Marking machine with external drive carriage

The simplest way to turn a hand-guided machine into a road marking machine with drive is to use a drive carriage. This is coupled to the marking machine by means of a trailer coupling. The mode of operation of most drive wagons is identical. By means of two pedals on the feet, the machine can be driven forwards or backwards. Try out these cars also on inclines. Does it start quietly? Is it strong enough to meet your requirements? How can it be parked? How safe is the device? Is there a work light? Brakes, etc.
