Thinking of getting a Poly Lawn Roller (any input appreciated)

Out back weedwacking a couple days ago, & I noticed a LOT of frost heave thru my lawn.. Bumps & humps.



Guess it's time for a Lawn roller.. Been looking at a Brinly & also an Agri-Fab roller. Both are Poly rollers.



Any thing I should try & avoid or any tips would be greatly appreciated.. This is to be pulled behing my Toro ZTR...
