Lanz Models Numbering Systems

Following requests from visitors to this web site who are confused by the Lanz model numbering system this page attempts to provide information about this system. The information below is collated from Lanz Australia Service News of January 1958 and details provided by Lanz expert Herby Voigt to whom I am indebted.

In Europe Lanz tractors are designated by a D number such as D7506; in Australia however an alphabet letter is used based on the tractors horsepower. Consequently australian visitors to this web site have difficulty with the Lanz Pictures pages where tractors are mostly identified by their D number.

Lanz Bulldog D Numbering System

All bulldog tractors have a D number (i.e. an order number). The D is followed by 4 numbers from which the tractor model can be identified. The first two numbers indicate the horsepower of the tractor and the last two numbers indicate the version or model. The table below shows the meaning of the first two numbers for prewar bulldogs:

D Number Horsepower
D45 15 HP
D35 20 HP
D75 25 HP
D85 35 HP
D95 45 HP
D15 55 HP
D25 55 HP (Express)

The last two numbers mean the following:

Numbers Meaning of Numbers
00 3 speed farm bulldog
01 3 speed farm bulldog with complete electrical outfit
02 3 speed farm bulldog with electric lights
06 6 speed tyred farm bulldog with complete electrical outfit
07 6 speed tyred farm bulldog with electric lights
11 6 speed traffic bulldog with complete electrical outfit
16 Export model version of 06 (above)
50 Basic crawler
61 Crawler with complete electrical outfit
31 Express bulldog without driver's cabin
31/38 Express bulldog without driver's cabin with power winch
39 Express bulldog with driver's cabin
39/38 Express bulldog with driver's cabin with power winch

There were also some special models as shown in the table below:

Model Number Description
D5506 16 HP all-purpose farm bulldog
D7506 26 HP vineyard bulldog
D7006 20 HP Pure Gas Bulldog (Gas Producer)
D8006 32 HP Pure Gas Bulldog (Gas Producer)
D9006 40 HP Pure Gas Bulldog (Gas Producer)
D??32 6 speed traffic bulldog (1949 - 1953 )

The later model bulldogs built after the war (semi and full diesel) were designated a different series of numbers. It also appears that the numbering system was applied somewhat arbitrarily and inconsistently.
