I never did like our Exmarks with the Kohler engines. We have a 2000 Lazer Z that is on its 3rd engine. They all burn oil like crazy.
The one Exmark we have at the shop I am located in has s 34hp Kawasaki. I like that engine a lot. But, now Kawasaki has a recall on a lot of their engines for cam issues and Exmark is not offering the Kawasaki anymore until the problem is fixed. We have to get Kohler and we just ordered 3 new mowers.
