Why does my tractor keep draining the battery?

get a DC volt meter and check voltage at battery post before starting tractor
start tractor and again check voltage at battery posts . you should be getting between 13 & 15 volts,if not charging circuit is not working.
Its either a voltage regulator problem or a stator (located under flywheel) problem.
Stator produces AC voltage to regulator so you need to set your volt meter to AC ,most stators have a plug exposed insert red and black lead of meter into each side of plug, you should read around 23 to 26 volts AC if no reading stator is opened (bad). The PTO clutch requires a full 12 volts to stay engaged. you could have a bad battery bad cell .have seen new batteries be bad.

I have a Husqvarna 21 HP Lawn Tractor and I went out to start it and the battery was totally dead, so I jump started it. It started but died out a couple times. So I got it going again and drove it up the...

The electric clutch needs full power in the battery to stay engaged. I would recommend you check your charging system before replacing the battery. Put a digital volt meter across the + and - terminals of the battery and while running at about 1/2 throttle you should be over 13 volts DC. Probably around 13.5 or so. If not you have a charging problem. Lawn mower batteries I have seen seem to last only 2-3 years. I would also recommend a trickle charger for extended periods of non use. Don't forget the Stabil also.

Hope this helps.

Mower starts but when you engage mower it stops

Check for a weak battery. On some lawn tractors the mowing deck is started by an electric switch, and when the deck is engaged it pulls all the remaining power from the battery thus robbing the engine of the current it needs.

Craftsman lawn tractor model new battery drains quickly...

it could be the stator in the engine check the voltage with the volt meter when its running if its low check connections on battery & voltage if its below 12.5 volts then its the stator but the only thing is the engine should run with-out the battery so there is something else going on there is a fuse in the electrical system if theres a short that fuse will blow & engine will stall
