A detasseling apparatus includes a chassis having a head mounted to the chassis. The head supports a plurality of row units, each of the row units having an independently adjustable vertical position. Each row unit is independently vertically adjustable. Each row unit includes a puller or cutter, a height adjustment assembly for independently adjusting vertical position of the detasseling assembly to maintain the puller or cutter at a predetermined height relative to seed corn plants being engaged, and an optical sensing assembly. The optical sensing assembly includes a first photoelectric sensor at a first sensor height and a second photoelectric sensor at a second sensor height, the first sensor height being above the second sensor height. A processor receives and stores detasseling data related to detasseling including corn height, depth of cut, height after cutting. The information may be shown on displays to the operator, stored on board the detasseler and/or transmitted to a central control center.

A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear. The ground speed of the walk reel mower is automatically slowed during turns of the mower by a mechanical cable assembly that links a user operable throttle control and throttle reducing control to a prime mover throttle. Finally, the leverage provided by the mower handle assembly when placed in a lowered position is used by the user to more easily deploy a kickstand.

An agricultural apparatus including an agricultural vehicle together with a front work unit and two lateral work units located behind and to the sides of the front work unit. The front work unit has a connection to the front of the agricultural vehicle and the lateral work units share a connection to the rear of the agricultural vehicle. Each of the work units deposits a cut crop as a swath. One or more sensors determine a height of the deposited swath(es). A control unit controls a height of the connections above a ground surface such that if the height of one or more swathes is determined to exceed a predetermined value, the control unit causes the height of the rear connection to be raised.

A control system for an agricultural work vehicle is provided, the control system includes at least one controller, at least one control input device configured to send control signals to the at least one controller, and a header positioning assembly configured to interchangeably couple a plurality of headers to a chassis of a traction unit. The header positioning assembly is moveable between a plurality of orientations with each of the plurality of orientations providing a unique mechanical advantage. The at least one controller is configured to output a plurality of control commands corresponding to the control signals generated by the at least one control input device, and the control commands are configured to effect movement of the header positioning assembly between the plurality of orientations. An agricultural work vehicle is provided and includes the control system.

An adjustable lift rate system on a grass mowing machine such as a riding greensmower having a lift and lower circuit including a plurality of hydraulic lift cylinders to lift and lower a plurality of cutting units, and a controller providing a current to a proportional solenoid valve to bypass the hydraulic lift cylinders. An operator control may be used to adjust the current to the proportional solenoid valve to adjust the lift and lower rate of the cutting units.

A hydraulic leak detection system includes a leak detection switch responsive to a level of hydraulic fluid in a tank used by a hydraulic mowing circuit and a lift and lower circuit of a grass mowing machine. The system includes a controller that activates a warning indicator if the leak detection switch indicates the level of hydraulic fluid in the tank is low, but allows the hydraulic mowing circuit and the lift and lower circuit to continue operating until the lift and lower circuit reaches a fully raised position. A solenoid valve may control the level of hydraulic fluid in the tank based on temperature of the hydraulic fluid.

A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.
