I know there are threads of some sort..but, I just bought my 1st striper/roller for my 21" Toro proline 22040 from Lowe's.....I just need some help/suggestions as far as use goes. I love the "striping" info. I've read on this site and am interested in doing it on my lawn 1st and then maybe customers' lawns?!?!? Anyway, what do U guys fill your roller with? Can U use this said roller/striper when it's wet? How much should that roller weigh when it's full? The instructions say to fill it w/sand or sand & metal pellets? I tried it w/basic dirt and it did nothing.... Also, I somewhat had to rig it up since the bracket from the lLowe's model did not fit exactly right, but now it lays flat & rolls true enough. Is there another site to purchase one if this Lowe's one is not the right size/model? Sorry about all ????s but I'm a novice in "striping" and need to learn. Any info/help would be greatly appreciated.
