After a wait of over two years, from purchase to delivery, I was able to drive up to the freight terminal yesterday and pick up the Bulldog trencher set up for the HT series Large Frames. (Yes, I guess I am way tooo patient, but I recognized that the seller had some extenuating circumstances on his end, and we did stay in touch routinely over that time.)
Now that I have it, I can start to corral the pieces I will need to have or make for it to be fully functional and for it to look correct. I have the Bolens 540 PTO, but I will need to come up with the correct double row sprocket to go on the output shaft of the PTO. Plus the double row roller chain. New sprockets for the trencher chain itself (badly worn and broken teeth). Fabricate the proper top cover over the gear box.
Then strip the paint and paint it the correct orange. For some reason I don't get, the PO painted it red just before he sold it to me. Then get decals made.
This one will go on an HT23, or on an HT20D. (I might need to find more HT Large Frames, so I don't have to take extremely heavy attachments off once they are installed.)
