A turf cutting machine, more particularly a four-wheel drive turf cutting machine, is provided. The turf cutting machine has a transmission arrangement which includes a transmission belt arranged between a rear axle pulley and a front axle pulley and which further includes a plurality of deflection pulleys which are arranged between the rear axle pulley and the front axle pulley so as to define a path for the transmission belt that extends from a rear axle to a front axle and then back to the rear axle passing over a cutting blade.

A hydrostatic transmission includes a pump running surface and a motor running surface connected by internal porting formed in a housing member. A valve is disposed in the housing and connects a sump formed by the housing and the internal porting. A trunnion includes a first arm engaged to a swash plate to rotate the swash plate to vary the output of the pump, and a second arm which rotates with the first arm, the second arm having an operative end that is capable of opening the valve to permit a hydraulic connection between the internal porting and the sump through the valve bore when the trunnion is rotated to a predetermined position.

A lawn and garden tool having a handle, a tool head and an adjustable length boom, wherein the boom includes telescoping first and second boom sections. The tool includes a connector assembly having a lock adapted to selectively lock the boom sections relative to one another at any one of a plurality of telescopic locations. The connector assembly further includes a latch adapted to maintain engagement of the boom sections relative to one another, wherein the latch may be manipulated by an operator to selectively allow separation of the boom sections.

The present invention provides an embedded-outer rotor motor direct driven mower driving wheel and a mower. The embedded-outer rotor motor direct driven mower driving wheel comprises a driving wheel main body formed by the assembling of a wheel side cover I, a wheel side cover II, and a wheel body sandwiched between the wheel side cover I and the wheel side cover II, the wheel side cover I, the wheel side cover II and the wheel body are enclosed to define a cavity, an outer rotor motor is mounted in the cavity, an outer rotor portion of the outer rotor motor is fixedly arranged relative to the driving wheel main body, an internal stator portion of the outer rotor motor is provided with a fixed shaft penetrating through the wheel side cover I and extending out of the driving wheel main body, and the wheel side cover I is provided with a shaft hole I allowing the fixed shaft to penetrate through. The present invention arranges the outer rotor motor inside the driving wheel and directly drives the mower driving wheel through the outer rotor motor, thus, transmission precision and reliability are good, and the inner space of the mower is more reasonable.

An electric working machine with an operating rod includes an electric motor on the base end of the operating rod, a working device on the head end of the operating rod, and a power transmission shaft passing through the inside of the operating rod to transmit power from the electric motor to the working device. The working device includes a blade member and is pivotally supported on the head end of the operating rod to be able to take a storage posture. A detection switch on the head end of the operating rod detects the storage posture. A controller on the base end of the operating rod controls the operation of the electric motor. A lead wire in the operating rod transmits a detection signal from the detection switch to the controller. The controller prevents the electric motor from being driven when the detection switch detects the storage posture.

A working machine may include: a conversion mechanism configured to convert motion of a prime mover; a first blade connected to the conversion mechanism; a second blade overlapping with the first blade in an up-down direction and facing a first facing surface of the first blade; a sealing member engaged with a first non-facing surface of the first blade that is opposite to the first facing surface, wherein the sealing member includes a first sealing surface facing the first non-facing surface in the up-down direction; and a cover member facing a second sealing surface of the sealing member that is opposite to the first sealing surface of the sealing member. The sealing member may be disposed forward of the conversion mechanism and configured to suppress the object cut with the first blade and the second blade from moving toward the conversion mechanism between the first blade and the cover member.
