The 720 maintains about 60 miles of forestry roads, probably grade and maintain 200 lane miles a year with it, which is why I can get by with it, I'm only puting 50-60 hrs on it at a stretch, maybe 200-250 hrs a year. I havnt tried sourcing parts for the transmissions yet but I'm planning to figure that part of it out when I have some time just so I know. The motors are common as heck in the US and depending on which one it is ( the 720a should be an 8.3 cummins) I've found used motors in the 3-4k range, I'd assume a 10k hr life span out of a properly maintained motor, possibly longer. Not sure about the tandems, knock on wood I've tried keeping fluid clean in them and havnt had any issues. The brakes seem to be an issue in sourcing parts for at the momment. I had gotten a pair of wheel cylinders
for mine last year and at $250 apiece was told there were three left in existance. I bought 2 of them and vowed to source them elsewhere but havnt been able to yet. probably should of bought the 3rd one and put it on the shelf.
The 720a was a really common machine, I've tried buying them 3 different times at auction but I refuse to pay a JD price for them, because honestly they will do the job just fine, but at the end of the day the resale value is going to be lower than a JD.
What is a 720a going for over there?
