Wooden Tractor

This wooden tractor was made to a scratch-built design.


Wooden Tractor









The scale of the tractor was defined by the front wheels, which were 2" in diameter and were purchased from Woodworks Craft Supplies.

The chassis was a simple profile cut from a 20mm Oak board.

Rear axle holes were drilled in each side.










The lower half of the cab was made from two 20mm Oak sections laminated to together.

Once glued in place, the cab sides were sanded to the same dimensions of the chassis.









The upper half of the cab used some laminated dark and light wood to add detail.

The cab roof and pillars were made from darker wood and the windows from lighter wood. These components were cut in one setting on the band-saw to ensure they were all the same thickness.

A block of softwood was cut to the same size as the cab base minus the window thickness. This block had angled sides to give the cab the correct profile.









The upper cab assembly was glued to the lower half and the corners were rounded with a file to give a smooth appearance.









The front axle housing was a 20mm square beam cut to length and with holes drilled in each end to take the front axles.

The 2 underside edges of the beam were chamfered at 45 to give a better profile.









4 pieces of wood were glued together to form the bonnet and engine assembly. The engine was made from a darker wood and was recessed by 10mm each side.

All the corners were generously radiused, to give a rounded appearance and the width was sanded to match the chassis.









The front grill was formed with parallel cuts on the band saw.

The rear wheels were made from a block of 20mm thick dark wood.

The wheel centres and diameter were marked out and then the basic shape was cut using the band saw.



The rough shape was centred in the 4 jaw chuck on the lathe. The centre hole was drilled to suit the axle dowel and the hub was recessed to give the wheel shape shown on the right.









An arbour was turned to suit the axle hole and each wheel was secured with a nut and a fibre washer to prevent it slipping.

In this setting the outside diameter was turned and the wheel sanded smooth.

A sharp point tool was used to add some tread detail and some grooves on the face to represent the wheel.

Originally it was planned to have a more 'off-road' treat cut using the band saw, but the straight tread was much easier to machine.

After assembling the above components the tractor looked like this.......

A towing hitch was added at the back and a small towing eye at the front so the tractor could be pulled with a apiece of string.

The rear towing hitch base could have been incorporated into the chassis component, which would have been much stronger
