Got a chance to look at the serial no. on the 800 Series I posted about last Friday. Good eye Jim.UT for saying it was a 1955 model. The serial no. is 6251 which, according to John Smith, is a 1954 model. It is also an 860 which means it has a live PTO. It appears that the front brackets that holds the front end to the engine will have to be exchanged from my non-running 850 to the "new" 860 in order to install the loader. Shouldn't be too big a job but I think I will need a helper other than the Misses. The rear brackets will have to be exchanged but they just unbolt from the finder brackets. Gonna have a little time off from work and I think with the help of my son, I'll be able to get the loader on in one day. What is the difference between a non-live PTO on the 850 and the live PTO on the 860?
