Use solar panel since tractor's generator not working?

you can use a tricklr charge on a deep cycle 12 volt battery this will hold up many hours longer and be more durable than than the battery in there now. If you keep drawing down a battery not made to dranw down eact time it will become less and less charge. A deep cycle battery will hold up a heck of a lot farter down the road.the solar panel will never hold up to the severe vibration of the tractor, and it is a delicate peice of equipment to begin with. put it on a building or some place safe that will keep it from being knocked over or anything else.
