Pine bark is relatively slow to decompose and may make tilling more difficult. So it may be best to rake the mulch off to the side before tilling. The bark mulch could then be re-applied after planting next season.
Or you might consider using the pine bark in your landscape beds around trees, shrubs, or perennial flowers or between beds if you use raised beds. Finer-textured mulch such as clean hay, straw, grass clippings, dry tree leaves (except black walnut), pine needles, can be tilled under in the garden.
