Product Overview: The Commercial Step Up for 100\u2013500 Acre Dry-Bean Farms<\/h2>\n

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 \u2014 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<\/strong> 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.<\/p>\n

Positioning within our kidney bean harvester series<\/a>, 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\u201388 kW power range aligns with the 90\u2013120 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.<\/p>\n

\"4BYH-2.6<\/p>\n

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 \u2014 both models carry identical specs.<\/p>\n

<\/p>\n

Sp\u00e9cifications techniques<\/h2>\n

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.<\/p>\n

Working Principle: Four Shares, One Windrow<\/h2>\n

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.<\/p>\n

\"4BYH-2.6<\/p>\n

Parallel Share-Point Soil Entry<\/h3>\n

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 \u2014 there is no row-to-row staggering or sequential engagement that would cause uneven pulling tension across the frame.<\/p>\n

Spring-Tine Lift Across Four Rows<\/h3>\n

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.<\/p>\n

Transverse Rolling-Cage Conveyor<\/h3>\n

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 \u2014 the optimal width for a standard combine pickup header to harvest cleanly in one pass.<\/p>\n

Rear Windrow Placement<\/h3>\n

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 \u2014 typically 20 to 30 feet \u2014 to harvest three or more merged windrows per pass, depending on crop density and field conditions.<\/p>\n

<\/p>\n

Four Advantages Built Into the 4-Row Design<\/h2>\n
\n
\n
\ud83d\udcc8 Double the Throughput of a 2-Row<\/div>\n

At 1.56 to 2.6 ha\/h, the 4BYH-2.6 covers two to four times the daily acreage of hand-pulling crews and roughly twice the productivity of a 2-row puller \u2014 all with a single operator. For a 300-acre pinto bean operation, that translates to finishing the pulling phase in 115 to 192 hours at the machine’s rated range, comfortably inside a 10-day weather window.<\/p>\n<\/div>\n

\n
\ud83c\udf31 Under 5% Pod-Shatter Loss<\/div>\n

The spring-tine tine-spacing geometry is calibrated to flex before it shears. At the recommended 6\u201310 km\/h operating speed, the flex-and-recover cycle keeps impact force on each pod below the shattering threshold for pinto, navy, kidney, and black bean varieties. Operators who have transitioned from rigid-finger pullers consistently report shatter losses dropping below 5 percent of total yield.<\/p>\n<\/div>\n

\n
\ud83d\ude9c Matches Your Existing 90\u2013120 HP Tractor<\/div>\n

The 66\u201388 kW power band covers the most common mid-range row-crop tractors used on American dry-bean farms: John Deere 6110R, Case IH Maxxum 110, New Holland T5 Series, Massey Ferguson 5700S, and Kubota M7-132. No tractor upgrade needed \u2014 the machine is built around what’s already sitting in your equipment shed.<\/p>\n<\/div>\n

\n
\ud83d\udd17 Clean Single-Windrow Output<\/div>\n

The transverse rolling-cage conveyor merges four individual row lifts into a single 0.9\u20131.3 m windrow. This means your combine pickup can harvest in fewer passes per field, reducing soil compaction and fuel cost during the final harvest stage. It also simplifies swath planning: one puller pass equals one combine pass on your final field map.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Application Scenarios: U.S. Commercial Dry-Bean Production<\/h2>\n

Michigan Thumb Pinto Bean Belt<\/h3>\n

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 \u2014 cool September nights and early October rains can close the window in under a week \u2014 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.<\/p>\n

Red River Valley Navy Bean Farms<\/h3>\n

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.<\/p>\n

\"4BYH-2.6<\/p>\n

Idaho Garbanzo and Chickpea Harvest<\/h3>\n

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.<\/p>\n

Saginaw Valley Black Bean Production<\/h3>\n

Michigan’s Saginaw Valley grows black beans on heavier, more moisture-retentive soils than the Thumb region, and the later harvest dates \u2014 often late September through early October \u2014 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.<\/p>\n

<\/p>\n

Crop-Pod Care: How Spring-Tine Geometry Keeps Shatter Below 5%<\/h2>\n

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.<\/p>\n

First, tine spacing is set at 65 mm center-to-center \u2014 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.<\/p>\n

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 \u2014 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.<\/p>\n

<\/p>\n

4BYH-2.6 Rear-Pull vs 4BYQ-2.6 Front-Mount: Which Configuration Fits Your Operation?<\/h2>\n

The 4BYH-2.6 (rear-pull) and the 4BYQ-2.6 (front-mount, push-type) carry identical mechanical specs \u2014 same spring-tine design, same 2.6 m working width, same 66\u201388 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.<\/p>\n

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.<\/p>\n

Maintenance Schedule and Wear Parts<\/h2>\n

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

Completing the Harvest Chain: Drivetrain and Post-Pull Logistics<\/h2>\n
\"right-angle<\/div>\n

PTO Driveline Integrity<\/h3>\n

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<\/a> 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.<\/p>\n

Post-Pull Windrow Management<\/h3>\n

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. Contact the U.S. team for a no-obligation harvest planning review at any point before or during the season.<\/p>\n
