Abstract
A jump arm assembly for a tilling machine includes a jump arm and a disc hub assembly. The jump arm has a first end coupled to a frame unit of the tilling machine and a second end opposite the first end. The disc hub assembly includes a an arm end configured to be fixedly secured to the second end of the jump arm, and an opposing disc end. A first plane defined by the arm end of the disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by the disc end of the disc hub assembly.

A jump arm assembly for a tilling machine configured to be towed across a field, the jump arm assembly comprising:
- a jump arm having a first end configured to be coupled to a frame unit of the tilling machine and a second end configured to be coupled to a tilling disc of the tilling machine;
- and,
- a variable angle disc hub assembly configured to be coupled between the second end of the jump arm and the tilling disc, the disc hub assembly comprising:
- a hub housing defining an arm end of the disc hub assembly, the arm end configured to be positioned adjacent to the jump arm;
- an end plate provided in operative association with the hub housing and defining a disc end of the disc hub assembly, the disc end configured to be positioned adjacent to the tilling disc;
- and
- a shaft including a first axial shaft section rotatably mounted within said hub housing and a second axial shaft section configured to be releasably secured to the tilling disc, said second axial shaft section being least partially threaded to receive a single threaded nut for securing the tilling disc to said disc hub assembly;
- wherein a first plane defined by said arm end of said disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by said disc end of said disc hub assembly.
A jump arm assembly for a tilling machine configured to be towed across a field, the jump arm assembly comprising:
- a jump arm having a first end configured to be coupled to a frame unit of the tilling machine and a second end configured to be coupled to a tilling disc of the tilling machine;
- and,
- a variable angle disc hub assembly configured to be coupled between the second end of the jump arm and the tilling disc, the disc hub assembly comprising:
- a hub housing defining an arm end of the disc hub assembly, the arm end configured to be positioned adjacent to the jump arm;
- an end plate provided in operative association with the hub housing and defining a disc end of the disc hub assembly, the disc end configured to be positioned adjacent to the tilling disc, said end plate including a plate body having a front surface, a rear surface, and an aperture defined through said plate body between said front and rear surfaces, wherein said rear surface of said end plate abuts said hub housing, and wherein said front surface of said end plate is configured to abut the tilling disc when the tilling disc is mounted on said shaft;
- and
- a shaft including a first axial shaft section rotatably mounted within said hub housing and a second axial shaft section configured to be releasably secured to the tilling disc;
- wherein:
- a first plane defined by said arm end of said disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by said disc end of said disc hub assembly;
- and
- said shaft extends through said aperture of said plate body such that said second axial shaft section projects outwardly from said plate body.
A jump arm assembly for a tilling machine configured to be towed across a field, the jump arm assembly comprising:
- a jump arm having a first end configured to be coupled to a frame unit of the tilling machine and a second end configured to be coupled to a tilling disc of the tilling machine;
- and,
- a variable angle disc hub assembly configured to be coupled between the second end of the jump arm and the tilling disc, the disc hub assembly comprising:
- a hub housing defining an arm end of the disc hub assembly, the arm end configured to be positioned adjacent to the jump arm;
- and
- an end plate provided in operative association with the hub housing and defining a disc end of the disc hub assembly, the disc end configured to be positioned adjacent to the tilling disc;
- wherein:
- a first plane defined by said arm end of said disc hub assembly is arranged in non-parallel relation with respect to a second plane defined by said disc end of said disc hub assembly;
- and
- the end plate is rotatable relative to the hub housing.
