We run a 20ft 800 and a 25ft 8000. Have lots of experience with both heads and they dont cut quite as low as some other brands I have noticed but I dont have a problem with that. We rarely will ever sweep a rock in and we dont let many beans in the field on the 2.5 in stem that might be left. The tall flighting is a huge help, again we rarely have feeding problems. Cut 1500 acres of beans this year, running in rocky hills to flat flat bottoms, tall to short beans. And gleaners fingers dont break like other brands, they will bend if you catch a rock but have never seen one break and go through the machine. We have guys that actually plugged up augers and elevators with the other colors. And ask a guy with an sts what happens when they break off an slip though the combine, bing bang rumble rumble crash. I realize they could use improvements but the other guys will improve just as gleaner does, deere had plenty of troubles with sickle heads and electrical problems this year. I guess I am just so happy we had a good year, after 3 years of drought in a row. Bless you all and I hope things get better for ya, I know they did for me.
