Abstract

A turn mechanism for a front end rotable tined garden tiller with the capability of tilling closely to plants with minimal effort. It is comprised of a sturdy main frame, a depth regulator, two connectors with bolt holes in them which is used to connect the mechanism to the tiller, two wheel frames with a tongue on them, a tye bar for connecting the wheel frames together, and a shoulder bolt. When the shoulder bolt is down it locks the wheels in a horizontal line with the tiller and makes them stationary. When the bolt is raised up and a sleeve is pushed under the shoulder of the pin, it unlocks the wheels and by moving the handles to the right or left, the rotable tines can be turned as close to or as far away from the plants being tilled as desired. By moving the handles to the left or right the tiller will turn in a complete circle, making for a smaller turning area.

Claims1

Dependent claims

A replacement fixably pivotal wheel assembly for use with a front tined rotating garden tiller, the wheel assembly comprising:

a main frame having a front and a rear portion;
two fixably attached mounting members, each mounting member having a first and second end, the first end of each mounting member being secured perpendicular to the front portion of said main frame;
a pair of pivot holes defining a pivot axis through each mounting member adjacent to the second end of each mounting member wherein each mounting member is attached through the use of said pivot holes to a replaced wheel mounting position on the front tined rotating garden tiller;
a caster wheel assembly comprising two caster wheels wherein each caster wheel is pivotally attached to a backward-swept mounting bracket and wherein each mounting bracket is pivotally attached to both said main frame and a spacing member,
the spacing member being situated to the rear of the main frame and attached to a tongue member rearly extending from each mounting bracket thereby maintaining a predetermined spacing and relative angle between said two caster wheels;
a depth regulator assembly comprising two opposing L-shaped members secured substantially at a longitudinal mid-point of said main frame and an arcuate member slidably, adjustably situated between the said two opposing L-shaped members and
a stabilizing pin, slidably situated on a vertical axis through the main frame thereby being selectively engageable with the caster wheel assembly.
