I don’t know about the R’s or T’s but a full day on the 11N I used to take care of was work! Loud, dusty and until right before I left no climate control. No fingertip controls lol. I thought it was bada$$ to run it for about two hours. It’s certainly a different feel compared to the smaller machines. With a blade full the only way you’re going to influence direction is with tilt. If the ground is marginal and it slips a track a little you’re stuck.
Jeff,
You sized up 11s okay and DESERVE THUMBS UP
for doing the maint-mechanic work on the 11N...operating is the easy part.
1st 11Ns I was around mid-80s, 3508 engine life a bit over 2000hrs ditto 3508s used in Demag face shovels. Same deal with the 1st 84W-D10s; after 3 weeks hard nose flipped engine out and trans out, teething new model problems. Dealer mechanics changing track hot-links 2-3 times per week with Cat's C-frame press all over the US. We had to remove track assemblies to move D10-11s until the mid-80s to make legal weight. It is annoying when a youngster mechanic is advising, 'how to track' a large dozer, i.e. he does not know what he is talking about, LOL
Another D575A video shot by John Mitzel (contractor-equip owner) of his competitors new toy @ El Sombrante landfill S. Corona, Calif. John likes to hang out @ Sportsman Bar crying in his beer over lack of work. Sportsman is older than me (72), watering hole for local miners, truck drivers and generally societies' entertaining bunch of f-a-$luts.

Comparison size D575A to D11s
