Engines were placed in the safe protected from fire place. Pick-up of a header was carried out by means of the electric drive.
In 1952 the MN-726 model was replaced with new Massey Harris 780 which had much more widely a threshing drum. The 6-cylinders diesel engines with 56 hp power were set on these models. Harvesters were equipped with a hydraulic adjustable header.
