Abstract: A sampling system and method are used for extracting a sample of dry product from a receptacle. An extraction tube having a perforated portion is disposed in a product storage volume of the receptacle. A pressurized air source is connected to a first end of the extraction tube. A sample collection device is located outside of the receptacle and serves to separate the sample from an airflow driven by the pressurized air source. An inlet of the sample collection device is connected to a second end of the extraction tube. A sample outlet is adapted to dispense the sample, and an air outlet is provided for venting pressurized air.

Abstract: An undercarriage assembly for a work machine including a drive wheel; front and rear idler wheels; an endless track belt about the drive and idler wheels; mid-rollers located between the front and rear idler wheels to engage the endless track belt; a track roller frame mounted on the machine at a main pivot, between front and rear ends of an elongate member, with the front idler wheel connected near the front end of the roller frame; a major bogie connected to the roller frame at a major bogie pivot, and the rear idler wheel connected to a trailing arm of the major bogie; a minor bogie, mounted on a forward arm of the major bogie, and pivotably connected to the major bogie at a minor bogie pivot, and including front and rear axles, supported by a suspension that provides damping between the front and rear axles and the minor bogie pivot.

Abstract: An apparatus having an accumulator fluidly coupled to a cylinder having a moveable rod and a pressure relief valve, the cylinder configured to produce an increase in resistance to retraction of the cylinder by re-routing fluid flow to the accumulator through the pressure relief valve after the rod has reached a defined retraction distance.

Abstract: An agricultural sprayer includes a mobile frame, a boom, and a boom-positioning mechanism. The boom is spaced from the frame. The boom-positioning mechanism is configured to support the boom on the frame for selective movement between a raised boom position and a lowered boom position. The boom-positioning mechanism includes a positioning actuator, and a telescoping parallel linkage providing constant spacing between the boom and the frame in the raised boom position and lowered boom position. The positioning actuator is configured to place the boom in the raised boom configuration upon elongation and in the lowered boom position upon retraction. The agricultural sprayer may further include a controller for positioning the boom relative to an underlying surface.

Abstract: An undercarriage assembly for a work machine including a drive wheel; a front idler wheel rotatable on a front axle; a rear idler wheel rotatable on a rear axle; an endless track belt about the drive and idler wheels; a number of mid-rollers located between the front and rear idler wheels to engage the endless track belt on a lower run; a track roller frame pivotably mounted on the work machine at a main pivot, including an elongate member with a front end and a rear end with the main pivot located between the front end and the rear end and the front idler wheel connected near the front end of the track roller frame; a major bogie including forward and trailing bogie arms, the major bogie pivotably connected to the track roller frame at a major bogie pivot, and the rear idler wheel connected to the trailing bogie arm; a minor bogie, mounted on the forward bogie arm, the minor bogie pivotably connected to the major bogie at a minor bogie pivot, and including a minor bogie suspension, a minor bogie front axle,

Abstract: A working vehicle has a ballast weight system including a fulcrum mounted on the vehicle frame and a ballast weight configured to pivot between a mounting configuration with the ballast weight is resting on the ground and an operational configuration with the ballast weight is carried by the vehicle frame. The ballast weight has a mounting arm and a lower corner portion. The mounting arm has a recess configured to interact with the fulcrum, wherein in the mounting configuration, the recess faces sideways such that the work vehicle is driven towards the ballast weight until the fulcrum interfaces with the recess. A catch mechanism secures the ballast weight to the fulcrum. A lift mechanism attaches between the ballast weight and the vehicle frame such that the lift mechanism pushes on the corner portion to pivot the ballast weight about the fulcrum. A latch mechanism pins the ballast weight in the operational position.
