Checking the Ballast Requirements Setup Inspecting the Machine WARNING Mounting the machine to the rear of the traction unit decreases the weight on its front axle. Checking the Grease and Gearbox Check and ensure that the gearbox has fluid; refer to Checking the Gearbox Lubrication (page 21). Failure to add required ballast may result in an accident and severe injury or death. Ensure that the machine is greased before use; refer to Greasing the Attachment (page 21).

Operation Important: Refer to the traction unit operator's manual for operating instructions. Note: Determine the left and right sides of the machine from the normal operating position. Practicing the Operating Procedures Before Operation Before using the machine, find a clear area and practice operating the traction unit with the machine installed.
6. Secure the lower link arms to the hitch pins using the hairpin cotters. Connecting the Upper Link Arm 1. Connect the upper link arm to the bracket and secure it with the link pin and the hairpin cotter (Figure 8). Note: Use the slotted hole if you want the attachment to follow the terrain during operation. g345540 Figure 6 1. Hairpin cotter (3) 2. Hitch pin (3) 3. Back the traction unit squarely up to the attachment so that you can attach the lower connecting arms to the frame. 4.
1. Park the machine on a level surface, engage the parking brake, and lower the attachment to the ground. 2. Shut off the engine and remove the key. 3. Pull the PTO driveshaft sections apart (Figure 9). g347461 Figure 9 4. Assemble the outer PTO driveshaft section to the traction-unit PTO output shaft (Figure 10). Note: Pull on the driveshaft to ensure that the locking pin engages the PTO output shaft. g347524 Figure 11 1. 76 mm (3 inches) 3. Traction-unit PTO output shaft 2.
g347459 Figure 13 9. Assemble the outer PTO driveshaft section to the PTO shaft of the traction unit (Figure 10). 10. Raise the attachment to the position where the traction-unit PTO output shaft and gearbox input shaft are furthest apart (Figure 14). 11. Hold the driveshaft sections parallel to each other and check to ensure that they overlap 150 mm (6 inches) or more (Figure 14). Note: If the sections do not overlap 150 mm (6 inches), contact your authorized distributor. g347621 Figure 14 1.
Installing the PTO Driveshaft Important: Refer to the PTO driveshaft owner’s manual for additional operating and safety information. CAUTION Operating the machine without the PTO guards and shields may cause injury or death. Keep all PTO guards and shields in place. g345541 Figure 16 Important: When connecting the PTO, ensure that the attachment is not lifted higher than necessary. Lifting the attachment too high causes the PTO driveshaft knuckles to break (Figure 15).
5. Verify that the telescoping tube has a minimum of 150 mm (6 inches) overlap when the attachment is raised to the maximum height. g346323 g345507 Figure 19 Figure 18 1. Rear link 2. Jam nut 4. Rear link 5. Long slot in gauge 3. Gauge Connecting the Hydraulic Hoses 1. 2. Connect the hydraulic hoses from the attachment to the traction unit. Ensure the hydraulic hoses are engaged in the ports. Confirm that the traction unit levers operate the attachment hydraulics.
During Operation During Operation Safety • The owner/operator can prevent and is responsible • • • • • • • • g346328 Figure 20 1. Front link 3. Adjustment positions 2. Jam nut 4. Front indicator • • • • Transporting the Machine To prevent losing control of the machine, move slowly across steep inclines and approach rough, undulating areas slowly and carefully. • Important: Do not exceed 12 km/h (7.5 mph) while transporting the attachment. 1.
Tall grass can hide obstructions. Uneven terrain could overturn the machine. – Engage the parking brake. – Lower the attachment. • Be aware that operating the machine on wet – Shut off the engine and remove the key. grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. – Wait for all moving parts to stop before leaving the machine.
g345626 Figure 21 1. Breakage occurs here. 1. Drive to the location where you will use the attachment 2. Inspect the area where you will use the machine and remove all objects that the machine could strike. 3. Locate and mark all electrical or communication lines, irrigation components, and other obstructions in the area. g346288 Figure 22 4. Park the machine on a level surface and lower the attachment. 1.

14. Engage the traction unit PTO at a low engine speed. 15. Increase the traction unit PTO speed to approximately 300 rpm. 16. Drive the traction unit forward slowly and allow the attachment to smoothly lower onto the rollers. Note: Ensure the second machine is following to collect the debris. 17. Slowly lower the attachment until it reaches the working depth. 18. Drive forward and increase the rotational speed until the PTO driveshaft speed reaches 540 rpm. 19.
Operating Tips 3. Lower the attachment onto the rollers. • Engage the PTO at low engine speed. Lower the 4. machine and increase engine speed to achieve a PTO speed of 540 rpm (maximum). Operate the engine at a speed that the machine runs most smoothly. Shut off the engine and remove the key from the traction unit. 5. Remove the hydraulic hoses from the traction unit. 6. Remove the top link from the attachment. • Make very gradual turns. Never make sharp turns with the machine lowered.

Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 20 hours • • • • • Grease the PTO shaft and roller bearings. Check the gearbox oil level. Check the gearbox for leaks. Check the V-belt tension. Check for loose nuts and bolts. Before each use or daily • • • • • Check Check Check Check Check the gearbox oil level. for loose nuts and bolts. the PTO shaft. the hydraulics. the conveyor belts.
Greasing the Attachment Service Interval: After the first 20 hours After each use Every 50 hours Grease the bearings and bushings after cleaning the machine. The attachment has grease fittings that you must lubricate regularly with No. 2 lithium grease. Also, lubricate the attachment immediately after every washing and after long periods without use. g007309 Figure 28 Grease the machine at the following bearing locations (Figure 27).
Changing the Gearbox Lubrication 2. Service Interval: Every 500 hours Note: If the tension is correct, install the belt The gearbox is filled with SAE140 gear oil or equivalent. 1. Clean debris from the fill plug and the drain plug to avoid contamination (Figure 29). 2. Remove the fill plug to relieve trapped air. 3. Position a short drain pan under the drain plug and remove the drain plug. Check the tension of the V-belts by pushing point A with a pressure of 7.5 kg (16-1/2 lb).

Lower screw If the conveyor belt starts slipping or moving sideways after use or after new installation, adjust the conveyor belt tension. 1. Check if the rollers and the inside of the conveyor belt are clean. If necessary clean the rollers and remove any dirt inside. 2.
8. After each adjustment, allow the conveyor belt to rotate for at least 10 rotations to position itself to the new alignment before making any further corrections. 9. If the belt is working properly again, securely lock the screws in place. Cleaning the Machine Service Interval: After each use Important: Do not use brackish or reclaimed water to clean the machine.
Installing Scarifying Knives This machine is equipped with cutting knives, but you can also equip it with scarifying knives (if required) for scarifying the subsoil. You can set the distance between the scarifying knives at the following 4 positions: • 20 mm (0.79 inches) • 40 mm (1.6 inches) • 60 mm (2.36 inches) • 80 mm (3.15 inches) There are 8 rows on the rotor (Figure 34). Each row has 4 plates.

Storage Storage Safety • Before adjusting, cleaning, storing, or repairing the machine, park the it on a level surface; engage the parking brake of the traction unit; shut off the engine; remove the key; and wait for all movement to stop before leaving the traction unit. • Store the machine on the front and rear rollers positioned on a firm, level surface so that it does not sink or roll away. • Store the machine away from areas of human activity.
Troubleshooting Problem The machine vibrates. The working depth is not achieved. The soil is too coarse while processing. The rotor is jammed. The rotor does not turn. The transport belt cannot handle the quantity of material. The transport belt moves slowly or does not move. Possible Cause Corrective Action 1. There is an obstacle(s) between the knives 1. Remove the obstacle(s). 2. The knives are worn or broken. 3. The rotor is unbalanced. 2. Replace with new knives. 3. Balance the rotor. 1.
