From day 1 my rear wheels on mower deck have created a problem! If there the least amount of moisture is in the grass the rear wheels will form perfect grass rings on them,then as you turn it releases them. making the lawn look like you have birds nests in it! So I purchased a spare set of front radiused wheels and put them on the back too! My problem seems to have gone away! I hope this helps somebody else out there in mower LAND!
