During the busy alfalfa harvest season, every second counts when the baler malfunctions. Mastering quick diagnosis and troubleshooting methods for common problems can help operators quickly restore production and avoid missing the optimal harvest time.
       Insufficient bale density or loose bales is one of the most common problems. This is usually related to uneven feeding, overly dry or wet hay, improper hydraulic system pressure settings, or internal leaks. The tractor's travel speed should be checked and adjusted to ensure uniform feeding; the hay moisture content should be verified to be within the appropriate range; the hydraulic system pressure gauge should be checked, and the pump and valves should be listened for abnormal noises to identify and eliminate leaks.
       Knotter malfunction is one of the main causes of downtime. Symptoms include inability to form knots, broken ropes, or loose knots. First, check if the quality and specifications of the baling rope are compatible with the machine and if the rope threading path is correct. Then, clean the inside of the knotter, checking key components such as the knotting nozzle, knotting needle, and rope clamp for wear, deformation, or jamming, and lubricate or replace them. Sometimes, adjusting the relative position or timing of the knotter and compression chamber can also solve the problem. If a machine fails to start or moves slowly and weakly, it's often related to the power and hydraulic systems. Check if the tractor's PTO speed is sufficient, and whether the power take-off shaft and steering knuckle are damaged. Check if the hydraulic oil level in the tank is sufficient, if the hydraulic oil filter is clogged, and if there are any air leaks in the inlet pipe. If only one action is weak, try operating other hydraulic functions. If all are weak, the problem may be with the pump or the main relief valve. If only a single action has a problem, the corresponding cylinder seal may be damaged or the control valve may be stuck.

When facing a fault, remain calm and follow the principle of troubleshooting from the outside in and from the simple to the complex. Safety is always the top priority; always stop the machine, turn off the engine, and release the hydraulic pressure before any repairs. For complex electrical or hydraulic problems, contacting a professional repair technician is the safest option.
