A shield assembly for a shaft includes a first tubular section having a first end and a second end and a second tubular section having a first end and a second end. The first and second tubular sections are each hollow receiving the shaft. The first tubular section includes a first outer diameter and the second tubular section includes a second outer diameter, the first outer diameter being greater than the second outer diameter. The first tubular section and the second tubular section are telescopically coupled to one another where the second tubular section is movably disposed at least partially within the first tubular section.

A cutter assembly includes a knife guard holder to be removably connected to a cutter bar, a knife guard and an interface between the knife guard holder and the knife guard. The knife guard may have a knife channel to slidably guide a cutter knife. The interface extends between the knife guard holder and the knife guard to locate and releasably retain the knife guard with respect to the knife guard holder.

A breakaway joint for a boom arm assembly includes a first boom segment defining a pivot axis at a first end, a second boom segment pivotally coupled to the first boom segment at the pivot axis, a bracket coupled to the first boom segment, a leaf spring coupled to the bracket between the first boom segment and the second boom segment, and a cam coupled to the second boom segment and positioned adjacent to the leaf spring. The first boom segment and the second boom segment are pivotally aligned in a neutral position. In the neutral position, the leaf spring contacts the cam at a first contact force, and in any position other than the neutral position, the leaf spring contacts the cam at a contact force greater than the first contact force.

An agricultural harvesting head includes a frame on which two endless belt side conveyors are mounted. The return run of the side conveyors is supported on long support strips surmounted by plastic wear strips that are mounted on top of support arms. The support arms extend forward from the rear of the frame to support a reciprocating knife mounted to the front of the agricultural harvesting head.

A twine delivery needle is constructed so as to include metal tip and mounting base sections or regions joined together by a relatively light weight central section having a composite structural sandwich construction comprising a low-density rigid foam core encased within a thin, high strength, skin or covering comprised of plies of woven and substantially continuous fibers disposed within a hardened matrix resin material.

Embodiments of a boom system for a work vehicle has a first boom member with a plurality of first boom segments aligned lengthwise to extend along a first boom dimension and a second boom member with a plurality of second boom segments aligned lengthwise to extend in the first boom dimension and spaced from the first boom member in a second boom dimension. The boom system also has a union spanning the second boom dimension to couple the first boom member to the second boom member and having a first coupling segment joining consecutive first boom sections together and a second coupling segment joining consecutive second boom sections together.

A unitary plastic chain guide for a row unit is provided including 2 blocks, one disposed at each end of the chain guide, and a wall extending therebetween to guide the chain.
