Designed to be a versatile and clogging-proof harrow, the Solver model is the most complex in our range. In good conditions, the Solver harrow can successfully carry out spring stubble cultivation and seedbed preparation in lightly tilled and ploughed fields. Solver’s frame properties and s-tines, which offer excellent features, are the secret behind Solver’s cultivating power. The relatively long and rigid frame offers exceptionally high power and penetration for cultivation. Thanks to its versatility, more and more farmers are choosing Solver for spring tine harrowing – Join the growing group of satisfied users.
Solver harrows are equipped with high 10x65 spring tines, whose geometry and height allow for good penetration of plant residue. The spacing between the tines is also more open than in traditional s-tine harrows, and the tine distribution is even. The penetrative tine distribution makes it possible for the biomass to pass through the harrow without clogging it. The 120mm tine spacing, 8 tine axles and 3.3m long frame offer great possibilities for spring tine harrowing even when working with stubble.
Solver’s effectively vibrating tine combined with a 60mm point provides an even cultivation bottom. The height of the tine, its cross-sectional profile and geometry mean that the tine vibrates strongly and has good pulverising ability. The front crossboard and following accessories make pulverisation more effective. Solver is always available equipped and ready to meet the needs of the farm and soil types.
Solver is an excellent option for farms which use intensive tillage on light types of soil. Solver’s powerful levelling properties make a great seedbed and a great base for silage grass. Any root balls or heavy crop residue that might be present in the soil is not an issue due to the penetrative structure of the harrow.
Solver can also be used to introduce new cultivation methods, such as spring straw harrowing, where the distribution of straw over the field can be levelled out, or minimal tilling in the autumn, which makes weeds and spill seeds sprout, so that the field is cleaner the following growing season. When equipped with goosefoot blades, Solver is also an excellent choice for managing perennial weeds.
The S-tine’s geometry means that the tine retains its cultivation depth even in the harshest conditions. Thanks to its height, geometry and cross-sectional profile, the 10x65 tine also vibrates extremely effectively to achieve a high pulverising capacity. In addition, the tine’s strong lateral vibration contributes to an even cultivation result.
Solver spring tine harrows are equipped with load-bearing 250/65-14.5 wheels. The wheels have a width of 250 millimeters and a diameter of 675 millimeters so that the harrow can function in all conditions and in different types of soil without any changes to its working depth. All bogie beams and wheel hubs have conical roller bearings to provide a long service life for the harrow.
The front spring crossboard cultivates, pulverises and levels the surface of the field. Combined with the weight of the harrow, the strong 10 x 80 spring and shaped point make it possible to level the surface of the field and to pulverise clods. If necessary, the front crossboard can also be equipped with a stabilizer bar, which will make the front crossboard act more like a beam.
Solver spring tine harrows use a sturdy 3.29 metre-long frame. The tines are located along the frame on eight tine axles to effectively prevent the harrow from becoming clogged. The harrow frame’s sturdiness also achieves sufficient tine weight and the tine will not move to a shallower cultivation depth even in stiff soils.
The spring tine harrow’s wheels are installed on four axles to keep the motion of the harrow steady. The wheels on different axles prevent the harrow from dipping. The steady movement of the harrow through the field ensures level cultivation and makes harrowing easier.
The working depth of the Solver spring tine harrow is adjusted using a ingenius memory cylinder. The depth can be adjusted from the tractor cab without the driver needing to climb on the harrow. This is a great feature in fields where the type of soil can vary lots. Hydraulic adjustment is extremely precise, and even extremely minor adjustments are possible.
Potila harrows have clear and easy-to-read scales for adjusting working depth and crossboards. The scales for the front part of the frame are ergonomically placed to the front-right, which makes it effortless to check the working depth and crossboard position. The front crossboard’s scale is integrated into the front crossboard and the rear crossboard has its own scale to the rear of the harrow.
A cage roller is best in conditions where you need high pulverising power and there is lots of crop residue in the field. The cage roller’s small diameter means it has great pulverising power. Extensive weight and height adjustments mean that performance is always optimal and, if necessary, it is possible to harrow with the cage roller lifted.
A rear crossboard is at its best in aggressively cultivated soil where there isn’t much crop residue. The rear crossboard has high pulverising capacity, and it also effectively levels the surface of the field. In ploughed fields, the double crossboard technology achieves an extremely level and pulverised seedbed.
The 2-row rear harrow has an extremely high penetration ability, which ensures that the harrow functions well even when there is a lot of crop mass. The harrow can be extensively adjusted for any and all conditions.
