I have WeedEater 26 in. 190cc Briggs and Stratton Rear- Engine Riding Mower bought from home depot. I got a flat tire, after I changed the tire, the mower won't go forward. Anyone got any idea the reason?

Thanks.

Check and see if you lost the key way in the axle .there should be a slot in the axle and one in the wheel , the key goes in there,

Thanks. I checked the related posting on the site and found a similar posting. That may be the exact reason. I took a tire from another riding mower I have and the tire did not have the key. I just bought the inner tire and put it in tonight. Will put the original tire back on the mower to try.
