A protective enclosure or cab for an operator of a walk-behind or mechanical device, such as a snow blower, engine-driven snow thrower, ride-on tractor, or the like, is provided. The protective enclosure or cab includes an inflatable frame structure which supports a plurality of transparent, flexible windows or a single sheet of transparent material such as a curtain. When inflated, the protective cab is detachably coupled to the walk-behind or mechanical device and surrounds an operator of the walk-behind or mechanical device protecting the operator from the environment such wind, rain, snow or the like, while providing an unobstructed view of the surrounding environment. When deflated, the protective enclosure or cab can be folded into a small volume to be placed in a storage device which can be coupled to the walk-behind or mechanical device.

A cultivator including a housing structure, which can be fabricated from at least one injection molded part. A blade structure mounted thereto can be rotatably secured to opposing sides of the housing structure. The housing structure can include a gear housing structure which is configured to house at least one gear for enabling operation of the blade structure using a power tool and can be configured to provide increased rigidity to a corresponding side of the housing structure. An upper frame being a single-piece metallic structure having a horizontal and opposing vertical portions can be secured on opposing sides of the housing structure.

The disclosed technology relate to a device and system that include an outdoor power equipment power unit or cart configured to releasably couple a number of different interchangeable attachments or work implements to a common power unit, where some attachments include and/or require operator presence control, while other attachments do not include and/or require operator presence control. The outdoor power equipment power unit includes a power transfer coupling member operatively coupled to the drive shaft and configured to transfer rotational power to the associated attachment; and an operator presence actuation member operatively coupled to the operator presence control member, the operator presence actuation member configured to rotate in response to user actuation of the operator presence control member.

A gardening system includes a drive shaft operably coupled to first and second shafts for driving the first shaft in a first direction and the second shaft in a second direction. A first ground manipulation device is attached to the first shaft. A second ground manipulation device is attached to the second shaft.

A multi-functional garden implement comprises an underframe, and a power motor is secured to the underframe. The multi-functional garden implement also comprises an adapting tube, inside which a transmitting shaft is rotatably connected. One end of the transmitting shaft connects to a working head. A locking sleeve is secured to the underframe, and the end of the adapting tube movably inserts into the locking sleeve. There is a locking piece designed on the locking sleeve, which allows the locking sleeve to clamp the adapting tube and secure the adapting tube onto the locking sleeve. The present multi-functional garden implement can replace the working head quickly, so that it has functions of cutting, micro tilling, etc.

In one aspect, power equipment includes a cutter blade operation lever, a left rotary shaft, an operated member operated by the left rotary shaft to control driving of a cutter blade, and a releasable engagement mechanism provided between the left rotary shaft and the cutter blade operation lever. The releasable engagement mechanism is configured to release a force transmitting engagement between the cutter blade operation lever and the left rotary shaft to allow the cutter blade operation lever to rotate relative to the left rotary shaft when an excessive force is applied to the cutter blade operation lever in a direction to rotate the left rotary shaft beyond a normal rotational angle range.

In one aspect, electric power equipment includes: a horizontally extending left rotary shaft operably connected with a cutter blade operation lever; a horizontally extending right rotary shaft operably connected with a travel operation lever; and a cutter blade on/off switch and a potentiometer for setting a travel speed arranged at a laterally central position substantially between the left and right rotary shafts, such that the cutter blade on/off switch is operated by the left rotary shaft and the potentiometer is operated by the right rotary shaft.

A variable speed control system and method for a walk-behind working machine includes a control system base, a control lever selectively movable with respect to the control system base between two operating positions, a mode actuator positioned on the control system base for toggling between a plurality of control modes, and a control unit in communication with the control lever, the mode actuator, and a machine component. The control unit selectively controls the operation of the machine component between a minimum operating speed and a variable maximum operating speed. The control unit applies a different acceleration profile to accelerate from the minimum operating speed to the variable maximum operating speed depending on the control mode selected.

A rotary tiller comprises a frame, a cylindrical drum rotatable relative to the frame, a plurality of tines extending from the cylindrical drum, a motor at least partially disposed within the cylindrical drum, wherein the motor is configured to rotate a motor output member, and a transmission at least partially disposed within the cylindrical drum and configured to engage the motor output member. The transmission is operable to drive rotational movement of the cylindrical drum.

A tiller including a walking element configured to move the tiller, a tine rotatable about a rotational axis; a first motor configured to drive the walking clement to move the tiller, and a counterweight, wherein the tine is disposed on a first side of the tiller and wherein the counterweight is disposed on a second side of the tiller opposite the first side.
