I'm on the fence....looking to add another Exmark to the fleet. Having a tuff time deciding on the Lazer A/S series or the HP. We have a 52" A/S right now and never had a problem with it. I'm considering the HP for its lower CG and no mule drive but am not to sure if I like the smaller frame and the smaller pumps. I also would be installing the ultra vac on it too, so I'm a bit concerned on the hp difference. A/S w/28hp Kawi -vs- HP w/23 Kohler Command. Price difference is $400. Anyone run a HP, which one, and how do ya like it?
