Snow Trac two band ice scrapers

[300 H and H]

ST4B's had an optional ice scrapper that was never offered on an ST4....And they work well enough!


My machine had them when I bought it. Another member here requested phots of mine, and how they are mounted. I thought maybe other would like to see how they are made and attached. they really seem to work well, as I checked, but never had to clear my sprockets of ice. The clearance at the tip of the scraper is only about 1/8". I have to credit Joe Smolar (He restored this machine some years back) for this modification, although he may have had some help, maybe by our illustrious member Lyndon....

I hope others here will find this a usefull addition, if your having problems.

Best regards, Kirk

What about big wheel ST4s?

What about big wheel ST4s?

Just my opinon

The Ice Scrapper is ONLY for the Snow tracs with Two 2 band rubber Track (with big wheel or with the set of the boogie wheels)

The Snowtracs with Three 3 band rubber Track had deferend type of Sprocket, and they dont need the Ice Scrapper.

UNLESS you have a frankencat with two band, bigwheel. Then you need the scraper, but good luck mounting it. I've seen a couple one conversion and one of the MacLarty assembled ones.

Nope, our 1958 two track ,big wheel Frankencat moved to Montana

Would the two band work better if you removed the rubber covered center piece and made them an open cage like the 3 band or would the ice still build up on the brake drum?

Found this thread last year after having a close call with ice buildup, so thx to 300 H&H and JmVT for the info. Needed to do SOMETHING.
Machine looks to have had something installed on left side only (the orange bracket), maybe it was for a scraper long gone. I don't trust my welding enough to place steel angle iron anywhere near the cogs, so used leftover plastic from sprocket project .


Also tried the playing card in bicycle spokes idea to scrape track underside before snow got to idler or sprocket.


good luck to 3512b...

I'd leave the steel ring in place to reinforce the mounting ears...
