Originally built in the early 1900s, the Wallis and Steevens 3 Ton tractor was a popular engine for light haulage work. Their compact size and maneuverability meant that they could access most places where a horse and cart would have previously been used. As the use of steam haulage increased, the infrastructure modernised to allow access for larger vehicles, as such these compact engines fell out of favor with operators and only a few survived into preservation.

​

A well advanced project, this little steam tractor offers an interesting opportunity to build your own new full size steam engine. Appealing to both full size and miniature steam engine enthusiasts, it should fall within the capabilities of those experienced in larger scale model engineering.

The boiler has been built by well known and respected John Rex Model Engineering. It is of fully welded construction with the hornplates bolted on separately.

 

A lot of time and effort has gone into making the boiler look of original riveted construction.

As can be seen in the pictures the quality of the workmanship is to a very high standard throughout.

​

Parts completed so far include:

​

• Smokebox and door ring, Chimney base and cap.

• Perch bracket, and all steering gear.

• Front & Rear wheels.

• All shafts and bearings, including crankshaft.

• All gears made, most are fitted.

• Gear change mechanism and levers.

• Reversing lever and regulator, lifting links and arms.

• All eccentrics and straps.

• Connecting rod. 

• Also, many other items including gauge glass fittings, whistle etc. 

​

The final major casting required for the build is the cylinder block. The core boxes are made and cylinder pattern is CAD drawn and progressing.

The patterns used to build the engine have been professionally made, and are not included in the sale but could be for sale separately.
