Not sure if it was just a UK thing but the earlier model had the lights on the outside of the radiator cowl here in Australia. The tacho didn’t work that great from new either. Hydraulic 3 pt linkage not as good as some other tractors of similar vintage but still not bad. I replaced the head gasket on ours in 1970 while in 3rd year at high school. Still a better tractor than a TE20 🤣🤣
I had looked at the options of updating to a screw on style without the central bolt but decided to just stay with the original bolt through as replacement bits are readily available in the UK.
