Abstract: A tree shear attachment is, in one preferred embodiment, designed to replace the shovel at the outermost end of the boom assembly of a backhoe to provide remarkable maneuverability and an extensive range of motion for the shear. One of the severing jaws is fixed, presenting a stationary anvil, while the other is moveable and is provided with a shear blade that moves into engagement with the stationary anvil to complete the severance. Retainers at the forwardmost ends of the jaws help grip and stabilize the butt end of the tree following severance. An upstanding stabilizing rack on the frame of the shear has a pair of laterally spaced, forwardly projecting arms that generally overlie the two jaws to embrace and stabilize upper portions of the tree during and after severance.

Abstract: An improved apparatus (62) for on-the-go lateral adjusting of a field implement (10) is provided, and is especially useful for a pull-behind, tractor-mounted implement (10) designed to operate on or between rows (30) of a crop (32). The apparatus (62) includes a sensing assembly (64) having lowermost feelers (70, 72) designed to detect the position of the implement (10) relative to generally parallel crop rows (30), along with implement adjusting structure (66) and a hydraulic control assembly (68). The adjusting structure (66) is preferably in the form of a piston and cylinder assembly (104) pivotally coupled between the draw bar (14) of a tractor (12) and one of the three point hitch arms (16) thereof. The control assembly (68) is in the form of a solenoid-operated hydraulic valve (128) interposed between the hydraulic system of the tractor (12) and the cylinder (106) of piston/cylinder assembly (104).
