I purchased (2) of these mowers last August and have never owned a commercial zero before. www.toro.com says this mower comes standard with 24-12-12 tires but I see a lot of people with 24-9.5-12 on the 52" diesel?? any comments.. Second, this mower is VERY heavy, yes get a diesel for wet conditions for the torque, but you can't mow with it when it's wet because the back end is SOO heavy it is just as bad as have a skid steer on a yard. When you go to turn around it leaves a skid, I have about 400 hours total on each mower by myself and a lot of practice but I know it is the mower. Just looking for feedback on this mower and its weight compared to other toro gas zeros.
