Hi, I currently have a JD LX178 that I bought new back in 1998 which still runs good, although slow starting. I keep the oil changed and take care of it the best I can. Not a lot wrong with it, but yesterday the tie rod came loose, the ball separated from the socket but I got it back together and while sharpening the blades I did see a dime size hole in the top of the deck. I took it in a year or two ago for a spring tune up, oil change, etc. where they did find some other things that was needed to be done which totaled around $600.00. I have been thinking about a new one and with the sale going on right now I am looking at the S240 or the X330. I keep reading and hearing how people are not happy with the Briggs and Stratton engine or the rear end that JD puts in these models. I only cut 1/2 acre with very very slight hills. I used the 178 for pushing snow also but I am tired of putting the chains and the blade on every year so I am not going to do that with the new one. I have no problem spending a little more to get a better product but do not want to buy more than I need. So I am just wondering what your opinions are on this. Fix the 178, and runner till she quits, or maybe you could help me pick a model that would work best for me. Thanks in advance for any advice.
