Petter engine dating
Failing to achieve the commercial success that they hoped, they adapted the engines for agricultural and industrial use.

In 1902 they produced the first agricultural tractor, powered by a 30-horsepower (22 k W) horizontal oil engine. This engine was called the Petter Handyman which was sold around 20% lower in price than the 'Petter Standard' and was sold in batches of 50 or more.

Its workforce of 500 men produced 1500 engines a year.Petter also manufactured the two-stroke M-type (petrol), the S-type stationary diesel, the A-type, and the A1-type, the only noticeable difference on the previous two being the position of the magneto: the A magneto jutted out, and the A1 magneto was tucked away underneath. Petter also produced another 'handyman, a 'cheap' version of the M-type.Petter went on to make a comprehensive range of air-cooled diesels, such as the PAZ1, AVA range, and the 3.5 hp AA1.The engine starts in ten minutes and runs, we are told, without attention.' The larger road wheels of the vehicle were 42 in (1.07 m.) in diameter.The twins continued to develop vehicles, the twelfth of which they entered to a competition at Crystal Palace in 1897, without success.
