Wheat Harvester 2021 Model offers high operational efficiency and superior performance. Here is a detailed introduction to the Foton Wheat Harvester 2021 Model: 1. High Operational Efficiency: Equipped with a 700mm widened bridge for smoother feeding, suitable for harvesting high-yield crops. The extended composite drum features low power consumption and strong threshing and separation capabilities. The patented upper air intake radiator dust cover reduces cleaning frequency and saves maintenance time. 2. Superior Performance: The 840mm widened cleaning chamber provides strong cleaning ability and high grain cleanliness. The double-layer reverse vibration sieve improves grain cleanliness by over 20% compared to traditional models.

I operated the 2021 wheat harvester throughout the entire harvesting season, and its overall efficiency is indeed impressive. The 5 kg/s feeding capacity is more than sufficient for wheat fields in the North China Plain. The hydraulic system responds sensitively during turns, preventing any wheat stalk crushing. The grain tank elevator is 15% wider than the older model, reducing unloading time to under 90 seconds. Two points to note: with a 32 cm chassis ground clearance, you must slow down when crossing ditches to avoid scraping the drive shaft; after rainy days, it's best to install an anti-wrapping device to prevent the reel from getting clogged with straw. This model currently has high circulation in the used market—when purchasing, pay special attention to concave sieve wear and hydraulic oil cleanliness.

As a veteran with ten years of experience operating harvesters, what impressed me most about the 2021 model is its fuel consumption control. The Weichai 160-horsepower engine has a rated fuel consumption of 18 liters per hour, and actual full-load operation consumes around 22 liters, saving about 5 liters compared to some imported models. The dual-roller threshing mechanism is well-tuned, keeping grain breakage rates below 1.2%. However, the cabin insulation is average, so you'll need plenty of ice water for midday operations. If purchasing, I recommend opting for the straw shredder attachment—with strict environmental regulations nowadays, direct field return is both convenient and compliant. Remember to grease the steering linkage three times per season, otherwise the steering play will gradually increase.

Last year, we purchased six units of this machine for the cooperative, and the harvesting data speaks volumes: the mean time between failures is 62 hours, with a maximum daily workload of 180 acres. The key advantage is the easy availability of spare parts, as most agricultural machinery shops in the county have them in stock. The driver's seat comes with vibration damping and ventilation, allowing for 10 hours of continuous operation without back pain. One thing to note is that the grain bin sensor tends to get clogged with wheat awns, so it's necessary to use an air gun to clean it after each workday. The chain case has slightly weaker sealing, so it's recommended to add a rubber strip for dust prevention. Compared to the newer models currently available, this generation may have a smaller screen, but its mechanical structure is more robust.

Harvesting efficiency can be evaluated from three aspects: The operating speed of 8 acres per hour isn't the fastest, but the 0.8% header loss rate stands out. The hydraulic system's maximum pressure of 18MPa is sufficient for lodged wheat, though efficiency drops when oil temperature exceeds 85°C. After modifying the cooling fan speed, I managed to reduce summer operating temperatures by 6°C. The adjustable wheelbase design is highly practical—narrowing from 2.3m to 1.9m allows access to small plots. When purchasing, don't forget to inspect the ball joint pin on the cutterbar linkage, as this part wears quickly. The threshing concave clearance should be adjusted according to wheat moisture: 2 finger-widths for dry wheat, at least 3.5 for damp wheat.

Actual tests comparing the 2021 model with the latest version revealed significant cost advantages for this generation. The average price of engine maintenance parts is 40% cheaper than the new model, and two V-belts cost only 120 yuan. The properly spaced reel teeth design on the header rarely gets tangled with grass. The biggest surprise is the 2.5 cubic meter grain tank capacity, which is particularly suitable for slope operations - it won't spill grain even at a 35-degree tilt. It's recommended to install a grain tank baffle to prevent grain loss. Remember to replace the oil seal on the steering axle every two years - there have been several cases of steering pump failure due to sludge buildup. Overall, this machine is like an old ox - you can work it hard for five years without major repairs.
