Well, I've had my new Lazer XP 31 hp 60" for almost a month now, so I thought I'd give you all some feedback. I have owned a 25hp 60" lazer for two years and I can sum up the difference in one word, "WOW". The 31 hp is such a notticable difference (yeah,I know 25 verses 31 )in power and the transfer of the power to the blades ( no shaking or bogging when engaging the blades ) I'm getting the foot lift for the 25 for sure. Still not to sure about the suspension seat ( nice but I think the new standard seat is more comfortable for me, 6'3" and 300lbs ) I know that it only goes 1 mph faster but it seems alot more than that, It seems I picked up an extra acre an hour. The one thing that could be a problem if it was any wetter than it is is the weight, 1500 lbs. Over all it was money well spent (and it was a lot spent this year with this machine and two new hydro ecs and two new trimmers)I give Exmark two thumbs up for the lazer XP and the Turf Tracer HP ECS.I can't wait untill fall when I'll get an Ultrvac for the new lazer.
