you need to carry out the hydraulic lift calibration. do this by turning all your edc panel knobs fully clockwise, disconnect the pickup hitch connecting rods (this allows the lift arms to raise fully during calibration)start tractor, set engine revs to 1200 rpm, pull the main quadrant lever in the cab fully up until the lift links fully raise, then lower the quadrant lever right down to its lowest position (not into the external lift/lower switch notch right at the bottom though) then lift the same lever back to the top again. the lcd on the right hand of the dash should now have a value of 99 link fully up & 0 links fully lowered. with the engine still running, lengthing the pickup hitch rods & refit them to the tractor. once fitted shorten rods equally until the pickup hitch lifts off the release hooks but don't shorten the rods too much or the hydraulic pump will blow off & then wear out. once done switch off & start up as nomal. error 24 should be gone. good luck!
