Abstract
An aerator with coring depth adjustment includes a coring depth adjust rod centrally positioned between a left side and a right side of the coring head. A portion of the coring depth adjust rod is threaded to a frame member of the coring head, and a base of the rod abuts a stop on a frame member of the aerator. The coring depth adjust rod rotates to raise and lower the coring head relative to the aerator frame to vary the coring depth.
Claims14
An aerator with coring depth adjustment, comprising:
- a frame supported by a pair of wheels adjacent a first end and a steerable wheel adjacent a second end thereof;
- a coring head on the second of the frame including a plurality of tines that reciprocate vertically to a coring depth during operation of the coring head;
- a coring depth adjust rod having a generally vertical axis and being centrally positioned between a left side and a right side of the coring head;
- a portion of the coring depth adjust rod being threaded to a frame member of the coring head, and a base of the rod abutting a stop on a frame member of the aerator to support the coring head;
- the coring depth adjust rod rotating on its generally vertical axis to raise and lower the coring head relative to the aerator frame to vary the coring depth.
An aerator with coring depth adjustment, comprising:
- a coring head mounted on an aerator frame and having a plurality of tine assemblies holding tines that are driven into the ground to a coring depth in a reciprocating manner;
- and
- a coring depth adjust rod supporting the coring head relative to the aerator frame and that rotates on a vertical axis to change the coring depth of the tines.
An aerator with coring depth adjustment, comprising:
- a walk behind aerator frame;
- a coring depth adjust rod supporting a coring head on the walk behind aerator frame;
- the coring depth adjust rod having an externally threaded area that engages an internally threaded area on the coring head frame, and having a base abutting a stop on the walk behind aerator frame;
- the coring depth adjust rod being rotatable to raise and lower the coring head relative to the aerator frame.
