Abstract
A control system is provided for starting electrically powered implements on a vehicle such as a grass mowing machine with electrically powered cutting reels. The electric motors are started at intervals, rather than simultaneously. The intervals between starting each electric motor may be based on pre-defined criteria such as a fixed time constant, voltage, current or speed input from a motor controller for each implement.
