Mitsubishi on real boggy ground in NZ.

[dozeron]

Hi All,
Yes I agree, the tandem wheels would/could have a negative effect on the axles/bearings etc. It may well have been a short term arrangement just for this particular contract, not really to sure. I have seen first hand the problems associated with fitting 2 or 3 extra wheels to farm tractors for working boggy or soft ground, causes lots of problems!!

That´s done very often in Sweden. Sometimes even on the front wheels.
Could it be that modern tractors are better suited for dual wheels?

I didn´t know that.

This grader among other big (and small) graders were also discussed here:

I´m sorry, that thread is in Swedish but at least there are some pictures. And Nick knows enough Swedish to translate.
And of course there are other Swedish members that can translate among us.

Robban!

There are even pretty common use of triple! (Three wheels) here in Sweden on fram tractors then they comes up in size.

Hi dozeron, Where did you see that Mitsi with the duals, looks awfully like one that I saw at Papamoa near Tauranga, and was owned by Murray Salt from Tepuke, I think the duals were put on to give it more floation in the loose fluffy sand they were working in at the time.

Hi, Nick Drew.
Sorry M8, but Cat hi-sprocket drives pre-date the Acco dozer by about 5 years. The first D10's, the 76X's came out in 1978 and were the first of the Caterpillar hi-sprocket drives. There were several others before that, the Cletrac model F in 1919, the Best Humpback 30 in 1916, and a Holt tracked ditcher in 1910 that had the drive sprocket where the top carrier roller would situated on say, a Cat D4, pre-hi-sprocket drive. There was also a U.S.-made agricultural crawler, the name of which I can't remember at the moment, in about 1931. I seem to remember that there is one of these jiggers in the Hiedrick Ag Museum in Woodland, Ca..

For what it's worth, I have been told that the big grader diid do a couple of beach reclamations jobs in Italy at various times. As I understand it, the reason that these machines never went to Libya to the contracts that Acco had for them was the trade embargo that was slapped on Libya after the Lockerbie plane bombing in 1983 when Libya refused to release the suspects.

Just my 0.02.
