I have had my x738 for less than a year, and "the blizzard of 2016" was my first snow with it. In switching from the front blade to the snow blower I wasted a lot of time trying to get the angle locking pin installed. Is there a trick to aligning the holes so the pin will drop in? Other than that, I love the machine. I upgraded from a 21 year old Honda 4518. A great machine, but the lack of hydraulics and the difficulty of switching implements made the upgrade necessary for someone 70+ yrs old.
