Hi there,
My name is Dane and I'm going to help you as best I can. You didn't give me your model number so I don't know what you have for sure, but I can direct you somewhat. First I want you to reconsider the belt. It can look fine but if it's stretched or worn slick, that mower ain't gonna go anywhere. Normally, these hydrostatic transmissions have belt driven hydraulic pumps attached to the transmission which is normally a closed unit that Craftsman really don't want you messing with. Some of them have dipsticks and oil filters, some don't. If yours has a dipstick and filter, maybe you should consider changing the oil. Any hydraulic fluid will loose viscosity after years of service and maybe that's what has happened here.
If the mower just didn't go one day when you got on it, I don't think the transmission itself is your problem. Normally they start slipping over a few mowing days. I would check all of your transmission controls. Your foot pedal and shifter if it has one. Check the linkages all the way from the pedal or shifter to whatever it moves or rotates on the transmission, and make sure it has full travel there. Many times it will be a simple pin has came loose somewhere. I wish you luck and hope you find a simple problem. Don't forget to double check that belt!!!!! Thank you!! Dane

Tractor will not move with engine running Craftsman 917.287070

Make sure your drive belt, the topmost one, is in place and snug on the pulleys. Do not do this while the engine is running! If the engine is running fine and the belt is transferring power, then the problem lies with your transmission. You can find these used at mower bone yards and on ebay.
As most of these lawn tractors are made by just a few companies, you will find the same transmission is in many different mowers.

I have Craftsman 42" lawn tractor with the automatic transmission. It runs fine but it is not pulling a grade now. The belt seems tight, what could be the problem?

As you attempt the incline grab the clutch pedal with your heel and pull it towards you if it starts pulling correctly you have a belt problem . If it makes no difference you are having hydro pump problems

The tractor will not go forward or backward it starts right up but will not engage

1) The drive belt between the engine and transmission has broken or jumped off a pulley.
2) Your hydrostatic transmission is dead.

I have the same ,Sears Kohler tractor won't pull uphill

Have you checked the fluid level in the hydro trans, there is a drive belt from the engine to the hydro trans check and make sure that this is not worn or loose. Make sure that when you check the tension of this belt that you do not have the engine running or the parking brake set, since tension will be released from the belt when parking brake is applied. good Luck

My YS4500 (3 yrs old) has recently been loosing power in the hydro transmission. The engine runs great, but the drive stinks. I have to ease it into drive and as it gets going it will pick up speed, but if...

Yes, what I believe you have, is a loose drive belt. this can be due to several things,1st, the drive tensioner spring may be broken, 2nd,the drive belt tensioner pivot arm may need lube, or the belt is worn out.
You did not mention the hydro making noise(whining) if that were the case i would have you check to see if the brake were sticking.

Craftsman Transmission problem

Some of these tractors have a friction wheel that is driven off of a flat wheel on the bottom of the engine drive shaft. The rubber ring on this friction wheel could be worn out, or it could be out of adjustment.
