Model RangeEdit

BMB PresidentEdit

Main article: BMB President

The BMB president used a 4 cylinder 918cc morris industrial engine. There were three versions of this tractor one being the standard.

Orchard and Vineyard versions

There was also orchard and a vineyard models and the difference being that the air filter was removed and the exhaust was under the front grill on the vineyard and orchard model. The orchard was the same as the vineyard but it was 13ins lower so it could pass under trees. The next photo is of the vineyard version of the BMB president.


BMB PlowmateEdit

The BMB plowmate was the largest of 3 different size pedestrian tractors built by British Motor Boats who started importing American built machines during the 1930,s. The plowmate has a 2 foward and reverse gearbox and is powered by a JAP model 5 engine or a Briggs&Stratton ZZ engine both of around 6hp.

BMB HoemateEdit

Smallest of the BMB walk behind tractors, the Hoemate has a 2 stroke engine made by Brockhouse of around 1.5hp, it has a single foward speed and ratchet hubs to aid cornering. a flat belt when tensioned provides the drive from the engine to the wheels. like the other BMB tractors it could be fitted with many implements.


BMB CultmateEdit

The BMB Cultmate was the mid-range garden tractor produced by British Motor Boats, who were importing American Simplicity garden tractors before the war. Due to short supply of parts during the war years, they started making their own machines. The Cultmate has a BSA 3½ single-cylinder engine, a flat belt drive, with lever-operated tensioner acting as a clutch to the single-speed gearbox. Ratchet hubs made turning easier. As with many of these small horticultural tractors, many different implements were made.


A number of examples survive & are often seen in the Horticultural sections at working events, as well as in the tractor line up at shows. Only a few examples have registration plates as most worked in small market gardens and did not travel on the road. A number of examples are missing the serial number plate which is (was) brass & mounted on the bulked between driver and the engine on the tractors.

Serial numbers appear to be in several series;

  • STV 1206 - Built by Brockhouse Engineering (Southport) ltd. at Southport
  •  ??? 176406 - Built by British Motorboats Ltd at ?

Known examples include;
