The Magic Tractor
The best way to attract her.
The other day I built this little tractor using Teknik wheels, Märklin Flanged Sector Plates and a Meccano Magic Motor.

Close-up of the differential, built from a Märklin model book, using Teknik parts.

Here it is sitting in the fields, ready for action ...

... and here it is home on the farm with its "little brother."
