I have a 42" Murray Riding Mower (Model 42598x92A) that runs great. I'm not super mechanically inclined but I'm handy enough. I feel confident enough until I get into the engine/transmission issues.
The engine doesn't bog down or stop ever but I sometimes lose speed and sometimes the mower refuses to move at all. The engine runs totally fine and the blades will rotate and blow grass just fine. It is worse going uphill.
My assumption was it was the motion drive belt. I was given this mower by a family friend that upgraded to a zero turn. He's a mechanical engineer, maintains his equipment well, changed the drive belt before gifting it to me, and sent the original manual and spare parts he had for it. I talked with him and he was convinced it wasn't the drive belt because he just replaced it but after countless tinkering I went ahead and replaced it anyway. No improvement so far. I'm thinking it may be the tensioner pulley but I really don't know how to check for that. When I engage the brake, the pulley does move.
When it stops moving, I can hold the brake, engage the gas pedal, and when I release the brake it'll lurch forward. It often continues forward if I'm on flat land or downhill, but it usually is at a snail's pace. If I let it sit for a while (usually a couple hours), It'll work fine for a while and then go back to this problem. I've been mowing my yard in multiple shifts this summer because I can't figure this problem out. I would love some help. I may need you to explain it to me like I'm a 5 year old depending on the solution.
