Abstract
An attachment arrangement and method for mower reel drive wherein the rotating reel has its shaft rotatably mounted on a mower frame, and a rotational drive motor is also mounted on the frame. The facility of making the connection between the motor and the frame and of aligning the parts along a longitudinal axis for the drive relationship, are both involved, and pin connections are employed to achieve those objectives.
Claims12
An attachment arrangement for rotationally driving a reel of a mower comprising:
- a mower reel shaft,
- a reel frame for rotationally supporting said shaft,
- a bearing housing having a longitudinal axis and having a central opening extending along said longitudinal axis and said bearing housing being mounted on said frame,
- an adapter having a protrusion extending snugly into said central opening,
- a pin fixed with and extending from said adapter and into said bearing housing,
- said bearing housing having an opening therein extending radially of said longitudinal axis and being in intersection with said pin,
- a clamp located in said radial opening and being releasably engagable with said pin for clamping said pin upon tightening said clamp,
- a threaded member on said clamp for tightening said clamp and thereby releasably holding said adapter onto said bearing housing, and
- a motor attached to said adapter and being in an operatively driving relationship with said shaft.
An attachment arrangement for rotationally driving a reel of a mower comprising:
- a mower reel shaft,
- a reel frame for rotatably supporting said shaft,
- a bearing housing having a longitudinal axis and said bearing housing being mounted on said frame and rotatably supporting said shaft,
- a motor for drivingly rotating said shaft,
- a pin interconnected with said motor and extending to said bearing housing,
- a releasable clamp located on said bearing housing and being releasably engagable with said pin for clamping said pin upon tightening said clamp, and
- a threaded member engageable with said clamp for tightening said clamp and thereby releasably holding said motor on said bearing housing and with said motor being in an operatively driving relationship with said shaft.
An attachment arrangement for rotationally driving a lawn mower reel having a reel shaft comprising:
- a mower frame having two side portions,
- a first and a second bearing housing respectively mounted on said portions,
- the lawn mower reel having a shaft adapted to be rotatably supported on said bearing housings,
- a motor adapted to be operatively connected with said shaft for rotatably driving said shaft,
- a motor connection pin connected to said motor for fixedly securing said motor to said first bearing housing, and
- a first clamp located on said first bearing housing and releasably engaged with said motor connection pin for releasably attaching said motor to said first bearing housing.
A method of attaching a motor to a mower shaft bearing housing for rotationally driving the reel of a mower comprising the steps of
- securing a bearing housing on a frame of a reel mower for rotational support of said reel about its longitudinal axis of cutting rotation,
- positioning a driving motor along said longitudinal axis and providing a pin between said bearing housing and said motor for securing said motor to said bearing housing, and
- mounting a clamp onto said bearing housing for releasably clamping onto said pin and thereby secure said motor to said bearing housing.
