    I purchased to cut and mulch corn stalks to prepare land for no till cover crops.pleased so far

  2. Jim Geyer

    Very good product had a problem they corrected it immediately will definitely buy from victory again Thank you for all the support


    A solid machine with good sturdy construction, heavy gauge metal. It is my first fail mover and seems to cut and mulch just as I would expect. The most important compliment is the staff responded quickly to an issue I had with the machine. A very professional and ethical organization.
