This is a mowing vlog, not a tractor review: the 4066R is the backdrop while an unrelated well-pump crisis takes over the video. The creator's pressure switch fails mid-mow, spiking the system past 100 PSI, and he walks through diagnosing it, explaining how a pressure switch and relief valve work, and swapping the part. Expect little tractor detail and no specs, demos, or buying info; useful mainly for homestead/well-system troubleshooting, not 4066R research.
