摘要:
A cutting system for a harvester, the cutting system including a knockdown roller, at least two row dividers, at least two base cutting elements, and at least two inner base cutting discs. Each of the at least two base cutting elements is disposed in the structure of a respective one of the at least two row dividers. Each of the at least two inner base cutting discs is disposed behind the knockdown roller. The cutting system further includes two arms and a lifter roller. Each of the two base cutting elements is connected to a respective one of the two row dividers by a respective one of the two arms. Each of the two base cutting elements is positioned entirely forward of the knockdown roller and the lifter roller.

An electric mower includes a chassis; and a walking device, a mowing device, a power device, a handle device, and a back grass discharging device arranged on the chassis. The power device drives the operation of the walking device and the mowing device, the back grass discharging device discharges the grass cut by the mowing device, and the handle device controls the electric mower. The power device of the electric mower uses a hybrid power system formed by DC power supply and AC power supply.

The present invention provides a riding work vehicle that includes a vehicle body having a driver seat; a driving wheel unit supporting the vehicle body; a working electric motor that drives a work unit having a work device; an electric motor controller controlling an operation of the working electric motor in a steady mode or a power saving mode in which consumed power is smaller than the steady mode; and a work load evaluator that evaluates load of the working electric motor. In the riding work vehicle, the electric motor controller operates the working electric motor in the power saving mode in a case where the load of the working electric motor evaluated by the work load evaluator is low load lower than a threshold value.

An electric grasscutter includes a motor (50) which drives a rotary blade (42). The motor (50) is a brushless motor accommodated in a motor housing (51) and including a rotor (53) provided integrally with an output shaft (52), and a stator (54) fixed to the motor housing (51). A motor control circuit which drives the motor (50) is accommodated in the motor housing (51). The motor control circuit includes an inverter having FETs (81-86) as switching elements, and a control section to control the FETs (81-86). The FETs (81-86) are fixed in contact with the motor housing (51).
摘要:
A riding mower including two mower blades that rotate to mow grass and generate air flows, the two mower blades including a left mower blade and a right mower blade, a mower deck, two motors that rotate the respective mower blades and a controller is provided. The left and right mower blades being provided adjacent to each other and one of the left and right mower blades being disposed obliquely in front of the other mower blade. The riding mower generates a combined air flow and discharges mowed grass to the outside of the mower deck together with the combined air flow. The controller controls such that a difference between the rotational speeds of the left and right mower blades is changed at a predetermined period and the mowed grass is discharged to the rear of the mower deck uniformly in a lateral direction of the mower deck.

An electric motor-driven rotary disc cutter module for use in a cutterbar in an agricultural harvester. In one embodiment, each rotary disc module includes an electric motor driver for the rotary cutterhead. Individual cutterhead modules are staggered fore and aft along the cutterbar to provide continuous cutting across the lateral width of the cutterbar without requiring synchronized rotation of the cutterheads to prevent contact of the knives. This configuration allows for individual speed and/or rotational direction adjustment for each cutterhead to optimize crop cutting performance and/or crop movement within the header. A control system may be included to monitor performance and manage individual operation of the cutterhead modules.

Provided is a mobile electric work machine that can avoid overload operation of working parts. The mobile electric work machine is an electric lawn mowing work machine that carries out work by working parts driven by electric power supplied by blade inverters while being run by a running part. The blade rotational velocity of a blade or the rotational velocity of a blade is controlled such that the work load on the working parts is constant on the basis of blade inverter current values from blade inverters.
