140 won't turn over

Alright, guys, I have a problem. Just yesterday I was out working the 140 a little bit in the garden. It ran fine and cranked right up. Today, when I went to start her up, she wouldn't even turn over. Not a sound! I took the battery cover off and there was a pile of corrosion on the negative terminal (it is 6 volt positive ground). I replaced the terminal, but it did no good.
I don't know how old the battery is, as there is no date printed on it.
My question is this: What is the most likely source of this problem? It will burn the lights, but the engine won't even move.
Thanks in advance! SF

PS: I have the tractor on a battery tender to maintain the battery, but the charger never shows a light color other than solid red. Thus, the battery is never over 85% charged:
Flashing red - not charging
Solid red - charging
Flashing green - charging over 85%
Solid green - fully charged and maintaining
 
The battery could be bad, otherwise 99% of the problem is bad connections. You can usually start a C113/123 with a crank. With a weak battery, the starter takes all the electricity, leaving none for ignition. Clean up your connections, new cables if necessary, along with the battery.
 
Just for the sake of argument, put the tractor in high gear and rock the tractor back and forth. The bendix might be still engaged. My M used to do the same thing till i lubed the bendix. the starter gear would stay engaged on the flywheel and you would have nothing when you hit the button the next time. I could rock the tractor and hear a clunk from the starter after that it would fire right up. just something to try!
 
When that happens first thing is always check to see that the starter isnt .ocked up on the flywheel . Put the crank in and see if you can turn the engine over if not remove the two mounting bolts after removing the batt cable then you can see if the starter drive needs attention. Check all batt connections even the starter sw.
 
If your engine moves when rocking it in gear I would check the specific gravity in each battery cell to make sure you don't have a dead cell. The readings should be around 1.250 and all the cell reading should be close to one another. If one cell reads 1.100 you have a dead cell. A good hydrometer is handy and you can check your antifreeze too. Hal

Yep! That is my analysis also.
 
Thank you all for your help! I have fixed the problem. I took the battery to Advance Auto, and they tested it. The man said that the battery was so weak it wouldn't even print out the ticket! The fellow also said that the battery looked to be about 6 years old. I guess I got the good out of that one! So, I popped the new battery in, and the tractor fired right up. It just surprised me that a battery could go from giving fine power to dead in under 24 hours of normal-temperature weather.
Thanks again for your help, SF
