Went and checked on a customer the other day that we were demoing a new D6T too. Evidently the new J series JD dozers have went to hydraulic winches and they have lost thier winching capacity by about 20k lbs. pressure reliefs come on at 90k. so that puts CAT in a good spot for roust about work with our optional mechanical winch. anyway this customer has about 10 850 JD dozers so we let them demo it for a month. So i show up unannounced on the well site and low and behold that have the dozers nose to nose for a full pledge push off competition. This isnt something i recommend people doing but they were already starting so i didnt interupt. when the black smoke rolled all i could think was of how fast that hydrostatic 850s track spin when she was being pushed backwards lol. of course it wasnt realy fair because the system one grousers are much taller than that JD standard grousers and the CAT has a a few pounds on an 850, but it was interesting to see
Sounds like operator error to me or the guy on the cat was cheating...Lol
The Deere just didn't wanna make the Cat feel bad. You know tryin to build up its confidence.
be careful here. Just on a demo where the opposite happened...850J WT (30" Pads) with winch. The relief pressures were set properly on the winch so that it matched the performance of the mechanical winch....and the 850 actually pushed the D6T backwards with same pads (system one 30"). Again, the weight was equal due to the front weight placed under the hard nose on the 850J to counterbalance the weight of the winch....matching the weight of the Cat. So sometimes there are contributing factors such as poor setup from the dealership (not setting the relief pressures or not placing counterweights underneath the hardnose) for the winch or operator error...or machines not matching specifications. Just my two cents worth
Definately, the machine setup can make or break a machine. We have 2 973's on site right now. Both are replacements for our normal machines, but oddly enough they are brother and sister. Vern's is serial number 3124 and I'm 3125. They have relatively the same hours, exact same configuration yet oddly enough... mine is a pile of garbage. 2 machines identical, and yet they are worlds apart for performance. Today I picked up a 72" slabtop for a sewer manhole. I would imagine its probably a good 2 1/2-3ton chunk of concrete. I went down the ramp with it hanging on the sling from one of my corner teeth and as soon as I went down the ramp she started pullin me over, had I not dropped it I would have been upside down in a 12ft deep hole. Vern hooked onto it.... no problems whatsoever going down in the hole.
haha
Irrespective of performance, power etc, surely both machines must weigh the same :beatsme Did he pick it up from near exact position you dropped it from, did he use same position on bucket? You were moving when it got to the point you felt, enough! He was obviously stationary when he picked it up again. Was it possible that being slightly further down the ramp would have altered the balance point ? Did you see him pick it up again, was he ass first down the ramp? What would you do different next time? In my book it goes down as a near miss! Log and report it and everybody learns from it. Sorry, that gets away from your point of differences in same machines, which I agree with you on 100%. A previous employer had 2 brand new 210 Volvo's delivered on same day. 1 was a joy to operate, the other would make a good operator look like a new boy :Banghead
