters have blades that overlap to assure the cut over the whole job area to compensate a possible wearing on the blades, leading to cut failures. If the transmission box (distributor or gearbox) or the supports receive a maintenance that alters the factory- adjusted synchronism, resync the blades to assure that they will not collide when turning.
Maintenance Transmission coupling set assembly For the RC² 2600 CL and RC² 3100 CL models. Assemble the terminals (A) to the gearbox axles without tightening the bolts for now. Position the coupling (B) between the terminals and place the double chains (C) with their respective lock pins.
Maintenance Slip clutch The slip clutch is assembled both in the gearbox and in the cardan shaft, being also assembled in the metering box shaft. It is designed to slip, absorb operation loads and to protect the drive shaft. The slip clutch is factory fitted with a specified torque, in order to protect the tractor and equipment.

Maintenance Slip clutch Check the average length of the compression springs (D) before disassembling them. Disassemble and sand the metallic parts that are attached to the plates. Being the clutch disassembled, the plates must swing freely between the metallic parts. Replace the plates (B) when their thickness get to 1.5 millimeters.
Page 46
Maintenance Wheel lubrication The wheels must be lubricated every 150 hours. When there is any clearance, it is necessary to give maintenance to the wheelset hubs. Disassemble the hubs and remove the inner components. Clean all parts with diesel oil or kerosene. Check the existence of clearances and the condition of the bearings and retainers.
Page 47
Maintenance Gearbox The gearbox must be inspected every time the rotary cutter is about to operate. If the oil level is low, fill up the rotary cutter. The oil level verification must be done in a flat place and adjusted according to the indications of the marker.
Important data Torque table The table below gives correct torque values for various bolts. Tighten all bolts to the torques specified in chart unless otherwise noted. Check the tightness of bolts periodically, using this bolt torque chart as a guide. Replace hardware with the same strength (Grade/ Class) bolt.
