Questions and answers
My feed rollers lock in reverse will lock hyd sys in that direction
A possible cause for the feed rollers on a Morbark M12RX to lock in reverse and affect the hydraulic system is the activation of the auto reverse valve. This valve stops the feed wheel when low engine RPMs are detected, which could trigger the rollers to shift direction or stop. Additionally, issues such as hydraulic pressure not being relieved before service, faulty valve bank components, leaks in fittings or hoses, or worn wiring could also affect the hydraulic system and feed roller operation.
