    I absolutely love it! For what I do as a homeowner and few side jobs I wouldn't be without now. As for converting yours I believe it would be much cheaper and easier to trade for one with a blade or purchase a dozer! I was able to find the balde and ship for around 4k plus my labor. Our machines...

    blade added

    Yes! My machine originally came with a blade! Best I can figure is at some point before I owned it the undercarriage was replaced , all of the blade componets were still in tack minus the pilot valve in the cab! The blade circuit on this machine actually has is own separate pump!
