John Deere 4066R 5 year compact tractor review! The good and bad! #815

A hands-on owner review after five years and nearly 900 hours on a John Deere 4066R cab tractor. Covers specific recurring problems, a faulty fuel sending unit that caused three run-outs, a failed AC blower motor, a cracked fender tied to a redesigned control placement, and a DPF sensor covered under extended warranty. Also addresses regen behavior and the real added cost of hydraulic options not included standard. Best for serious 4-Series buyers weighing reliability and total ownership cost.

An owner-operator sharing long-term hands-on experience from their own property, with a clear but not uncritical loyalty to John Deere based on prior ownership history.
