thats what i was thinking needs something heavieryeah ATf is not meant for gear appilications, when I had a bobcat 500 I used universal tractor fluid and never had a problem, it is for hydro and gear appilications.
My M600 specifically calls out ATF, I think it is mainly because it has friction clutches that share the fluid. also mine has no gears, just chains and sprockets. I was thinking the 610 is almost exactly the same? I bought 20 gallons of ATF to put back in.thats what i was thinking needs something heavier
same here with a m600. It called for atf because of the clutches. And actually toward the end of my ownership of it , we were using utf with no real signifigant change in operation. guys at the hydro shop said it would be cheaper to run that and there was no real difference in utf when it came to the friction clutches. Take it for what its worth.My M600 specifically calls out ATF, I think it is mainly because it has friction clutches that share the fluid. also mine has no gears, just chains and sprockets.
