9.1 General on Driving
The following should be observed when the Big M is
driven:
Due to the rear wheel steering the handling of the Big
M requires a certain time to get used to.
the handling of the Big M is different in level I and II
If an error message appears in the Info Centre stop
immediately and rectify the fault. If you cannot rectify
the fault inform the customer service or your KRONE
dealer.
Never drive with an engaged parking
brake.

Driving forwards from standstill:
After starting the engine the gear box is in neutral position.
Press activation button (1) at the rear side of the driving
lever.
Moving the driving lever forwards will cause the machine
to move forwards and accelerate.
If the lever is released it will return to its central position
automatically. The speed remains constant.
Moving the driving lever backwards will decelerate the
machine. It is decelerated until it comes to a standstill
by adherence.
9.7 Setting the Accelation
Behaviour
Using the switch (1) is possible even while driving to select
four different acceleration levels.

If the ground drive has been killed, never wait longer than 5 seconds to reset the drive lever to
Neutral, then select a lower gear.
The drive moment which acts on the drive wheels depends on the oil pressure in the hydrostatic
drive system. If the pressure requirement becomes higher than the pressure in the hydrostat
system, the pressure relief valve will open and the
self-propelled high performance mower-conditoner will not move.
As soon as the required drive moment decreases (this is achieved by selecting a lower gear) the
self-propelled high performance mower-conditoner will drive on again.
9.9 Preventing Overheating of the Hydrostat System
If the hydrostat system overheats an acoustic warning signal occurs. Turn off engine and establish cause of overheating.
Then improve the effectiveness of the hydrostatic ground drive by selecting a lower shift step this will reduce the oil
temperature.
Fast change of direction
The Big M II decelerates to a standstill, automatically lifts
out all three mowers and accelerates in the opposite
direction (approx. 70% of the previous driving speed).
while driving tap the driving lever to the left and simulta-
neously press the activation button on the rear side of
the driving lever.
Driving backwards from standstill:
After starting the engine the gear box is in neutral position.
Press activation button (1) at the rear side of the driving
lever.
Moving the driving lever backwards will cause the
machine to move backwards and accelerate.
If the lever is released it will return to its central position
automatically. The speed remains constant.
Moving the driving lever forwards while driving backwards
will decelerate the machine until it comes to a standstill
by adherence.
(only possible during field operation (fast reversing))
If the road safety switch is in field position
a reversing alarm occurs when the driving
lever is pulled backwards from neutral
position (reversing).

10 Mowers General
10.1 Proper Use of the Mowers
The disc mowers are designed solely for normal
agricultural use (use in accordance with specifications).
Any use of the machine for other purposes is deemed not
to be in accordance with specifications. The manufacturer
bears no responsibility for any resulting damage such
use is entirely at the operator's risk.
Use in accordance with specifications also includes
observing the operating, maintenance and service
instructions prepared by the manufacturer.
The disc mower must only be used, maintained and
repaired by personnel who are acquainted with the
machine and have been informed of the dangers involved.
The applicable accident prevention regulations and all other
generally recognized safety, health and road traffic
regulations must be observed.
Any unauthorized alterations to the machine render any
liability for damage undertaken by the manufacturer null
and void.
The mowers are suitable for and intended for cutting crops growing on the ground!
The mowers are not suitable for mowing embankments!
Maintain an adequate safety distance to the cutting tools during operation.
The support skids must rest on the ground before start-up and during work!
Stones and similar objects can also be slung even when the mower is used correctly.
Therefore no-one may remain in the danger area! Special care should be taken while
working near roads and buildings.
Check the safety guards regularly. Worn or damaged safety guards should be replaced!
The protective equipment on the mower, e.g. guards and guard plates, protects against
flying stones and similar objects as well as prevents dangerous parts being accessed. They
should therefore be brought into protection position before work starts.
Keep clear of the slewing range of the mowers while they are mowed from transport into
operating position and vice versa.
The accident prevention regulations must be observed.

travel. If the road safety switch is in field
position, the mowers are automatically
lifted out during reversing.
10.2.1 Special Safety Instructions
10.2.2 Guards on the Mowers
Fold down the side plates (1) before
operation.
Check the safety guards (2,3) regularly.
Replace worn or damaged safety guards.
The protective equipment on the mowers,
e.g. guards and guard plates, protects
against flying stones and similar objects as
well as prevents dangerous parts being
accessed.

The cutting height is set individually for each mower:
The tilt of the disc mowers and thus the cutting height is
adjusted via threaded spindles. There is an extension pipe
in the tool box.
Front mower
Cutting height can be varied by adjusting top link (1).
Longer top link arm = shorter cutting height
Shorter top link arm = longer cutting height
Adjustments must always be made
only when the drive is switched off
and the tractor engine is at a stand-
still! Remove the ignition key!
Secure the tractor against rolling
away.
10.2.3 Setting the Cutting Height
Side mowers
Disassemble the lynch-pin (1).
Remove the securing ring (2).
Adjust the direction of adjustment ratchet (4) rotation on

Mowers
Side mowers
The side mowers are relieved via four extension springs (1)
on the left-hand and right-hand arm.
The ground pressure can be set by moving the pin (2).
Raise the side mowers above the stand-by position
so the compensation springs are relieved.
First remove the lynch-pin and then pull out the pin (2).
Pin further to the left: lower ground pressure
Pin further to the right: higher ground pressure
Insert pin (2) and secure with lynch-pin
Maximum relief when driving on the
road. Mount bolts in stage 3 (medium
bore).
10.2.4 Setting the Ground Pressure
The ground pressure of the cutterbars is adapted to the
local conditions using compensation springs. In order to
protect the turf the cutterbars should be relieved to such an
extent that they do not jump during mowing and do not
leave any marks on the ground.
The adjustment of the compensation
springs must only be carried out when
the front disc mower is in transport
position. In working position, the
compensation springs are under a high
tension.
Taking off the compensation springs
when the mower is in working position
can cause serious injury.
The lower screw-in sections of the
compensation springs must be
completely screwed in.

Straighten bent tines.
Replace broken tines.
Check bearing pins and bushing on tine mountings. To
avoid losing tines, replace bearing pins and bushings in
good time!
The conditioner shaft turns at up to
approx. 1000 r.p.m. Bent and broken
tines cause unbalanced rotation. For
this reason replace broken V-tines
immediately.
10.2.7 Setting the Conditioner Cover Plate
(Big M CV)
The conditioning effect of the mowing crop can be influenced by adjusting the conditioner cover plate using the
screw (1). Turning clockwise increases the conditioner
effect with an increase in power consumption. Turning the
screw anticlockwise reduces the conditioning effect.
