ABSTRACT:
A unitary-frame, straddle-type, crop-working vehicle with independent adjustability of straddle height, track width, and tool position is described. The vehicle features two lower tool-mounting arms and lateral and fore-and-aft adjustment to a center upper tool-mounting arm. Independent height adjustment of each of the vehicle's vertical mast structures facilitates upright hillside operation. Crawler tracks are utilized for ground travel and provide desirable weight distribution during crop-working operations.
