How much rock damage can u live with and how big a saga is it to replace the feed accleratorIJ Ie are a few small dents acceptableIJ How well does the rock trap work on the sts machinesIJ Our country is uneven and prone to some small gibber rock in areas and no matter how good an operator you are, harvesting chickpea's on the deck, sooner or later your going to pick up some dirt or small rocks or the odd small stick. Would rather a machine without a chopper now. Had one on current machine and just seem heavy on fuel and don't spread as well as the standard hydralic spreaders on the sts machines. What kind of machine did you have before the 9760IJ Are you expecting much of a fuel consumption differenceIJ Most of our harvesting in wheat are at higher speeds (6 mile plus) due to the lighter crops but this also makes the hydrostatics work pretty hard, particularly is softer country so would expect an increase in fuel consumption with a lager machine which is another drawback.
