A rear discharge mower unit ( ) with a mower housing ( ) defining grass clippings flow paths for directing grass clippings rearward. The mower unit includes a power transmission mechanism for rotating a center blade ( ) and a second side blade ( ) in one direction and a first side blade ( ) in the other direction, a center baffle ( ) extending around a rotational axis of the center blade and defining a center flow path ( ) for feeding grass clippings to a grass clippings outlet ( ), a first side baffle ( ) extending around a rotational axis of the first side blade ( ) and defining a first side flow path ( ) for feeding grass clippings to the grass clippings outlet ( ), and a second side baffle ( ) extending around a rotational axis of the second side blade ( ) and defining a second side flow path ( ) for feeding grass clippings to the center flow path ( ).

Rear discharge mower unit and lawn tractor

A mower unit (B) having a housing ( ), blades ( ) supported in the housing to be rotatable about vertical axes (P ) acting as the centers of rotation, cutting edges ( A) defined at front edge regions of each blade with respect to a direction of rotation thereof, and lift vanes ( B) erected from rear edge regions of each blade with respect to the direction of rotation thereof. Each of the lift vanes includes a first vane portion ( ) extending the more rearwardly, with respect to the direction of rotation, the farther away the first vane is from the center of rotation, and a second vane portion ( ) bent in the direction of rotation from a radially outward end of the first vane portion.

Mower unit

A rear discharge mower unit (50) with a mower housing (55) defining grass clippings flow paths for directing grass clippings rearward. The mower unit includes a power transmission mechanism for rotating a center blade (58) and a second side blade (60) in one direction and a first side blade (59) in the other direction, a center baffle (63) extending around a rotational axis of the center blade and defining a center flow path (69a) for feeding grass clippings to a grass clippings outlet (66), a first side baffle (64) extending around a rotational axis of the first side blade (59) and defining a first side flow path (69b) for feeding grass clippings to the grass clippings outlet (66), and a second side baffle (65) extending around a rotational axis of the second side blade (60) and defining a second side flow path (69c) for feeding grass clippings to the center flow path (69a).

A four wheel drive vehicle with dirigible front wheels, comprising a main propelling drive transmission, and a front wheel drive transmission connected to the main transmission. The front wheel drive transmission is switchable between a first four wheel drive mode in which the front wheels and the rear wheels are driven at a substantially equal peripheral speed and a second four wheel drive mode in which the front wheels are driven at a higher peripheral speed than the rear wheels. The front wheel drive transmission includes a piston operable by a hydraulic control system including a control valve mechanically interlocked to a steering section of the vehicle for switching the front wheel drive transmission from the first drive mode to the second drive mode. The piston, which normally is biased toward a position for the first drive mode, is movable against the biasing force to a position for the second drive mode when the front wheels are steered to an angle exceeding a predetermined angle.
