It's probably a simple matter of adjusting the brake shoes. As already noted, you need to be able to turn the drive shaft to get a feel for the correct adjustment. I just lift the rear tires off the ground and support the MH with jack stands. Also you'll need to have the transmission in neutral for the brake to be in the released mode. If memory serves me correctly, you'll need to have the ignition key in the on position also. Look at the brake drum and you'll see a removable clip. Remove the clip and turn the slot to the top to see the adjusting star. I adjust the shoes as tight as I can and then back off the adjuster until the brake drum turns free.
