Now that the weather in northern Illinois has warmed up slightly, I have decided to start to refurbish the Bulldog trencher that has been sitting in the shed for at least a year. Then I will be able to put it on one of my Bolens HT23's.
The first hurdle is going to be the double sprocket that fits onto the tractor PTO output shaft. The PTO output shaft is 1-3/8" 6 spline. The double sprocket needs to be 14 teeth for No. 60-2 roller chain (double stranded #60). Any of you folks got some ideas about where I might find such a thing? I have done Internet searches for weldable hubs, but the ones I have found with the required 6 spline bore are all for single sprockets, which does not help.
