Need to change the tires/wheels on a W30XTC walk behind machine and have a few questions. Hopefully someone can help me.

I see how the front ones are attached, but no idea what's involved with the single rear drive wheel.

For the fronts.
Do you set the front nuts the same as you would any wheel bearing type of wheel?
Tighten nut till there's slight drag then back off 1/4 turn and install cotter pin?

Need a short tutorial on how to do the rear including a safe jacking procedure.

Thanks in advance!
