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, an operating arm connected to the first end of the main body, and a transmission assembly. The transmission assembly is configured to prevent the switching device from being controlled in a mechanical way by the operation assembly or/and turning on the motor when the first member is moved towards the main body to a predetermined position relative to the second member.

A torque limiter assembly and/or damage mitigation assembly that can limit torque and other forces from being applied to a motor or motor assembly of a lawn maintenance device such as a mower. For example, sudden blade-stop events or other events that might damage the motor can instead be absorbed or dispersed by the torque limiter assembly via use of a friction material. The torque limiter assembly can have a shaft and bearings that are independent of the motor shaft and motor bearings. The friction material can serve as a mechanical linkage between the two independent shafts operating to limit torque exchanges between the two shafts that exceed a defined magnitude. In the event that wear or damage is sustained, such will tend to be limited to the torque limiter assembly, which can be repaired or replaced in a more cost effective or simplified manner than the motor assembly.

A method of stacking dethatchers includes pivoting an upper portion of a handle on a first dethatcher toward a front end of a frame on the first dethatcher, upon pivoting the upper portion of the handle toward the front end of the frame, exposing a rear support point defined by a lower portion of the handle, and stacking a second dethatcher on the first dethatcher so that the second dethatcher is supported on the rear support point defined by the lower portion of the handle and a front support point defined by the upper portion of the handle.

An agricultural vehicle with a header including multiple row units each include a feed/snapping unit and a chopping unit. The header further includes a first power transmission shaft for driving the feed/snapping units, and a second power transmission shaft connected via a drivetrain to a drive at the agricultural vehicle. Each chopper unit includes a safety clutch and is connected via the safety clutch to the second power transmission shaft. At least one torque sensor is provided for the second power transmission shaft, drivetrain, or drive, which torque sensor is operationally connected to a torque fluctuation monitor configured to recognize a predetermined change in torque fluctuation indicating a safety clutch slip. The torque fluctuation monitor is operationally connected to a user interface for signaling the safety clutch slip.

A conveyor and conveyor drive for filling a combine grain tank includes a chain and paddle conveyor in a housing (114) that feeds an intermediate chamber (116), a gearbox with a first coupling element (208), the first coupling element (208) having teeth (230) with holes therethrough to permit the expulsion of grain from between the first coupling element (208) and a second coupling element (210) that is connected to a pivoting auger conveyor (104).

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.
