Dyno pics, and no I don't mean the prehistoric type!!!!!!!!1
Here is a pic of the gauge that reads the HP output on the dyno.
This one reads RPM
And this is what it looks like hooked to the crawler.

There really is not much in a modern crawler in this size range. The Nortrac/Northern Tool/Bob's Crawler Company is not too good of a machine. About the only thing in the 420 size range that I know of are the SAME crawlers out of Europe.
They have tried other types of machine, and for what they are doing, the 420 is the best machine for the job.

Hi,
It's rather annoying to me that Deere has never made a 420 sized crawler in all these years since the end of the 1010 line. I can see where the market could well have dried up come the end of the 1010, but that was so long ago that most of the old iron is pretty well worn out.
I'd absolutely love to wander into my local Deere dealer and buy a crawler/dozer based on the 4000 series (say the 4720). I have a 4500 wheel tractor/loader and love it to death. I'd get a 4720 crawler in a hearbeat to then retire my dad's poor old 420c to going to shows and such.
But, no. I can't have one because none exists. Dang it.
I can't be the only one who wants one, either.
And, no, one of those Bobcat style skid steer units with the fake tracks on it holds no interest for me at all. I want a *real* crawler made from lots of steel parts.
So, as it is I'm looking at a complete overhaul of the 420c to make it go several more decades, or buying a JD350 used and then probably having to overhaul that as well (at least parts are easier to come by). Sigh.
I wonder if I could go buy a new 4720 and then make a crawler out of my 4500? Now, *there* would be an ambitious project!
Later!

Stan makes a great point. When you think of the beginnings of Lindeman, it was all based on need and adaptation of existing tractors. I wonder if there would be a market for a new small crawler based on either the 4000 or 90 series compact tractors. It would give you the Deere/Berco parts systems for support and name recognition and that whole "Built in America" angle.
It would be a cool project to take on. Who knows; in the end Deere may end up buying out the product and you've created a new legacy on an old idea.
I've got to take a look at my 790 when I get home and see how much work it would take to adapt a different final drive to make it a crawler. It would be a pretty slick orchard or small ag crawler if you could pull it off.

I don't want to rub anyone the wrong way or anything but I know deere and yanmar collaborate on many machines. I remembered seeing this one and thought you might be interested. Rubber tracks, and I don't know what they offer in the way of blades. I don't know if it would be as heavy duty or not.

Hi,
The Yanmar is interesting. At least they have rollers on the bottom to carry some load unlike many other things I've seen.
My ususal beef about rubber tracks is not that they're made from rubber, it that they tend to be wrapped around wheels without any rollers. So, the load is carried just like the wheel tractor they are derived from. Not much good to make a dozer out of from my POV.
Something I don't like about tractor-derived crawlers is that they tend not to employ steering clutches. They rely on differential braking of one side or the other, splitting the power.
I had a Terratrac GT25 at one point, and while it had steel tracks, it steered using differential braking. It stunk compared to the 420c, for many reasons, but it really was bad because it had this nasty habit of speeding up in a turn, where it tried to whip-end the operator off of the thing.
From the Yanmar website, they're not exactly steering with brakes, but by operating the differential such that it slows one side and speeds up the other. I can't help but think that the end effect would be the same as that old Terratrac - trying to toss me into the weeds in a turn.
Besides, no steering levers? I'd feel....lost.
I also see nothing about dozer attachments, either. I note that the track frame is pretty short, kinda looks like a 420c 3-roller to me, so perhaps a dozer is a bad idea on one. That would make the thing useless to me.
I'll have to eyeball the SAME offerings. I recall way back in the late 1970's when we had SAME alongside Deere at our dealership, and my impression (which is really from my dad and uncles, since I've never had one myself) of the brand is that they weren't worth the powder to blow them up.....
Anyway, perhaps I ought to modify my lament. I want a 4720 tractor on a 440/1010 5-roller sized track frame, with a PAT blade option.
Toss in wet steering clutches and I'll sign up tomorrow!
Later!

Hi,
I just got off the SAME website, and it looks like the smallest one is 70 HP, which puts it into the JD450 class. I'd like something smaller, or at worst no bigger.
So I'll keep on looking at used JD350 and JD450 machines. I'm not holding my breath that there will be a new small crawler from Deere any time soon, although I do have a fat enough line-of-credit with Deere to buy one should it ever happen.

What a hoot. The Struck crawlers are actually out of Cedarburg, WI (I live in the Township of Cedarburg) and I'd never heard of them. Here's a link to their models. It's more of a calfdozer sort of setup but interesting.

Had a Struck about 25 - 30 years ago, complete with 8 hp Techumsi (sp). It used v belts for drive and steering. Push the lever one way for forward and pull the other way for reverse on either side.
