Will this work to remove riding mower blades?

Depends on how tight the nut or bolt is, this ratchet will take it off. But remember it is not a substitute for an "impact wrench" where it hammers as it loosens, the ratchet does not do that. I tried it on removing break caliber brackets on the front of my car, it did not buldge the bolts until I broke them free with the impact wrench . If it doesn't, it's still a nice piece to have in your arsenal of Dewalt tools. ⭐⭐⭐

Is there a clutch or some mechanism to prevent stripping of bolt threads with 70 ft/lbs of torque? ?

What causes a bolt stripping is weakness in the material to begin with or improper torque (tightening) causing undue stress. The DCF512B has a variable speed trigger, therefore the user controls the speed. If the fastener is not able to handle the torque it could cause breakage.

Which DeWalt 20v batteries are recommended? Are there any limitations in this regard?

All DEWALT 20V batteries and all DEWALT 20V tools are compatible. Please note some tools require more power than others, so a higher Ah/Amp battery will provide longer runtime.
