Last year had valves adjusted, replaced battery and starter solenoid. Used Lawn tractor all summer last year. Battery has been on motorcycle trickle charger all winter.
This is first time to try to start it this year. Cleaned battery posts and cable. Battery testing shows full charge and 13 volts. Tried to test starter solenoid, by bypassing solenoid. Not so sure I did it correctly, because nothing happened at all. It's difficult to see down in there with battery connected to bypass solenoid correctly. Shouldn't it have turned over? When I turn key to start, No clicking, no noise, will not turn over, only a light on display comes on that normally lights when I start it.
First thing I would do is disconnect the battery cables and clean them with a wire brush really well, next would be to search for the main power fuse holder and check the fuse for being blown.

Battery might have the Volts but does it have the Amps to do anything

was the fuel left on and the cylinder filled with fuel thus hydrolocking
Try to turn the motor over by hand if you can , with positive battery post disconnected for safety it should turn some , battery hooked up correctly ? Positive should go to one side of solenoid ground - should go to frame or motor base .

This is narrowing down to a clutch/brake safety switch, PTO switch or a seat switch problem. Is the brake locked down when you are trying to crank it. I the PTO turned off?
I had similar issue, after checking safety switches I replaced starter, the new,(Amazon), starter worked about 3-4 times and quit, replaced with same one as I had 30 day warranty and this one has worked out. Try hot wiring your starter from battery, that should bypass all safety switches and go from there.
I've found a common wire brush won;t remove lead oxide very well . Maybe that's why a certain battery terminal brush was invented . I scrape them with my pocket knife until the lead shines bright .
I agree to try and turn engine by hand. If can't remove the spark plug. Turn over a few times to clean the jug. Leave plug out. If you have jumper cables, connect black to battery Neg and the other end to a clean spot on the engine's case. Connect the red to the starter's power connection bolt in the side of it. With everything tight and not shorting to anything else, touch the red jumper lead to the battery's Pos. It should spark a bit and spin the engine. Won't start due to plug out and Ign key in off position. If this work's then you have an electrical problem. Start at ign switch B terminal and see it 12v is there, if not check fuse. Check that all the safety switches are satisfied. Especially seat switch. Turn the key to start and see if 12v at the S terminal. If so, probably solenoid related. There should be 12v at the small terminal of the solenoid with the key in Start pos. Solenoid has to be grounded either thru a small black wire or the mounting itself. Check and clean all connections as you go along.
I'd be pretty sure your battery is a goner... Had it recently myself, charges up (unusually quickly), shows more than a healthy 12.7v coming off the charger, powers the low wattage lights / instruments ... But no cranking amps on a key turn. Take a healthy 12v battery (out of your car?) and attach with jumper cables.
