Gentlemen, Looks confusing, so just could not resist. Just wanted to add some considerations to your original question about building a pond, the first answer you recieved is probably the best one. There does not apprear to be a lot a familiarity on your part with moving dirt. Motor scrapers are great when you have dry solid ground, no ground water, no rain clouds and a longer distance to haul, this is always been good method because your not handling the dirt twice, but to be effective you will need a push cat, twin engine or not. Taking the previous comments into consideration, does not matter how steep the hole or pond is, you can never cut steeper than the machine can get out of, any these machines are powerful and are designed to haul dirt up hill and down hill providing it is dry. If you want super steep sides after, then clean it out with a track hoe, and load that in the scraper, simple. If you have never ran a motor scraper and you attempt this task and it starts raining you will regret both choices the running the motor scraper and the rain. Rubber tired machines are NOT good in wet or rainy ground. When you say "we" are you attempting to do this soley on your own, or do you have helpers?? If you are totally on your own, and you want to do this by yourself with your own money, then a Cat and scraper, or take up the fellows offer about D8's and the 80 pans. This has been a tried and proven method since the 1930's-40's, our counrty was built with cat's and scrapers and motor scapers, you'll be a lot happier if it rained on your project. That is why pratically every cable scraper has been saved and coverted to hydraulics, Model 80 pans were last made in about 1954 and they are still working. If for some reason it all came to an end due to unforseen circiumstances, like huge water, or rocks then you can always use a hoe and doze it away after or loads trucks. Nothing wrong with Hoes and trucks, they are big production with lots of folks busy and you will still need a dozer for your project, these are best for severve conditions, or limitations such as, small limiting areas, slopes, trees, mud, rocks, lakes, narrow road building, communities, loading hauling for great distances. Same goes for also buying a hoe, you should know something about them, including running one, a Steel Tracked (Cat and Scraper for short hauls) in some folks eyes maybe slower but it is pretty forgiving, fool proof and very effective, and if you choose you could do this whole project all on your own. Good Luck with the pond Cheers!
