Ariens Yard Tractor 935 Series - initially drives, then stops moving as it gets warm

I was gifted this yard tractor recently. The owner said that it ran, and it does - it easily starts, the the mower blades spin, the engine sounds fine and it even moves forward and backward for a little while. But then, after 15 min. of mowing or less, going forward or backward becomes progressivley more difficult until the tractor doesn't move at all. After awhile sitting, the tractorwill move forward again. Any ideas on what this is? And what the fix is?

Is it a hydrostatic tranmission? If so, sounds like the fluid might be old or not the right viscosity. Recommend changing the trans fluid, and use recommended viscosity of fluid.

Is the battery actually fully charged? A dead cell will kill any power. Try another battery.

My Yard Machine tractor stopped moving in any direction. When the clutch is pressed in it feels sloppy and will not engage the gears when it is let up? What is the problem?

Check the main drive belt. It is either broken or out of place. It is the one driven by the upper pulley under the engine and drives a pulley on the transaxle.

I have a ariens yard tractor YT 150 H model number 936012 serial number 004697 . I have replaced the pto switch and the relay and every time I engage the blades the mower cuts off. Could you please tell...

I have the same model and had the same problem. Ended up being a bad bearing in one of the deck pulleys. You can find it by disconnecting the drive belt for the blades and turning the pulley by hand. One of them is going to be a lot tighter than the other. You should probably replace both while you have it torn apart...
