Pictures of Cat 830MB and Clark 290M

I just bought a Cat 830MB and would like to see pictures of them and Clark 290M's. I'm curious what the differences are between the two. Thanks!

How do the quad-trac tractors perform against pneumatic-tired tractors on pans?

Just wondering how much more or less traction the quad tracs have in front of those pans as opposed to rubber-tired?

the biggest advantage with the track type is the low ground pressure, better traction and flotation in soft/muddy conditions. the disadvantages is the cost and maintenance of the undercarraige. i have herd that the Case (cant afford something else) Quadra trac have many drivetrain problems

the advantages to a rubber tire is the cost
disadvantage punctures, less traction in wet/muddy conditions.

i had that 9420 for 3000 hrs and i could go pretty good in wet conditions but the bowl would get hung up.

I thing the best combination would be a JD 9520 with duals and an Eject pan with tracks. it isnt the tractor that gets stuck its the bowl that gets the tractor stuck....

heres a few pics

They are very good for short hauls, wet and or steep hauls. They're disatvantage is when the hauls start to get longer, keep in mind tracking around wears the undercarriage quite a bit. This is why McAninch also has a whole fleet of ADT's and excavators. :usa

as far as the wear if a dozer is stripping topsoil all day or grading pads or running around pulling a pan all day as long as you have the tracks checked regularly to get the pins/bushings turned the wear is not that significant. i dont think McAninch would be using D9-D11's if they werent getting good wear out of the tracks....

Good point, I guess I didn't think that one through very well:Banghead :beatsme Long day I suppose:pointhead Besides the first scrapers were ALL pulled by track type machines. Don't get me wrong, I admire just how well McAninch moves dirt and how efficient their pans are, but I'm pretty sure they are designed to excel at short hauls and steep terrain.

it was a tunnel fire. the old tunnels had both wood and concrete in them. befor they had spray on concrete they would use a post and beam kind of thing then put wood behind it to keep the rock from falling and breaking it. some kids got in the tunnel and lit the wood on fire so we went in while it was burning and broke the walls and roof down to put the fire out. it was a bit scary at first, driving into a pitch black tunnel with nothing but you head lights on and then they tell you to tear the roof down. we worked 24 hours on and about 12-18 off for 3 weeks and only broke 1 hyd hose and 1 window.
