Hi. I was recently given the use of a Grazer 1897v ztr mower (52") to use while my Ingersoll 4120 (60", Onan 20hp) is in the shop for a leaking hydraulic motor. This Grazer does everything better than my Ingersoll, cut quality, speed, fuel economy, ride quality, lower noise, etc. How is the durability of these Grazer machines? I have a 5 acre property to mow and use my mower 60 hours per year. I have quite a bit of unlevel, fairly rough terrain, and the Grazer handled it A-ok but would it stand up for me long term? My Ingersoll was $7200 six years ago ($9200 retail now) and now has 350 hours on it. The Grazer has 83 hours on it, Vanguard engine (18hp). How much do these Grazers sell for? I can't find any pricing info on the web. I am contemplating some sort of trade but I want a mower that'll last with my less than perfect terrain. TIA.
