LAWN MOWER
A lawn mower includes a housing having an opened bottom, a drive source for driving the cutter blade in the housing, a flap provided for the cutter blade in a manner that the flap has a changeable flap angle, a grass clippings container storing cut lawn grass, a grass clippings container weight detection unit for detecting weight of the grass clippings container, and a control unit. The control unit controls at least one of the rotational speed of the drive source and the flap angle of the flap in correspondence with the weight detected by the grass clippings container weight detection unit.
Zero turn radius mower with cutting blade control
A zero turn radius mower including a pair of rear drive wheels, a mowing deck including multiple cutting blades, an electric storage battery, a pair of electric wheel motors each operable to rotate one of the rear drive wheels, multiple electric blade motors each operable to rotate one of the multiple cutting blades, and a master controller in communication with each of the pair of wheel motors and the multiple blade motors. The master controller is operable to control a rotational speed of each of the pair of wheel motors and the multiple blade motors. The master controller is operable to stop rotation of the cutting blades when the wheel motors are operating below a threshold speed.
Vegetation cutting device
A vegetation cutting device comprises: a housing; a motor mounted in the housing having a rotatable drive shaft; a gearing system comprising a rotatable output shaft, the gearing system adapted to be driven by the drive shaft; a rotatable cuffing head mounted on the output shaft; a rotation sensor module mounted in the housing and configured to detect the rotational speed of the motor and configured to output a rotational speed signal; and a control module configured to determine the rotational speed of the cutting head based on the rotational speed signal and configured to control the speed of the motor in response to the determined rotational speed of the cutting head.
RIDING MOWER
A riding mower includes a seat for a user to sit on, a main frame configured to support the seat, a power output assembly configured to mow vegetation, a traveling assembly configured to enable the riding mower to travel, an operating assembly configured to be operated by the user, a control module configured to control the riding mower, and a power supply apparatus configured to supply power to the riding mower. At least a portion of the control module is disposed on the lower side of the seat, and the control module comprises a drive control board for controlling the power output assembly and the traveling assembly, a fuse, and a power supply management module.
Electric drive system for a mower
An example vehicle comprises: (i) at least one electric generator that can be electronically-commutated or passively rectified, (ii) at least one electronically-commutated electric motor configured to drive a wheel of the vehicle, (iii) a voltage bus connecting the electric generator with the electronically-commutated electric motor, and (iv) means of controlling voltage level of the voltage bus.
Zero turn radius vehicle with single steered wheel
A zero turn radius vehicle with a single steered wheel is described. The vehicle may include a pair of power transfer mechanisms driving a pair of wheels, an operator control mechanism for controlling the steering, speed and direction of the vehicle and a controller in communication with the operator control mechanism. A steerable wheel is located adjacent the front of the vehicle frame, on a first side of the vehicle frame and an electric actuator is connected to the controller for steering the front steerable wheel. A second, non-steerable front caster wheel is located on a second side of the vehicle frame. The controller controls the pair of power transfer mechanisms and the electric actuator based on operator input to the operator control mechanism.
Agricultural vehicle with adjustable lift height based on header identification
An agricultural vehicle includes a chassis (16), a lift arm (18) movably coupled to the chassis (16), a lift actuator (21) coupled to the lift arm (18), a header (14) coupled to the lift arm (18), and a controller (120) operably coupled to the lift actuator (21). The controller (120) is configured to: receive a header type signal corresponding to a header type of the header; define a lift height limit of the header based at least partially on the received header type signal, the lift height limit being a first height limit when a first header type signal is received or a second height limit when a second header type signal is received; and output a lift signal to the lift actuator (21) to vertically displace the header (14). Header vertical displacement is limited to the first height limit if the first header type signal is received or the second height limit if the second header type signal is received.
Operation safety assembly for a lawncare apparatus
A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved.
WALK BEHIND MOWER
In a walk behind mower (10) including a clutch (23) provided in a power transmission path between an electric motor (35) and driven wheels (13), a clutch actuating mechanism (24) interposed between the electric motor and the clutch for selectively engaging the clutch, and a control unit (140) for selectively supplying electric power from a power source to the electric motor according to a command from an operation switch (30), the clutch actuating mechanism includes a cam mechanism for engaging the clutch by using a force transmitted to an input end (23a) of the clutch in the power transmission path when the electric motor is being driven in a normal rotational direction, and the control unit is configured to drive the electric motor in a reverse rotational direction for a prescribed period of time before stopping supplying electric power to the electric motor when a command to stop supplying electric power to the electric motor is received from the operation switch.
POWER EQUIPMENT WITH CYLINDER DEACTIVATION ENGINE
The power equipment such as a lawn mower (10) comprises an internal combustion engine (100) having a plurality of cylinders, an engine control unit (110) for selectively deactivating at least one of the cylinders, a work implement such as a cutting blade (70) connected to the engine in a power transmitting relationship, a clutch (80) provided in a power transmission path between the engine and the work implement, and a central control unit (50) for controlling an operation of a propelling device, the clutch and the engine control unit. The central control unit is configured to operate the engine at a prescribed rotational speed with two or more of the cylinders kept activated when the clutch is engaged and the propelling device is propelling the power equipment forward, and to deactivate at least one of the cylinders when an opening of a throttle valve is below a first prescribed value for a prescribed time period.
