Gary,
To help in troubleshooting the electrics of the starter circuit I'll throw in my nickels worth.
You mentioned having a solenoid and heard it click so lets start there. A solenoid is a 'relay' and it's purpose is to allow using a small switch and low current to controll a large switch capable of carring the large current draw of the starter. If you hear it click thats a good bet the control circuit is intact. The next step is to determine the fault in the battery-starter portion of the circuit. The process of bypassing the solenoid has been discussed but the post is still asking 'how?' Start at the battey and you should find one cable connected to the frame of the tractor. (I don't want to get in the male bovine excretement of positive or negative battey so just keep it binary, battery and ground.) The other cable should go to one side of the solenoid (big connector) the other side of the solenoid should have a cable connected to the starter. If you find all this then we're ready to bypass. !!!BEFORE YOU DO ANYTHING SET AND LOCK THE BRAKES AND PLACE THE SHIFT LEVEL IN NEUTRAL!!!
If you have a jumper cable connect one end to the battery at the post going to the solenoid then go the connector on the starter - connect the jumper to the connector. WATCH YOURSELF, SPARKS WILL FLY(assuming a good battery) AND THE JUMPER WILL HEAT UP QUICKLY. If at this point the starter turns clean or replace the solenoid. If the starter doesn't turn you have pretty well isolated to the starter. Go ahead and get the starter out. My guess is, like some other have said, the starter drive is hung to the ring gear.

PS. If you don't have a jumper you can get cheap and dirty and use an old tool to short the solenoid contacts BUT the most professional way is aquire a volt-ohm meter and test your way thru the circuit.
Hope this helps and good luck.
