Yes,i built it with intention,of possibly adding finer screens,Ill tell you guys something,THIS THING WORKS AWSOME !!!!!!!!!!!!!!!!!!!!!!!!!!!! i screened alot of loam,and gravel today.Once in awlile,i had to get off andpull off large grass root balls,put every thing else: sticks, rocks,stumps rolled right off Every two buckets id drive under and take away a load.Illtell you one thing,riser screws are tough.When shed start building up id bang the heck out off it with the bottem of my bucket,and shed unclogg itself,stayed on the seat most all day,never hurt it a bit.If i were to do over,i woulnt change a thing
