A lawn mower includes a mower device provided between a pair of right and left front wheels and a pair of right and left rear wheels and configured to mow grass on a traveling land surface; a grass collecting container provided rearwardly of a vehicle body, a conveyer duct extending between the mower device and the grass collecting container as extending through between the pair of right and left rear wheels and configured to convey grass clippings discharged from the mower device to the grass collecting container; and a belt conveyer configured to convey the grass clippings discharged from the mower device toward the grass collecting container. The belt conveyer forms a conveying bottom face of the conveyer duct.

Harvesting apparatus (10), namely merger or pickup swather with pickup members (18) designed as pickups for picking up harvested crop, with at least one transverse conveyor device (19) designed as belt conveyor for conveying the picked-up harvested crop in a transverse conveying direction running transversely with respect to a harvesting direction or direction of travel, wherein each pickup member (18) designed as a pickup is mounted pivotably on a respective transverse conveyor device (19) designed as belt conveyor, namely centrally with respect to the respective pickup member (18) via a respective joint (22).

A walk power mower has a deck that provides a cutting chamber for enclosing a rotary grass cutting blade. An assembly is provided for adding ambient air to the cutting chamber during a grass mowing operation to improve performance. The assembly comprises an air vent placed in a top wall of the cutting chamber. An external cover outside of the cutting chamber and above the top wall of the cutting chamber has an air permeable section located forwardly of the air vent to admit air into the cover to thereby feed that air to the air vent. An internal cover inside the cutting chamber and below the top wall of the cutting chamber receives the air passing inwardly through the air vent and discharges such air into the cutting chamber at a location that is spaced from the air vent.

A mower combination including an agricultural vehicle and a front mowing unit as well as two lateral mowing units located behind and to the sides of the front mowing unit. Each of the lateral mowing units has a conveyor unit to deposit cut crop as a swath. A control unit receiving a plurality of signals from the combination including signals representing a steering angle of the agricultural vehicle, a speed of operation of each conveyor unit and a lateral displacement of each conveyor unit and comparing them against a predetermined set of values. As required the control unit adjusts the speed of operation of at least one conveyor unit based on this comparison. Swaths produced by towed rear mowing units are controlled, in particular to enable aligned curved swaths to be produced when the mower combination is turned, or to enable a narrow swath to be produced when the mower combination is turned.

A mower combination having an agricultural vehicle and a number of mowing units suitable for cutting a standing crop connected to the agricultural vehicle, including a front mowing unit and two lateral mowing units located behind and to the sides of the front mowing unit, each of the lateral mowing units being provided with conveyor units to deposit cut crop as a swath. A control unit receives a plurality of signals, representing the location of the mower combination, a displacement of each of the conveyor units and/or a direction of operation of each of the conveyor units. The control unit receives the plurality of signals and compares them against a predetermined set of values and as required adjusts the displacement or direction of operation of at least one conveyor unit based on this comparison.

A grass mower includes a blade shaft for rotating a blade within a mower deck supported to a vehicle body, a power transmission mechanism for supplying rotational power to the blade shaft, a duct for air-conveying cut grass pieces from the mower deck to the grass collecting bag and a flow boosting device incorporated in the duct. The flow boosting device increases a speed of air flow inside the duct by feeding air through a nozzle opening adjacent an inner circumferential face of the duct along a flow direction of the air flow.
