An agricultural vehicle includes a frame, a body assembly coupled with the frame, a suspension system and a control system. The suspension system includes a pair of dampers positioned at opposite lateral ends of an axle. The suspension system includes a hydraulic system having a hydraulic line fluidly coupling the pair of dampers with each other through a valve. The valve is actuatable between an open position wherein the pair of dampers are fluidly coupled with each other, and a closed position in which the pair of dampers are hydraulically isolated from each other. The control system circuitry configured to obtain sensor feedback indicating a steering operation of the agricultural vehicle, and responsive to the steering operation of the agricultural vehicle, operate the valve into the closed position to hydraulically isolate the pair of dampers from each other to reduce a roll of the body assembly of the agricultural vehicle.

A steering system includes an arm, a knuckle, a joint, and a steering sensor. The arm defines a first passage. The knuckle has a knuckle arm defining a second passage. The joint has a ball portion and a shaft portion extending. The ball portion is disposed within the first passage and the shaft portion is disposed within the second passage. The ball portion defines a conical recess that has an opening at an upper end of the ball portion and terminates inside the ball portion with a pocket. The steering sensor has a driveshaft extending along a longitudinal axis into the conical recess. The driveshaft includes a head that engages with the pocket. The ball portion is configured to pivot within the first passage relative to the longitudinal axis and the head. The joint and the driveshaft are configured to rotate together about the longitudinal axis as the knuckle is turned.

A method and apparatus for mounting a pump stack in a self-propelled agricultural product applicator utilize a pump stack mounting arrangement including a pump stack, a crossmember with a web having an opening providing clearance for passage through the opening of at least one successive pump of the pump stack, and a removable mounting plate adapted for attachment to the crossmember and the at least one successive pump on an opposite side of the crossmember from a proximal end of the pump to provide support for a distal end of the pump stack. By removing the mounting plate, detaching any successive pump in the stack from its immediately preceding pump in the pump stack, and moving the detached part of the pump stack axially through the opening, clearance is provided for servicing a pump in the stack without removal of the whole pump stack or the crossmember.

A shear block mounting system secures a mounting plate of skid-mounted product application equipment to a frame of the applicator, utilizing a mounting bolt passing through a hole in the skid mounting plate, a mounting bar and a shear block. The shear block has a pilot that operatively engages a recess in the mounting bar in such a manner that shear forces are substantially transferred between the skid and frame substantially through the shear block pilot.

An exhaust after-treatment system has a DEF system with improved DEF purge cycling during which time DEF is returned to a DEF storage tank. The DEF system adapts its methodology based on a condition within the DEF system. A purge valve may be arranged in a doser feed line between a DEF supply module and a DEF doser module. A purging control system may be configured to control the purge valve based on detected states within the DEF system, such as a detected state that corresponds to a plugged DEF doser module. If a plugged doser module is detected, the purge valve may be opened to vent the doser module feed line to atmosphere which allows the DEF to be returned to the DEF storage tank without creating a siphon effect that could draw additional DEF from the DEF storage tank into the supply module.

A system, apparatus and method for providing task-specific ride-height control in a self-propelled agricultural product applicator utilize a controllable ride-height trailing arm suspension system for independently joining each wheel to a frame of the applicator. Each trailing arm suspension system includes upper and lower suspension arms, an extensible air strut, and an angular position sensor operatively interconnected to one another and disposed between a rolling axis of the ground engaging wheel independently supported by that suspension system and a point of attachment of the suspension system to the frame, such that the position sensor detects a relative angular position between the upper and lower suspension arms at a present extension of the air strut. An electronic control unit utilizes the angular positions detected by the sensors, in conjunction with a desired task input, to control the air struts in a manner providing a ride-height corresponding to the desired task input.

A system, apparatus and method for detecting and controlling the height of a frame of a self-propelled agricultural product applicator above a ground surface utilize a trailing link suspension system including an angular position sensor and extensible air strut, for connecting ground engaging wheels of the applicator to the frame of the applicator. Height of the applicator above the ground surface is determined by measuring relative angular rotation of upper and lower suspension arms of the suspension system about a suspension pivot axis, using the angular position sensor. Height is controlled by regulating a flow of pressurized air to the air strut, to thereby control extension of the air strut in a manner that controls a frame to axle, ride-height, distance of the suspension system.

A system, apparatus and method for providing task-specific ride-height and speed control in a self-propelled agricultural product applicator utilize a controllable ride-height trailing arm suspension system, including an extensible air strut and an angular position sensor, for independently joining each wheel to a frame of the applicator. An electronic control unit utilizes the angular positions detected by the sensors, in conjunction with a desired task input, to control the air struts in a manner providing a ride-height corresponding to the desired task input. The electronic control unit also controls maximum speed of the applicator for each task, per a predetermined schedule, or in response to a suspended load of the applicator.

A vehicle is shown such as a snowmobile, where a frame includes a tunnel and a front frame portion comprised of cast halves. A suspension system is comprised of upper and lower control arms connected to the front frame portion. Some of the frame components are adhesively fixed together. A powertrain is supported by the frame, and is comprised of an engine and a clutch. The clutch includes a clutch guard supporting an oil container. The engine has an exhaust system which extends through the front frame portion. The snowmobile also has a rear snow deflector.

Snowmobile

A snowmobile comprises a chassis with a front portion and a tunnel, and a power train unit supported by the chassis. The snowmobile further includes a plurality of ground-engaging members cooperating with the power train unit to operate the snowmobile. The plurality of ground-engaging members includes a pair of front skis and an endless track assembly. The snowmobile also includes a front suspension operably coupled to the pair of front skis. The front suspension includes a right control arm comprising a first right arm adhesively coupled to at least one right coupler, and a left control arm comprising a first left arm adhesively coupled to at least one left coupler. The first right arm and the left arm are comprised of a first material and the right and left couplers are comprised of a second material.
