The utility model provides a seed tedding device, including mounting bracket, barre, be provided with the crossbearer on the mounting bracket, the barre passes through the position adjustable ring andinstalls on the crossbearer, the mounting bracket pushes away that the flat -bed machine constructs, the tedding tooth installing respectively with crossbearer parallel both sides. Owing to has set up and push away the flat -bed machine and construct, when the seed of ridging carries out tedding, at first push away the flat -bed machine and construct and push away the tie with the seed of ridging, then carry out tedding by tedding tooth ridging again, the utility model provides a seed tedding device can make seed tedding more even, and efficiency is higher.
