Product Overview & Value Proposition

What is the EP-4BYH-1.3 Rear-Mounted Bean Harvester?

The EP-4BYH-1.3 is an industrial-grade, 2-row harvesting implement designed specifically for dry edible beans (such as pinto, black, navy, and kidney beans) as well as soybeans and other fragile legumes. Direct combining of dry beans often results in massive shatter losses at the header. To prevent this, beans must be gently undercut, pulled, and laid into aerated windrows to dry down evenly before threshing. The EP-4BYH-1.3 accomplishes this flawlessly. Its spring tine rotor lifts the vines while allowing dirt and clods to fall through, placing a clean, fluffy windrow behind the tractor.

By manufacturing our equipment in-house with robust materials suited for harsh environments, we provide global procurement managers with a machine that vastly outperforms fragile imported brands. You gain access to rugged, field-tested technology that lowers your capital expenditure while maximizing your tons-per-hectare yield.

The Agronomic Science: Why Spring-Tine Bean Pulling Maximizes Yield

Harvesting dry beans presents a unique agronomic challenge. The pods become highly brittle as they dry, and the vines often tangle close to the soil surface.

• Shatter Loss Mitigation: Traditional cutter bars can strike the brittle pods, causing them to shatter and drop seeds into the dirt—resulting in yield losses of up to 20 percent. The EP-4BYH-1.3 utilizes a rotating spring tine mechanism. This system lifts the plant from below the pod canopy, ensuring the kinetic energy is absorbed by the flexible vines rather than the fragile pods.

• Dirt and Stone Separation: Bean buyers demand clean crops; dirt clods and stones introduced during harvesting downgrade the crop’s value and can severely damage the internal threshing cylinders of a combine. The lifting action of our spring tines agitates the root system just enough to shake loose heavy soil, ensuring a clean windrow.

• Accelerated Dry-Down: By pulling the beans and placing them in an elevated, fluffy windrow, ambient air can circulate through the crop. This accelerates the curing process, bringing the moisture level down to the ideal 14-16 percent required for safe storage and high-quality threshing.

Material, Metallurgy & Quality Control Standards

As a India manufacturer accustomed to equipment operating in heavy, abrasive soils, we over-engineer the EP-4BYH-1.3 using premium metallurgy to guarantee zero mid-harvest structural failures.

Premium Engineering Materials

• Reinforced Tubular Chassis: The main frame, weighing a solid 600 kg, is constructed from thick-walled carbon steel (Equivalent to ASTM A500 Grade B). This provides the extreme rigidity needed to prevent frame warping when operating in hard-baked clay or rocky soil.

• High-Carbon Spring Tines: The pickup tines are forged from premium 65Mn high-carbon steel. They undergo a precise oil-quench and tempering process to achieve an exact hardness of HRC 45-50. This metallurgy gives the tines the dynamic elasticity to lift heavy vines and strike hidden rocks without permanently bending.

• Heavy-Duty PTO Gearbox: Power from the tractor’s 540 r/min PTO is transferred through a sealed, cast-iron gearbox utilizing precision-cut helical gears. It is continuously bathed in GL-5 gear oil to prevent overheating during 14-hour harvest days.

• Sealed Bearings: The rotor shafts spin on precision-machined hubs fitted with sealed roller bearings, packed with high-temperature lithium grease to ensure frictionless operation in extreme dust.

EVER-POWER Rigorous Quality Workflow

1. Dynamic Rotor Balancing: The entire spring tine rotor assembly is dynamically balanced using laser-guided equipment to eliminate harmful vibrations that could damage the tractor’s PTO shaft or the harvester’s bearings.

2. Robotic Welding: Major 3-point hitch connections are robotically welded for absolute consistency, ensuring the 600 kg implement can be lifted safely thousands of times.

3. Electrostatic Armor Coating: To combat the highly corrosive effects of plant sap and morning dew, the entire steel assembly is sandblasted and coated with an industrial-grade, UV-resistant electrostatic powder finish.

Installation & Setup Guide

Proper setup guarantees that the EP-4BYH-1.3 delivers zero-shatter performance and maintains its 0.65 to 1.04 hm2/h productivity rate.

1. 3-Point Hitch Connection: Carefully reverse the tractor to align the draft links with the lower hitch pins of the harvester. Attach the lower links, followed by the top link. Secure all connections with linchpins.

2. PTO Shaft Installation: Slide the universal PTO shaft onto the tractor’s 540 r/min output spline. Ensure the locking pin clicks into the groove. Fasten the PTO safety chains to a stationary point on both the tractor and the implement.

3. Leveling the Machine: Using the tractor’s top link turnbuckle, adjust the harvester so that the main frame sits perfectly level with the ground when lowered to the working position.

4. Working Depth Calibration: Adjust the gauge wheels (or tractor hydraulics) so the spring tines operate just below the soil surface, engaging the root crown of the bean plant without digging excessively deep into the dirt.

5. Operational Testing: Engage the PTO at a low idle to verify the rotor spins smoothly without binding. Gradually increase engine RPM to achieve the required 540 r/min PTO speed before entering the crop row.

Comprehensive Maintenance & Troubleshooting Guide

While the EP-4BYH-1.3 is built for brutal conditions, routine inspections are required to protect your investment.

Routine Maintenance Schedule

• Daily Checks (Every 10 Operating Hours):

  • Inspect the spring tines for damage or missing pieces. Replace any broken tines immediately using a standard wrench to prevent un-pulled beans.

  • Grease the cross journals (U-joints) on the PTO drive shaft.

  • Check the primary gearbox for any signs of oil seepage.

• Weekly Checks (Every 50 Operating Hours):

  • Check the tension of any internal drive belts or chains transferring power from the gearbox to the rotor. Adjust if slippage is detected.

  • Using high-quality NLGI 2 lithium grease, thoroughly lubricate all rotor bearings and gauge wheel hubs.

  • Verify torque on all structural frame bolts.

• End of Season Storage:

  • Power-wash the entire 600 kg implement to remove corrosive soil, dust, and plant sap.

  • Drain and replace the GL-5 gear oil in the main gearbox.

  • Store the machine in a dry, covered shed, resting on wooden blocks to keep the tines off the damp floor.

Troubleshooting Common Issues

• Issue: The machine is leaving beans un-pulled or skipping plants.

  • Solution: The working depth is too shallow, or the tractor is not aligned with the 1300 mm wheel track. Lower the 3-point hitch slightly and ensure the tractor tires are centered in the furrows.

• Issue: Excessive pod shattering is occurring.

  • Solution: The PTO speed may be too high, or the ground speed is too fast. Ensure the PTO is strictly at 540 r/min and maintain a steady ground speed of 5 to 8 km/h. Also, harvest during early morning hours when pod moisture is slightly higher.

• Issue: Excessive soil is being mixed into the windrow.

  • Solution: The tines are running too deep into the soil. Adjust the top link or gauge wheels to raise the pickup mechanism so it only engages the root crown.
