Why is soil building up in front of the cutterbar of my KUHN GMD883 Lawn Mower?
Soil build-up in front of the cutterbar can be due to too much cutterbar down pressure (increase accumulator pressure) or very wet working conditions (adjust main frame height with regards to the ground).
Why is there insufficient cutterbar ground clearance in "headland turn" position on my KUHN GMD883?
Insufficient cutterbar ground clearance in the "headland turn" position can be caused by an incorrect tractor lift linkage setting (see machine attachment) or too long levelling rod adjustment (shorten levelling rods).
Why is there uneven stubble after mowing with my KUHN GMD883?
Uneven stubble can result from several issues: dull or broken knives (replace knives), knives not installed correctly (ensure the arrow on the knife upper face points in the disc's rotation direction), or too low PTO speed (increase speed to 1000 min-1).
What to do if control box switches have no effect on the cylinders of KUHN Lawn Mower?
If the control box switches have no effect on the cylinders, first, ensure the control box is energized using the ON/OFF switch. Next, check if the tractor valve supplies oil continuously. Take the hose in hand and feel if oil flows.
Why is adjusting the hydro-pneumatic accumulator pressure on the move not possible on my KUHN GMD883?
If you cannot adjust the hydro-pneumatic accumulator pressure on the move, the suspension circuit valve is likely closed. Open the suspension circuit valve.
What to do if one switch on the control box has no effect on the corresponding cylinder of KUHN GMD883 Lawn Mower?
If one switch on the control box has no effect on the corresponding cylinder, and if the control valve is operational, the check valve located underneath the control valve is probably defective. Replace it if necessary.
Why is my KUHN GMD883 Lawn Mower having bad ground contour adaptation?
Bad ground contour adaptation can be caused by an incorrect main frame setting (adjust main frame height with regards to the ground), excessive ground speed (reduce ground speed), or insufficient ground pressure (reduce accumulator pressure).
What causes excessive noise from a control or check valve in my KUHN Lawn Mower?
Excessive noise from a control or check valve can be due to a faulty valve (replace the faulty component if necessary) or an insufficient oil level in the tractor tank (check oil level and top up if necessary).
Why do the mowing units on my KUHN GMD883 Lawn Mower not lift?
If the mowing units do not lift, the tractor valve may not be supplying oil at the right pressure. If necessary, replace the faulty component.
Why do the mowing units on my KUHN GMD883 not fold?
The mowing units can only be set into transport position with the machine in headland turn position. Place the machine in headland turn position.
