I have a 2004 Hustler FasTrak (serial #02117233) with an 18hp Honda engine. When it was new I mowed 10 acres and now I only mow 4 acres and cut paths through the rest. Its had a hard life mowing around fence posts, sometimes doubling as a bushhoog, mowing over bumpy, hilly grass and yes, getting stuck in wet areas. The hydraulics/transmission on the right side is shot. I can mow for about 45 minutes and then it needs to cool down. I really like this mower but is it worth fixing? Is it likely the other side will go soon, or the engine?
