Page 6: Usage
AXR-H Usage The AXR-H is a rugged disc harrow that is designed to cut, mix and pulverise plant stubble and plant residue. The AXR-H performs particularly well when breaking down large quantities of straw and plant residue, since the implement will never drag or become plugged with plant material. - Page 7 AXR-H The AXR-H must not be used as a crane, a post driver, a hydraulic press or anything similar. Operate the tractor and AXR-H only while seated in the driver’s seat. Never allow anyone to ride on the implement.

Page 8: Hook-Up And Dismounting
AXR-H Hook-up and Dismounting The linkage of the AXR-H is manufactured in compliance with DS/ISO 730-1 catego- ry II and III. If the lift of your tractor is not equipped for this, contact your DALBO representative. Hook-Up First mount the lift arms into the ball sockets (A). Elevate the lift and move the hitch jack up into the transport/working position (B). -
Page 9: Handling Without Tractor Lift Arms
AXR-H Handling without tractor lift arms If you need to move the AXR-H other than by use of the three-point hitch, we rec- ommend lifting it with straps around the middle section, raising the machine so that it hangs in balance. -
Page 10: Adjustments And Settings
AXR-H Adjustments and Settings The AXR-H is preset in the factory, but it will always be necessary to make some fi- ne adjustments before use. The numerous adjustment possibilities make your AXR- H more versatile, and allow you to get optimum performance from the implement. -
Page 11: Scrapers
AXR-H Fig. 4 Scrapers Adjust the scrapers by loosening the bolts (A), so that the scrapers can be moved. Adjust the scrapers so that there is a minimum space of 5 mm between the scrap- ers and the discs, but make sure that the scrapers never touch the discs. -
Page 12: Disc Gang Locks
Remember to disengage the locks before folding up the implement. Hydraulic locks for 6 meter AXR-H The disc gangs of the AXR-H 600 are equipped with hydraulic locks as standard. Fig. 9 The locking system is activated when folding and unfolding the disc sections. -
Page 13: Automatic Hydraulic Lock For The 6 Meter Axr-H
AXR-H Automatic hydraulic lock for the 6 meter AXR-H A fully hydraulic locking system can be mounted on the disc gangs of the AXR-H 600 if the hydraulic requirements exceed the hydraulic outlets of the tractor. After the side wings are unfolded, hold the hydraulic lever in the same position un- til the locks are activated. -
Page 14: Adjustment
AXR-H Adjustment The distance between the outermost disc and the fingers of the outer harrows can be adjusted with a pin (A), using approximately 30 cm as a standard setting. Re- member to insert the split cotter pin again. Fig. 11 Fig. -
Page 15: Operating And Driving Instructions
Never load extra weight onto the AXR-H. The AXR-H is an effective land manager and it is capable of mixing a large quantity of soil and plant residue. However, in addition to this effective land treatment, proper driving and equipment settings are required to ensure that the fields will be left uniformly level and without any ridges. -
Page 16: Folding
Secure to disengage the locks on the discgang before folding up the implement. After the side wings and the packer roller have been folded up, lower the AXR-H so that the transport lock of the wheel suspension locks firmly and securely. -
Page 17: Ridge Along The Middle
The AXR-H can be set for very light soil cultivation at a depth of only 5 cm. If work is carried out at a depth of only 5 cm, best results will be achieved through a very aggressive angling of the discs, so that the full amount of the cut can be achieved. -
Page 18: Travel Speed
When starting up, first lower the tractor lift down to the chosen depth. Then, sink the rear of the AXR-H down using the wheel frame. This special control of the im- plement provides a uniform start and stop of tillage work at the headland. -

Page 20: Maintenance
AXR-H Maintenance Proper maintenance ensures a long lifetime for the AXR-H and also optimum per- formance from the implement. To facilitate maintenance, grease fittings have been mounted on those locations where wear on the equipment is the greatest. Tighten all nuts, bolts, hydraulic fittings or any other fastened assemblies after the first workday. -
Page 21: Safety Instructions
Safety Instructions It is extremely dangerous to work or walk under the AXR-H when it is raised in the transport position unless it is securely blocked or held into position. The engine of the tractor must be stopped and the brakes must be locked. -

Page 26: Maintenance
Electro-Hydraulic Operation Electro-hydraulic operation requires only one double-acting service on the tractor. AXR-H´s functions are accessed through four electronic sockets that are mounted in a box located on the tractor. Electro-hydraulic operation is particularly an advantage when there is a lack of hy- draulic services on the tractor. -
Page 27: Bearing Protectors
Mounting Mounting of the bearing protectors must be carried out while the AXR-H is in the un- folded position and is resting on the ground. Remove the bolts from one bearing at a time and mount the bearing protector, then continue on to the next bearing. -
Page 28: Adjustment
AXR-H Adjustment Down pressure of the F-iron cage roller must be adjusted according to depth and field conditions. Fig. 23 Move the pin (A) to adjust the pres- sure of the F-iron cage roller. The pressure of the cage roller must not be greater than necessary. -
