Ah,them old school dozers are great,the hi-tracks don't do much for me,notice that the FD50 is not too much smaller by any means,neat to see some still working
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
track noise is called big tracks, long links in rails coming in contact with idlers and sprocket. camera doesnt do justice to d11 because fiat allis is just as big.
My late uncle was a top mechanic in heavy equipment. I asked him once why Cat was so much more money, new or used either one. He simply stated it was because they are worth it.
Remember, looks can be decieving. Perhaps it appears more track slip goes on because more track is shown to the naked eye with it going around the sprocket which is much more visible on a high track than a conventional. I would ask the question of you if it was such a huge problem why does the more expensive (and lets talk D11/D475 class machines here) high drive machien sell 3 units for every 1 of the low drive machines worldwide?
Somebody tell me, Is the track on the drive sprockets on the D11R making 'music', seems to be chiming away there like something is slightly mis-aligned ??
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?
The ground beneath the tracks isn't always consistent and he may have had a bunch of big rocks when you saw him slip, I also noticed the D11 filled his blade sooner and was also pushing more material at the time.
I get "dozer leg" just watching that. I have a nasty habit of jamming my left leg into the consol when she starts to push hard. I have to force myself relax. Our old tiger didn't have cruise control and I would try to mash the pedal through the floor. .
What you see in slippage is actually just the operator digging in a little too far and the Cat losing traction for a moment. This is actually a pretty normal for fully loaded dozers working in areas like 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.
from what I see here, there isn't that big a difference in the ability of the two... How old is the Allis? seems to run pretty nicely... it's probably paid for too
@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.
I know I am daft simply because on first view, I thought the heading to this said "Cat working with Flat Allis.! That it was some kind of Rock Duo. Thanks for the commentary, makes all the difference to understanding of the vid. For an "old Dozer" the Fiat Allis is not shy on those slopes or of the work! Take care. mrbluenun
Southern Mechanic I'm old enough to remember when they first came out...They had good marketing but, I remember too, that there were some grumbles...I just did a more recent check and it seems that there are advantages with either...It's all about personal choices...:)...My favorite Dozer D11 is most often a High drive and they are BEAST...But the Komatsu 375 is a low drive and It's a BEAST too...Oh well..Losing mud in the open space in the high drive seems to be the favorite reason...:)
attilla2012 How many passes did you see each Dozer make? When you saw that D11 have some track slippage who knows what was under his tracks. I don't care which Dozer you are in you are going to get some track slippage now and again if you got a full blade. If you compare how many yards a day that both machines push I have no doubt that the D11 will beat the FD50 hands down and uses less fuel thanks to better engine management. I have a soft spot in my heart for FD 40\50 the biggest problem with running one anymore is you almost need one or two clapped out ones for parts anymore. I will have to admit it did like seeing a FD50 that looked in that good of condition still working hard.
Old 9H I used to run would move more dirt than them fine fiats . We used to take a 11 on one side and a 11 one the other side of a 50 and take him over the hill with us. Him (Steve) screaming on the CB radio you can'nt do this to me all the way over the edge with his tracks going backwards. Those Fiats had nice wide spot on back of blade to do that,I think they made them that way because they were always stuck. I'm glad I run the 11's
PAmining The math the engineers working for the the two main companies I work for all agree anything over 300ft and your better off to load and haul. Anything 200-300 your barely breaking even. No matter the size big or small. But hey if this is working for you guys then far out. I always say there arent many absolutes in the excavation business.
MrBiggreedy Very true for production stripping. In the case here, the tractors are sloping the final reclamation of a backfilled pit. This kind of work can not be done by loading and hauling. This is what bulldozers are designed for.
They are likely backfilling part of the mining cut so they will need to bring up the sides of the cut as they go. Also ,the high sprocket won't wear as fast.
I said the same thing when I first saw an FD50. It's deceiving once you get inside the cab. Also keep in mind the dozer operator's eye is off to the sides watching the blade, not directly out front
PAmining Exactly right! You don't look out over the hood while working very much at all.Hell the cats of that style only have about a one foot wide window directly in front . You look out the door windows when working. Good video as usual . I like all your videos
Cat makes good stuff, but my money has always been on other manufacturers for brute power. A few years ago we tied a brand new D6 and a brand new Deere 850 together by a cable and the Deere dragged that Cat all over the place... wasnt even a contest. Hooked the same Deere to a D65 Komatsu and it was much closer, but the Deere nudged the Komatsu a few feet. Saw a video on youtube of a D8 with a single shank ripper next to a same sized komatsu with a multi shank ripper and that Komatsu pulled.
How does the operator of the Fiat-Allis see past those massive air intakes and the side by side exhaust stacks? At least the CAT has lower profile air cleaners and the stacks are spread apart so the operator can see between/around them. Design mistake Fiat-Allis?
Hi Mack, that's not where you look when your pushing material. The Fiat Allis has little windows on the lower sides of the cab. The Cat operator is looking through his doors . That's where you look to see the side of your blade where it contacts the ground.That tells you where your blade is. You can't see the ground when you look straight ahead. The first thing you see if you look straight ahead is hundreds of feet away.You can't see your work looking over the hood and the blade. Now go find someone to teach you how to run one and you will never be the same. Power is addictive!
Ah,them old school dozers are great,the hi-tracks don't do much for me,notice that the FD50 is not too much smaller by any means,neat to see some still working
Love the old FD-50 by the way. That old dude looks like it has paid for itself a few times over.
IMO some of these older dozers that are still working should be great for some newbie operators to jump in and learn how to operate
Are some those vids near Brockway Pa? There was a D11 off Rt 219 between Brockport and Ridgeway. It was quite a dig.

I love the way those single shank rippers set off the D11's..
Thanks for re-loading this video Justin
CAT's largest dozer and a rare old Fiat Allis make quite a team!

Another awesome video. I just recently just ran a D11N pushcatting 657s at my job.
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?
I don't give out the location of any of the mines my videos are filmed at, but this is an anthracite coal mine.
The noise level inside the Fiat is higher than inside the D11 because it's an older machine and not insulated like the Cat.
The ground beneath the tracks isn't always consistent and he may have had a bunch of big rocks when you saw him slip, I also noticed the D11 filled his blade sooner and was also pushing more material at the time.

I thought the I thought that ACs largest dozer was their massive 41.
@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.
I wonder if the FD50 might have been repowered at one time.
saying a 850 hp d11 can out push a 550 hp fd50 welll u dont say i say the fd does awesome for what its got
Big machine D11 is caught. The powerful body is beautiful. Thank you from Japan.
70 Ton FD50 can still push. Not far behind the 100 Ton Cat D11.
from what I see here, there isn't that big a difference in the ability of the two... How old is the Allis? seems to run pretty nicely... it's probably paid for too
is the Fiat Cummins powered nice video have a good day
The blade on that Fiat looks almost the same size as the one on the D11.
@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.
I know I am daft simply because on first view, I thought the heading to this said "Cat working with Flat Allis.! That it was some kind of Rock Duo.
Thanks for the commentary, makes all the difference to understanding of the vid.
For an "old Dozer" the Fiat Allis is not shy on those slopes or of the work!
Take care.
mrbluenun
I would really like to work such an amazing machine!! very nice video, greetings from GREECE!! D11 rules.
I love watching the big Iron working
+Scott Lundy Mining is the way to go if you like big iron!
wow havent seen a Fiat-Allis for a long time great vid!
I would rather have the Allis myself.
Awesome video!
Never did understand why cat never had a support roller for the track on the r models. Lotta tension on the drive and idler
Thanks! It did. Hard rock wears the tracks down
The FD50 is about comparable in size to the old Komatsu 455 (The Komatsu had a bit more power though)
I was gonna say I never run anything bigger than a D8, but I rarely look out the front window... mainly to the left behind the blade and the corners.
Thank you! Most operators I talk to are like that, and like to be left alone to do their job.
Thanks, glad you enjoyed it! The two dozers to make a good team!
Where in PA is this mine ?? Also what r they mining ??
How is the noise level i the cabins and do they have same age?
where are these dozers located? coal mine in pa?
Yes, this a a surface coal mine in PA
Look at how tall the grousers are on the Cat. All the ones I've been around are much more worn.How #&%@*
those Hi drive D11's are so noisy...That Fiat sounded nicer...I heard the regular track drive is stronger and better than a hi drive.
godbluffvdgg the high drive was designed to reduce shock load to the final drive and keep the final drive out of all the mud and crap
Southern Mechanic I'm old enough to remember when they first came out...They had good marketing but, I remember too, that there were some grumbles...I just did a more recent check and it seems that there are advantages with either...It's all about personal choices...:)...My favorite Dozer D11 is most often a High drive and they are BEAST...But the Komatsu 375 is a low drive and It's a BEAST too...Oh well..Losing mud in the open space in the high drive seems to be the favorite reason...:)
Awesome video.. That D11 looks like it recently had a track replacement
Its all about Build Quality and Parts availability !!!

i like the allis! not if i had to drive it all day though.lol
Thanks! Thats cool.
Good looking old dozers. Why not haul the material down there instead of pushing it as thats a long way to push?
Moving dirt with dozers is always cheaper then loading and hauling

10-4 . Didnt catch they where finishing in the video. That explains a bunch.
They are likely backfilling part of the mining cut so they will need to bring up the sides of the cut as they go. Also ,the high sprocket won't wear as fast.
Well I'm sure they kept you entertained! haha
I ran D11s and the other ! The cat will work cycles around it

An 850 Deere is bigger than the 6.
BOTH!! GOOD DOZERS!! but the nod always goes to CAT POWER!!
that old fiat is a tough sonnamabeech
Standard blade like this is 9'3"
Thanks man!
man....the camera doesn't do this massive D11 any justice
FD 50 very rare!
Nice video: thanks for the opportunity to view it.
Thanks

You never look out the windshield, you watch the outside corners of your blade through the doors
That she is
whats the height on that blade of the d11?
Fiat allis fd 50🤟🤟🤜🤜🤜
That Fiat will never be a good as a cat
@PAmining Good thing you don't do that.. *S*
89'
Man that would make for a long boring day if you ask me, same thing, over and over.
go cat!!!!!!!!!!!!!!!!!!
I bet they flip coin to drive the cat .
