Im a novice at best but I recently bought an old tractor that has been caked in grime and is in terrible shape, but it runs and that is important. Its a diesel and from what I have learned it is most likely an 801, 860, 861 or 1801 but I cant figure out for sure which one for sure. The decals on the hood say 1801 industrial and select-o-speed. Whats left of the serial/model number on the transmission block I can read 860 on the model. The sheet metal paint scheme and egg crate grill look to be 801 type and even have the opening on the dash for the select o speed controller but the tractor has a 5 speed transmission. It currently has a front bucket on and a blade on back with the 3 point. Can anyone help me further identify what year/model it is with other info?? Thanks in advance
