As with most of these hybrid type instruments, ease and comvenience is somewhat traded for perfection. No, the cultipacker incorporated on the back of these machines, like on my Woods Seeder, does not work as well as a stand alone, 750 lb cultipacker - but I dont have to go back to the shed and get a cultipacker and I dont have to make another pass over the field. The single disk gang on my woods seeder does not stir up the dirt like my 1900 lb dual gang Mississippi Molene disk. But I dont have to make a pass with the disk and then go get planting equipment. Does a woods seeder plant as well as a no till drill - in most cases, no - but a no-till drill will not plant into hog rooting, smooth out your trail on the way to the plot, or fix erosion in your food plot.
Would I buy one of these supposed hybrid units if I was a row cropper looking to squeeze the highest bushels per acre - no. But, a lot of these types of equipment do a dang good job at planting food plots. I bought mine to reduce planting time over the old spray, disk, spread, and cultipack or drag method. Now, it is spray and plant, and not only is it quicker, it produces a better crop.
I cant get by with just a no-till drill. I cant get by with just a disk. Cant get by with just a spreader. But, These combination units can do a dang good job - especially when conditions are at least fair - but dont think they are going to be the best of all things.
