In this video I will show you how to replace a rotor belt on a John Deere S680 combine. The procedure is very similar for all John Deere rotor combines but it is definitely tougher on the newer combines because there is no room!
I don’t even own a 680 but I’m watching and commenting and liking every one of these vids. We need more mechanics like you showing us farmers how to do this stuff. Thanks man!
I don’t even work on JD and I’m the same so many little tips and techniques quickly became my favorite Heavy Equipment channel i also love TekamoHd but limited on what jobs they Can film
Hey Zeth, I've got a question, on the right side of the combine there is a cut out that looks to be for a bearing on some sort of extra attachment, it can be found just behind the discharge beater belt and just to the right of the the manual sieve and chaffer switches on the back, I was wondering what the cut outs are for.?
Those are for additional components for a premium residue option. They can choose whether to wind row or chop. But the cut outs are on all combines. Yours just fell out and they can be patched back up if it's an issue with residue leaking.
How would I go about patching it up.? It causes residue to build up between the discharge beater belt and the frame of the combine, that causes the belt to skip a groove in the front pulley
When I do rotor belts before I back off the turn buckle I jam a socket between the sheaves saves a lot of time and is easier on the belt less of a chance of ripping a chunk off rolling it on the sheaves.
Its just interesting to see anything that is ag related, something I’ve never tinkered in, but just larger iron then the automotive I’m used to. The format is perfect, almost like a how to, but more what you are thinking out loud, which is perfect. Anything day to day like this is good, even if it’s simple maintenance or common repairs
Hasn't changed much from a 9750. Had one break apart in the field on me. Not near as clean and engine was nice and hot still. Along with a bent shield over the driveshaft perpendicular to the belt that we had to bend back. We have pretty good relation with the JD techs in the area and gave us the same tips you had here, but a video would have been better for sure. The video brought back memories. Great content, been enjoying watching your various videos. If I had a dime for everytime I've heard someone say something about if an engineer had to work on some of these designs. Lol
Engineers never think about the people that gotta fix the stuff I think about this Almost daily why didn’t you just .. why not a hinge here .. why not a sliding drawer here… I don’t have letters in from it my name so what do I know 😂
I worked in the automotive end for fifty years I thought the automotive engineers came to work with a coloring book and crayons but after watching your videos I’m sure that’s true with JD engineers
Thank you! I wish our s680’s were tier 2…way less to go wrong engine wise. We just delivered a brand new s790 and it threw a rod out the side of the block with 5 hrs on it. What a mess!
What led you to replace the belt, was the belt cracked, or was the combine not reaching a certain speed? Is there a belt width spec or gauge like with the tractors?
Just replaced one in the field last week. A couple wooden wedges on the driven side helped open it just enough to get the belt back on. Good videos, keep them up sir!
I just love all your videos Zeth. I sent my dad links to your channel. He’s 85 now and retired from farming (last tractor was a 4640 and a 6600 combine). I grew up and ran JD equipment, I learned on a 4010 tractor and 55 combine but instead of farming I went into the service, however I like to keep up with all the latest things. I often wonder if instead of doing a career in the service if I’d have been successful at farming. The machines are sooo big and complex now it seems you have to go big to make a go of it. Just wanted to say I admire your skills and wish to thank you for these videos, they’re well put together and interesting to watch. I’m sure my dad will enjoy them too.
Thanks Zeth, in the aero engine industry, some manufactures now have systems whereby the engine can send data back to the head office about its performance, so that when an issue ariese, the plane can schedule maintenance or be grounded in safety situations. Do you know if John Deere has a similar system? Perhaps, with all the sensors and on board computer, it could analyse the data and send a text to your office, order the spares and advise the operator that a maintenance issue has appeared and you can arrive, with the parts and hopefully fix things?
Very informative Z. 17 years ago, we had to replace the rotor belt on a 9750 STS in the field. We were able to have it installed and adjusted quick! ( other combine only did 1/2 mile up and back). That was due the extra room in those machines, belt broke and gone, and knowing all the tools needed and having done once before. Never needed to change it on S680’s or S780’s we have had since
New subscriber interesting content in all your videos. Thanks for showing. Younger men need to get in your trade. Does your company train the younger techs? Thanks
Hi, you made it look easy. You have done it before, how often in the field ? Very hot, dusty, chaff, straw plus probably an angry driver or farmer, but at 6'4" if I was the farmer, I think I would give a hand and take up the offer of a winter service. How was that cracked belt discovered, luck, inspection or a service ? Great videos, it's for real. Thank you.
I would like to see anything related to the 5M tractors if you got some of them around. Thanks for these informational videos and ceep of the good work.
Hi, Looks a reasonably easy belt to change, all thats missing is the heat from the engine, all the dust and the farmer asking how long its going to take and how much the belt costs!!!
That's kinda cool seeing that drive in action since you can only imagine seeing the same thing going on in the new CVT transmissions. Like a sneak peak into the forbidden realm. :)
If I can’t get rotor shifter in low.how can I move rotor to do so when I can’t reach around the exhaust filter.and get a good grip to turn rotor. Thanks
It seems like these newer generation John Deere are braking down a lot. I used to work at Caterpillar in Aurora IL and as the new wheel loaders where coming off the line a few per month would head to "R" bay for repairs and mostly it was all electronic issues but some were for mechanical but mostly all electronic
I work on them often in harvest season and I scan agree on engineering part lol fucking Engineers they got two goals 1. How can I make this difficult 2.How can I make it almost impossible to takeoff.
