It’s always frustrating when you are ready to roll but your technology is not. The most common issues with flow control systems seem to be incorrect rates on the Raven 660 and issues with the hydraulic cylinder moving correctly. Often times, these can be corrected with basic setting changes and fuse replacement.
WRONG/ NO RATE APPEARING ON RAVEN 660
The Raven console provides an actual rate by taking width, speed and volume flow and computing it into volume per acre. Any time you lose one of these inputs you will lose your rate. Check to make sure the speed is reading correctly on the Raven by comparing it to the speed on the tractor. Volume flow (volume/minute) can be a common factor of the rate reading wrong. Check and make sure the volume/minute is a realistic number. If this isn’t realistic, there is most likely a wrong setting that needs fixed.
HYDRAULIC CYLINDER NOT MOVING CORRECTLY
Check to see if the cylinder will move by placing it in manual with constant flow to the hydraulics and toggling between increase and decrease. When testing it in manual, visually look and see if the cylinder is extending (increasing) or retracting (decreasing). If nothing appears to happen check the 2 fuses in the cylinder system located on the large red wire in the cab as well as the grey boost box on the front of the tank.
The majority of problems with flow control systems stem from dirty connections on the wiring
harnesses. Before the season hits, clean connections with electronic cleaner and use di-electric grease to ensure a good connection. Also, be sure the locking collar is completely locked; this will cause a problem if the connection does not stay tight.
