ABSTRACT:
A soil cultivating machine has a row of cultivating members journalled in an elongated frame portion. The rear of the machine is supported by elongated rollers positioned side-by-side and pivotable arms interconnect the lateral roller ends to rear plates on the frame portion. The arms and working level of the rollers are settable and beam supports extend from the plates upwardly and forwardly to an apex connection to a trestle top. The trestle is a coupling with points connectable to the three point lift of a tractor.
