While using my Craftmas 17,5 hp lawn tractor with a snowblower attachment, the hydrostatic drive seems to loose power, especially when it working hard and after its been in use for a while. I don't think...
Hello,
My name is Dane and I'm going to help you with your problem. First, I believe those craftsman units are sealed and there's no way to actually check the hydrostatic oil level. So the first thing to do is make sure that you don'thave any leaks around the transmission assembly. If it looks clean and oil free, I would venture to say that it is more of a 90% chance that your drive belt is the problem, however it isn't from icing up, but rather from the heat of the extra work from the weight of the snowblower, causing it to slip. The belt isn't all that expensive and before I would get excited and start worrying about transmission failure, I would just replace the belt first, and rule it out. Make sure all your pulleys and tensioners don't have any loose hardware, and look alligned.
I think you'll fix the problem though just by the belt replacement. I hope I've helped. Thank you! Dane
