Undercarriage assembly components of track-type machines having a metallurgically bonded wear-resistant coating and methods for forming such coated undercarriage assembly components is taught herein. The bodies of the undercarriage assembly components, formed of an iron-based alloy, have a hard metal alloy slurry disposed on a surface or into an undercut or channel and then fused to form a metallurgical bond with the iron-based alloy. The wear-resistant coating comprises a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof. The portion of the outer surface of the undercarriage assembly components having the wear-resistant coating corresponds to a wear surface of the component during operation of the endless track of the track-type vehicle.

Mechanical face seal rings having a metallurgically bonded wear-resistant coating on the wear surfaces thereof and methods for forming such coated components is taught herein. The face seal rings, which can be formed of a relatively inexpensive base metal or alloy, have a hard metal alloy slurry disposed on the wear surfaces and then fused to form a metallurgical bond with the iron-based alloy. The wear-resistant coating comprises a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof.

A track chain assembly for a crawler type work vehicle includes a plurality of links pivotally connected together at respective link joints. Each link joint includes a bushing, a pin, and at least one elastomeric bearing. Each elastomeric bearing includes an inside diameter (ID) engaging the pin and an outside diameter (OD) engaging a link and/or bushing. Each elastomeric bearing includes a plurality of alternating metal layers and elastomer layers.

An undercarriage is disclosed that includes a rigidly mounted track roller near or adjacent to a rear drive sprocket, with the outer radius of the track roller overlapping the outer radius of the drive sprocket. The remaining rollers and bogies may be flexibly suspended.

Undercarriage assembly components of track-type machines having a PTA welded wear-resistant coating and methods for forming such coated undercarriage assembly components are disclosed. Bodies of the undercarriage assembly components, formed of an iron-based alloy, have a material PTA welded on a surface or into an undercut or channel of the iron-based alloy. A heat treatment of the formed component further hardens the body. The portion of the outer surface of the undercarriage assembly components having the wear-resistant coating corresponds to a wear surface of the component during operation of the endless track of the track-type vehicle.

A sprocket has a base steel member including an outer toothed profile surface, at least a portion of the outer toothed profile surface having a wear and corrosion resistant coating disposed thereon; the coating comprising an alloy, the alloy comprising at least 60 weight % iron, cobalt, nickel, or alloys thereof. A method of producing a wear and corrosion resistant sprocket includes: (i) machining a base steel member to form an outer toothed profile surface thereon; (ii) applying a coating to at least a portion of the surface; and (iii) fusing the coating to the base steel member.

A track pin bushing for cooperating with a track pin in an endless track has a tubular body with a metallurgically bonded wear-resistant coating and a method for forming such a coated track pin bushing is taught herein. The tubular body, formed of an iron-based alloy, has an outer surface that is carburized and quenched, i.e., case-hardened, in at least a section thereof. At least a portion of the case hardened section has been removed to a depth sufficient to expose a non-carburized layer of the iron-based alloy. A hard metal alloy slurry is disposed on the non-carburized layer and forms a metallurgical bond between the non-carburized layer and the coated unfused slurry by fusing the hard metal alloy. The thickness of the unfused slurry is adjusted to be from 1.67 to 2.0 times a final thickness of the wear-resistant coating. The wear-resistant coating comprises a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof. The portion of the outer surface with the wear-resistant coating corresponds to a contact surface adapted to engage with a drive sprocket in the endless track of the track-type vehicle.

A two piece seed boot for a seeding machine has a upper cast portion and a lower cast portion. Both the upper and lower portions are provided with aligned seed passages which received metered seed from the seed tube and discharge the metered seed to the planting furrow. The upper cast portion is mounted to the planting unit frame and the seed tube by an integral mounting clevis. The lower cast portion is provided with first and second upward extending mounting lugs. The first mounting lug is received in a recess formed in the upper portion. The second mounting lug engages the planting furrow side of the upper portion. The rear of the upper and lower portions are provided with aligned mounting holes through which a mounting bolt passes securing the lower portion to the upper portion.

An opener for use in varying ground conditions, ranging from no-till to conventional full tillage conditions, includes an adjustable down pressure control and a down pressure spring and tension link assembly which selectively provide a limited free float opener condition or a conventional down pressure spring controlled bias condition. A sleeve slidably received by the opener arm and mounted over the lower portion of the tension link assembly allows the opener to free float in loose soil conditions so that only the weight of the opener provides downward bias when the down pressure control is adjusted to a minimum condition. The opener is free to ride up and down to follow irregularities in the ground surface. In harder soil conditions such as those encountered in no-till farming methods, the down pressure control is adjusted to a position wherein an enlarged portion on the sleeve bottoms against the opener arm and the spring begins to compress so that the opener operates in the conventional spring biased mode. The sleeve allows increased downward movement of the opener to follow depressions in the soil.
