2005 Murray riding mower

Our mower can be pushed forward and reverse, but when started and put in gear it wont move. The belt is on.

 

It would help if you gave more information about your mower like the model & serial number. It would also help to know what transmission you have; manual or hydrostatic.

 

Sorry about that. Murray Model 425015x92B, hydrostatic. Sorry no S/N. Hope this helps

 

Did this happen suddenly or over time or? Need info to figure this out. Did you take a rear wheel off and then this happened? Am I safe assuming you've already checked the hydro relief valve that you move to roll it? It's all about details.

 

The mower had set for about a year and when we tried to move it it wouldn't move, so we pulled it out with a pickup. Replaced a tire( took wheel off) then did all the other minor repairs to get it started, and it wouldn't move. Started great. No did not check hydro relief valve. Have no idea where or what that is. We are beginners on repairing.

 

The hydro relief valve on most murrays is under the seat. It's a user operated lever that you move to the side if you want to roll the unit. Just flip the seat up and look to see if it's in the roll or drive position.

If the lever is in the right position, then I would suspect the axle key fell out when you had the rear wheel off. Take the plastic caps off that cover the clip that holds the wheel on. Start the mower and try to drive it. Do you see the axle in the middle turning on one side or the other? If so, that's the problem, the key that fits between the axle and wheel fell out when the wheel was off.

 

Raised seat no lever. Took wheel off and no axle key. Going to replace then let you know if that works.
Thanks

 

Well duh on us. it was the axle key all the time. Thank you so much. Now one more question. Why does the mower backfire after turned off.
Found S/N 7534006143R532

 

But was the axle turning when you tried to drive it with the cap removed? If it was, then you found it...if it wasn't you still have another issue I would imagine.

Ok...disregard this......glad you found the problem.

 

The mower backfires when you turn it off because the anti-backfire solenoid on the bottom of the carburetor isn't working. You can help stop this by letting the engine slow down to a low idle and cool off before shutting it off, and/or fixing the solenoid.
