Is very hard to get going up hill especially from a standing start.
How old is your machine? I have a John Deere X300R which after just over 200 hrs got slow going upslope and then when hot would actually run back while on full revs and pedal right down hard. Contacted JD who said to get it "Lapped". Cost was $1,400 and likely to result in same again after another 150 to 200 hrs. This was a K46 drive unit. In the end I bought a K66 transmission and butchered the chassis to fit it. It is OK but I would not do it again as it cost about $3,000 all up and is not ideal. I am a retired manufacturing engineer so had the skills and gear. I suggest that your machine may be like mine was. I filled my new drive unit with synthetic oil, 15/40 grade and although expensive, I believe it is worth the expense. There is no quick or cheap way of overcoming the result of a defective drive unit that I know of.

This symptom is cause most often by the following.
Worn and slipping drive belt which is separate from the blade/deck drive belt.(replace the belt).
by-pass lever (rod) not fully engaged (push it all the way in)
travel pedal or linkage is faulty or out of adjustment ( take to dealer)
Transaxle is faulty (take to dealer)

i had exmark hydros i was told to never wash them, the water does more damage than good. have you checked or changed your hydostatic oil and filter latley? if you have, when doing that you have to be very careful not to get any foriegn objects in the oil resevoir, dirt, grass clipings, anything will ruin the hydro pump.

You didn't indicate what model so I don't know if it is hydrostatic drive or not. If it is not hydrostatic drive, it is most likely a worn belt or clutch adjustment. If you don't have your manual you can download one here:http://www.mtdlawnmowerparts.com/manuals.php
If it is hydrostatic drive it stil could be the drive belt or low water in hydrostatic transmission, or even water in the oil in the hydrostatic transmission. Always list model number when asking questions.

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

for not charging pull the cover off the top of the engine look for damaged wires mice love to eat them going slow i would check the belt for oil or see if its tight
