Greetings. Would anyone like to talk about a L7515 boxscraper? It came with my B8200 tractor and orignally I thought "no way" this machine would drag those teeth in the ground and I presumed to sell it ........ apparently from the tractor manual I was wrong -again.......So I have ordered the L7515 manual to learn what's up as I have a bit of mess where someone's backhoe "removed" some dirt from my build site. Specifically - can I presume to cut the ground with the teeth lowered and then remove them to "grade" the ground after? The "back" blade appears to missing some lock pins to hold it in a position.....? I'm sure the manual "en route" will tell me something - I was just wondering if anyone having used one had any tips or suggestions. Thanks - Chuck in Ohio
