I had a l2 that I made a grain extension for. It would boost the capacity up to 260 to 275 bushels. The only 2 things I had trouble with was the bubble-up auger which I fastened in the upright position full time, the other problem was the vertical tubes on the steering axle broke on both sides after a while. I rewelded them and reinforced them with a strap iron. My l2 was a variable speed so I sometimes couldn't slow down enough if I encountered a rough headland and that's what probably caused them to break the welds. Make sure that you have a door to go through to get into the tank and take it easy and you shouldn't have much trouble unless it is bigger than that or you are harvesting 25% corn or higher
