A tractor for over the row in line towing of a trailer along a row of plants, wherein either the trailer or the tractor itself has the capability of carrying mechanisms for performing certain operations on a row crop. Such mechanisms include crop harvesters, plant pruners, plant sprayers or device for tilling the ground adjacent the plant rows. Use of these mechanisms in sloping fields is specifically envisioned. A portion of the tractor is designed to carry these mechanisms and is maintained in a level configuration in fields of row crops without substantial elevation of the tractor center of gravity. The main elements of the tractor are kept near ground level for easy access in all types of row crop terrain, sloping or otherwise, so that fueling and maintenance tasks may be readily performed and ground access to an operator's station is always available.

[ What is claimed:] [1.] A tractor having a substantially constant center of gravity over an underlying surface during lateral leveling and being configured for running on the underlying surface and over a row of plants in a plurality of plant rows carrying a crop to be harvested, comprising:a right side frame,a left side frame,a center section having a right side and a left side supported for adjustable vertical movement relative to said right side frame and said left side frame respectively,power means mounted in fixed position on one of said right side frame and said left side frame,traction means for contacting the underlying surface and being fixedly mounted to each of said right and left side frames and coupled to said power means, said traction means providing for movement of the tractor over the underlying surface,an operator control station for providing control of tractor movement, said operator control station being mounted in fixed position on one of said right and left side frames,first means coupled to said power means for moving said center section right side vertically on said right side frame,second means coupled to said power means for moving said center section left side vertically on said left side frame, andlevel sensing means mounted on said center section in communication with said first and second means for moving, whereby a change in said right side frame elevation results in a substantially equal and opposite change in said center section right side elevation and a change in said left side frame elevation results in a substantially equal and opposite change in said center section left side elevation.
