Exmark with the Loncin engines are just fine. It’s just some people worship them and others won’t own one on a bet. Order I would put them in is Kubota, Exmark, Bad Boy. All decent units. Best thing I can tell you is give each one a good test drive, talk to the dealer about why his is better than the other two. Get down to two, then test drive each again. In the end go with your gut about which one you like best and which dealer you like best. If still undecided go with the dealer you feel will be the most helpful in the future.
