a pretty rare and unique piece of tractor history there. at least in my part of the world. we have the green version of that, an m, in our family. it was my dads and my son has claimed it. no attachments for it though. the jd m had several versions. the m (set up similar to yours) the mc (a crawler) and the mt (a single wheel tricycle kind of like a hi-crop). the mt could also be fitted with a wide front or twin narrow front tires but still had more clearance like a hi-crop.
