To adjust the reel drop rate, follow these steps:
1. Lower header to ground, stop the engine, and remove
the key.
2. Open the left cab-forward side maintenance platform.
Refer to
5.5.1 Opening Platforms (Standard Position),
3. Locate valve (A) installed at port D, it controls the reel
drop rate.
NOTE:
This valve is only installed with a draper header.
4. Loosen setscrew (B) then refer to the following options:
• Turn cap (C) clockwise to decrease the drop rate
• Turn cap (C) counterclockwise to increase the
drop rate
5. Check drop rate and adjust as required
6. Tighten setscrew (B).
NOTE:
To reset to factory specifications, fully close the needle
valve and open it four turns counterclockwise.

Figure 5.210: Hydraulic System
Traction Drive Hydraulics
The windrower transmission consists of two variable displacement axial piston hydraulic pumps, one for each
drive wheel.
The pumps are driven through a gearbox from the engine. Each pump requires charge flow in order to
• Make up for internal leakage
• Maintain positive pressure in the main circuit
• Provide flow for cooling
• Replace any leakage losses from external valving or auxiliary systems
The charge pressure is monitored. The cab display module (CDM) sounds a tone and displays a flashing warning
if charge pressure drops below 250 psi (1725 kPa). Refer to
3.18.4 Cab Display Module (CDM) Warning/Alarms,
