With the tractor not running/ignition switch and all known accesories turned off disconnect either the positive or ground cable from the battery and install an ammeter(mutli-meter) in series with the cable you unhooked and the post on the battery............if you have a draw you will have a reading ex. .7 - 1.3 amps...........
Leaving the ammeter connected, start disconnecting electrical accesories one at a time until you find the source of the drain, the ammeter should read 0 or close to it(the clock in the radio will draw some/minimal amperage - in the mA range)............
Another less sophisticated tool that can be used in place of the multi-meter is the spark/arc-meter........to use simply disconnect either the ground or positive cable from the battery and observe........if a spark/arc is present, there is a draw, the stronger the spark/arc, the higher the draw..............
