Section 4: Operating ProceduresTable of ContentsRCR1242, RCR1248, RCR1260 & RCR1272 Rotary Cutter 326-047M2/7/20 23TransportingWARNING!To avoid serious injury or death:• When traveling on roadways, travel in such a way thatother vehicles may pass you safely. Use LED lights, cleanreflectors, and a slow moving vehicle sign that is visiblefrom the back to warn operators in other vehicles of yourpresence. Always comply with all federal, state, and locallaws.• Always disengage power take-off and wait for driveline tostop rotating before raising implement to transport position.1. Make sure driveline does not contact tractor or cutterwhen raising cutter to transport position.2. Reduce tractor ground speed when turning and leaveenough clearance so cutter does not contactobstacles such as buildings, trees, or fences.3. Limit transport speed to 20 mph. Transport only witha farm tractor of sufficient size and horsepower.4. When traveling on roadways, transport in such a waythat faster moving vehicles may pass you safely.5. Shift tractor to a lower gear when traveling over roughor hilly terrain.Blade Engagement & DisengagementCutter blades can lock-up against each other duringstart-up and shut-down especially if the tractor’s powertake-off engagement is “INSTANT ON” and “INSTANTOFF”. Following Blade Engagement and BladeDisengagement instructions below will help eliminateblade lock up.Blade Engagement1. Increase throttle to a speed just enough to get thecutter started without stalling tractor while slowlyengaging drivelines. Use tractor’s power take-off softstart option if available.2. Ensure that all power shafts are rotating and that thecutter is not vibrating excessively after ramping up topower take-off speed for at least 3 seconds. Ifexcessive vibration continues after 3 seconds at fullpower take-off speed, disengage power take-offimmediately, shut down tractor, and remove switchkey.3. Check blades for a lock-up situation. Block cutterdeck up before working under the unit. Unlockblades, remove support blocks, and repeat “BladeEngagement” instructions.Blade Disengagement1. Slowly decrease throttle speed until engine idlespeed is reached and then disengage power take-off.2. Engage tractor park brake, shut tractor engine offand remove switch key. Stay on tractor until bladeshave come to a complete stop.Field OperationDANGER!To avoid serious injury or death:Clear area to be cut of debris and other unforeseen removableobjects before cutting. Mark non-removable hazards such astree stumps, post stubs, protruding objects, rocks, drop-offs,holes, etc. with a visible flag.1. Thoroughly inspect area to be cut for debris andunforeseen objects. Mark any potential hazards.2. Follow “Blade Engagement” instructions on thispage to start cutter blades turning.3. Optimum ground speed depends on density ofmaterial being cut, horsepower rating of tractor, andterrain. Always operate tractor at cutter’s full ratedpower take-off speed in a gear range that allows thecutter to make a smooth cut without lugging tractordown, usually between 2 to 5 mph.4. Stop traveling and disengage power take-off after thefirst 50 feet of cutting. Check cutter levelness andcutting height to make certain it is adjusted properly.5. Do not engage power take-off with 3-point cutter fullyraised.6. Periodically disengage power take-off, shut downtractor, remove key, and check for foreign objectswrapped around the blade spindle. Block cutter deckup before removing objects.7. Frequently inspect cutter for loose bolts and nuts.Tighten all loose bolts and nuts as indicated in the“Torque Values Chart” on page 36.8. For additional information, see “General OperatingInstructions” on page 24.IMPORTANT: Maintain correct power take-off speed.Loss of power take-off speed will allow blades toswing back resulting in ragged, uneven cutting.IMPORTANT: Your cutter is equipped with freeswinging cutting blades to reduce shock loads whenstriking obstacles. However, it is best to avoid strikingobstacles to extend cutter and blade life.NOTE: Do not cut in wet conditions. Wet materialwill build up on the deck underside creating poordischarge, high wear, and additional horsepower.NOTE: Periodically disengage power take-off, turnoff tractor, remove key & check for objects wrappedaround blade spindle. Block deck up beforeremoving objects.Frequently inspect cutter for loose bolts and nuts.Tighten all loose hardware as indicated in the“Torque Values Chart” on page 36.
