Übersicht von Bungartz Einachsschleppern -- Type H4, von 1953 bis 1956 gebaut von Bungartz in München
Bungartz H4, first series, 500 machines built during 1953 and 1954 (serial nrs. 1 - 500). Power source was either a TWN (=German Triumph) GeMo 200 or GeMo 201B, the latter having a governor driven by the amount of air sucked into the carburettor. Both 5 hp two stroke petrol engines.
Bungartz H4, second series, 25 machines built during 1954 (serial nrs. 501 - 525). Sachs Stamo 200 engine, 5 hp two stroke petrol without a governor. I had one of these in my collection, and know of one more in southern Netherlands, as well as one located at a collector in Austria. This model can be determined by the distinct, bulb-type air inlet to the carburettor.
Bungartz H4, third series, 775 machines built during 1954 and 1955 (serial nrs. 526 - 1300). The Sachs Stamo 200 engine was the first which was standard fitted with a governor, which all later models featured as well. The folder mentions that the fenders and lamps are not standard included, but the same applied for the trailer, vegetables and driver ...
Bungartz H4, fourth series, at least 655 machines built in 1956 (serial nrs. 1301 - ? (highest known nr. 1955)). First H4 fitted with the wider quick-action coupling for attachments, which was also used on all later models of this size (H5, FRN, FRK, FRNK, FK, F6).
