Hello Keith, I would recommend disconnecting the batteries (have them clearly marked so when they reconnect there is no confusion) also tag the machine that the batteries have been disconnected. (this will help make sure batteries stay charged, a month is a long time for batteries to sit so it may still require a jump start) Keep exhaust covers on. 4 weeks from now, reconnect the batteries properly, remove exhaust covers, check all fluids and do proper walk around and pre checks before starting machine. Thank You, Les
