Bobcat is made by Textron, makers of Ransomes, Jacobsoen, Steiner, Ryan, Bunton etc...Plenty of folks on this site use them and like them. This particular unit sounds a bit underpowered with a 60" deck 18hp combo. Most commercial ZTR's have at least a 23 hp or bigger for that size deck. I'm not to keen on Briggs motors for commercial mowers. I prefer Honda or Kohler or Kawasaki. Tell him good luck.
