The Rhino 4150 Flexwing is heavy duty with massive gear boxes and 3 inch solid steel shafts to the blades. 15 feet wide and built in 2023 we have only used it to cut 13 acres of horse pasture once a month for the past two years during the growing season. It's a lot more machine than we need and it has had very light use. Barn kept and and in excellent condition. PTO is 1000 RPM. Tractor House did an evaluation on it and placed a fair value at $20,800. Brand new it was over $28,000.
