First post, long time lurker-- just registered. I have owned Exmark's for about 15 years, and I just recently sold a couple of older mowers which has put me into the market for "looking" at a newer z. I'm still using my 60 inch exmark lazer z from 2000 with 1550 hours. It's a 23 hp liquid cooled kawi with the ultra vac system. The question I have, is how much better is this newer g3 laser z mower then the older one's? Mine runs great, does everything I need it to and more..but I really like the newer mowers features. I was looking at a 26 HP Liquid 60 inch Kawi and the price with the new bagger system is staggering. Is it worth my time to upgrade or just keep my reliable older one? I want liquid cooled again, not air..it runs so much smoother. And no Diesel, I had a 66 inch diesel triton that I put 100 hours on and sold..the worst mower I ever owned with that deck. I'm mostly looking for how much everyone like's their newer exmark laser z's..the g3s.
