I have an Old CAT 90 scraper that has been converted to hyd. Am pulling it with a TD25C. The last heavy scraper operation I was around was a couple of D8's with LeTourneau cable scrapers in the late 60's. Dad would run another D8 pusher to help them load when they were working for us. Trying to build a pond. Have at least 4 types of material to work with. 8 to 10ft. of blow sand on top of 6' of gray clay on top of 6' of dry liver mud on top of red shale/soft sandstone. Plan is to strip off the sand and stockpile the clay to use as liner later. Plan to strip down to a solid shale base and then seal up the sides/ dam face with the clay. Scraper has center "bit" I would call it on the cutting edge. I can drop the bowl in anywhere and cut/load until the bowl is 3/4 full, then I run out of traction. The material doesn't seem to "boil" into the bowl like I thought it should. Is it just a power/traction thing? I know when I have pulled a small 7yd ag scraper with my 4WD farm tractor I either boiled it over the sides or pulled the tongue in two. :) Where does the apron need to be set when loading? Minium/maxium cutting depths? When I unload I drop the cutting edge down to about 6" off the ground, raise the apron, and spread/ eject across the fill. I'm a one man show right now, so would need to hire an operator if push filling would speed things up greatly. Have a 300 hp 4wd tractor with dozer blade to push. Any and all comments are welcome. Thanks Dirt
