OPERATING THE MOWER CONDITIONER
7.7 Cutting Height
Cutting height is determined by a combination of the angle of the cutterbar/mower conditioner and the skid
shoe settings.
Cutting height should be adjusted for optimum cutting performance without allowing excessive build-up of mud and
soil inside the mower conditioner that can lead to poor crop flow and increased wear on cutting components.
Choose an angle that maximizes performance for your crop and field conditions. Refer to Section
.
Optional adjustable skid shoes are available to also provide different cutting heights. Refer to Section
.
• Lowering the skid shoes or decreasing mower conditioner angle increases the cutting height. This may be
desirable in stony conditions to reduce damage to cutting components. Also, a longer stubble length helps
material dry faster.
• Raising the skid shoes and increasing mower conditioner angle allows the crop to be cut lower.
To minimize damage to cutterbar components, scooping soil, or soil build-up at the cutterbar in damp conditions,
mower conditioner float should be set as light as possible without causing excessive bouncing.
When the float setting is light, it may be necessary to use a slower ground speed to avoid excessive bouncing and
leaving a ragged cut.
7.7.1 Adjusting the Skid Shoe Height
DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine: stop engine, remove
key, and engage lift cylinder lock-out valves before going under machine for any reason.
1. Raise mower conditioner fully, stop engine, and
remove key.
2. Engage lift cylinder lock-out valves.
3. Remove lynch pin and remove adjuster pin (A) from
one side of skid shoe (B).
4. Hold skid shoe and remove lynch pin and adjuster
pin (A) from other side.
Position shoe at desired
position, and reinstall adjuster pins (A). Secure with
lynch pins.
5. Repeat

6. Check mower conditioner float as described in Section
7. Adjust mower conditioner angle to desired working
position using the machine's mower conditioner angle
controls. If angle is not critical, set it to mid-position.
