Hello all. I have recently become the owner of an Oliver farm tractor that will be used maintain a hunting property/ deer food plot.  It is a gas model and I was told that it was rated at 74 HP.  It looks similar to the 1800 series. 

The Model # is 28-2105 and the Serial # is 124- 622-844.  I would appreciate any help in identifying the model and year of this tractor.

Thanks.
