  • Interesting comparison because it looks as though the old Allis is outworking the D11. Also, anyone else notice on this and other videos that conventional tracks don't seem to slip as much as Hi drive. Don't know why this should be. Any experienced drivers notice this?

  • @attilla2012  There's a reason why big dozers don't have real wide pads. This isn't a little D5 with LGP, this is a mining dozer. The D11 can out push an old FD50 any day.

  • You throw up some awfully cool vids bro...keep it up! I subbed..

  • Thanks man!

  • How is the noise level i the cabins and do they have same age?

  • The noise level inside the Fiat is higher than inside the D11 because it's an older machine and not insulated like the Cat.

  • put the fd 50 up against a D10 and it will be more fair. Personally I would prefer the HD41 but thats just me , I like older equipment better. but I hear ya about the parts availability of the FD. and further more wider pads will give you more traction but PAmining is right these are mining/pit cats and the narrow pads take a ton of stress off of the under caraige and that is very important in these harsh conditions

  • @kennethrobinson11231 You must have rocks in your head!

  • Wider track shoes will not reduce slippage, and the D11 will bury the Fiat when you actually measure what is pushed at the end of the day. Also lets not even begin to discuss availability... FA looses every time!

  • @attilla2012 Yes the high track seem to have more slippage,they should have designed this machine with wider pads.I wonder which one uses more Fuel and how much more per day? Bigger is not always better.

  • Nice video and thanks for posting it, looking forward to more videos.
