By Li Guangming, tractor operator with 14 years experience. Silage team lead for the Liu family farm in Hebei Province. This is a real account of one day in the 2026 autumn silage season — no polish, just the field truth.
Location: Daming County, Handan, Hebei, China | Crop: Corn silage, Pioneer 1543 | Field: 38 acres across 3 plots | Machine: FOYA 9ZQ-1800 tractor-mounted silage harvester
5:30 AM — Pre-shift inspection
Alarm went off at 5:15. By 5:30 I was already at the shed with my headlamp on. First thing — check the silage harvester. I grabbed the grease gun and went over every fitting on the PTO shaft and cutterhead bearings. There's nothing worse than a failed bearing at 10 AM when you're three rows deep and the chopper is screaming at full throttle.
Oil level in the gearbox — good. Blade condition — the 12 chopping knives were still sharp from yesterday, but I flipped the four end blades anyway. That's the rule: any blade that's touched the ground gets flipped before a new day. Belt tension on the feed rollers — I tightened the adjustable pulley by half a turn. Loose belts rob you of throughput all day long. At exactly 6:00, I climbed into the tractor cab. Engine start. Everything sounded tight. We rolled out at 6:10 — ten minutes behind goal but ahead of last year's start time.
6:45 AM — First round
Sun was barely up over the field edge. Moisture reading on the first three stalks: 68%, 67%, 69%. Perfect. Target window for corn silage is 65-70%. Any drier and you lose fermentation quality; any wetter and you get seepage in the bunker. The field foreman gave the nod. I dropped the header to 6 inches above ground, engaged the PTO at 540 rpm, and eased the tractor forward. The FOYA 9ZQ-2000 grabbed the first row of corn like it was hungry. Stalks fed in clean — the feed roller gap was set at 3mm last night and it was still dialed right. Chopped length was coming out around 18mm, which is what the nutritionist specified for this herd. Two full passes across the 200-meter rows and the chopper bin was ready. We had two trucks running relay — one loads while the other runs to the pit.
8:30 AM — First load to the pit
The truck came back from the bunker. The pit crew reported the density was good — they were getting compaction readings in the upper range. A good sign. We kept going. Third pass, fourth pass. At row 12 I heard a slight pitch change from the cutterhead — that high-frequency whine that says something's not right. I killed the PTO immediately and hopped out. Checked the blades. Sure enough, a small stone had nicked the edge of blade #7. Nothing catastrophic, but the edge was slightly rolled. I swapped it with the spare set I always carry — 20 minutes downtime including finding the right socket in my toolbox. The foreman was already on the radio asking what the delay was. I told him: "Better 20 minutes now than a cracked blade at noon." He grunted and told the truck driver to take a breather.
11:15 AM — Heat check and moisture shift
By late morning the temperature had climbed to 34°C. The corn was noticeably drier. I stopped and took another moisture sample: 63%. Still in range but trending down. The field foreman agreed — we would push through the remaining six rows of this plot and then switch to the second field, which was planted two weeks later and would still be in the 67-70% sweet spot. This kind of mid-day adjustment is what separates experienced crews from rookies. If you just plow through regardless of moisture, you end up with inconsistent silage quality across your feed inventory. I've seen it happen: one batch of silage at 62% moisture and the next at 72% means the nutritionist has to rebalance the TMR twice a week. That costs the farmer real money.
12:30 PM — Lunch and a chat about the chaff cutter
We broke for lunch at 12:30. Rice, braised pork, cold cucumber salad — standard field lunch, eaten squatting under a tarp because the sun was brutal. The new kid asked me about the chaff cutter sitting on the edge of the yard. He wanted to know why we use the silage harvester for the field but keep a stationary chaff cutter for processing straw in the off-season. I explained: the silage harvester is for fresh forage straight from the field — it cuts, chops and loads in one pass. The stationary chaff cutter is for dry straw and hay that's already been baled. Both machines use the same basic principle (rotary drum with blades), but they're optimized for different moisture levels and throughput. A good farm needs both. He nodded and went back to his rice.
2:00 PM — Second field, second wind
Field two was a 16-acre plot planted with Pioneer 1543 on June 7 — exactly two weeks later than field one. Moisture at first check: 69%. Perfect. The stalks here were slightly thicker — higher lignin content from the later planting — so I increased the feed roller pressure by one notch and reduced ground speed from 4.5 km/h to 4.0 km/h. The FOYA's cutterhead handled it without complaint. This is where experience pays off: you learn to read the machine by sound. When the pitch stays steady, you're in the zone. When it climbs, you're overloading. When it drops, you're going too slow and losing productivity. A good operator makes these adjustments without thinking. By 4 PM we had finished field two and loaded 14 truckloads — approximately 110 tons of chopped silage.
4:45 PM — Shed work: maintenance and round baler handover
Back at the shed, I power-washed the silage harvester from top to bottom. Silage juice is acidic — if you leave it on the machine overnight, it starts eating through paint and metal. Twenty minutes with the pressure washer, then a quick blow-dry with compressed air on the electrical connectors and bearing seals.
The farm manager came by to ask about scheduling the round baler for the following week — they had 12 acres of alfalfa that needed baling after the silage run was done. I checked the baler's knotters and twine tension and told him it was good to go. The same tractor that pulls the silage harvester can hitch to the round baler with a quick coupler swap — that's one reason tractor-mounted implements are so popular on mid-size Chinese farms. One 100-hp tractor can do silage harvest, hay baling, and even power a PTO-driven feed mixer through the winter.
6:30 PM — Day's numbers
Sitting in the shed office, I tallied the day:
— Acres harvested: 38 (field one: 22, field two: 16)
— Truckloads: 22
— Estimated tonnage: 176 tons (at approximately 8 tons per load)
— Average moisture: 66.5%
— Downtime: 20 minutes (blade swap)
— Fuel used: 68 liters (diesel)
— Diesel cost per acre: roughly ¥42 (about $5.80 USD)
The farm manager was happy. He said the yield was 10% above last year's first cut, thanks to better rainfall management. We shook hands. Tomorrow we start on field three — a 12-acre plot that was planted a bit late, so the moisture might still be over 70%. I'll set the feed roller gap wider and increase the theoretical chop length to 22mm to compensate. Every field is different. That's what keeps this job interesting.
Final thought for farmers reading this: The machine matters — a good silage harvester with sharp blades, correct belt tension, and the right feed roller setup will do 90% of the work for you. But the other 10% is the operator reading the field, feeling the machine, and making adjustments on the fly. If you're buying your first silage harvester, invest in a machine with easy blade access, a reliable gearbox, and a dealer who stocks spare parts. The FOYA 9ZQ series checks all those boxes. And don't forget a good chaff cutter for the winter months — you'll be glad you have it when the silage pit is closed and the straw needs processing.
