G014563 Figure 32 G014423 Figure 33 Checking the Cylinder to Bedknife Contact MK3 Floating cutterhead 8 inch (20 cm): When the mower is set up with floating cutterheads the height of cut is gauged by the front and rear rollers. The cutterhead is allowed to pivot fore and aft as well as laterally. This arrangement is recommended for high quality grass areas and performs well where grass is short and the ground undulations are severe (Figure 34).
MK3 Fixed cutterhead 8 inch (20 cm) and Fixed cutterhead 10 inch (25 cm) Pivot knuckle fixing: Secure the bolt in the front fixed hole position in Figure 37 as shown. 1 G014425 G014427 Figure 35 Figure 37 1. Front fixed hole position WARNING Height of cut adjustment: The height of cut is gauged by the position of the rear roller. Turn the adjusting nut assembly both ends clockwise to decrease height of cut or anti-clockwise to increase height of cut (Figure 38).
1 Ensure that all cutterheads are set at the same height of cut by either referring to the indicator rings (Figure 39 ) or by using a height of cut gauge across the full width of each cutterhead for greater accuracy as shown. 2 4 3 G014431 1 Figure 41 = 1. Adjusting nut assembly 3. Height-of-cut 2. Adjusting nuts 4. Indicator rings Important: Do not attempt to unlock the nut assemblies. G014429 Figure 39 To alter the front roller position loosen bolts.
Centre Cutterhead Height of Cut Correction Adjustment With all cutterheads set at the same HOC via the indicator rings, it may be noticeable that the center unit produces a higher cut finish compared to the wing units. The center unit is pulled and the wing units are pushed, this presents marginally different cutting angles relative to the ground.
Engaging the Cutterhead Drive 4. Stop the engine and remove the ignition key to isolate all power sources and check that they are stopped. 5. Release all stored energy devices. 1 6. Check that all moving parts are stationary. 2 7. Using a suitable strong wooden instrument, remove the blockage. Make sure that the wooden instrument is properly supported in the cylinder and avoid the use of excessive force to prevent damage. 3 8.
Folding the R.O.P.S. WARNING Be careful lowering and raising the R.O.P.S frame to prevent entrapment of fingers between fixed part and pivot part of the structure. The R.O.P.S frame may be folded down to allow access into areas of restricted height. WARNING • Keep all nuts, bolts and screws correctly torqued ensure While the R.O.P.S frame is folded down it does not provide any protection in the event of a roll-over and should not be considered as a Roll Over Protective Structure.
Operating Tips WARNING Take care when travelling over obstacles such as roadside kerbs. Always travel at slow speed over obstacles to prevent damage to the machines tyres, wheels and steering system. Ensure that tyres are inflated to the recommended pressures. Familiarization Before mowing grass, practice operating the machine in an open area. Start and stop the engine. Operate in forward and reverse. Lower and raise the cutting units and engage and disengage the cutterheads.
