Abstract
A furrow closing system for an agricultural seed planter provides soil closing and soil pressing that are controlled by independent adjustable down force or pressure systems that react to a common frame element or backbone. The adjustable down force systems may be manually controlled, electronically controlled and/or part of a closed loop system. A down stop, which may also be adjustable, may be used to limit the maximum force of the adjustable down pressure systems.
Claims8
A method for closing a furrow with an agricultural seed planter including a frame element, first and second adjustable down-force assemblies coupled to the frame element, a closing assembly coupled to the first adjustable down-force assembly, the closing assembly operable to contact a ground surface, and a press assembly coupled to the second adjustable down-force assembly, the method comprising:
- (a) contacting a ground surface with the press and closing assemblies with the press assembly following the closing assembly;
- (b) adjusting a first down force from the frame element to the closing assembly via the first adjustable down-force assembly without substantially affecting the press assembly;
- and
- (c) adjusting a second down force from the frame element to the press assembly via the second adjustable down-force assembly without substantially affecting the closing assembly.
A furrow closing system for an agricultural seed planter comprising:
- a frame element;
- a closing disc operable to contact a ground surface;
- a closing arm pivotally coupled to the frame element and the closing disc;
- a first adjustable down-force assembly pivotally coupled to the closing arm;
- a press wheel;
- a press arm pivotally coupled to the frame element and the press wheel;
- a second adjustable down-force assembly pivotally coupled to the press arm;
- and
- a down stop limiting a motion of the closing arm,
- wherein the press wheel is operable to contact a ground surface following the closing disc, and
- wherein the first adjustable down-force assembly is operable to provide a first adjustable down force from the frame element to the closing disc without substantially affecting the press wheel, and the second adjustable down-force assembly is operable to provide a second adjustable down force from the frame element to the press wheel without substantially affecting the closing disc.
