Page 10: General Arrangement
GENERAL ARRANGEMENT Overview Twose Series Maxicut Flex Wing Mowers are available in cutting widths of 4.6 or 6.0 metre. The cutting height is adjusted hydraulically; a self-levelling system ensures the blades remain parallel to the ground irrespective of cutting height. The wings are also raised and lowered hydraulically with power being supplied from the tractors 3 spool valves.
Page 11: Safety
SAFETY Safety 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 12 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 13 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 15: 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.
Page 16 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 17 IMPORTANT MINIMUM ENGAGEMENT OF PTO IS 150MM 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. a Fit PTO to tractor ensuring locking peg on the splined coupling is fully engaged. b Attach PTO guard check chains to tractor and machine.
Page 18 In case of valve or cylinder malfunction, contact your local dealer. If it becomes necessary to remove the piston from the cylinder, apply a few drops of “Loctite No 227” to nut before replacing. Clutch Adjustment 3 slip clutches are fitted to protect the blades, drivelines, gearboxes, tractor etc. Machines are supplied set to a low torque and clutches should be adjusted prior to first use, as detailed in Maintenance Section.
Page 19: 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 20 Pre-Start Checks Before operating the machine it is advisable to carry out the following checks. a. Check that the blades are free of obstructions especially pieces of wire. b. Check that the blades are in good condition and securely attached. c.
Page 21 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. When this occurs, reduce the tractor ground speed but maintain the PTO rpm.
Page 22 To check maximum joint angle, connect cutter to tractor. Do not connect driveline at this time. Start tractor and make a maximum turn to the 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.
Page 23 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 1/2 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 24 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.
Page 25 WARNING Use the tractor warning lights, reflectors and other devices for adequate warning to the operators of other vehicles. Comply with local government regulations at all times. IMPORTANT On 4.6m (15ft) models an alternative hole provided reduce transport width of the machine (see illustration).
Page 26: 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 27 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 28 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 29 Blade Servicing Inspect blades before each use to determine that they are properly installed and in good condition. Replace any blade that is bent, excessively nicked, worn or has any other damage. Small nicks can be ground out when sharpening. WARNING Use only original equipment blades on this mower.
Page 30 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 31 5. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates should break loose (check the mark). 6. Turn tractor off. Inspect mark on plates – should be out of alignment, showing that slip clutches have operated. If not, completely dismantle and clean all mating surfaces. 7.
Page 32 TORQUE SETTINGS FOR FASTENERS The Chart below lists the correct tightening torque for fasteners. The Chart should be referred to when tightening or replacing bolts in order to determine the grade of bolt and the correct torque unless specific torque values are assigned in the text of the manual. Recommended torque is quoted in Foot-Pounds and Newton-Metres within this manual.
Page 33 Hub Assembly When attempting taper roller bearing adjustment it should be noted that there is not a specified torque setting for the shaft crown nut since there should always be axial play (end float) with a taper roller bearing set up. On the hub –...
