VICKERS CV1-16V-P-0-100

This Vickers check valve is rated for a maximum pressure of 350 bar (5000 psi), so it should be suitable if your system operates within that limit. It's designed for mobile applications like refuse haulers, indicating it can handle demanding conditions.

Harvesters are actually one of the listed applications for this valve, so you're in the right ballpark. It's a poppet-style check valve rated up to 350 bar (5000 psi) and handles flow up to 151 liters per minute (about 60 US gpm). For mobile equipment like harvesters, those ratings give you solid headroom. The CV1-16V-P-0-100 is part of the Vickers CV1-16 and CV11-16 series, so as long as your system is spec'd for that series, it should be a proper fit.
