John Deere 820 Haybine

[IndianaAg]

I have a JD 820 haybine. It had been cutting pretty well until this week. All of a sudden it started missing about a 3' section in the middle. There appears to be nothing wrong mechanically. It did seem to be digging a little in the middle. I reset the shoes to hold the cutterbar a little higher and slowed my speed down. It helped some (I think slowing down from 4-1/2 miles an hour down to 2 made the biggest difference) but I can't understand how it can look right but miss so much.

worn guards can look good but they have to much clearance between the knife section and
guards

Thank you for your reply! That's the next thing I'll check. This the first machine I've owned that has "no clog" guards. Any special way to check?

Look for rounded edges. what kind of tops are on your guards? I use the JD adjustable tops on mine and they work well. there may be others built that also adjust without bending

THere is a procedure in the manual for adjusting non clog gaurds... usually involves a feeler gauge.
