Brake modulators for parking brake systems of work vehicles are provided. A brake modulator includes a housing defining a fluid chamber, an auxiliary chamber, a fluid inlet channel, and a fluid outlet channel. The brake modulator further includes a piston disposed within the housing between the fluid chamber and the auxiliary chamber. The piston is movable between a first position wherein the fluid chamber has a first volume and a second position wherein the fluid chamber has a second volume greater than the first volume. The brake modulator further includes a biasing element providing a biasing force on the piston towards the first position, a rod extending between a first end disposed within the housing and a second end disposed exterior to the housing, and a handle connected to the second end of the rod. The rod is manually actuatable to move the piston between the first and second positions.

A system and method for brake assisted turning are provided. One system includes a pedal operated braking system configured to apply hydraulic brake pressure to brakes of a vehicle when one or more brake pedals are pressed. The system also includes a steer assist braking system configured to apply hydraulic brake pressure to the brakes of the vehicle based at least partly on a steering angle. The system includes hydraulic shut-off circuitry configured to selectively enable and disable operation of the steer assist braking system.

A drive system for an agricultural work vehicle. The drive system includes a front power takeoff device configured to extend from a front portion of the agricultural work vehicle and to be driven by an engine. The drive system also includes a first gearbox and a second gearbox positioned between the engine and the front power takeoff device. The first gearbox is configured to be driven by the engine and to provide power to drive the second gearbox. The second gearbox is configured to be driven by the first gearbox and to provide power to drive the front power takeoff device. The first gearbox and the second gearbox each provide a vertical shift between a respective driven input and a respective driving output.

A suspension system is provided that includes an axle configured to support a first wheel on a first lateral end of the axle, and a second wheel on a second lateral end of the axle. The suspension system also includes a steering assembly configured to rotate each wheel relative to the axle about a substantially vertical axis. In addition, the suspension system includes an actuating cylinder extending between the axle and a frame of a work vehicle. The actuating cylinder is configured to transition the frame between a lowered position that enables the steering assembly to rotate each wheel through a first range of motion without contact between the wheels and a component of the work vehicle, and a raised position that enables the steering assembly to rotate the wheels through a second range of motion, greater than the first range of motion.

Adjustable suspension system for a work vehicle

A clutch assembly for an agricultural work vehicle having a piston slidably disposed within a chamber having a first portion and a second portion. The piston is positionable between a first position and a second position in response to a fluid pressure within the first portion of the chamber to actuate a clutch mechanism. A sealing ring is associated with the piston to substantially prevent flow of fluid between the first portion and the second portion when the piston is in the first position. A bleed assembly is configured to permit flow of fluid between the first portion and the second portion when the piston is in the first position. The bleed assembly allows sufficient flow to substantially prevent unintentional engagement of the clutch mechanism.
