That's a different design than mine and all the rest I can recall seeing. It has the tines in front and looks like a smooth edge on the rear. Never seen one like that and it may be a good design especially for a final smoother grade. Mine is made for busting small clods then you have to smooth for a final grade if you need it. It has the tines in front and rear and the spiked roller like yours.
This is not a one pass and you're done tool it takes running over the area several times to obtain results but heck I like seat time anyway.
