11/522395

Inventors:

Jason M. Simmons - Platteville WI, US
Donald R. Flatau - Sherwood Park, CA

Assignee:

DEERE & COMPANY - Moline IL

International Classification:

E02F 9/28

US Classification:

37453

Abstract:

Bucket teeth having a metallurgically bonded wear-resistant coating and methods for forming the coated bucket teeth are disclosed. The bodies of the bucket teeth have a hard metal alloy slurry disposed on a surface and then are fused to form a metallurgical bond with the iron-based alloy. The wear-resistant coating can be formed of a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof. The portion of the outer surface of the bucket teeth having the wear-resistant coating corresponds to a wear surface of the bucket teeth during operation.

International Classification:

E02F 3/36

Abstract:

A quick coupler primary lock arrangement includes a fore-and-aft guided wedge arrangement carried by a cross shaft and is biased forwardly to a lock position by a first spring arrangement, and includes a secondary lock arrangement includes a locking pawl arrangement pivotally mounted to the cross shaft and biased, by a second spring arrangement, to a secondary lock position wherein the pawl arrangement includes a surface disposed in a confronting locking disposition relative to an abutment surface of a fixed plate of the coupler to thereby prevent rearward movement of the wedge arrangement from the lock position. A normally depressurized hydraulic cylinder is coupled to the pawl arrangement and when selectively pressurized overcomes spring biasing forces and pivots the pawl arrangment from the secondary locking position and then shifts the wedge arrangement rearward to a coupler release position. An electro-hydraulic control arrangement prevents unintentional operation of the hydraulic cylinder.
