Abstract
A cultivator for cultivating a field can have a frame with a tow assembly so that the cultivator can be towed by a tractor. A cultivating assembly can be provided pivotally attached to the rear of the frame. The cultivating assembly can have a plurality of discs that engage and penetrate the soil beneath the cultivating assembly. The cultivating assembly can have a center section pivotally connected at the to the rear end of the frame, a first wing section pivotally connected to one side of the center section, a second wing pivotally connected the other side of center section where all the sections have discs connected to them. A pair of ground wheels can be provided connected to the center section so that the ground wheels are positioned in front of the cultivating assembly when it is being used to cultivate a field.
Claims34
A cultivator comprising:
- a frame having a front end and a rear end;
- a tow assembly attached to the front end of the frame so the cultivator can be towed by a tow vehicle in a direction of travel;
- a cultivating assembly attached at a front end of the cultivating assembly to the rear end of the frame, the cultivating assembly having at least one carriage frame and a plurality of discs attached to the at least one carriage frame, each disc in the plurality of discs positioned to extend below the at least one carriage frame and come into contact with a ground surface beneath the cultivating assembly, the plurality of discs having a first row of discs and a second row of discs, the second row of discs positioned behind the first row of discs;
- a pair of ground wheels;
- and
- a finishing tool operatively and adjustably connected to the carriage frame and positioned behind the plurality of discs so that the finishing tool passes over the ground surface the discs have passed over when the cultivator is towed in the direction of travel,
- wherein a height of the carriage relative to the finishing tool is adjustable,
- wherein a height of the carriage frame relative to the ground wheels is adjustable and independently adjustable from the height of the carriage frame relative to the finishing tool, so that the height of the carriage frame relative to the ground wheels is adjustable while the height of the carriage frame relative to the finishing tool remains unchanged,
- wherein an angle of the carriage frame relative to the ground surface is alterable by independently adjusting the height of the carriage frame relative to the finishing tool and the height of the carriage frame relative to the ground wheels,
- and wherein all of the discs in the first row of discs are angled in a first direction and all of the discs in the second row of discs are angled in a second direction, the first direction being opposite to the second direction.
