Strange Lanz Bulldog D75?? - 25 HP

 


Can you help identify this very unusual Lanz Bulldog? It is a 25 horse-power with a serial number of 117368 probably built in 1938 and is located in South Australia. It combines some of the characteristics of both a D7500 and a D7506 (both of which were imported into Australia) but is neither of these. Note the following unusual features:

  • Front axle is of the type used for springs but this tractor does not have any. It is believed that no other Lanz tractors were imported into Australia with this type of front axle.

  • Oil-tank is part of the fuel tank as is normal for a D7506 rather than on the rear of the fuel-tank as with a D7500.

  • Air intake tube is of the type used with D7500 models fitted vertically at the rear of the fuel tank.

  • It has two foot brake pedals (i.e. turning brakes) which is unusual. D7506 models of the same period also had foot brakes but only one brake pedal. D7500 models did not have foot brakes.

  • The cabin guard-panels are most unusual. D7506 models had rounded panels, whereas D7500 models had panels with a single 30-degree bend. The cabin guard-panels on this tractor have 2 30-degree bends and at the rear are rounded down vertically in such a way that they finish much further forward than on either a D7500 or a D7506.

  • Probably because of the unusual cabin guard-panels it has no rear wheel mudguards. Both D7500 and D7506 models in Australia had mudguards, this tractor has none.

  • Rear end drawbar is much the same as for a D7500.

  • Governor-side flywheel cover is unusual incorporating a circular bolted-on plate similar to that fitted to post-war D7506 models but quite different to that fitted to D7500 and D7506 tractors of the same era.

  • As with D7506 models it has a generator mounted on the left-hand side of the gearbox. Electrical wiring switches appear to have been mounted on the right-hand cabin guard-panel.
  • It has a 6-speed gearbox as did D7506 models but not D7500.
  • The engine rotation indicator is of the type fitted to D7500 models.
