Just called my brother to go fire up the sprayer and see if he could get auto
steer back on straight track. with the oil cold he said it tracked just fine and worked 100%. So fairly confident it's the eh valve internal leakage when the oil heats up. mother deere has the proportional valve controller (EH) in stock part # RE 333009 and is $1558.58 ouch. the entire block plus valve is over $5500.00
