Class Q

Class Q Traction Engine
- In 1913 The ‘Q’ Class traction engine was introduced, designed to be the ‘Rolls-Royce’ of General Purpose traction engines and five were sold in its first year.
- Only 14 traction engines were produced between 1913 and 1920″.
- They were sprung with something approaching automotive springs and fully lagged and had ring oiler bearings, Ross safety valves, feed water heaters, 180 psi for a single cylinder engine and had machine cut gears etc. They were only offered in 6hp size.
The down side is that they were considerably more expensive than the ordinary version.
