Abstract
An apparatus and system for positioning a trailing wheel behind a row planting unit in a row planting system and for transferring weight between a row closing unit with row closing wheels and a trailing wheel while providing for independent movement of the trailing wheel and row closing wheels is provided. A trailing or firming wheel assembly is positioned behind a row closing unit with a set of row closing wheels. A cam-based depth limiting system provides for a depth stop and depth limiting adjustments while providing for independent movement of the trailing wheel and set of row closing wheels.
Claims20
A two-stage row closing system, the system comprising:
- a first stage row closing unit;
- and
- a second stage row closing unit, the second stage row closing unit comprising:
- a first frame assembly fixedly secured to the first stage row closing unit;
- a second frame assembly rotatably secured to the first frame assembly such that the second frame assembly may move independently relative to the first frame assembly;
- and
- a depth limiting assembly adapted to provide an upper limit on the rotational movement of the second frame assembly relative to the first frame assembly.
The two-stage row closing system of claim 20, wherein the depth limiting assembly comprises a cam and cam stop.
The two-stage row closing system of claim 7, wherein the wheel assembly comprises a firming wheel.
A row closing unit, the row closing unit comprising:
- a first frame assembly fixedly secured to a frame of a first stage row closing unit;
- a second frame assembly rotatably secured to the first frame assembly such that the second frame assembly may move independently relative to the first frame assembly;
- and
- a depth limiting assembly adapted to provide an upper limit on the rotational movement of the second frame assembly relative to the first frame assembly.
