Ok...guess I'm just bored with winter and am thinking of the coming harvests this year.... I've wondered for a while, and I know you guys can help me out. I'm trying to figure out how to set the L3 to perform the best it can. I have a few questions and "what if" situations, so I'm hoping I can get the solutions before I'm in the field scratching my head. As always...any thoughts/opinions/advice are appreciated. Question 1: There has always been some wheat loss with the L3, and never a prefectly clean sample. I know there has to be some loss. I don't think you could ever get a 100% perfect bin sample without some loss, but I want to minimize my loss. If I have someone throw a piece of cardboard under the combine while I'm cutting, then we analyze what's on the cardboard, how do I tell if the grain is carried over the shoe or carried over the straw walkers? If it was from the shoe, I would say either open up the chaffer a little bit more or dial down the air a bit (depending on how much chaff is in the bin already). But if it's carried over the walkers, what do you do? I've heard some people say you can raise the end of the walkers up to help, but I've never done that.
There's also the question about balancing shafts. The combine throws chains, and I've always blamed it on my uncles' refusal over the past 30 years to oil the chains daily. The big shoe sprocket on the left side of the machine is pretty worn I think. The chain has a lot of side-to-side movement. They put a new fan double sprocket on a few years ago, and the chain is pretty tight on that one. Not much side-to-side movement. However....that's not the chain that always gets thrown. The chain that always gets thrown is the chain that links the bottom clean grain elevator shaft and the fan. Since the fan sprocket is new, I'm wondering if maybe the clean grain elevator shaft is out of balance. How do you balance a shaft? The sprocket is worn, but it's not as bad as the shoe sprocket I mentioned earlier. A guy told me once maybe the sprockets were not aligned properly, and I guess I need to check that. Is there a proper way to do that, other than eyeballing it?
Also....we've put new chains on, and that doesn't do much good. I know the worn sprockets turn a new chain into a shot chain really fast. I'm just trying to figure out what my next move should be. I want to make this combine great again. We're going to have wheat, milo, and canola harvest this year, so it'll be a busy year for the ol' girl!
