How Often Should You Grease a Mini Digger’s Swing Bearing and Bucket Linkage?

[Buildscope]

Hey folks, I’ve got a few questions about mini diggers and excavators. I’ve been running a small 3–4 ton machine, and it’s great for tight spaces, but I’m still learning its limits. How often do you check or grease the swing bearing and bucket linkage? I’ve heard different answers, and I don’t want to overdo or underdo it. Any advice from people who’ve been running these for a while would be appreciated.
