for that amount of land you have a subcompact would suite you fine. if it was me I would prbably go mahindra, massey ferguessen or branson. with r1 ag tires and not the r6. with subcompacts you need every bit of wieght and traction you can get. Ive used mine to cut hills my 4x4 truck wouldn't go up. also a pto belly mower uses alot of power and will be pushing the limits of 23 hp mine likes the bushhog alot better. I would also look at what rpm your hp is coming from.
