get on a level surface both tractor and box blade. and level the box blade (left to right) using side link on 3pt hitch.
then you can adjust the "top link" on the 3pt hitch to tilt box blade forward or backwards. to adjust how much the blade digs in.
instead of just dropping the 3pt hitch. so it falls all the way down. keep it raised up some, when using the teeth. so you are not trying to dig into the dirt as much.
adding some extra weight to the box blade, like concrete blocks, lumber, scrap steel. etc... can help keep the box blade from jumping up and down as you attempt to dig.
if ground/driveway is like concrete hard / compacted. normally if you can break through the initial couple inches. it is smooth sailing after that. your goal with teeth, will need to get them initially started, and get them sunk in past that hard initial layer. so the tips, of the teeth. pull the hard layer up and break it into clumps. vs trying to get the teeth to slice through that hard top layer.
other words to above, take a large hershey bar say 2" wide, 7" long, 1/4" thick. you do not take a knife and try and cut it in half, but you break it in pieces. same like idea with the hard compacted layer and breaking the layer up vs trying to slice it up with the teeth on box blade.
you might try starting in the grass near edge of drive way. were dirt will be less hard/compacted. and then driving into the driveway.
and you might try extending top link as far as possible (within reason). to tilt the box blade backwards. when using the teeth. so it pops the hard layer up. err angle the teeth better so they pop the initial hard layer upwards.
instead of putting all 4 teeth down, just put the middle 2 down. and remove the outer side teeth. and it may help ya do the initial ripping up of stuff.
=======================
remember you can adjust top link to adjust how much the blade on box blade digs in. by tilting box blade forward or backwards. and yes with most 3pt dirt engaging equipment, one hand is normally on steering wheel while other is on the 3pt hitch leveler to raise/lower as needed. at least it is with me.
=======================
remember you will need to compact the dirt / gravel once you get things all back level. i tend to drive tractor, up and down drive way multi times, so tires go back over last pass a half tire wide. then will drive back over everything at 45 degree to 90 degree angle to initial passes, to further compact things.
the more weight i can get on tractor, the better to help compact.
