SAFETY Safety Information Read, Understand and Follow the Safety Messages - Serious injury or death may occur unless care is taken to follow the warnings and instructions given in the safety messages, CAUTION! The lowest level of Safety Message; warns of possible injury. WARNING! Serious injury or possible death.
Page 19 SAFETY WARNING! While the tractor is running all personnel should keep well clear of the area around the machine as there are numerous crushing, shearing, impact dangers caused by the machine operation. DANGER! Do not operate with wings raised off the ground. Operating with the wings raised exposes the blades and can cause objects to be thrown and there is also danger of entanglement in or being hit by rotating blades.
Page 20 SAFETY WARNING! Periodically inspect all moving parts for wear and replace when necessary with authorised service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order.

Page 22: Installation
INSTALLATION Preparing The Tractor A few simple tasks will be necessary to prepare your tractor for use with the rotary mower. Adjust drawbar length according to type of hitch fitted - see Fig 3 or 6. Remove cap from PTO shaft Ensure tractor PTO guard is in place Set tractor tyres out to 1500mm (60”) dimension between tyres.
Page 23 INSTALLATION WARNING: Failure to adjust the drawbar to the CORRECT LENGTH, failure to PROVIDE DRAWBAR CLEARANCE sufficient for short turns and/or failure to ATTACH CLEVIS TO THE DRAWBAR correctly and securely MAY ALLOW THE MOWER TO SEPARATE FROM TRACTOR AND/OR THE DRIVELINE HALVES TO SEPARATE WHICH CAN CAUSE SERIOUS BODILY INJURY OR DEATH TO THE OPERATOR OR OTHERS.
Page 24 INSTALLATION IMPORTANT: MINIMUM ENGAGEMENT OF PTO IS 400MM IN THE WORKING POSITION -THIS MEASUREMENT MUST BE TAKEN INTO ACCOUNT WHEN SHORTENING THE PTO SHAFT. Before fitting PTO shaft to tractor, grease the sliding drive shafts and bearing units. Fit PTO to tractor ensuring locking peg on the splined coupling is fully engaged. Attach PTO guard check chains to tractor and machine.
Page 25 – this will allow the mower sections to follow the contour of the land. For additional information on this subject contact the McConnel Service Dept. or your local dealer. Keep hoses and couplings free from contamination. Never leave a disconnected end of hose open.
Page 26: Operation
OPERATION HEIGHT OF CUT To achieve maximum cutting efficiency and provide the most uniform cut the mower should be operated with the rear slightly higher 12mm - 20mm (1/2” - 3/4”) than the front. IMPORTANT: Avoid very low cutting heights. Striking the ground with blades gives the most damaging shock loads a mower can encounter and will cause damage to mower and driveline.
Page 27 OPERATION PRE START CHECKS Before operating the machine it is advisable to carry out the following Checks. Check that the blades are free of obstructions especially pieces of wire. Check that the blades are in good condition and securely attached Ensure all guards are in position and in a serviceable condition.
Page 28 OPERATION CUTTING TIPS Always operate the PTO at recommended rpm when cutting. This is necessary to maintain proper blade speed and to produce a clean cut. Under certain conditions, tractor tyres may roll some grasses down and prevent them from being cut at the same height as the surrounding area.
Page 29 OPERATION To check maximum joint angle, connect cutter to tractor. Do not connect driveline at this time. Start tractor and make a maximum turn to left until tractor tyre almost contacts frame. Then check joint by holding driveline yoke above PTO shaft and then angle driveline yoke until it stops. There should be approximately a 10-degree difference between centre line of yoke and PTO shaft, (see fig 10), If not, check drawbar length and shorten if necessary.
Page 30 OPERATION Check position which places driveline at maximum extended length and at minimum compressed length. The minimum compressed length should always maintain 40mm (1-9/16”) clearance, if not, shorten as described in fig 12. If driveline cannot be shortened and still maintain ½ PU dimension engagement, when at maximum extended length, then the operator should be aware of it, so the operator can recognise the terrain conditions that might cause problems (avoiding possible damage by disconnecting driveline from tractor) and cross the terrain in a different manner.
Page 31 OPERATION If you have a condition where you tractor will be going up a steep incline with your mower still on the flat area or coming down the opposite incline, you have a potential problem - see fig 15. The correct preventative measure is to instruct the operator to cross this kind of terrain at an angle - see fig 14.
Page 32 OPERATION CAUTION: Do not exceed18 mph (30Km/h) with pneumatic tyres (See maintenance section). WARNING: Use the tractor warning lights, reflectors and other devices for adequate warning to the operators of other vehicles. Comply with local government regulations. IMPORTANT: On 4.6m (15 ft) machines an alternative hole is provided to reduce the transport width of the machine (see illustration).
Page 33: Maintenance
MAINTENANCE MAINTENANCE Before operating your rotary mower, make sure it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and trouble free operation. WARNING Always disengage the PTO before raising the rotary mower for transporting or making adjustments.
Page 34 MAINTENANCE HITCH ASSEMBLY The hitch pins attach the drawbar assembly to the centre section and should be checked regularly for signs of wear or cracking - replace as needed. The drawbar 25mm (1”) bolt fastens to mower to the tractor drawbar. When the mower is un-hitched and this 25mm (1”) bolt is removed, examine for signs of cracking or wear.
Page 35 MAINTENANCE DIVIDER GEARBOX The test plug for the divider gearbox is located on the right side of the input shaft. The filler pressure relief plug is on top of the gearbox – see fig 4. CAUTION Do not over-fill. If gearboxes are filled above test plug level, pressure under working conditions may cause the grease seals to leak.
Page 36 To remove blades for sharpening or replacement, remove the cover plate on deck of the machine near the gearbox. Remove the locknut from blade bolt. Note: On SR15-6 models the blade bolts are left-hand threads. NOTE: Inspect the locknut after removal and replace if the threads are damaged.
Page 37 MAINTENANCE BLADE CARRIER REMOVAL Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade carrier is loosened. Use a suitable two-jaw gear-puller to pull carrier off tapered gearbox shaft. If A gear puller is not available use A long bar inserted through blade bolt access hole with end against rotor bar.
Page 38 MAINTENANCE Set the engine speed at 1200 rpm. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates should break loose (check the mark). Turn tractor off. Inspect mark on plates – should be out of alignment, showing that slip clutches have operated.
Page 39 HYDRAULIC HOSES Replace pinched and damaged hydraulic hoses at once. Tighten any hydraulic fitting with fluid leaking from it. Care must be exercised when tightening hydraulic fittings as over tightening can cause the fittings to fracture and require replacement fittings. When refitting hoses avoid kinks and sharp bends and ensure that hoses do not chafe on sharp edges.
Page 40 MAINTENANCE PROPER TORQUE FOR FASTENERS The chart below lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text. RECOMMENDED TORQUE IN FOOT POUNDS (NEWTON-METERS) UNLESS OTHERWISE STATED IN THE MANUAL TORQUE VALUES FOR IMPERIAL BOLTS...
