I purchased a Märklin snow plow 49963, the red-brown one with sound and snow plow function.
However, it is well known, that the motor runs very fast and very loud. Furthermore, the motor starts immediatly together with the sound with full speed. But I found an description, how to modify the decoder and the circuit to control the snow plow speed with the drive function of the digital controller.
