I have picked up a 'sulky seat'/ride on attachment for my atco standard. The seat is stamped 1923 so it is a similar age to the mower, although I suspect it is actually from a Dennis. Anyway I am wondering how the original atco unit attached. Does anybody have one that they could post a picture of? The plan is to make an interfacing bracket to replicate the original detail.
Ill post a video of the completed seat and bracket on youtube when it is done.
