The older Bolens tractors that were made before MTD got ahold of the company were darn good tractors. i do not profess to be any sort of expert on the breed but apparently they are divided into Small Frame and Large Frame models, with the Large Frame units being the most desirable when it comes to working the land.
While I am firmly in the Case, Ingersoll camp.... I cannot ignore some of the other brands that also produced some very capable machinery. There are quite a number of Bolens tractors out there that are still giving stellar service every day. As mentioned, the one on offer is a large frame model and presumably it is priced OK.
When searching for a suitable tractor, you should keep all of your options open. Spending some time on one of the Bolen's forums such as My Tractor Forum would yield more information that could help you decide which way to go. If ground clearance is a big issue for you, then that is one factor you should compare between the Case Big Wheel models and any other contender. Very few garden tractors come with 16 inch rear rubber and that gives them an edge when ground clearance is a priority.
Realistically, any garden tractor that has 12 inch rear rubber is going to have less ground clearance than that of a Case/Ingersoll Big Wheel model. Pretty much any tractor can be fitted with AG tires and then weighted down to find good traction but there is no way to create extra ground clearance.
