I want to SECOND above comment from Roger/94BULLITT, above.
When backing up to an implement to attach it, without some means to hold the lift arms in a spread position about as wide as the draw pins you want to slip the lift are 'eyes' onto, arms want to snarl on some part of the implement. Before ordering telescopic stabilizers from Stabilworks I used rebar, pounded into the dirt, to stake the tractor lift arms at the appropriate width. It was a pain, but effective. Also, I often lost one or both of the hairpin clips which secure the stabilizer turnbuckles on the B3300 (but not on all Kubotas), which was also irritating.
Telescoping stabilizers making changing equipment much easier. I have a Pat's Easy Change System here but once I installed telescoping stabilizers Pat's seemed redundant so I still have Pat's adapters in the packaging. I may install Pat's yet......one-of-these-days.
Like riding a two wheel bicycle, it takes time to figure out the optimal technique for hanging each piece of equipment on the 3-pt hitch.
You will find connecting the PTO shaft to the tractor, on PTO powered implements, ALWAYS a trial.
