4BYH-3.25 5-reihige Kidneybohnen-Erntemaschine | 1,95–3,25 ha/h
Der 4BYH-3.25 Kidneybohnen-Pflücker occupies the commercial sweet spot in our lineup. At 5 rows and 3.25 meters, it covers 25% more per pass than the 4-row models without demanding the 180–200 HP that the 6-row flagship requires. For operations running 300 to 800 acres of dry beans on a 140–180 HP tractor fleet, the arithmetic is straightforward: more throughput per tractor-hour, fewer total hours, and a machine that pays for itself in crew cost savings within two seasons.
The 5-Row Sweet Spot: Throughput Math for 300–800 Acre Operations
Consider a 500-acre pinto bean stand. A 4-row machine at peak output (6.4 ac/h) needs 78 hours. The 4BYH-3.25 at 8.0 ac/h finishes in 63 hours — 15 hours recovered, which in the Red River Valley's narrow September weather window can mean the difference between completing harvest before the first hard rain and finishing after it. Now factor in that you are using the same tractor and the same operator. The incremental cost of the 5-row over a 4-row is recovered in season one from the value of that 15-hour buffer alone, before counting any labor premium for overtime harvesting under time pressure.
Der kidney bean puller lineup at foragebaler.com is organized around this kind of operational math — the right row count for the right fleet, not the largest machine that will technically attach to a tractor.
Technische Spezifikationen
The 4BYH-3.25 accepts Category II (28 mm pin) or Category III (36 mm pin) lower links via a removable adapter bushing. At 1,540 kg mass, your tractor's rear hitch must be rated for a minimum of 2,000 kg at the hitch ball.

Pod Shatter Science: The Engineering Behind ≤4% Loss on 5-Row Scale
Pod shatter at harvest is not random. It is a function of three variables: impact force, rate of force application, and pod-wall tensile strength at the moment of contact. The 4BYH-3.25's spring-tine geometry addresses all three simultaneously — understanding the engineering helps operators set ground speed correctly to stay inside the shatter-safe zone across different soil conditions and crop varieties.
Tine Spacing: 65 mm Center-to-Center
Wide enough that pod clusters pass between tines without being pinched — narrow enough to lift even small-diameter vine sections. The spacing is not arbitrary: it was derived from the abscission zone geometry of pinto and navy varieties, the two most shatter-sensitive beans grown at commercial scale in the U.S. Midwest.
Wire Diameter and Flex Angle: 8–12° Under Normal Load
Tine wire diameter and heat treatment hardness are calibrated to produce 8–12 degrees of deflection under normal root resistance. This flex absorbs the energy that would otherwise transmit as a sharp load spike into the pod wall at the abscission zone. A tine that is too stiff transmits the full root-resistance force to the pod; too soft and it fails to lift efficiently.
Ground Speed: The Operator-Controlled Variable
At 6–10 km/h, the tine impact velocity remains below the shatter threshold for all major commercial varieties. Above 10 km/h, the vine bunches at the rolling-cage exit faster than the conveyor can process it, increasing shatter at the exit point. Operating within the rated speed range keeps shatter at 3.2–4.8% — well inside the 5% contract maximum.
Soil Compatibility Guide: Matching the 4BYH-3.25 to Your Ground
Different U.S. dry-bean growing regions present different soil challenges for a 5-row wide-frame puller. The table below maps the most common soil series in the major bean-growing regions to the recommended 4BYH-3.25 operating adjustments.
| Region | Dominant Soil Type | Frame Behavior | Recommended Setting |
|---|---|---|---|
| Michigan Thumb | Sandy loam (Spinks, Ottokee) | Low resistance, minimal flex load | 8–10 km/h, standard depth |
| Red River Valley, ND/MN | Heavy clay (Fargo, Bearden) | High lateral load on outer shares — consider upgrading to 6-row 4BYHD for 1,000+ ac/season | 6–8 km/h; inspect bracket welds at 150 ac |
| Idaho Snake River Plain | Sandy loam to silty loam, furrow-irrigated | Ridge-and-furrow profile; independent share suspension handles contour well | 7–9 km/h; verify depth across ridges before full-field |
| Nebraska Panhandle | Sandy loam to loamy sand | Low abrasion, high speed possible | 8–10 km/h; monitor share tip wear every 50 ac |
| Minnesota / Wisconsin | Loam to clay loam (Nicollet, Webster) | Medium resistance; root clods moderate | 7–9 km/h; clean tine gaps every 30 ac in wet zones |
Who Buys the 4BYH-3.25 and Why
Four distinct operation types consistently choose the 4BYH-3.25 over adjacent models in our lineup. Each makes the same calculation — more throughput than a 4-row, without the fleet investment a 6-row requires.
Commercial Pinto Belt — Red River Valley (300–600 ac)
Operations in Cass and Richland counties, ND, and Wilkin and Clay counties, MN, that grow pinto beans in rotation with corn and soybeans typically run a 140–180 HP row-crop tractor as their primary field unit. The 4BYH-3.25 plugs directly into that fleet. Harvest windows in the Valley close fast — completing 500 acres in 8 to 9 days versus 12 to 14 with a 4-row protects against the early October frost events that can trap unharvested beans.
Michigan Black Bean Contract Operations (400–600 ac)
Saginaw Valley growers under food-grade black bean contracts face strict sample quality limits. The 4BYH-3.25's 5-row rolling-cage output produces a more uniform windrow density than a 4-row machine, which translates to more predictable combine pickup speeds and lower tare at the elevator. Several contract growers report that upgrading from 4-row to 5-row improved their elevator sample scores by reducing density variation across the swath.
Idaho Organic Garbanzo and Adzuki Operations (300–500 ac)
Certified organic dry-bean growers in the Magic Valley need throughput to self-harvest all their organic acreage within the certification harvest window without hiring conventional contract crews. The 4BYH-3.25's 4.8 to 8.0 ac/h output on Idaho's sandy loam typically allows a 400-acre organic garbanzo stand to be pulled in 5 to 7 days — fully within the window without the IP-contamination documentation risk of outside contract equipment.
Custom Bean Contractors — Midwest Multi-Farm Route (500–900 ac/season)
Custom hay and bean contractors in Iowa, Illinois, and Indiana who pull for 10 to 20 client farms per season find the 4BYH-3.25 allows more clients per week than a 4-row machine with equivalent tractor power. The hydraulic folding makes field-to-field moves fast. Several Wisconsin contractors report adding 20 to 30 percent more contracted acres per season after upgrading from 4-row to 5-row without adding a second tractor or operator.
Where the 4BYH-3.25 Sits in the Lineup
The 4BYH-3.25 is the right choice when your fleet peaks at 140–180 HP and your annual bean acres are between 300 and 800. Below that acreage range, the 4BYH-2.6 kidney bean puller provides adequate throughput at a lower machine cost. Above 700–800 acres on 180–200 HP equipment, the 6-row flagship provides additional throughput headroom worth the power investment.
| Spec | 4BYH-3.25 (This Model) | 4BYHD/4BYHS-3.9 | 4BYH-2.6 |
|---|---|---|---|
| Rows | 5 | 6 | 4 |
| Productivity (peak) | 8.0 ac/h | 9.6 ac/h | 6.4 ac/h |
| Tractor HP | 140–180 HP | 180–200 HP | 90–120 HP |
| Machine Mass | 1,540 kg | 1,675–1,780 kg | 1,100 kg |
| Best Acreage Range | 300–800 ac | 500–1,200+ ac | 100–500 ac |
Drivetrain at 140–180 HP: Gearbox Specification Matters
At 103–132 kW input, the 4BYH-3.25 generates 40–60% higher continuous driveline loads than the 4-row models. The internal transfer gearbox handles this through a spiral bevel gear set rated for sustained input torque above 800 Nm with a peak tolerance of 1,600 Nm for the overload events generated by sudden root-mass contact at commercial ground speed. A correctly specified heavy-duty agricultural gearbox prevents the progressive gear-mesh fatigue that shows first as elevated gearbox noise before eventual tooth failure during the most critical harvest hours. The PTO overload clutch is pre-set at 600–650 Nm — higher than the 4-row models — to accommodate greater continuous torque without nuisance slippage while still protecting against spike events.

Häufig gestellte Fragen
Why is the 4BYH-3.25 better than two 4-row machines for a 600-acre operation?
Two 4-row machines require two operators, two tractors, doubled insurance, doubled maintenance, and doubled parts inventory. The 4BYH-3.25 with one 140–180 HP tractor exceeds the throughput of two 90–120 HP tractors running 4-row machines simultaneously — at roughly 55–60% of the total operating cost. The cross-over point where a single 5-row becomes more cost-effective than two 4-rows is typically around 200 acres per season.
Does the 4BYH-3.25 require a Category III hitch, or does Category II work?
Either Category II (28 mm pin) or Category III (36 mm pin) via a removable adapter bushing supplied with the machine. At 1,540 kg, a Category II hitch must be rated for at least 2,000 kg at the ball. Most 140–180 HP tractors rate Category II at 4,000–7,000 kg. Category III provides additional rigidity in heavy clay where lateral frame loads are highest.
How many spring tines does the 4BYH-3.25 carry?
300 tines — 60 tines per row across all five rows. Each tine is bolted individually via a 2-bolt clip and can be replaced without disturbing adjacent tines. A full 300-tine spare set plus two spare share points ship with every new machine at no additional charge. Replacement packs of 60 (one row) or 300 (full set) available from the U.S. warehouse with same-day dispatch.
Does the 4BYH-3.25 handle 60 cm row spacing as well as standard 65 cm?
Share positions adjust ±40 mm laterally per share for the 60–70 cm range. Row spacing outside that range requires factory consultation before ordering to confirm that modified share positioning doesn't create tine-assembly interference on the wider 3.25 m frame.
How is the windrow width from the 5-row conveyor, and does it work with my combine header?
The rolling-cage produces a 1.0–1.5 m windrow. Most commercial combine bean pickup headers (10–20 ft) can harvest two adjacent 4BYH-3.25 windrows per combine pass after a ground-driven consolidation rake run — reducing combine field passes by roughly 40% versus harvesting individual windrows.
Growers Who Made the Switch to 5-Row
"620 acres of pinto in the Red River Valley on clay loam — the 4BYH-3.25 finished in 9 days. Previous year with a 4-row it took 13. The weather window we had was 11 days. The extra throughput literally saved the crop margin on that field. John Deere 6145R handled the tow without any issues. Shatter at 3.6% on the elevator sample."
Keith Halverson — Cass County, ND (mid 2025)
"480 acres black beans under processing contract. The 5-row windrow density is more uniform than the 4-row we replaced — the combine operator noted it immediately. Our sample tare was the cleanest in the six years of the contract. Case IH Maxxum 150 pairs perfectly."
Carol Schoenherr — Bay County, MI (early 2025)
"550 acres of pinto in Nebraska Panhandle. One operator, one New Holland T6.180, replaced two aging 2-row setups. Labor savings in the first season alone more than offset the machine cost. Arrived assembled and was running inside a few hours of delivery."
Wayne Christoffersen — Scotts Bluff County, NE (late 2024)
"400 acres garbanzo and 180 acres navy beans in the Magic Valley furrow-irrigated ground. Independent share suspension tracked the ridges and furrows consistently. Four stars only because the machine is heavy enough that steep terrace grades need careful speed management. On flat and gentle slopes: excellent."
Thomas Park — Twin Falls County, ID (mid 2025)
"530 acres navy beans in central Minnesota across sandy loam and clay transition soils. The 4BYH-3.25 performed uniformly across both soil types with only a minor depth adjustment between fields. Massey Ferguson 6718S pairs well. The pre-purchase call to verify tractor specs was a genuinely helpful service — caught a front-ballast configuration issue before delivery."
Jennifer Stordahl — Otter Tail County, MN (early 2025)
