VICKERS RV3 10 S 0 36/29

Designed for applications like refuse haulers, the RV3-10 series valve is well-suited for mobile and industrial settings where you need reliable pressure control.

Harvesters are actually one of the listed applications for this valve, so you're in the right ballpark. It handles up to 350 bar (5000 psi) and flows up to 76 liters per minute, which gives it solid range for the kind of variable demands harvest equipment puts on a hydraulic system. The poppet-style design keeps things compact, so it won't hog space in a tight installation. Worth noting there's no specified port size tied to this particular configuration, so you'll want to confirm your line fittings match up before bolting it in.
