I bought an X748SE new 6 years ago. It now has 834 hours on it. I'm wondering how long I can expect it to last. I mow about 5 acres, Blow snow with it, blade, and a 647 tiller. It always performs great. I must admit, most of the time I feel like I'm torturing the poor thing. I change the oil and Hydro fluid , and other service every 200 hours or every year. I have seen posts on this forum that the X series would probably only last 600 hours. I find that rather amusing since that would only be 3 oil changes and mine works like new.
Haven't had any trouble with it except a couple of bent front fenders. The deck could use new wheels, but otherwise that looks good as well. Should I trade soon?
