I am a new to this site. just bought an iseki tx1500 or guy told me it was a g174, and he said hyd fluid was 80 wt that you put in back top of rear end. I never heard of 80 wt used as hyd fluid. know nothing about tractor. hyd snow plow operates good and so does three point hitch also would like to buy good manual for it. thank you for any help.
