Rock size is a key factor when selecting ejector size - recommended 2 - 2,5 time expected rock size on the ejector to prevent clogging Slope/ levelling is easy with stone as the chance of backfilling is limited (as compared to sand) Usually +/-5 cm is achievable with sandy material, but tolerances for rock removal are dependent on stone size A key challenge is that removed rocks accumulate behind the machine, while transport over longer distances (in excess of 50m) will affect performance. Better performance rate can be achieved without use of exhaust hose. Usually visibility is good while dredging in rocks Rocks can be backfilled if required
