$60,000 Food Plot Mower?

I used to sell product to a number of turf guys, and the prices they told me these mowers garnered were insane.  But when you put in diesel engines, hydraulics, and needed a precision cut, they get it.  I have no idea what this unit costs, but I'm betting it's more than the value of my land.  I'd be blown away if it was under $20,000 for the tractor and mower.  I sent an inquiry to the dealer in Georgia to find out.
