Somerville, Indiana | A 6R will do much more work in a week than a 6N will...After using both, you will park the 6N if you are looking for production...Look at the blade first, on the 6N it is only 30 inches tall, and ends are open for the 6 way blade to do its thing...6R blade is 4 feet tall, semi U blade with the ends curved forward and closed...No comparison whatsoever...We have had both here the last two years...In 2010 the 6N stayed for 4 hours, it was provided by Cat to make up for having to back order the correct rails for our 6D...So, as a by the way sort of thing, bolts holes are different in the rails of D6Ds consistant with whichever grade of rail is ordered...Have changed rails at least 10 times here, never ran into a bolt pattern problem before this fall...Previous owner of the 6D had Berco rails installed before he sold it...When we went to Cat rails the first pair came in with wrong bolt pattern, second pair came in a link too short, third pair fit...Took from Tuesday to Monday to get the rails right...Normally a next day thing as we ask to work in our rails when the track shop is between jobs so we get them back the next day.
Shouldn't have went off topic, jus sayin what our experience was and getting it the expensive way around...For light work the 4H to 6N and 6K series will grade just fine...For all around work to make money, they are harder to put on ajob here.
