Evening all, My first post.... I have two drums/ barrels that i can use to build a counterweight for my ck35 hydro. One works out to 312# with concrete and the other works out to 540#. The rear tires were loaded w/ rim guard to somewhat over half full according to the dealer. The rear end gets a little light with wet dirt in the bucket and that tends to make things just a little squirrely going over uneven ground... even traveling very slow! I understand that 540 is more counter than 312 but I don't know if I even need quite that much?? Any thoughts?..... Thanks, arcspark
