Just got a box blade for my drive, thinking about dragging the whole 14 acres on a very light tilt - just to knock down the ridges
You can try your Box Blade. Smoothing rough pasture usually requires several implements used in succession.

So we have about a 3 acre field that is currently a mixture of grass and weeks that we mow at 3.5” high. Problem is it’s a old tobacco field that still has some of the ridges left in place from the previous owner. They are not terrible but enough we need to mow slow or it makes you sick going over them. So my plan is to spray round up next weekend then by end of month start disking and breaking up the soil like in a X pattern or going against the ridges. So after This what is the best implement to smooth and even everything back out? Once done I will use a cultipacker to smooth and press the dirt then spread new grass seed.
A week after you spray, mow as short as possible: "scalp."
Few with Disc Harrows adjust them after putting them to use. If you first process the field two or three times (depending on the weight bearing on each of your disc pans) to loosen ridges, then adjust gang angles less aggressively in increments, the disc may meet your needs solo.
Moist soil will make your project go faster.
Adjust Top Link to vary disc weight distribution. Shorter = more weight on front gangs. Longer = more weight on rear gangs.
More weight on front disc gangs throws dirt OUT. Use on ridges.
More weight on rear/wider disc gangs gathers dirt IN. Straddle the swales.
The faster you disc the more dirt is moved.
As the field is smoothed, adjust Position Control hydraulic lift so disc is in lighter contact with the soil.
Most pasture grass roots penetrate 7" to 9". Most pasture grass roots survive vigorous disc processing if rain arrives not long after.
If you elect to overseed I highly recommend a <$10.00 soil test and soil amendment per test result(s) prior to seeding. You need to inform test agency what variety of grass you intend to plant for optimum amendment recommendations.
