Self-Diagnosis and Recalibration of Hydraulic System

What happens here

After the professional repairs, the owner discovered that the tractor's 3-point hitch was still not functioning. Through further troubleshooting, he identified that one of the hydraulic remote arms was accidentally engaged. This engagement was causing hydraulic fluid to be continuously pushed, preventing the 3-point hitch from moving. He learned that the TYM T1104 tractor features a Bosch electronic lift system. By simply disengaging the hydraulic arm, he was able to recalibrate the system in approximately 30 seconds, resolving the issue that had caused him an hour and a half of frustration.

Goal: Identify and resolve the hydraulic 3-point hitch issue through recalibration.
