These are the three I am trying to decide between. I like the gravely the best, but I would get better dealer support with the Scag or Exmark. This is my first big mower. I have $3000 to spend on it, It will be a fixed deck gear drive. Prices: Scag- $2500 Gravely- $2600 Exmark- $2700 I will be able to pull a sulky/velky with no problems on these mowers correct? I appreciate the help.
