    Cat 308c CR

    Does anyone know how to switch a 06 Cat 308C CR from a hammer to use a thumb? The foot pedal is currently only pressurizing one side of the lines at the stick. From what I can tell, the other side looks to be plumbed as a return. Thank you

    KX91-3 pressure relief valve

    I recently bought a kubota kx91-3. It is plumbed out to the stick for attachments. I bought an aftermarket thumb but do not know if I need a pressure relief valve or not. I called my local dealer and he didn’t seem to know what I was talking about. Any guidance is greatly appreciated.

    JCB 3CX (1400B) Titan Thumb Install

    So I ordered a 36" Titan thumb to mount to my JCB. The thumb seems very heavily built for one that is cheaper than dirt (literally cheaper than a load of dirt). JCB's extra dig design however poses a few installation challenges. I guess I have a few options. The first is to weld the thumb...
