Never have used an Exmark until Tuesday. Mowed some with a friends HP. Also stopped by a dealer Thursday and drove one around the lot. On both occassions noticed that the unit would jerk somewhat. It wasn't as smooth as the Scag or Hustler I drove. Could someone please enlighten me as to why that might be. Doesn't mean I wouldn't buy an Exmark. They probably have the most proactive dealer in this area in Campbell's. All they live to serve is commercial mowing and they have a very large market in that area.
