Abstract
An improvement for no-till rotary hoes to prevent trash from accumulating around a bearing of the rotary hoes thus destroying the bearing. An elongated axle mounts a hoe wheel distant from its corresponding support arm and in close proximity to an adjacent support arm, and the axle is protected by a spring-loaded protective sleeve which is spring loaded to provide a frictional seal against the bearing of the hoe wheel.
Claims19
An apparatus for mounting a rotary earthworking implement assembly including a bearing having a stationary portion and a rotating portion onto a support arm adapted for attachment to a tool bar comprising:
- an elongated axle between each earthworking implement and a corresponding support arm for supporting such rotating implement assembly through the bearing for rotation on the axle, the rotating implement assembly being laterally spaced from the support arm;
- and
- a non rotating rigid sleeve substantially surrounding the axle and having an end frictionally abutting a rotating portion of the implement assembly radially outward from the bearing as the implement rotates.
An improvement for rotating earthworking implements arranged into rows having a first row in advance of a second row, each implement being supported on a support arm which is attached to a tool bar, the improvement comprising:
- an elongated axle between each implement and a corresponding support arm, each elongated axle laterally spaces each implement in the first row nearer an adjacent support arm for the first row than its corresponding support arm for the first row and laterally spaces the implements in the second row nearer an adjacent support arm for the second row than its corresponding support arm for the second row;
- and
- means for protecting the elongated axle and a bearing, wherein the means for protecting the elongated axle and the bearing comprises a spring loaded sleeve which frictionally abuts the implement at a location radially outwardly from the bearing on the implement as the implement rotates, wherein the sleeve is of substantially fixed length.
An improvement for rotating earthworking implements arranged into rows having a first row in advance of a second row, support arm means for rotatably supporting each implement for working, the improvement comprising an elongated axle between each implement and the corresponding support arm means, the elongated axle for each implement laterally spaces the respective implement in the first row nearer an adjacent support arm means in the first row than the corresponding support arm means for the respective implement in the first row, and laterally spaces the respective implements in the second row nearer an adjacent support arm means in the second row than the corresponding support arm means for the respective implement in the second row.
An improvement for rotating earthworking implements arranged into rows having a first row in advance of a second row, support arm means for rotatably supporting each implement for working, the improvement comprising an elongated axle between each implement and a corresponding support arm means, each elongated axle laterally spaces the implements in the first row nearer an adjacent support arm means for the first row than its corresponding support arm means for the first row and laterally spaces each implement in the second row nearer an adjacent support arm means for the second row than its corresponding support arm means for the second row.
