Abstract
The present invention is a mounting device for individually mounting rotary hoes on the shanks of row crop cultivators. The tractor pulls shanks through the fields to cultivate the soil with rotary hoes connected to the shanks by a mounting device. The mounting device includes a portion which clamps to the shanks and a portion which is pivotally connected to the clamping portion and extends to a rotatably mounted rotary hoe. The hoe may float over irregular surfaces of the ground to penetrate and dig up the soil. The rotary hoes may be biased by a spring to maintain a relatively constant ground depth, and they may include stops to limit their forward movement, backward movement, or both.
Claims17
A row crop cultivator adapted to be pulled by a tractor, said row crop cultivator comprising:
- a plurality of closely spaced shanks arranged as a row unit operably connected to the tractor;
- a rotary hoe including a wheel and a plurality of projections radially extending from said wheel, said projections adapted to penetrate and agitate the ground;
- and
- means for attaching said rotary hoe between any two adjacent ones of said shanks, said attaching means including mounting means for adjustably mounting said attaching means on any portion of one of said adjacent shanks, said mounting means also including a plate having means for pivotally supporting said rotary hoe, said attaching means including an arm which positions said rotary hoe adjacent one of said shanks such that the arm pivots in an arc so that said projections of said rotary hoe impinge the soil as the soil is tilled by said shanks, said arm associated with said plate and including a stop block mounted on said arm which limits the pivoting arc of said arm by abutting said plate, whereby said rotary hoe independently floats over the surface of the ground being cultivated.
A row crop cultivator adapted to be pulled by a tractor, said row crop cultivator comprising:
- a plurality of closely spaced shanks arranged as a row unit operably connected to the tractor;
- a rotary hoe including a wheel and a plurality of projections radially extending from said wheel, said projections adapted to penetrate and agitate the ground;
- and
- means for attaching and rotatably supporting said rotary hoe between any two adjacent ones of said shanks, said attaching means adjustably mounted on one of said adjacent shanks, said attaching means pivotally positioning said rotary hoe relative to said one shank so that said rotary hoe floats over the surface of the ground being cultivated, said attaching means including a bushing and means for clamping said bushing at any position on the shank, said attaching means further including an arm for connecting said bushing to said rotary hoe, said arm including a pivot shaft disposed in said bushing, said attaching means including a spring disposed around said pivot shaft and biasing said rotary hoe relative to said one shank and against the ground.
A cultivator for tillage of soil in preparation for planting rows of crops, said cultivator adapted to be pulled by a tractor, said cultivator comprising:
- a plurality of closely spaced shanks arranged for deep soil tillage, said plurality of shanks arranged such that at least two of said shanks are positioned between a crop row, said plurality of shanks being operably connected to the tractor;
- a rotary hoe including a wheel and a plurality of projections radially extending from said wheel, said projections adapted to penetrate and agitate the ground;
- and
- means for attaching said rotary hoe to any one of said plurality of shanks, said attaching means including mounting means for adjustably clamping said attaching means on one of a plurality of portions of said one shank, said mounting means including a first plate with a hollow portion defining a bushing, a second plate, and means for clamping said first and second plate at any position on the shank, said attaching means also including means for rotatably supporting said rotary hoe, said rotatably supporting means including an arm for connecting said mounting means to said rotary hoe, said arm including a pivot shaft disposed in said bushing, said arm extending from one side of said one shank and being pivotally connected to said mounting means, said attaching means positioning said rotary hoe adjacent one of said shanks so that said projections of said rotary hoe impinges the soil as the soil is tilled by said shanks whereby said rotary hoe independently floats over the surface of the ground being cultivated.
