A drive pulley for a continuously variable transmission (CVT) has a pulley shaft with a fixed sheave, a movable sheave and a back plate thereon. The movable sheave has a movable sheave surface with first and second surface portions that faces the back plate. A biasing member biases the sheaves away from each other. A slider is disposed between the back plate and the movable sheave. The slider has a flat engagement zone surface, and a curved driving zone surface extending outward from the engagement zone surface. From rest, as the pulley shaft accelerates, the engagement zone surface of the slider slides radially outward against the first portion of the movable sheave surface and then the driving zone surface of the slider slides radially outward against the second portion of the movable sheave thereby pushing the movable sheave toward the fixed sheave. A vehicle having the CVT is also disclosed.

A four-wheeled vehicle includes: a frame; two front suspension assemblies and two rear suspension assemblies connected to the frame; two front wheels operatively connected to corresponding ones of the two front suspension assemblies; two rear wheels operatively connected to corresponding ones of the two rear suspension assemblies; a motor connected to the frame; a front differential and a rear differential operatively connecting the motor to the two front wheels and the two rear wheels respectively; and a steering system. The steering system includes a front steering assembly for steering the front wheels and a rear steering assembly for steering the rear wheels. The front steering assembly includes a user-operated steering input device. The rear steering assembly includes an actuator operatively connected to the rear wheels and operable to modify a steering angle thereof. The actuator is mounted to the frame and is disposed completely rearward of the rear differential.

An engine mounting system for a work vehicle includes an engine mount configured to support an engine on a frame of the work vehicle. The engine mount has an engine mounting portion and a frame connection portion, an extent of the frame connection portion along a lateral axis of the engine mount is greater than an extent of the engine mounting portion along the lateral axis, the engine mounting portion has an opening configured to receive a fastener configured to couple the engine to the engine mount, the frame connection portion has a substantially flat contact surface configured to engage a corresponding substantially flat contact surface of a frame member of the frame, and the engine mounting portion does not contact the frame member while the substantially flat contact surface of the frame connection portion is engaged with the corresponding substantially flat contact surface of the frame member.

A machine control system controls operation of any one of a plurality of interchangeable power sources mounted on a machine. The machine includes an undercarriage supporting ground engagement members that propel the machine and an upper structure rotatably supported on the undercarriage. The upper structure includes a swing frame that supports an operator cab, an interchangeable power source, hydraulic components, and electrical components. A processor processes inputs, outputs and operating characteristics specific to each of the plurality of power sources, and standardizes the power output by each of the power sources to provide a normalized, consistent control and operation of systems of the machine regardless of which of the power sources is mounted on the machine.

The invention relates to a powertrain for a vehicle. The powertrain comprising: at least one propulsion unit; a transmission connected to the at least one propulsion unit; a propeller shaft connected to the transmission, and at least one drive shaft of a rear axle, which at least one drive shaft is connected to the propeller shaft, so that the propeller shaft extends between the transmission and the at least one drive shaft. The at least one propulsion unit is arranged in a position between the transmission and the rear axle in a longitudinal direction of the vehicle. The invention also relates to a vehicle.

A utility vehicle includes: a vehicle body frame including a cabin frame portion; a loading bed tiltable between a normal position and a dumping position; and an intake unit including an intake port. The intake unit is disposed above a rear wheel and extends over a height range overlapping a height range over which the loading bed in the normal position extends, and a location of the intake unit in a vehicle width direction substantially coincides with a location of a side wall portion of the loading bed in the vehicle width direction. The intake unit is located rearward of the cabin frame portion and exposed to the outside in the vehicle width direction. The intake unit is fixed to the vehicle body frame at a distance from a trajectory along which the loading bed is tilted.
