Short Game said:The Cub Cadet bucket hooks were there when I go it. I only added the receiver hitch. The receiver hitch got more use as a socket for my 4.5' square tube boom. It's useless for that on the LS because the roll-back is so gutless. I have lifted 300 pounds at the end of the boom with my Cub. I couldn't lift 50 pounds on that boom when I needed to with the LS.
Here are closeups of each bucket.
Okay, so it is just a larger hook that won't bind the chain...
You may want to have a dealer check your hydraulics. The curl feels a little weak to me too but I have no doubt that I could curl 300 lbs with it. It may depend somewhat on how long and heavy that boom is... Maybe they assembled your curl hydraulics with a hose backwards or a clog on one side...
