Engines got bigger

I started with a small oscillating engine a long, long time ago. Now I got involved with this roller, a 13 ton Ruthemeijer SCC, built in 1926.  There are minor repairs to do, so last Saturday she arrived to my home town at just a quarter mile from our home. I’ll do some work on this engine with  a couple off friends.   I am not her regular driver, just now and then as I stick to my STW agriculture, driving with loads of children, by the way did just under the 1000 km in 3 years.
As far as I know Ruthemeijer build SCC in license with the Burrell patent.
