A seed cart that meters wrong plants a crop wrong, and you find out months too late. That is the failure the Flexi-Coil 1720, 2320 service manual PDF exists to prevent: 252 pages of factory service data covering both seed cart models under OEM ID GH-003.4. Wiring diagrams trace every monitor sensor circuit back to the console, and hydraulic schematics map the fan drive plumbing before you crack a single fitting. Metering takes up the largest share of the book, from roller and clutch service through drive ratio sprockets and chain. Set the shaft sensor gap at 1/8 inch, hold the wrap spring clutch latch arm to sprocket clearance at 1/32 inch, and confirm the meter drive box turns 109.5 rpm at rated input. Guess a clearance instead, and the monitor lies to you all season. Bookmarked and text-searchable, this download is ready before the seed truck backs in.
