Speaking of the new YouTube channel — here’s a video I uploaded from yesterday’s repair! 🔧🎥

This Cat 287B lost its drive due to a failed drive coupler. I brought the camera along and documented the repair from start to finish.

This is exactly the kind of content I plan on putting on the Prentiss Iron Co. YouTube channel — real repairs, real problems, and an in-depth look at what goes into keeping heavy equipment running.

Check it out, and if you enjoy it, please subscribe! I’ve got plenty more videos coming.

BIG NEWS — I finally started a YouTube channel! 🎥🔧

Over the last few months I’ve been trying to do a better job documenting the work I do every day. Heavy equipment repair is a side of the industry that most people never really get to see, especially what goes into diagnosing and repairing these machines out in the field.

So I decided to start Prentiss Iron Co.

The channel will be focused on real-world heavy equipment repairs, diagnostics, field service, equipment projects, and everything else that comes along with keeping iron moving.

My goal is to make longer, more in-depth videos where I can actually show the entire job — what failed, how I diagnosed it, how I repaired it, and hopefully share some useful information along the way.

I’m still learning the filming and editing side of this, but I’ve got a lot of cool projects and repairs coming up that I’m excited to share.

If you’re into heavy equipment, wrenching, diesel engines, fabrication, or just like seeing how this stuff gets fixed, I’d really appreciate it if you checked out the channel and subscribed.

And as always, thanks to everyone who follows along and supports what I’m building. There’s a lot more to come!

I came home from work today and found this letter in the mailbox, and it meant a lot to me.

Heavy equipment repair is how I make a living. It keeps a roof over my family’s head and food on the table. But more than that, I truly believe it’s what I’m supposed to be doing. I love this work.

Being a field mechanic isn’t an easy job. We work outside every day—whether it’s 105 degrees or 15 degrees. We work in the mud, snow, rain, landfills, quarries, construction sites, and wherever else a machine decides to quit.

And a lot of the time, there isn’t a manual telling you exactly what to do. You have to understand how the machine works, diagnose the problem, think your way through it, and sometimes re-engineer a solution right there in the field. Most nights my brain is just as tired as my body.

Then I go home, put work aside, and spend time with my family. Once everybody is in bed, I usually open the laptop back up and work on the business side of things.

I don’t think most people realize what field mechanics actually do, and that’s a big reason I’ve started sharing more of my work online.

My goal with these videos isn’t just to show broken equipment getting fixed. I want to show what field mechanics deal with every day, share useful information with people buying and owning heavy equipment, and hopefully help other mechanics learn something along the way.

I’m not the best mechanic out there. I’ll never claim to be. But I care about what I do, and I try to treat every customer’s machine like it was my own.

There’s also a huge need for people in this trade. I went to vocational school and loved it, and I’d highly recommend that path to any young guy or girl who enjoys working with their hands and figuring out how things work. Nearly every business I talk to is looking for mechanics. I could hire three more guys tomorrow and keep them busy.

And to my customers—if I don’t get to you as quickly as you’d like, I truly apologize. The phone rings constantly, and field repair comes with a lot of emergencies. I’m usually just straight out trying to keep as many machines running as I can.

Then every once in a while, you find a note like this sitting on the truck.

That makes the long days worth it.

Thank you to everyone who has followed along, watched a video, shared a post, recommended me to someone, or trusted me to work on their equipment.

There’s a lot more to come.

I’ve always avoided the refuse side of heavy equipment repair… but sometimes you don’t know what you’re getting into until you get there. 😂

I knew I was heading out to work on a Cat D6T. What I didn’t know was that it was sitting in a landfill.

And of course, it wasn’t going to be an easy one. Drop the skid plates and replace a suction line running from the bottom of the transmission to the charge pump—all while working in exactly the kind of conditions you’d expect at a landfill.

But we got it done. 👊

While the customer’s mechanic ran for parts, I was able to knock out several other repairs on the machine as well. By the end of the job, we’d earned the trust of another large outfit to help support their mechanics and keep their equipment moving.

That’s what it’s all about.

Another one back to work. On to the next!

I’m back! Took a much-needed vacation, did some fishing, and spent a great week at the beach with my family. It was definitely good to get away and recharge for a bit.

But now it’s back to business!

I’ve got a few longer videos I’ve been working on while I learn the editing side of things, and I’m hoping to have the first one up by the end of the week. I’ll also be putting together some shorter videos to share here along the way.

Lots of equipment, repairs, and projects coming!

And on a completely unrelated note… anyone need an extra deckhand for some tuna fishing? 😂 I think I’m hooked now. 🎣

This old iron is coming back to life!

Koehring 1066 with a 12V71TT two stroke Detroit diesel.

We’ll be firing this machine up, repairing a few broken track links, and preparing it for transport including removing the bucket, stick and counter weight.

I posted a few videos last week and it seemed to draw some attention. So I have been shooting videos on a few larger projects that I’m currently editing. Those will get posted over on YouTube. You can follow that page at http://www.youtube.com/

I’ll still post some shorts here and possibly break up longer videos for some Facebook content. But I’m also looking for cool heavy equipment related projects I can be part of and film. My goal is to provide in depth content on diagnosing , repairs, pre purchase inspections, and all things related to heavy equipment. Please shoot me a private message with any leads, and equipment that would be good for will it start videos, repairs you haven’t been able to figure out, etc. thanks for watching and keep an eye on more content to come!

This CAT 374F came to us for some much-needed undercarriage repairs—a project we tackled over the winter.

After spending its entire life building jetties in the ocean, the tracks had definitely seen better days. We tracked down a solid set of used rails, replaced the track adjusters while everything was apart, added a link to get the fit just right, and spent the day swapping it all over.

It's always satisfying bringing hard-working iron back to life.

Customer complained the fuel truck is no longer pumping fuel. They even told me it had half a tank of fuel in it. Always do your due diligence, start with the basics, and keep it simple.

Checking out a CAT D8N today. Customer recently bought the machine so we are working through a few bugs. This is just the beginning of this machine. More videos to come. We’ll be doing a blade and push arm rebuild and re doing the pins and bushings on the nose cone.

UPDATE: this is my first video. I didn’t film every portion of this repair. Yes the master switch was on and yes I load tested the batteries. That’s why I jumped right to replacing them. I’ll be more thorough in future videos. Thanks for watching! Also look for longer videos posted on our YouTube page at
