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 powered hand tool is adapted to use a variety of interchangeable rotary tools to assist in outdoor activities. Either of two basic tool designs can be utilized for activities including garden tilling, brushing and cleaning, auguring or post hole digging, and auto finishing and polishing. In one embodiment, an adjustable shroud is utilized along with a tiller construction to change the viewing angle of the working tiller tines to facilitate use by operators of different heights, including a kneeling position. The ability to utilize tow torque and low speed assists in avoiding accidental damage to underground wires and, if encountered, the reversibility of the drive assists in untangling the wires.

A facility agricultural laser measure and control motor rotary tillage flattening machine includes a front axle part, a lifting equipment, a rotary tillage component, a battery pack, a rear axle steering part, a rotary flattening component and a rack. A front axle housing with the rack. The rotary tillage component comprises a DC motor, a gearbox and a rotary tillage blade. The DC motor connects with the gearbox through transmission. An output shaft of the gearbox connects with the rotary tillage blade. The rear axle steering part includes a rotary seat, a rotary shaft, a steering handlebar, a rear axle stand and squirrel-cage hubs. An upper end of the rotary shaft is equipped with a steering handlebar. The rear axle stand is equipped with two squirrel-cage hubs through a supporting axle. The rotary flattening component connects with the rack through an electromotive handspike and a flexible torsion bar.

The present subject matter relates to adjustable ground speed control devices, systems, and methods for walk-behind equipment. A variable speed control system may include a control system base, a control lever selectively movable with respect to the control system base between a first operating position and a second operating position, a mode actuator positioned on the control system base for toggling between a standard mode and a selection mode, and an adjustment actuator positioned on the control system base in communication with a control unit to toggle between a first control mode and a second control mode when the mode actuator is in selection mode. The control unit applies a first acceleration profile to accelerate from the minimum operating speed to the variable maximum operating speed when in the first control mode and a second acceleration profile when in the second control mode.

A ground treatment device including a housing fabricated from at least one injection molded part. An axle with a ground treatment attachment mounted thereto can be rotatably secured to opposing sides of the housing. The housing can include a gear housing structure which is configured to house gears for enabling operation of the ground treatment attachment using a power tool. An upper frame can be secured to opposing sides of the housing. The ground treatment attachment can be configured to cultivate the ground.
