Whether you need one depends on the \u003cstrong\u003etype of motor\u003c\/strong\u003e inside the attachment, not what kind of attachment it is: \u003cstrong\u003episton motors need a case drain, gear motors usually do not.\u003c\/strong\u003e This trencher uses a piston motor. Run it without a case drain line and oil pressure builds up inside the motor and destroys the seals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf your machine does not have a case drain port, tell us before you order.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eSpotting A Case Drain Port Yourself\u003c\/h3\u003e\n\u003cp\u003eCount the hydraulic lines at the front of your loader arm. Two lines (supply and return) means no case drain. A third line usually means it has one — case drain lines typically run through a smaller coupler, around 3\/8 in across, sitting next to the two larger supply and return couplers.\u003c\/p\u003e\n\u003cp\u003eA shortcut worth knowing: \u003cstrong\u003emost factory high-flow packages include a case drain port; most standard-flow-only machines do not.\u003c\/strong\u003e If your machine is high flow, look for that third small coupler before assuming you need to add one. If it is standard flow only, plan on having a case drain kit installed — or tell us and we will point you to one.\u003c\/p\u003e\n\u003ch3\u003eWhich teeth for your ground?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSand and loam (soft, loose soil)\u003c\/strong\u003e — standard cup teeth.
