摘要： A gardening tool, such as a mower, has a main body having an accessory, such as a mowing blade, and a motor for driving the accessory. A handle is rotatably connected to the main body. At least one operation assembly is associated with the handle for being operated by a user to control the motor when the handle is located in a predetermined position. A control system prevents the motor from being controlled by the operation assembly and halts the motor when the handle is located out of the predetermined position.

摘要： A control system of a lawn mowing vehicle, includes at least one continuously variable transmission drivingly connected to two left and right wheels, a revolution speed detection unit, an acceleration instruction unit, a parking brake instruction sensor, a lawn mower, and a control device. The control device, during the drive of the lawn mower, stops the drive of the lawn mower after the revolution speed of each of the two wheels or the revolution speed of the at least one continuously variable transmission has become zero (0) or within a predetermined range near zero (0), and during stop control of the lawn mower, drives the lawn mower when a target revolution speed, issued by the acceleration instruction unit, of the two wheels or of the at least one continuously variable transmission is not zero (0) and the operation of the parking brake is not instructed.

摘要： Provided is a parking brake apparatus for a vehicle that allows an improvement in the ease of assembly during manufacturing. A parking brake apparatus for a work vehicle having wet brake mechanisms for restricting rotation of right and left axles and is able to simultaneously apply or release brakes via brake arms for the right and left transaxles. The parking brake apparatus includes a parking brake pedal for artificially providing a parking instruction, an electric actuator having a displacement portion that is displaced in response to the parking instruction, and a link mechanism connecting the displacement portion and the brake arms. The link mechanism includes auxiliary brake rods connected at first end portions to the brake arms, an equalizer connected to second end portions of the auxiliary brake rods, and a single principal brake rod connected at a first end portion to a substantially central portion of the equalizer and connected at a second end portion to the displacement portion.

摘要： Provided is a work vehicle capable of efficiently performing grass collecting work by decelerating a traveling machine body in a case where the size of a bale is large and a case where the pickup load of straw grass is large. The work vehicle includes a traveling machine body 1, a roll baler unit 2, a bale detection unit 31 configured to detect a size of the bale formed by the roll baler unit 2, a load detection unit 32 configured to detect a pickup load of straw grass in the roll baler unit 2, and a traveling control unit 17A capable of decelerating the traveling machine body 1 when a size of the bale is equal to or larger than a setting value B1 and when a pickup load is equal to or larger than a setting value L. A deceleration D2 is larger than a deceleration D1.

摘要： The disclosure relates to a braking system useful for providing stable braking of harvesters, such as self-propelled windrowers. The braking system utilizes respective service brakes associated with or integrated into a front drive system of the harvester, each of the service brakes configured to slow down or stop rotation of the respective front wheels. A controller/module is configured to receive inputs and feedback parameters to actuate components of the harvester to slow down or stop the harvester.

摘要： A brake apparatus for restricting rotation of a rotatable member of a mowing machine, thereby controlling rotation of a wheel of the mowing machine, includes a brake member fixable on the rotatable member, and a gripping member for engaging and disengaging the brake member for restricting or permitting rotation of the rotatable member. A thrust link is coupled to the gripping member such that movement of the thrust link causes the gripping member to engage or disengage a radially outer surface of the brake member. For example, the gripping member may be biasedly engaged with at least a partial circumferential extent of the brake member such that actuation of the thrust link causes disengagement of the gripping member from the brake member.

摘要： A braking system for a rotating chopper drum (14) of a forage harvester (10) driven from an engine (11) via a drive train including a disengageable clutch (21). The drive train also drives a first pump (28) connected with the drum (14) which pumps fluid around a hydraulic circuit which includes an openable restriction (40). The system is arranged to brake the chopper drum (14) by disengaging the clutch (21) and arranging the first pump (28) to pump fluid around the circuit via the openable restriction (40) as the drum (14) continues to rotate to convert the energy of the rotating drum (14) into heat.
