🚜🔥 QUESTION FOR THE GREEN IRON CREW 🔥🚜

Just dropped a new video and this one proves how a small issue can turn into a BIG repair. From deep engine work to cold field diagnostics, this job had a little bit of everything.

👉 What’s the most expensive “small problem” you’ve ever chased on a tractor or combine?
• Valve issue
• Sensor that wasn’t so “simple”
• Electrical gremlin
• Or something that snowballed fast

Sound off in the comments 👇 I read every one of them.

If you haven’t watched the video yet, go check it out — and let me know what part surprised you the most.

And as always…
keep that green iron moving! 💪🟢🥁

🔥 It’s LIVE! New Video Just Dropped! 🔥

What started as a small intake valve problem on a 9.0L turned into a BIG repair day.
Water pump, MEG input seal, X9 clean grain auger work, a freezing Bron 585 DEF fault call… and then the full cylinder head install to wrap it all up.

Packed video, lots of diagnostics, and a whole lot of “how did this snowball so fast?” 😂

👉 Watch here:

A tiny intake valve problem turned into a HUGE repair on this 9.0L… and it doesn’t stop there.
While waiting on the cylinder head to come back from the machine shop, I jump into an X9 clean grain auger fix, then head out into the freezing cold to get a Bron 585 tile plow back online after a DEF system failure.

And once the head finally shows up… it’s time for the most gruesome part of the job — torquing every last one of those bolts. 🤘

If you like shop projects, diagnostics, cold field calls, and big engine work, this one’s packed.

See you at 3PM — you won’t want to miss this one!

And as always… keep that green iron moving! 💚👊

We officially hit 100,000 subscribers!! 🙏💚 Thank you all for being a part of this journey.

Today at 3:00 PM (CT) the next video goes live — and we’re kicking off 2025 Winter Shop Projects with a massive S670 engine pull and tear-down. This one gets deep… and what I found inside surprised even me.

At the end of the video, there’s a special tribute to my buddy Jake — the reason this channel exists and the spark behind everything I do here. I hope you’ll watch it.

See you at 3pm. Let’s keep that green iron moving! 💚🔥

100,000 SUBSCRIBERS!

I don’t even know where to start… this one hits different.

When I created this channel, it wasn’t about numbers. It was a promise I made to my best friend I lost — to pick up where he left off, to chase something bigger, to inspire the next generation of technicians, and maybe… just maybe… hit 1,000 subscribers someday so I could get monetized.

Today, this community hit 100,000.

I’m honestly overwhelmed. Thank you to everyone who’s watched, commented, shared, supported, and believed in what I’m trying to build here. You’ve turned long nights, early mornings, busted knuckles, breakdowns, and field calls into something I never imagined possible.

I give glory to God, and a huge THANK YOU to Sloan Implement for supporting me, my family for cheering me on, and all of you for being part of this journey. I couldn’t do any of it without you.

This channel has been through a lot — and so have I — but one thing hasn’t changed: I love showing the real work that keeps agriculture moving.

Here’s to the next chapter.
Here’s to bigger projects, bigger videos, and even deeper diagnostics.
Here’s to honoring Jacob Moxely, who inspired all of this. This milestone is especially bittersweet without him, but I know he looks down from Heaven proud.

And as always — keep that green iron moving! 💚

Happy Thanksgiving everyone! 🦃🍁
Hope you all had an awesome day with family and friends. Just a heads-up — the new video drops TONIGHT at 6 PM! This one’s packed with diagnostics, wrench-turning, and a wild 8320 mystery that had me chasing power, grounds, and CAN until that thing finally told the truth.

Come hang out, drop a comment, and let’s keep that green iron moving!

Happy Thanksgiving everyone! 🦃🍁

Hope you’re all getting a chance to slow down, relax, and spend time with the people who matter most. I’m thankful for every single one of you who watches, comments, and supports the channel — you guys are the reason this channel keeps growing.

I’ve got a big video dropping Saturday…
Let’s just say an 8320 that starts… runs… and then dies turns into a full-on diagnostic battle. Plus a 9620RX that doesn’t want to throttle up, DEF work, ECU programming, cold-weather wrenching, and some Milwaukee tool action at the end.

Going to be a fun one. 👀🔥
Stay tuned — and as always, appreciate every one of you.

Keep that green iron moving! 💚🛠️
