Has anyone ever noticed how similar these drivetrains are? I was really studying the little Cub and came across this John Deere. I had to admit that I was shocked to see how closely they are the same. It is almost as if they were built by the same dude. I do know the first was built by Dan Hoefler, but I wouldn't be too surprised if he helped on the 110 also. Now with that said, does anyone know of any build threads on either of these two. I kinda would like to know how those track links were made and much of the drivetrain. Any help would be much appreciated.

Here is a thread on Dan Hoefler's 100.

A LOT of work went into that machine!

I can't believe he only had 9 months into the project. The track setup on the John Deere crawler looks to be identical. If Dan didn't build those himself then some of his tooling and plans had to of been used. Either way their both awesome pieces. Going by what is listed for the track links most of the items were custom made also. I could only dream of doing a custom crawler at some point.

I do like both. I am honestly thinking of doing one very similar to these two out of a 140. I do first, off topic here, have to finish a hay wagon, then a sprayer, and lastly a restoration/repower of a 73 140. Then, I will get started on this, but I have started planning now. I really wish I could find more info on these. Even an email to whoever built these would be useful.

Does anyone have any guesses how those drop boxes work that drive the tracks? Is there gearing in there that makes the track go forward or backward? Or is it just a fancy brake setup?

Well, I now have an idea how to bend the links. Use a shop press and a metal brake. I might have to custom make the brake to bend them in one shot. As far as those drop boxes, still have no clue how to do that. I might just go with two hydraulic motors and some bi-directional levers.

Can anyone supply me with pictures of the driveline of a Struck and Lennox? I see there is a belt drive setup on the Lennox, but from the one photo, I can't tell how it works. Please help.

Here is a photo album of a crawler that was made from a 140.

That thing is truly awesome! I wish I had the time and equipment to make something like that.. Was there a how to or anything to go along with the photos?

There are manuals for two Struck models in the downloads section.

Also, I've got a build thread in the Ford / Jacobsen section

From what I can see, both the Lennox and Struck crawlers use a little sprocket driving a larger sprocket firmly mounted to the rear track sprocket as a final drive drop.  The Lennox and Struck are open chains. The Struck is a #80 roller chain.

 

Using a chain case as the conversions appear to will extend the service life of the chain but raise the issue of keeping the lubricant where it belongs and not dribbling out making an unholy mess.

 

Unless I am drastically mistaken, full size crawlers use a pinion bull gear arrangement to keep the torques a bit lower on the drive chain.  Some go as far as using planetaries inside the rear sprocket for similar reasons.

 

Even if you use individual motors to drive each track, you may still need a drop box to keep the motors high to improve ground clearance.

 

IMHO, chains are easier for amateurs to use as they will tolerate differences in center distance and alignment better than gear sets.  Chain drives also use readily available components like sprockets, hubs, roller chain available by the 10' box.
