Hello everyone this is my first post and I love all the advise that i can read from everyones posts on this site.. I have a question about finish blading with gps, the company i work for purchased gps for equipment about 3 years ago started with the topcon but just recently we switched to trimble because of tighter tolerances on an airport project we are doing. It seems like if i try to just "flip the switches and go" like the caterpillar guy said the blade tends to be really jumpy and that is after i get the grade watered and compacted i like to leave it about a tenth high then cut one last time to grade and compact again. We have had the caterpillar guys come out and look at the machine and they say everything is how its supposed to be. I end up usually only running the side with the mast on automatic and running the other side manually, I tried running both sides but our grade failed tolerances which is 3 hundreds, has to pass straight edge, 100% compaction, and pass proof roll. Is there anything i can do different or is it a machine issue? Any help is appreciated. The machine is a cat 140H tier 2 with about 8500 hours and i would call it good condition not great. I have been running a blade for about 4 years now. And its all the newest equipment from trimble to my knowledge with the robot that follows the prism on the mast.
