Hi Guys: I was reading the other day in my Allis Industrial Book that the little H-3', H-4's and 652 and 653 were used in Vietnam.  How reliable are  these models? Also noticed that the H-3's set a record in Nebraska for pulling 107 to 108 % of its weight .. thats a pretty great torque rise for a small dozer. Anybody know about these machines? Thanks! Orangeman

Do you know the Nebraska test numbers on those pulls? Interesting.

My gramps had the first ever tractor in Nebraska to pull its own weight - an Oliver OC-15.

My gramps Howard van Driest was Experimental Engineer at Cletrac and Oliver Corporation. After the plant closed, he and my uncle started an excavating business, initially using Cletrac and Oliver Crawler tractors.

I've got an HD4 dozer with a 6-way blade.  What do you want to know about it?

Hi John:

Some questions I have are:

How reliable are they? Any particular weak points that you have observed besides the normal wear on the u/c.  Also, given there horsepower to they have sufficient push as compared to a International or a Cat?  Thanks John. They look like good machines but have never had the chance to operate one.  Would really enjoy hearing your thoughts also on its ease of operation?  Thanks! Orangeman

Blake:

The Nebraska Test for the HD-3 Allis was # 794 hope that helps ... wish I could have answered your question sooner. Orangeman!

I had a model 655 with loader bucket and detachable backhoe. Sure would dig well with the bucket. Handled the backhoe unit pretty well too. A couple of things I didn't like. They started with a radiator and built a tractor around it. If you ever have to repair the radiator you'll know what I mean. Adjusting the the steering brakes was easy. Looked like replacing them would be a major operation. Mine was a tough little machine and I got alot of work out of it even though it was on its last legs.
