What is a Cat D7E Worth

What's the serial number? It's probably 47AXXXX. That is a 180 hp tractor known as a high horsepower version, starting with serial # 47A3396. The older ones were 160 hp tractors. All of them were built tough and had a good reputation for reliability. Did you or someone else measure the undercarriage? I have found that most sellers either fudge their estimate or don't know how to measure it. The UC is typically your most expensive item to replace on a dozer. It's worth spending the time to measure it.

The Direct Drive version wasn't built in the volume of the Power Shifts, but they are still very popular in South Texas root plow country where all the brush has a sticker on it. They will stand up to the constant pull and heat generated by the root plow.

I see them advertised for $20 - 30 K with the equipment traders around the state with PS and hydraulics, but I wouldn't give that. I think I could find a good one for around $12 -15 K (or even less since it's cable) that would last for years. I know you can find them cheaper in the midwest but you're going to have some freight that adds up quickly.

Anyway, that's my opinion. I've got a PS version with hydraulics and they're a good tractor powered by a D339 4 cylinder with low RPMs and lots of lugging power. I think that's why they last so long. Don't get em hot or they'll crack a head and that's expensive, $4000 for two new aftermarket bare ones, and I couldn't find used ones. I haven't found anything else on it that wasn't readily available either new or used.

Sounds like it fits that 9' root plow you've got. Good luck...

The serial number is 47A4200. If I knew how to attach pictures I would do so. Do you know how this is done?

Make a new post in detailed mode (not quick post). Scroll down the page and look for "Manage Attachments". Find the pictures on your computer and submit them with the post.

They are a little off on the date....47A4200 is a 1967 machine...production ended in 1970.
The 180 hp version came in at sr. # 3678

Good machine...I would prefer the direct drive myself.

A D7 would be rather small for doing much root plowing. The tractors I saw with root plows were mainly D8s, and every now and then a D9. During the late 70's and early 80's a lot of the brush country between McCook and Rio Grande City got cleared and made into 'farmland'. After a couple of good years, when the climate returned to 'normal' (read dry), you would sink to your knees in the dust, and the wind would blow sand drifts across the highways.
Years ago the AC dealer at Edinburg would always have a couple of HD-21's around, and there was a place just NW of McAllen, on the 5 mile line, that I was told had a contract to clear brush on the King Ranch, and he had 8 or 9 D8Ks.
Back in the 80's, everybody and his brother had an used equipment yard, and most of the machines were being exported to Mexico. Before Holt at Weslaco cleaned up their back 40, they had lots of derelict parts tractors. Othal Brand, and Valley Onion had D8s and root plows to break up the caliche hard pan. Krenmuller Farms and others had smaller Cats used for deep tillage.
I have a newspaper clipping for a field demonstration of a D6SA, that had rubber tracks for highway travel between farms.
