Abstract
A hydraulic or electric de-thatcher power lift assembly attachment that provides control while de-thatching because it is stable and efficient and can be lifted with ease at any time when dealing with difficult terrain. In an example embodiment, the hydraulic version fits hydraulic equipped tractors. In an alternative embodiment, the device may be used with an electric motor from the tractor, or can have its own dedicated battery for power. A hydraulic or electric lift assembly is also provided for a lawn aerator. The various attachments are designed to replace the standard manual lift lever on standard aerators. The attachments can be used on tractors that have hydraulics built into the tractor or on tractors with an electric motor.
Claims13
A lifting system configured for attachment to a lawnmower or a tractor, the system comprising:
- a brace frame configured with a coupler member for coupling the brace frame to the lawnmower or tractor, the brace frame including a cantilevering arm member located on the brace frame above the coupler member and configured to cantilever vertically up and down upon actuation, the cantilevering arm member having at least one blade arm protruding laterally away from the brace frame, wherein the at least one blade arm includes an attachment member at a distal end for attaching to a lawn or farm accessory;
- and
- a lift assembly having a distal portion coupled to a lower portion of the brace frame and a proximal end coupled to the at least one blade arm, the lifting assembly configured to lift the cantilever arm up and down upon actuation, wherein the at least one blade arm with the attachment member raises and lowers the lawn or farm accessory upon actuation of the lifting assembly.
A lifting system for an aerator assembly for attachment to a lawnmower or a tractor, the system comprising:
- a brace frame having at least one lever linkage coupled to a lower portion of the base frame and a longitudinal frame above the linkage and extending laterally from the brace frame, the longitudinal frame configured to support an aerator assembly thereon with the longitudinal frame including a coupler member at a distal end for coupling the brace frame to the lawnmower or tractor, the brace frame also including a cantilevering arm member with a proximal end coupled to proximal end of the longitudinal frame, wherein the lever linkage becomes straight when the cantilevering arm is actuated to cantilever vertically up;
- a lift assembly coupled to a distal portion of the cantilevering arm, the lifting assembly configured to lift the cantilever arm up and down upon actuation, wherein the cantilevering arm raises and lowers the aerator assembly upon actuation of the lifting assembly;
- and
- a shaft with wheels assembly attached, the shaft having a proximal end of the lift assembly attached to the shaft at least at one point between the wheels, the brace frame attached via the at least one lever linkage to the shaft-wheels assembly, wherein the shaft-wheels assembly lifts the aerator accessory as the lift assembly causes the wheels to move toward the aerator, thereby lifting the aerator accessory.
