Overseeding Timothy

Looking at possibly taking another field over that has been out of production for some time. Owner has been bush hogging it a couple times a year for the last 3 or 4 years. Think I will have any luck top dressing Timothy? Planning on manure this fall but just can't swing plowing it yet with our soil so hungry for lime. Was thinking manure this fall too dress Timothy this fall or spring? Or waste of seed? Obviously fertilizer in spring
