batwing

Anyone know what brand their Gearboxes are? Right hand one has played out on me. Called a dealer and they want $1,200 for a new one. Has to be a generic one available that would work.

I can't figure out how to get the wings leveled on my Modern Ag 15' Predator. The manual says to loosen the ratchets but that doesn't seem to do anything except make the linkage loose. What am I missing. Hard to tell from the pictures but the outside skid of the wings are about 8" of the ground...
