key position

I know this sounds dumb but right now I am having problems with my key position and running the battery down. Am I not correct in saying the key has to be vertical when off. If I'm wrong you can tell me. Thanks,
 
What tractor and is the ignition system still stock? Generally for a key started engine being able to remove the key is a sign it's in the "can't kill the battery" position. Assuming it is a good switch.

There are multiple ways a battery can be discharged when the tractor is off.

Key left on will discharge the battery.
If tractor is a gasser, and has a distributor ignition system, it is providing voltage to the coil when the key is on. A voltage measurement at the coil will tell you if the key is on or off. If voltage is left on to the coil and the points happen to be closed, you will eventually burn the points and probably melt the coil.

A stuck cutout in a voltage regulator will drain the battery when all is off, as will a bad regulator in an alternator. To see if you have a drain when off, disconnect the ground cable from the battery, and insert a small test light between the disconnected cable and the battery post the cable came off of. If there is a current draw the lamp will light.

Incorrectly wired instruments can cause a drain. Such as any powered gauge that continues receiving power when the key is off.

Imho, the most common drain is a bad voltage regulator. Some folks just disconnect the battery ground when the tractor is off to avoid draining a battery, until the problem can be isolated and fixed.
