My L3010 with BL4690 started to knock and lose power under load. I thought my HST hydraulic fluid was low but I’ve now overfilled it, so it’s obviously not that causing the knock and stutter in the PTO shaft. Everything works well on the hoe, and everything including the loader on the tractor works, but when I use the hoe under any load the PTO knocks and stutters until I let off the controls. Could be the PTO lever cable needs adjustment? Any other ideas? Thanks! Here’s a video of the issue.
