7.7 CUTTING PERFORMANCE _____________________________________________
NOTE:
Due to the low power requirement of the Mounted 214, it is quite acceptable to use the tractor with the engine
speed reduced to as low as 900 rpm. This may be necessary when sparse grass of uneven height is being cut. It
is also convenient for manoeuvring, reduces noise and improves operator comfort, and reduces tractor engine
wear.
Slow cutting cylinder speeds reduce cylinder and bottom blade wear.
It is necessary to use increased engine speeds to achieve satisfactory cutting and grass discharge in wet, lush
grass conditions or where higher cuts/yard are required at reasonable forward speeds.
7.8 HOW TO REMOVE A BLOCKAGE FROM CUTTING UNITS____________________
It is important to note: there will be remaining hydraulic pressure within the system that can cause the cutting
cylinder to rotate when the obstruction is removed. Therefore keep your hands, feet and clothing away from
cutting units at all times.
1)
Disengage the power to the cutting units with the cutting unit switch.
2)
Keep the cutting units lowered to the ground (Wait for the remaining cutting cylinders to stop rotation).
3)
Lift the cutting units into the "Transport Position", lock in position use the transport latches fitted on your
product.
4)
Remove your foot from the forward/reverse pedal.
5)
Set the parking brake.
6)
Move the throttle control lever to the slow position.
7)
Turn the ignition key to the off position and remove the key.
Make sure correctly selected PPE is worn before you clear the obstruction.
8)
Use the Ransomes Jacobsen "Cutting Unit Tool" part number 4184540 See below or stout stick, put into
the cutting cylinder between the blades.
9)
Rotate the cylinder with either the "Cutting Unit Tool" or "Stout Stick" until the obstruction has been
removed.
10) Inspect all the cutting surfaces for damage, when necessary replace the damaged components.
7.9 BACKLAPPING _______________________________________________________
•
Backlapping is a process which will lightly grind the reel to the bedknife whilst mounted on the mower.
•
If significant amounts of metal are to be removed then the cutting unit should be reground on a specialised
grinding machine.
•
Before any backlapping is carried out, Ransomes Jacobsen recommends that the backlapping process
should be risk assessed as a workshop process by the manager of the machine.
