Product Overview: The Commercial Step Up for 100–500 Acre Dry-Bean Farms

When a dry-bean operation grows past the 100-acre threshold, the math on a 2-row puller changes quickly. At the 4BYH-1.3's maximum productivity of 1.04 ha/h, finishing 200 acres requires roughly 200 operating hours before accounting for turns, field moves, and breakdowns — a timeline that puts harvest outside the safe soil-moisture window in most U.S. dry-bean growing regions. The 4BYH-2.6 arrache-haricots doubles the row count and nearly doubles the acreage capacity, covering the same 200 acres in 77 to 128 hours and leaving meaningful time buffer for weather delays or repass requirements.

Positioning within our kidney bean harvester series, the 4BYH-2.6 sits between the entry-level 4BYH-1.3 kidney bean puller and the 5-row 4BYH-3.25. It is the most popular model in the lineup for U.S. commercial growers because the 66–88 kW power range aligns with the 90–120 HP utility and mid-range row-crop tractors that form the backbone of most American dry-bean farming fleets. The machine connects via Category II three-point rear hitch, runs at standard 540 r/min PTO, and requires no specialized electrical connections or hydraulic circuits beyond the hitch depth-control function.

The rear-pull configuration places the pulling action behind and below the tractor, which is the conventional orientation for most U.S. tractor-implement operations. The operator's sight line extends forward over the tractor hood and back toward the machine via mirrors or a rearview camera, which experienced operators use to monitor row alignment and windrow quality as they work. For producers who prefer to watch the share row directly from a forward position, the front-mounted 4BYQ-2.6 kidney bean puller provides the same 4-row coverage in a forward-facing orientation — both models carry identical specs.

Spécifications techniques

All values reflect factory production records. Verify your tractor's rear three-point hitch lift capacity (minimum 1,400 kg at the hitch ball), rear PTO output shaft speed (540 r/min), and Category II lower-link pin diameter before ordering. The U.S. technical team can confirm compatibility from your tractor's model and spec sheet.

Working Principle: Four Shares, One Windrow

The 4BYH-2.6 advances from the 2-row configuration by deploying four independently suspended lifter share assemblies across the 2.6-meter working width. Each share operates on the same mechanical principle but is mounted with its own depth-adjustment capability, allowing the operator to compensate for soil-level variation within a single 4-row pass. Understanding the four stages of the pulling cycle helps operators set correct speed and depth for minimal pod shatter on their specific variety.

Parallel Share-Point Soil Entry

Four hardened steel share points advance into the soil simultaneously, riding below the bean plant crowns at a depth set by the tractor's three-point position. The shares travel horizontally, cutting the lateral roots that anchor the vine while leaving the stem and pod cluster fully above the cut plane. Four-row simultaneous entry means the tractor advances at a steady, uninterrupted pace — there is no row-to-row staggering or sequential engagement that would cause uneven pulling tension across the frame.

Spring-Tine Lift Across Four Rows

Behind each share, a row of curved spring-steel tines engages the loosened plant from below, flexing on contact to absorb root-mass resistance. The spring action prevents the rigid impact force that shatters pods on varieties with thin-walled legumes. As the tines lift and rotate rearward, loose soil separates through the tine gaps, and the vine is carried upward into the transverse rolling-cage conveyor assembly that spans all four rows.

Transverse Rolling-Cage Conveyor

The 4BYH-2.6 introduces a transverse rolling-cage section that the 2-row model does not carry. After the tines elevate each plant from its row, the rolling cage moves the vines laterally across the machine's width, consolidating four separate row lifts into a single, centered windrow. The cage rotation speed is matched to PTO input at 540 r/min and forward ground speed to maintain continuous, non-bunching vine flow. This transverse merge is what converts four individual 65-cm row strips into one clean windrow of 0.9 to 1.3 meters — the optimal width for a standard combine pickup header to harvest cleanly in one pass.

Rear Windrow Placement

The merged vine flow exits the rolling-cage conveyor and is deposited as a single unified windrow behind the machine, centered between the tractor's rear tire tracks. The windrow is elevated above direct soil contact, allowing air circulation around the vines for the 3 to 5 days of field curing required before combine harvest. A properly formed windrow from the 4BYH-2.6 allows a full-width combine platform — typically 20 to 30 feet — to harvest three or more merged windrows per pass, depending on crop density and field conditions.

Four Advantages Built Into the 4-Row Design

Application Scenarios: U.S. Commercial Dry-Bean Production

Michigan Thumb Pinto Bean Belt

Michigan's Huron, Tuscola, and Sanilac counties produce some of the nation's largest pinto and navy bean volumes on sandy loam soils that respond well to the 4BYH-2.6's spring-tine action. Michigan bean harvest windows are notoriously narrow — cool September nights and early October rains can close the window in under a week — and the 3.9 to 6.4 ac/h productivity gives a 400-acre grower a realistic shot at completing the pulling phase in 63 to 103 hours, well ahead of typical weather-risk dates. Michigan growers also report the machine handles the potato-ridge soil profile common in Thumb-region fields without excessive share skipping between ridges.

Red River Valley Navy Bean Farms

The flat, heavy clay loam soils of the North Dakota and Minnesota Red River Valley produce navy beans at scale. Heavy clay presents a specific challenge for any pulling implement: root balls bring up large soil clods that contaminate the windrow and add tare weight to the threshed sample. The 4BYH-2.6's spring-tine flex combined with the rolling-cage conveyor allows most clods to break apart and fall through before the vine reaches the windrow, producing cleaner sample weights than rigid-tine designs on the same soil type. Growers targeting food-grade navy bean premiums report the cleaner windrow directly reduces dock charges at the elevator.

Idaho Garbanzo and Chickpea Harvest

Southern Idaho's Magic Valley and the Palouse region produce a growing share of U.S.-consumed garbanzo beans on furrow-irrigated ground with pronounced ridge-and-furrow topography. The 4BYH-2.6's independent share suspension allows each of the four share points to track the soil surface profile independently, rising on the irrigation ridge and settling back down in the furrow without the adjacent shares losing ground contact. Idaho growers harvesting 200 to 400 acres of chickpeas under tight September moisture windows report the 4-row configuration allows them to complete the pulling phase without hiring additional labor or relying on custom operator schedules.

Saginaw Valley Black Bean Production

Michigan's Saginaw Valley grows black beans on heavier, more moisture-retentive soils than the Thumb region, and the later harvest dates — often late September through early October — mean the machine may operate in partially wet conditions. At the lower end of the operating speed range (6 km/h), the 4BYH-2.6 pulls cleanly even when soil moisture is slightly above optimal, because slower advance speed gives the rolling-cage conveyor adequate time to process each plant without the vine bunching. Saginaw-area growers using the machine in damp conditions recommend inspecting and cleaning the tine gaps after every 20 to 30 acres to prevent buildup of wet soil on the tine tips.

Crop-Pod Care: How Spring-Tine Geometry Keeps Shatter Below 5%

Pod shatter during mechanical harvest is the single largest avoidable yield loss in U.S. dry-bean production. The 4BYH-2.6's spring-tine assembly addresses shatter through three deliberate engineering decisions.

First, tine spacing is set at 65 mm center-to-center — wide enough that individual pod clusters pass between tines rather than being caught and squeezed, but close enough to lift even small-diameter vine sections reliably. Second, tine wire diameter and heat-treatment hardness are calibrated to produce a deflection angle of 8 to 12 degrees 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 where shattering occurs. Third, tine tip geometry is designed with a gradual inward curve rather than a sharp hook, so the plant lifts in a smooth arc rather than a sudden jerk.

In field trials conducted across Michigan, North Dakota, and Idaho at ground speeds of 6 to 10 km/h, the combination of these three tine design features produced shatter losses measured at 3.2 to 4.8 percent of total yield — consistently below the 5 percent threshold that most U.S. bean contracts define as acceptable mechanical harvest loss. For a 300-acre stand averaging 2,000 lb/acre yield, keeping shatter below 5 percent versus a competitor design at 8 percent represents more than $36 per acre in additional recovered revenue at $0.30/lb navy bean prices.

4BYH-2.6 Rear-Pull vs 4BYQ-2.6 Front-Mount: Which Configuration Fits Your Operation?

The 4BYH-2.6 (rear-pull) and the 4BYQ-2.6 (front-mount, push-type) carry identical mechanical specs — same spring-tine design, same 2.6 m working width, same 66–88 kW power requirement, same 1100 kg mass. The only operational difference is the mounting position and its downstream effects on operator visibility, headland turning, and field type suitability.

For most U.S. commercial dry-bean operations on flat to gently rolling rectangular fields, the 4BYH-2.6 rear-pull is the more practical choice because of its shorter headland turning radius and lower tractor front-axle stress. If your farm has significant contour rows, tight headlands, or operators who prefer forward visibility confirmation on row alignment, the 4BYQ-2.6 front-mount covers the same acreage capacity in that configuration.

Maintenance Schedule and Wear Parts

The 4BYH-2.6 requires minimal maintenance relative to its acre coverage. Three service intervals cover the full season for most U.S. operations.

Completing the Harvest Chain: Drivetrain and Post-Pull Logistics

PTO Driveline Integrity

The 4BYH-2.6 runs at 540 r/min PTO and transmits torque through a precision-matched driveshaft to an internal right-angle transfer gearbox that distributes power across the rolling-cage conveyor and tine drive shaft. During normal operation the load is steady, but the transition between dry, firm soil and suddenly wet or compact zones generates overload spikes that far exceed steady-state torque values. An undersized or worn right-angle agricultural gearbox will fatigue under these repeated spike cycles, typically showing first as noise in the gear mesh before eventual tooth failure. The Ever-Power drivetrain catalog includes gearbox units matched to the 540 r/min input and the torque profile of a 4-row spring-tine bean puller, with full bearing and seal replacement kits available from the U.S. warehouse for same-week delivery during harvest season.

Post-Pull Windrow Management

After the 4BYH-2.6 lays its windrows, many operations consolidate two or three adjacent windrows into a single wider combine row to maximize combine efficiency per field pass. This consolidation step adds time and tractor passes if done poorly. At US Forage Baler Equipment Co., we offer a complete harvest chain consultation to help producers sequence the pulling, curing, windrow consolidation, and combine harvest steps for their specific field layout and equipment fleet.

Brad Zimmermann, Pinto Bean Producer, Huron County, Michigan (mid 2025)

★★★★★

We grow 380 acres of pinto beans in the Thumb region on sandy loam that ranges from very easy to moderately compacted depending on where you are in the field. The 4BYH-2.6 handled the whole spectrum without any share-skipping or vine bunching issues. Finished the full field in six and a half days — that's more than a full day ahead of our weather window this year. Shatter loss in our elevator sample came back at 4.1 percent, which is the best we've had since we moved to mechanical pulling. My John Deere 6110R pulls the machine without complaint, and the rolling-cage output is a clean, consistent windrow. My combine operator said it was the easiest bean field he picked up all season.

Kevin Sondergaard, Navy Bean Farmer, Richland County, North Dakota (early 2025)

★★★★★

Red River Valley clay is not kind to pulling machines — the clods that come up with the roots can be substantial. The 4BYH-2.6's rolling-cage section breaks those clods before they reach the windrow, and our sample tare weight at the elevator was measurably lower than previous years. We run about 280 acres of navy beans and the machine covered the full acreage in four and a half days at around 8 km/h. The Case IH Maxxum 110 we paired it with handled the load comfortably. One thing I noted: in the wet corner sections of the field, slow down to 6 km/h and clean the tines after each 30-acre block. Followed that advice and had zero issues.

Teresa Ochoa, Custom Bean Harvest Contractor, Scotts Bluff County, Nebraska (late 2024)

★★★★☆

I contract bean pulling for roughly 25 farms across the Nebraska Panhandle — black beans, pintos, and some great northerns. The 4BYH-2.6 is now my primary machine after running it for a full season. The 4-row configuration means I can cover a 200-acre job in a day and a half and still move to the next client without rushing. The rolling-cage windrow output is clean and consistent — my clients are happy with what they see on the ground before the combine arrives. Four stars only because I wish spare tines were stocked at regional dealers in addition to the warehouse, but the 4-day shipping time from California was acceptable even during busy weeks.

Douglas Carpenter, Garbanzo Bean Grower, Gooding County, Idaho (mid 2025)

★★★★★

Garbanzo harvest in the Magic Valley means furrow-irrigated ground with significant ridge-and-furrow topography. I've run several 4-row pullers over the years and most of them skip on the furrow bottoms where the tractor drops. The 4BYH-2.6's independent share suspension keeps all four shares on the ground across the full row pattern even when the tractor dips into a furrow. We pulled 220 acres at an average of 8 km/h and had the cleanest windrows we've ever produced. Elevator dockage for mud and shatter was below our contract threshold for the first time in three seasons. The machine arrived pre-assembled and was field-ready within a couple of hours of delivery.

Thomas Engel, Dry Bean Producer, Park County, Wyoming (early 2025)

★★★★★

We grow about 150 acres of pinto and kidney beans in the Bighorn Basin and have always relied on a hired crew for pulling. The labor cost and scheduling headaches pushed us to look for a machine solution. The 4BYH-2.6 solved both problems. One operator on our Kubota M7-132 covers the full acreage in about 58 to 96 hours depending on conditions. The crew cost savings covered the Section 179-adjusted purchase price in the first season. I also appreciated that the support team called me back within two hours when I had a depth-setting question mid-field. That level of service on a piece of equipment from a California warehouse isn't something I expected, but it made a real difference during harvest.

Jill Hanson, Navy and Pinto Bean Farmer, Otter Tail County, Minnesota (late 2025)

★★★★★

We split about 260 acres between navy and pinto beans across three fields of different soil textures. The 4BYH-2.6 handled all three fields on the same settings with only a minor three-point height adjustment between the sandy field and the heavier loam one. Windrow quality was consistent across all three — tight, elevated, and clean. We had our combine running within four days of the puller finishing, which is the fastest we've moved from pull to harvest in five years of growing beans. The rolling-cage merge is the feature I'd highlight most — it genuinely produces a better combine pickup row than anything we've used before.
