Cutting hay with the sickle bar mower and RK37.

An owner documenting their first hay cut of the season with an RK37 and sickle bar mower. The most useful stretch covers a mid-job belt-slippage fix, exactly which adjustment bolt to use, how to tighten it, and what socket sizes fit. It also shares hard-won tips on cutting-bar angle and PTO RPM. Best for RK37 owners troubleshooting a sickle bar mower, not a buying-decision video.

An owner-operator sharing real-time homestead work, so expect candid trial-and-error rather than polished instruction.
