I am looking at getting an 1855 with a loader on it.  The history I was given is that at 300 hours it blew up proper. An old Oliver mechanic rebuilt with a different block along with all updates. it now has about 3700 hours.  I plan on using it to clean up around my farm and down the road using it for a small farm main tractor.  is this a good tractor to go with.  thanks
