That does look like a Gutbrod ride-on mower – or identical to a Gutbrod. Is there any Gubrod identification and can you tell the original colour?
Your tractor looks complete, although I cannot see if you have the mower deck. It is a reasonably scarce machine and the 1966 engine code seems a likely date.
I recall the mower deck would possibly have been 24″ wide. It would have been side-discharge by the front right wheel.
There can be a slight difference in the seat spring, bonnet design, engine size (4 or 5 hp), gearbox can be 1 or 3 forward speeds, and tyres can be pneumatic or the semi-pneumatic ones which essentially are just hard rubber.
On the Gutbrods, the steel seat, steering wheel, engine, mower deck and wheel centres would have been painted white. The rest of the machine, apart from the unpainted gearbox, would have been red.
Pictures attached.
