MacDon FlexDraper FD140 - Header Operating Variables; Cutting off the Ground

214683 58 Revision A
3.7 Header Operating Variables
Satisfactory function of the header in all situations requires making proper adjustments to suit various crops and
conditions.
Correct operation reduces crop loss and increases productivity. As well, proper adjustments and timely
maintenance will increase the length of service you receive from your machine.
The variables listed in Table 3.11, page 58 and detailed on the following pages will affect the performance of your
header.
You will quickly become adept at adjusting the machine to achieve the results you desire. Most of the adjustments
have been preset at the factory, but the settings can be changed to suit crop conditions.

3.7.1 Cutting off the Ground
The header’s design allows operators to cut crop above the ground in relation to desired stubble height. The cutting
height will vary depending on factors including crop type, crop conditions, etc.
The stabilizer wheel system is designed to minimize bouncing at the header ends and may be used to float the
header to achieve an even cutting height when cutting above ground level in cereal grains. The system produces
even stubble height and greatly reduces operator fatigue.
Cutting height is controlled using a combination of the combine header height control and a stabilizer wheel system
(or stabilizer / slow speed transport wheel system).
If stabilizer wheels are installed, refer to Adjusting Stabilizer Wheels, page 60 to change the wheel position.
If stabilizer / slow speed transport wheels are installed, refer to Adjusting Stabilizer / Slow Speed Transport Wheels,
page 59 to change the wheel position.
