My L3830 will not pick up a full bucket of gravel. It will pick up about 3/4 bucket full. It's a 6' bucket, but I can't remember the the cubic foot capacity, it's not very deep.
A customer of mine works on Mahindras for a local dealer. He always has plenty of work to do, but I can't give you any specifics. I do know the older Mahindras are all pink now.
