I was never impressed with the L Series structural frame design, especially at the rear. Chopper, fuel tank, engine, pan, walkers, and 1/2 of grain weight carried to the wheels on 1 spindly angle iron column on each side. Unsupported sections of the columns are short, but still, come on engineers. The dynamic twisting loads put on that frame while bouncing around with a full grain bin must be massive. Had they had todays modeling software to simulate these stresses, I bet there would be some other members carrying the load, so I add a few just in case.
I recommend never unloading partially. As brilliant as the rotating unloader design is it cannot withstand the load of swinging an auger full of grain many times.
I don't have a pic of the unbraced engine support but it's just a formed channel welded in place. Probably strong enough when welded properly but this machine had the new guy or dude in a hurry welding on it with QA at lunch. And no motor mounts were used to absorb engine shock but I'm sure they had a good reason why, just hope it wasn't cost related.
All in all though the frame was never a common failure element, but just barely so.
