Abstract:

A relief grinding device (100) is disclosed including a flange assembly (106) slideably mounted on and rotatable with a grinding shaft (18) which is mounted on the free ends of pivot arms (14) pivotally mounted to a table (12). A grinding wheel (108) is mounted to and rotatable with the flange assembly (106). A back relief housing (114) is rotatably mounted to the flange assembly (106) and held at an adjustable angle on the grinding shaft (18) by a back relief restraint (124) adjustably secured thereto and slideable on a support shaft (102). A stop (134) for abutting with the first face of the blade is mounted to a holder (128) slideably mounted to a mount (122) of the back relief housing (114). A guide finger (138) for abutting with the opposite face of the blade is slideably mounted to the holder (128) and a holding block (136) secured to the stop (134). The blade freely passes between the stop (134) and the guide finger (138) which maintain the position and orientation of the blade relative to the grinding wheel (108) grinding a relief grind on the radially outer edge of the blade.

Abstract:

A variable tie-rod assembly for a steering wheel structure of a row crop applicator. The tie-rod assembly can be adjusted and secured in any position between a minimum and maximum track setting. Thus, a selectively variable track width is provided. Toe-in settings are maintained by implementing a dual-cam arrangement with a locking pin to maintain the steering structure in a forward direction during track width adjustment procedures. The track width setting can be adjusted without the operator ever having to leave the cab of the row crop applicator, wherein the track width can be visually ascertained by observing indicia on the telescoping wheel structure.
