Well I finally got to take my new 2011 SuperZ out for a test today. The new Hydraulic system is awesome. I thought my 09 SuperZ had smooth hydraulics, this new system is smoother and more responsive then the previous models. I did not cut much good grass but I did get to try it in clover. Some of the clover I cut was up to a foot or so tall and the machine cut and spread the clover great. I had no clumps or chunks roll out of the chute. It also seems like this machine has a smoother ride then previous. It could be because of the extra weight of the new mower? The new front caster wheels also work better no more "vibration" at high speed on the road. The mower is more comfortable for taller people with the new extended foot rest. Seems like the deck lift is lighter also. So far I am impressed with the new machine.
