I have been around GRAVElys a lot. As long as you're not cutting a lot of trash grass (crab grass etc.) or wet grass it will do fine. At 675 hours the bugs should be out of it. Yes, it's worth $3500.00 but I would only offer $3000.00 for it and see if I could bargain it down. After purchase I would do 2 things. First make sure the engine is turning the maximum RPMs allowed by Kawasaki (3600 I believe) and second, I would add triangular gussets to the end of the blade baffles. If you want to see an example of the gussets just look under an Exmark deck. The gussets will minimize grass clumping when cutting tall and thick grass.
