I see many of you guys struggling with that situation.Also the Branson one lets you put the PTO in neutral. Then the PTO stub on the tractor will turn easily by hand, so you can line the splines up with the shaft you're attaching. Otherwise the PTO brake keeps it from turning. I have no idea if they did this on purpose and it wasn't something I knew when I bought it, but it's handy when hooking up a PTO chipper with a 220lb flywheel.
Did you ever try to shut down the engine and then hooking up the implement? In some cases, the PTO brake is activated by hydraulic pressure. With the engine not running, you can turn the stub by hand.
Ask me how I learned that.
