I'd be interested to know how the Radius deck stacks up to the Tri-Vantage deck you had on your Lazer. Those tend to clump in wet or lush conditions. My Lazer Z HP with the Tri-Vantage is still in the garage awaiting my attention. It's been laid up for a year since a friend broke a pulley. I've got the parts now but have had better things to do. Engine is tired at 1900 hard hours too. The 2002 walk behind Turf Tracer HP is still going strong at 2600 hours.
I really love my Exmarks. They leave such a beautiful cut!
