    I drove one of those when I worked for a construction company in the mid eighties. It had a spring loaded blade for pushing Catapillar pans. It was a monster. Plenty of power.

    Around 1970 our Ag class toured Central Ohio Coal where they had 5 of those with 20' blades pushing side by side doing reclaiming.

    I watched one of those push in the early 1970s at an asbestos mine in northern British Columbia at Cassiar when it still was the biggest dozer in the world.

      Interesting thing is the narrow blade and bracket, must be a custom usage

    I ran into one sitting high on a side of a gravel pit. I felt it's primitive retired historic soul reminiscing a long enslavement to moving massive amounts of rock n earth. A Wisconsin west Alice manufactured icon! Who's historic build up then swamped in a bogg of economic conglomerate congestion. So memories still rekindle via standing relics

    When I was a kid here in Nebraska my Uncle run one of them when they built the power plant. They used it to push big scrapers. I can't remember what kind they were but the big green machines.

    Agree with that blade setup ole Roy pushed scapers or pullers the type that needed a dozer to help them scrape up a load. What the thicker plate in the centre of the blade is for. Also no tilt hydraulic cylinders and I would put him in a D10-11 Caterpillar size

    • @ricknone4686

      The Fiatallis HD41, 41B or FD50 were in the Cat D10 class as dozers, much bigger than a D9.

    I vaguely recall 2 of these machines working on Fraser Island (Kgari) off the coast of Qld ,Australia in a mineral sand mining operation during the late 70's, early 80's. Used a much larger blade and wider tracks.
    Great to see a surviving example .

    That is not an original HD 41 blade. It's like a modified HD 21 blade. The HD 41 blade would be about 1/3 larger and would be angled on the left and right side.

    • @RJ1999x
      @RJ1999x 2 місяці тому +2

      @09amusement no, not really, the early tractors didn't sell, they were too expensive, and too big. The model U was built under contract, but the co-op went broke, so Allis Chalmers was stuck with the tractor, and decided to sell the remaining stock, and get out of the tractor business. They hired a guy (Harry Merritt )to dispose of these, and flying to California he saw the orange colored poppy fields and decided the tractors should be painted Persian orange. That fueled sales, and kept Allis Chalmers building tractors, so the U was actually the tractor that put them on the map

      Well, they're old pieces of iron. But every operator that used these old Fiatallis monsters always said that they would outpush and outrip a Cat any day. Many of these were still around and working in recent years.

    Love the big dozers, too bad more of them aren't kept instead of scrapping them. There was a quarry operation in Festus Mo that had a pair of HD-35 s and a 41. He was selling stone and leveling the bluff alongside the River ,to sell for strip malls. He would buy these big units from, I believe , government surplus sales. Use them till they needed heavy repairs then let them sit. A few years back when the scrap was super high, away they went. The average collector don't have a chance due to the high cost to buy , repair or transport! The only versions of those giants I ever saw in person, they sat there for years, now scrapped on site!

    • @livingbeing1113
      @livingbeing1113 Рік тому +1

      Very unfortunate. These monsters deserve a good retirement, being restored and sitting somewhere after they finish their gruelling job, maybe in a collector's property. But like you said they can be expensive, not only for the restoration but for the transport too.
