Just bought a 87 bobcat 743 with grapple and stump bucket . The previous owner bought it with a bad motor and put in a kubota v1902 to replace the 1702. My problem is with the auxiliary hydraulics. I removed the small bolt on the right lever and it's really sloppy, I don't see where the lever when pushed to the front and moved left and right moves any thing in the linkage to where it will run the aux hydraulics. Admittedly I have not hooked up the grapple bucket because it's missing the hydro quick connect on the lines. I need to buy some and check to see if it works. Looks to me like there's something missing to connect the right lever to aux hydraulics, am I wrong? The grapple was never on this machine, he picked it up for another one he has but ended up selling it to me with this machine.
