I have a Murray 20" plain old push mower. 2 of the wheels have gotten quite loose and make it very difficult to push as they go on a slant now. I thought I could just tighten the nut but nothing happen. I can't see under the mower to well but it appears to be a normal nut (may be wrong) but when I clamp it and tighten the bolt it doesn't actually tighten. I did notice that the bolt doesn't slide like one would expect if the nut was loose.
Any Help??

The bolts that hold the wheels on a push mower are shoulder bolts. They have a sort of smooth shaft area from just under the head to the threaded portion, which acts as an axle for the wheel to turn on. You can't tighten these wheels, as the shoulder of the bolt will already be in contact with the frame of the mower deck. What's most likely happened is that the inside of the wheel itself, which is probably plastic, has simply wallered the hole out to a size that allows it to flip flop from side to side or just run sideways. You need to get to either a good hardware or a mower repair facility and buy some new wheels to install. Then you'll be back to mowing straight.

Mounting Tubeless tire on Rim of riding lawn mower?

I have a flat tire of one of the Larger rear tubeless tires on my Yard Machines MTD riding mower. The problem is when I apply air from hi-pressure hose, there is no way for the tire to seal around the rim so it inflates. There must be a trick to get the tire to basically puff up so it expands over the rim. One auto tire guy suggested rubbing soap and water around the tire seal on both sides and as I apply air push in on the tread......well no that didn't work.
The mower is on a jack lift so the tire spins freely.
I'm using a mechanic shop quality air pressure electric pump.
That's the deal. Thanks George.

Run a good stout rope around the circumferance of the tire, in the center. Use a long screwdriver or bar and twist it tight. This will make the tire flare out and seat the beads on the rim. Put air in it, you will be able to feel the tire taking air. Untwist the rope as it fills. I have also used ratcheting tiedown straps. When it starts taking air loosen the strap. At a tire shop they have a device that does the same thing but it inflates with air pressure. Just don't get your fingers in the wrong place. I usually leave the valve core out at first so the air will come back out but it will leave the tire seated on the wheel. It also might be easier to work on if you removed the wheel.
