I've been seeing an oliver 1850 gas with 6000 hrs and in above average condition, I can't decide between that and an IH 856 diesel with less than 4000hrs and one owner. The IH is $ 3,000 more. I have less than 90 acres and want a larger tractor for mostly tillage and hay. I already have a 50 hp tractor. Looking for the larger tractor due to time constraints and because I want a larger one. With how much more diesel is in Pa., I'm not sure I will be having much saving with diesel but I won't be working the tractors daily with most chores using the 50 hp tractor. I've also seen an oliver 1955 near by for $1,500 more than the 1850, but was thinking it might be too large. looking for opinions. Thanks
