We have a i1046 ZT that is maybe 5 years old and has been nothing but trouble since we got it. A few weeks ago it began to lose power going up hills. The motor didn't lose power, just the drive. A loose drive belt was the suspected culprit. We tried belt dressing but that didn't help. We brought it into our local cub cadet dealer and they took a look at it. They were able to tighten the belt and for now they say it works okay. But they recommended a replacement. This will necessitate removing the body (!) and 9 hours of labor for a cost of around $800 or so if all goes well. Does this seem right? I looked up a video for hydrostatic drive belt replacement, and while a bit complicated for the technologically challenged, did not appear to necessitate such extreme measures. Are we being led on here?
