Keeping that Green Iron moving! Service calls on John Deere tractors

Here in this video, I was trying to level a concave on an S780 in the shop but the service calls come pouring in. First it’s a 8320R fan drive issue, then a 9560R with a restricted exhaust filter and a/c problem, a high crank case pressure problem on a 9620RX, and then back to the 9560R that just keeps battling me…

I'm not an engineer by any means here, but doesn't that variable drive fan system seem like it's a lot of moving parts? It also takes up a lot of space, I wonder why they don't go with a hydraulic drive motor like they do on the payloader's and what not? The tractor already makes hydraulic pressure and the fan could still be variable speed. I don't know I think that vari drive set up is cool, I'm just thinking it's a little surprising they didn't go a different route with that and save on the maintenance issues and the space at the front of the engine. Awesome video buddy

[@timbo19751975]

Anyone else staggered that a 3000hr engine (possibly) needs a new harness to fix an emissions issue?!?! I would expect 10,000hrs and 20years before any age related degradation of the wiring!!

[@ZKMasterTech]

I’ve put more on than i can count.

[@DrewChisholm]

I work on fendts and it's shocking how many harnesses go to shit

[@nickpersenaire4443]

Unfortunately they don't make them like they use too.

[@nbtmx1]

I wonder if silicon rubber insulation would solve the issue only problem is cost

[@RealJohnWayne]

Nope, you need to go down to your local Truck stop and ask a couple of drivers and mechanics about emissions systems on their trucks.

[@kenraterink]

It would be interesting to talk to the owner of that combine after they run it some this fall.. that thing should work 100 times better after being so out of adjustment like it was

[@nickpersenaire4443]

Hey Zeth, thanks for sharing a couple more service calls. You know it's that time of year again and a very happy birthday to your daughter.

[@ZKMasterTech]

Thanks!

[@JohnDavison-xi6zy]

I think Zeth you are worth your waight in gold. to John Deere.

[@cttoh09]

Grew up on a farm. No one in the family farm anymore. All equipment sold back sometime in the late 70's. Back when I was a kid NASA was the only place a computer could be found. Now working as a cardiologist. I have the crazy hobby of rebuilding old diesel engines. You are inspiring me to tackle a tractor from the 50's-70's. Love watching these videos. Thanks

[@jimclary7309]

Zeth great explanation as always. You always clarify what to do and not to do. You're technical skills are amazing. Keep the knowledge coming. Definitely catchya at the next one. Stay safe!!

[@williamorman4779]

Zeth,my son was 9yr old when he was running the 4440 ,next thing I knew he is 36yr old,cherish the time with your daughter,

[@davidnixon5832]

UFF DAH !!! i love it... i've been sayin' that since the last vice grip garage video i watched...at least you and i have that in common...

[@cubcadetsteve4148]

Happy Birthday to your daughter!!🎂🥳 enjoy when they are young because kids grow up way to fast.. I have twin daughters that are 15 and a son that's 10.

[@jerryhutchens01]

Watching your videos reminds me of when I was a kid. My dad worked for John Deere for 25 years. I loved going up to the shop and watching my dad working on tractors.

[@ZKMasterTech]

That's awesome

[@bengittus1836]

Saw Shinedown in Toledo, Oh a week and a half ago. Awesome concert! Loving the videos! Used to be a John Deere tech back in the early 2000’s, but turned out it wasn’t the job for me.

[@whathasxgottodowithit3919.]

3000 hours and new harness? that aint good

[@badzioch64]

Get yourself a vacuum guage. Using hose gauge not good enough. You’ll be able to tell if vacuum is good or if still leaking. Also invest in an electronic leak detector as well as leak detector soap to find leaks. I like Yellow Jacket stuff but whatever

[@BRPFan]

Another awesome video! It so reminds me of the many years working at the dealership! Happy Birthday to your little Girl!!

[@paulm6211]

You sure know your stuff. I enjoy watching and learning how you do things.

[@stevenicoson6670]

Thanks for another great video. It was interesting and enjoyable. Wow. Lots of variety on this video. Going from one thing to another with some service calls in between. Keeps you going for sure. As always, learned a lot. Never saw one of those belt drives apart. Interesting how you can update those drives. Found the leveling of the seave ?? interesting also. Spelling is probably wrong. Well, anyway thanks for going thru that procedure. Learned a lot on that. Thanks again for all the ins and outs on your variety of items today. About it for now. You take care and be safe. Looking forward to the next video. Thanks for everything. Appreciate the filming and editing. The Iowa farm boy. Steve.

[@donaldray9207]

Great job, hope you have a great time with your daughter on her birthday. God Bless

[@JerryLiedtke-i2q]

Hey Zeth, where did you get those AC line Vacuum plugs? Is that a JD tool?

[@arzamumma1202]

Viewed 4-26-22 from Illinois Hi Zeth, I have to say you really know the service approach to troubleshoot and repair, plus keeps a good attitude. If any JD customer seen your videos would want you to service their equiptment and know it was done correctly. Keep up the good work !!!!

[@ZKMasterTech]

Thank you!

[@dln11]

Another good one Zeth! I’ve got a Rogatot with a similar issue with the heater valve affecting the A/C. The valve on it is buried under the seat. I cut the heater line and put in a simple valve to shut off the heat side. That was about 4 years ago and never had to turn it back on. Wouldn’t be quite as convenient with a machine that runs in the fall or cold spring mornings.

[@WilliamPayneNZ]

When I worked in automotive I decided it wasn’t for me after being sick of working on things where everything was a pain and my not even big hands couldn’t fit anywhere. At the time heavy mechanic work like this and trucks never even crossed my mind. I probably would have gone this route had I stayed in the industry knowing what I know today.

[@lahubharose2023]

I am a indian farmer Your great video's I'm very excited your farming and mechanically Your compare indian farmer is very very technologies poor i when your videos saw

[@rosshall641]

Know today is this horsehair where on the wiring harness but there's 11 miles of wire on a combined today takes about 10 days to find the bad sports but you will find them

[@6Diego1Diego9]

This guy really knows his stuff, really good troubleshooting.

[@BruceBergman]

Do you have an electronic leak detector? I've never seen you using it. If the crank seal is bad or an prong it'll lead you right to it.

[@greggfrei6832]

Great video, just wondering what your Mobile A/C recycle setup is. I don’t have many a/c service calls that actually still have refrigerant in them upon arrival but it would be nice to have the capability when needed. Thanks for showing us your tasks, it’s interesting to see see how a fellow Ag mechanic operates.

[@farmshoffman8475]

Great awesome video zeth , keep That big green iron moving ! Working on a dreaded combine again lol 😂 working on a big iron horse is fun

[@donpeterson9282]

Zeth, where did you get your technical training and what type of education beyond high school did you compete to prepare yourself to become proficient at your job? I assume you have to attend some type of training (requal training) on changes, upgrades and new equipment. What percentage of your time annually do you spend in training and requal. Your knowledge is impressive. Very interesting and easy to along as you work. Well done, Zeth.

[@ZKMasterTech]

Took automotive in high school for two years, went to Wyotech for one year, worked as an auto tech for 4 years, was a master ASE technician, went to work for Sloans and trained with John Deere and earned master through John Deere university. I have to take at least 20 credit hours of training a year.

[@donpeterson9282]

Thanks. Many do not recognize the extensive training and requalification training master mechanics are required to attend. You have an excellent flow in your presentations and your videos are well paced. You have a pleasant speaking voice and your comments are conversational and comfortable to listen to and watch. You are very fluent with technical terms and discussions. I enjoy your videos, like your presentation style and impressed with your filming and editing. Learning is a life long process. Those who do not embrace learning warmly may pay a big price in years to come. I wish you well Zeth.

[@ZKMasterTech]

Thanks Don!

[@terrybenson3632]

Happy Birthday, little Miss ZK!!. 🎁🧁Excellent video Zeth. Have a great week.

The compressor shaft seal is likely leaking. I've seen them leak vacuum on automobiles but will hold pressure just fine.

[@valuedhumanoid6574]

Do you just work on green iron? I don't believe I have seen any red iron in your videos. Nice watching a real pro. You're one of those guys that this kind of work comes natural. Throw hard work on top on natural talent and you got a real force in any profession. I don't wrench on tractors, but the machines I do wrench on have many similarities and I have picked up a ton of nice tricks from watching these vids.

[@ZKMasterTech]

I work at a John Deere AG dealer so yes I only work on green.

[@chrisnewitt512]

Hey Zeth, keep up the good videos! Totally agree with you on how good Shinedown are, we have seen them twice now when they toured the UK.

Great video on a common issue on these deere tractors thanks for posting. My question is how have you guys at Sloan been able to stock the fan drive upgrade kit? I was told by my dealer in MN part is backordered and Deere has zero on hand.

[@ZKMasterTech]

Some we can get and some we cannot at the moment. I could get the driven for that 8R but not the drive. We have some in stock but it’s hit and miss.

Question for you,Just installed the new style driven and driver fan drive on our 9520r tractor,when the tractor is running high or low idle or anywhere in between the driver sheave is constantly opening and closing,not all the way but it is very noticeable,is just seems it can settle on one speed.I don't think that is normal what could be the problem.When it is hot our and I'm really working the tractor it can't seem to cool enough i'm constatly getting this code 1639.18 ECU.001. Fan is able to speed up all the way cause i can here it and see paint worn off to the edge of sheaves running tractor in custum mode engine rpm can can go as high as tractor wants it to but stays at 1850. Your channel is a wealth of knowledge thanks for taking time to do these videos.

[@ZKMasterTech]

Might have something wrong with the fan speed control valve if it is constantly hunting.

[@it_wont_work]

Is there any other brands that you could use

[@ZKMasterTech]

Yeah probably. Just have to make sure it doesn’t get hard or clog up. And handle high heat.
