It will pull as much amperage as it needs. Your battery has somewhere around 400(?) amps available to the system. To get that much 12v power is not going to come from a regular wall outlet. A good battery charger with the jump feature puts out 200 amps. My suggestion if you want to plug it in to start better is to plug it into a trickle charger when not in use.
Now my outside the box answer is too bad your a quiet line guy and don't have any with a starter generator. You could pop off the s/g and mount a 110v motor to the bracket. If it was a plow tractor you could make a bracket to back feed through the pto to start so the a/g would still power lights.
