It’s not the cost, just don’t know much about ZTs.
No Kubota dealer near me sells the small tractors, Would get one but no one to handle warranty if a problem arises on an out of state purchase. My dealer for the last 25 years closed and no others carry small lawn tractors. Have a Deere dealer close, looked at them. The one I was interested in had a non serviceable transaxle which I thought was a problem.
