I see it only comes with a Kawasaki gas guzzling motor. Needs a diesel. Main reason why I traded mine in for the Kubota diesel front mount was the gas guzzling Kawasaki. 5 gallons of gas per mow wasn't a cheap date and neither was the overall maintenance. I'd buy the Ex-Mark if I had the need in a minute. I don't and I'm seeing prices in the low 60's here, not 73.
That is for the man or woman that just hit the lotto or is inherently rich with money to burn.
For a lot less you can get a fully equipped John Deere or Kubota front mount mower with bagger and all weather air conditioned cab for under 35 with a diesel engine, plus the JD and the Kubota accept a lot of implements designed for them. You can get snow plows or power brooms, snow blowers or buckets or other stuff as well and a climate controlled cab with all amenities as well and it's 4wd to boot.
Like I said, if I had a use, I'd buy one but not for the asking price. For me, it would be a write off anyway but I'd still never pay list for one. All that stuff has big wiggle room.
