Charge the battery completley. Test the battery voltage. It should be right around 12.5, if not your battery is week. Start the machine, rev it to up and check the voltage again, it should be 14 volts are better, if not you charging system is not replenishing your battery. My bet is your battery is not being recahrged and the added stress from the plow lift is draing down the battery.
