Our neighborhood is getting lousy with new mowers and yesterday I had the chance to use a one week old JD with four wheel steer and have reached a surprising conclusion, its FASTER than the Exmark, or more correctly; its faster than the Exmark if you don't want to leave zero turn labels all over your yard.
Approach the purchase of a zt with caution, making a 'zero' turn on turf will damage the grass. If you have to make three point turns to NOT damage the grass why not just get a good quality tractor?
I, like you, HAD to have a zt-both the brand and the use experience have been dreadful.
Cub Cadet has my attention also, while the JD is nice and works very well the cost does not reflect component quality. For the money you should NOT be getting a sealed, lower end drive, if Cub can offer a 'real' transmission why can't Deere?
Really would like to try a new Cub GT2000 series-it looks very nice, but then again so did the Exmark.
