4.3.6 Windrower Operation
WARNING
• Before starting engine, securely fasten your seat belt and ensure trainer’s seat belt is fastened
if occupied.
• The seat belt can help ensure your safety if it is used and maintained.
• Never wear a seat belt loosely or with slack in the belt system. Never wear the belt in a twisted condition
or pinched between the seat structural members.
WARNING
• Avoid driving the machine with header removed. Removing header decreases the weight on drive
wheels, reducing steering control.
• If necessary to drive machine with header removed, use transmission field speed range, do NOT exceed
1500 rpm engine speed and avoid loose gravel and slopes.
• Never use windrower as a towing vehicle when header is removed, except as instructed in Towing
Header with Windrower, page 124 . There is insufficient weight on the drive wheels to provide steering
control.
• Because of windrower shape characteristics, a roll-over protected (ROPS) cab is not required. If
operating with header removed, be aware that cab structure will NOT withstand a roll-over.
13. Display flashes voltage reading with single loud tone. Repeats every 30 minutes until condition is fixed.
