BIRDIE FOUNDRY created its cast iron foundry activity in 1850. At the origin of its creation, the Birdie Foundry family worked already and mainly for the agricultural market by manufacturing agricultural rollers today called Cambridge, croskille and croskillette
Birdie Foundry began manufacturing his first farm tractor mass, also known as the tractor mass jerrycan, in 1935, 44 years after the creation of the first caterpillar and steam tractor that was invented in Russia in 1881.
In fact, the first wheeled tractor was invented in 1909 a few decades after the first model was created.
The tractors became more and more heavy, and it was necessary to ballast the front and sometimes the rear of the tractors.
The first jerrican tractor mass had a weight of 15 kg. Nowadays, relative to the evolution of the power of agricultural machinery, there are counterweights that can reach a weight of 2,000 kg.
The additional tractor weights are manufactured by our company for weights ranging from 19 to 110 kg. We manufacture cast iron tractor masses (also called jerrycan mass due to resemblance to a jerry can) for Agco, Valtra, Massey-Ferguson, New Holland, Case, Claas, Renault, McCormick, John Deere, Kubota, Same tractors, Deutz Fahr and also tractor weights for tiller, which we call micro-tractor, we also have wheel weights and produce large masses of over 600 kg.
The jerrycan masses are melted at a melting temperature between 1480 ° and 1500 °, they are made by footprint in a sand mold following a model of aluminum or resin.
Our tractor counterweights are painted according to tractor brand paintings, we can deliver all over France and in all countries. We have a large stock of tractor counterweight do not hesitate to contact us for any request.
