Cat HT4 Questions

My HT4 parts catalog show a bulldozer blade that attached to the loader arms, but it also shows an angledozer attachment that attached at the points you show in your photo, and was raised lowered by linkage to the loader, if I'm interpreting the parts diagram correctly. That could explain the mount in your photo. My buddy has an HT4 and the track frames are bare on the outside so it could very well have supported a Cat 4A/S mounting arrangement too, possibly a tool bar arrangement as well.

It would have a rigid frame though, not very good for a dozer setup.

This would be a better tractor.

Agreed, I doubt Trackson sold many of them, just not the right tool for the job compared with a purpose-built bulldozer

I picture 3 you can see a clevis welded on the under side of the loader arm as well as bars on the U frame . I am guessing the bars are pined to the arms to lift the dozer blade.

Not that familiar with the 7u and the HT4. Guessing since the same base unit the track frames could be traded back and forth . Probably even the track frames for the heavier undercarriage would bolt on. If they did that in the same time period as the 7u.

@Rome K/G - Ya, i'm watching a few including the one you sent me...I wasn't sure if for scap value this one was worth saving for some of the options mentioned (dual circuit hydraulics, 5 roller track frames and a decent looking undercarriage).

@neil - As always, you are a wealth of information. I agree, it's probably was not the best tool for job...just wondering for the money if it's worth saving for any purpose other than parts. I hate seeing old yellow iron go to the torch.

Thanks to everyone else for the feedback

I'll put out an update once I go see it.
