Maxiroll How to Use This Manual If the order of points described under the main subject areas of the manual seems confusing or illogical, refer to the Table of Contents where all subject headings can be found. The main points of the operator’s manual are placed into five main categories: •...
Maxiroll Application The Maxiroll is an extra rugged roller with a special construction enabling the easy attachment of additional tillage equipment. The Maxiroll is a three-section roller in which the sections move independ- ently of each other. Hydraulic weight transfer is standard on all models. Maxiroll models up to 830 have three axles, while the largest model, Maxiroll 950, has five axles.
Maxiroll Hitching and Unhitching Hitching Fig. 2 Attach the Maxiroll to the fixed drawbar of the tractor, positioning the drawbar eye of the Maxiroll (A) between the yoke end of the tractor drawbar. Insert the hitch pin and raise the drawbar jack stand.
Maxiroll Unhitching The Maxiroll must be completely folded up (in the transport position) or un- folded before unhitching. Unscrew the drawbar stand, lifting the Maxiroll drawbar from the hitch of the tractor. Remove the hitch pin and disconnect the hydraulic hoses. Remember to relieve the pressure in the hydraulic system before disconnecting the hoses.
Maxiroll Adjustments and Settings The Maxiroll is preset in the factory, but it will always be necessary to make some fine adjustments before use. Numerous adjustment possibilities make your Maxiroll more versatile and allow you to obtain optimum performance from the implement. Adjusting hitch height To ensure an even distribution of pressure on the field, the frame tube of the middle section (A, Fig.

Maxiroll Operating and Driving Instructions Proper operation is essential for optimum performance of your Maxiroll. Proper operation concerns both the carrying out of tillage operations in the field as well as the following of safety precautions. Make sure that you have a thorough understanding of all safety precautions.
Maxiroll Folding Relieve the pressure of the weight transfer to the wing sections (see ”Adjust- ing hydraulic weight transfer”). If the Crackerboard is mounted, it must be fully raised to the top position before folding (see ”Options, Cracker- board, Operating and driving instructions”). Fig.
Maxiroll Adjusting hydraulic weight transfer The hydraulic weight transfer system ensures the even distribution of weight across all sections of the roller. 1. With the roller in an unfolded position, relieve the pressure in the wing fold cylinder (marked: red). Activate the lever for the wing fold cylinder in the opposite direction (the cylinder is retracted).
Maxiroll Travel speed A working speed between 6-10 km/hour is recommended, but always drive according to conditions. When travel speed is increased, wear on the implement is increased, espe- cially under dry soil conditions. Damage to the discs may also result from driving too fast under unfavourable conditions.
Maxiroll Troubleshooting Problem Cause Action • Insufficient • Activate the lever of the hydraulic Too much pressure on middle section weight trans- wing fold, so that more pressure is ferred to wing transferred to the wings (see ”Op- sections erating and Driving Instructions”). •...
Maxiroll Options Your Maxiroll can be equipped with various types of optional equipment, de- pending on individual needs. • Crackerboard Crackerboard The greatest advantage of the Crackerboard lies in the fact that the tines can move independently and thus flex individually in response to counter pressure from land contours.

The tine angle is adjusted manually by means of the spindles (A).
Maxiroll To level the Crackerboard unit, unfold Maxiroll on a flat surface and lower the Crackerboard until the points of the tines are just above the ground. All tines must have the same distance from the ground. Fig. 17 If the middle section tines are too far down in relation to those of the wing sections, shorten the bolts (A) (there is a bolt on each side of the middle...
Maxiroll Mounting after delivery The Crackerboard can be mounted at the factory, but it can also be delivered at a later time if needed. A crane or similar equipment is required for mount- ing. Fig. 19 1 Unfold Maxiroll. 2 First mount the middle sec- tion to the flanges (A) of the drawbar.
Maxiroll Fig. 22 11 Tighten the clamp holding the hoses (A) and insert the hoses through hose clamps on the drawbar. 12 Tighten all fittings and con- nect the Crackerboard to the hydraulic system of the trac- tor. It is important to thoroughly bleed air out of the system to avoid personal injury.
Maxiroll Maintenance Proper maintenance ensures a long life for the Maxiroll and also optimum performance 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.
Maxiroll Adjustment Adjusting the rings After the first season, the rings will have worked themselves loose on the axle. By moving the collars on the axle the rings can be pushed together, eliminating the slack. The easiest way to adjust the rings is with the Maxiroll in a folded position. Fig.
Maxiroll Hydraulic System Inspect all hydraulic hoses for chafing or leaks. Check hoses for pinching. To avoid rust, any projecting piston rods should be coated with oil or grease if the Maxiroll is to be parked for a long period of time.
Maxiroll Replacements and Repairs Safety is important in connection with all repair work on the Maxiroll. The following safety precautions and the precautions listed in the beginning of this manual must be observed. Before performing any adjustments, maintenance or repairs on the machinery, always unfold the Maxiroll and lower the implement to the ground or secure in transport position, set the tractor brakes, turn off the engine and remove the...
Maxiroll After mounting the cylinder, activate the wing fold cylin- ders until the piston rods begin to move in the cylinders. Next, activate the cylinders in the opposite direction until the cylinder is back in the starting position. Move the cyl- inders several times in this way.
