Nice looking machine! I agree with you on the herky jerkys of these BH's for our types of tractors. I guess if we paid a lot more for some of the more refining capabilities of higher end units we could probably expect something a little more smooth in the hydraulic operations. Regarding your desires for a quick attach bucket and a hydraulic thumb I am with you, I would like the same for my 8B. I know that BXpanded has a quick attach for some of the JD BH's. I don't know if the 370B would have the same setup as your 375a. Backhoe Bucket Connector As far as a thumb goes I am not sure. I have a mechanical thumb from Bro-Tek but I would not buy it again with so many other options. It is even more cumbersome than other bolt on thumbs. But as you desire I want a hydraulic thumb for ease of use. Give me that and a quick attach bucket and I would be very happy.
