Most lawn mowers do not use a push rod to open and close the valves as the end of the valve stem sits directly on a cam. The cam of the camshaft opens and closes the intake and exhaust valves. This is called an Overhead Valve or OHV.
IF a large, old engine does use push rods, apply the same methods as used in an auto or motorcycle engine,: Namely, remove the valve cover and then the valve train. Each valve has a push rod in an opening underneath each valve rockerarm.

Mower will not move in either dircetion?
Don't know what kind of lawn mower you are talking about. Sounds like your transmission is not engaged. Try this: All the way at the rear you will see a metal panel with a skeleton key-type looking hole (large and round at the top and then it narrows and gets straight at the bottom). There is a rod that comes through the hole, it is spring loaded. Pull the rod through the large round part of the key hole and on the rod you will see along the rod a built in washer-type ring. Make sure the washer-type ring comes through the hole and push it down to the small end of the key hole so it will stop it from going back through the hole. This engages the transmission. It is called the "free wheeling rod." To disengage the transmission, to make it easy to push, you pull out the spring loaded free wheeling rod and lift it up so it will go back through the large round part of the key hole. I would try this first. Mike
Back tires on riding lawn mower move in opposite directions?
If the tires are moving in opposite directions when you try to move the mower there is one of two things happening. Either the mower is stuck in gear or the brake is hanging. The more common is that the brake is hanging. If you can, have someone on the mower with it NOT running. Have them press down the brake pedal while you are watching under the mower and on the rear axle. There is a rod that goes to the brake assembly. The rod is pushing the brake linkage. Usually the bracket is stuck. You can pull it back forward and the brake will release. If it happens frequently you will need to lubricate the linkage without getting any lubrication on the brake discs themselves.
