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.

Method and system for obtaining a sample of dry product from a receptacle

A sprayer vehicle 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 raise the boom to the raised boom position upon elongation and to lower the boom to the lowered boom position upon retraction. The agricultural sprayer may further include a controller for positioning the boom relative to the frame, an underlying surface, or another reference.

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.

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.

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.

Self mounting ballast weight system

A drawbar pin-retention assembly for use with a drawbar mechanism has a swinging drawbar, a support housing, and a device configured to prevent the swinging of the drawbar, the device having at least one drawbar pin. The pin-retention assembly includes a hanger bracket having a body portion and a pair of overhanging arms and a retaining bracket mounted on the hanger bracket with hinge tabs and pivotable about a pivot axis to move between a pin-retaining position and a pin-removal position. When the retaining bracket is pivoted to its pin-retaining position, a strap is positioned over the drawbar pin. Outward movement of the pin causes it to contact a forward portion of the strap forward of the pivot axis causing the retaining bracket to contact the hanger bracket thereby preventing pivoting of the retaining bracket in a first direction. The retaining bracket pivots by gravity to the pin-retention position.
