First let me say I have done alot of reading but not found all the answers. I am working on an H, changed engine fluids and got it started. Now I would like to drain and change the rest of the fluids. I found the hydraulic fluid fill and drain and that I should use 6 Qts of 30w oil. I also found the drain for the transmission(back of the tractor) drained it (UGH!!!) and that it will require 24 QTs of 80W90 filled thru the plug on the deck. I also seem to have another drain and fill assciated with the belt pulley transmission??? Fill on top and drain under tractor (3/8 rachet plug) I think????? Am I correct?? What goes in here and how much? I will try to attach a picture that shows what I think is the fill (plug on top above the hydraulic fill). Thanks in advance for any help.
