So what gear do you think those 57s are loading in,bet it,s not 3rd.We couldn't load in 3rd even if we wanted to,our material is alot harder to load up than what their in.Cat scraper,s started getting rougher to operate when the Es arrived,but i will stay on my E,the Gs are overpowered and lighter than an E by Abit especially the 57s.Spend 6 months or more on them,then you would REALLY know.
Video 57s are all powered with C18-C15s that electronically reduce power in torque converter 1-2 used for loading as designed by Cat. I've operated 57s part time since early 60s, no suspension seat, ROPS, cushion hitch, pilot operated hydraulics...If the material is fluff no problem to load in a higher gear.
If you want pain try a Cushion Dozer; well Aussies don't use them as you're aware/
I had customer request for 5,000lb add on weight to help eliminate 'out of cut' wheel spin on re-powered 51s; better solution was using the ECM.
C18-C15 combo reduced fuel burn, decreases cost per hour to operate the scrapers...reducing the overhanging weight on the cushion hitch increases service life to pin-bearing replacement, i.e. reduces cost per hour to operate.
Thanks for sharing you're operator seat knowledge and yes scrapers are not pleasurable to operate but improving!
