Features of the AWB-1600 BAR 2 Row Potato Digger for Tractor

1. Heavy-Duty Trailed Frame Construction
The foundation of this tractor potato digger is its massive 1350 kg trailed frame, engineered for exceptional stability while remaining highly responsive to tractor steering commands. Unlike lighter mounted units, the design keeps the machine firmly planted even on uneven ground, allowing operators to maintain straight-line accuracy at working speeds up to 10 km/h. This balanced weight distribution reduces operator fatigue and protects both the equipment and the soil structure during long harvesting days.

2. Reinforced Share Blades for Clean Lifting
Precision-engineered share blades on the AWB-1600 BAR potato digger slice cleanly beneath each row, lifting tubers with minimal soil upheaval and preserving surrounding crop integrity. The reinforced edges resist bending or dulling even after hours of continuous use in compacted fields, delivering consistent depth control that prevents missed potatoes or excessive clods. Growers using this 2 row potato digger report noticeably cleaner extraction compared with older single-row models.

3. Advanced Vibrating Webs System
A series of high-frequency vibrating webs follows immediately behind the share blades, efficiently separating soil, stones, and plant debris while gently conveying potatoes rearward. The adjustable vibration intensity adapts instantly to changing moisture levels, ensuring tubers arrive at the discharge area almost soil-free. This core feature of the PTO potato digger dramatically cuts post-harvest cleaning time and protects delicate skins from abrasion.

4. Dual-Row Processing Capability
The two-row configuration of this potato digger for tractor processes parallel rows simultaneously, effectively doubling daily output without demanding larger tractors or additional passes through the field. Perfect row alignment is maintained by the trailed chassis, so both rows receive identical treatment regardless of slight variations in planting spacing. Commercial operations value this efficiency when time windows for harvest are narrow.

5. On-the-Go Hydraulic Control System
Integrated hydraulic controls on the AWB-1600 BAR allow real-time adjustments to digging depth and web speed directly from the tractor seat. Operators can respond immediately to sudden changes in soil moisture or tuber size without stopping, maintaining optimal performance throughout the day. Only two remote valves are required, making setup straightforward on most standard tractors equipped for PTO-powered implements.

6. Efficient Side-Discharge Mechanism
The signature side-discharge system of the BAR variant neatly deposits potatoes into windrows or straight onto collection conveyors, minimizing manual handling and greatly reducing bruising risk. Potatoes leave the machine in a single, organized line that simplifies pickup by following trailers or sorting crews. This practical layout has become a favorite feature among farmers who previously struggled with center-discharge congestion.

7. Superior Weight Distribution Design
By distributing its 1350 kg mass evenly across support wheels rather than concentrating load at the three-point hitch, this trailed potato digger creates far less soil compaction behind the tractor. Fields stay healthier for subsequent operations, and the machine tracks more predictably on slopes or soft ground. Growers who previously used compact 3 point hitch potato digger models notice the difference in both crop yield and field condition the following season.

Operating Principle of the PTO Potato Digger Machine

• PTO Power Transmission and Drive Shaft Engagement
  Power delivery starts the moment the tractor’s PTO shaft spins at 540 RPM, sending steady torque straight into the AWB-1600 BAR potato digger’s main gearbox. This direct mechanical link activates the primary drive shaft without delay, setting every moving part in motion with smooth, uninterrupted energy. Farmers notice immediately how this consistent 540 RPM input keeps the machine running evenly across uneven ground, eliminating the power fluctuations common in older or less refined PTO potato digger models.
• Share Blades Undercutting and Row Lifting
  As the drive shaft turns, reinforced share blades slice precisely under each potato row, lifting the entire soil strip in one clean motion. The blades work at a controlled depth that loosens the ground just enough to free the tubers while leaving surrounding soil largely undisturbed. This initial lifting action is the heart of the 2 row potato digger’s gentle approach, preventing tuber damage right from the first contact and preparing the crop for the separation stages ahead.
• Oscillating Webs for Soil and Debris Separation
  Material then flows rearward onto the vibrating webs, which oscillate at carefully tuned frequencies to sift away soil, stones, and vine remnants. Potatoes ride along the top surface almost untouched, protected by the web’s gentle movement. The system adjusts automatically to field conditions, ensuring clean separation even when soil moisture changes mid-pass, a feature that sets this tractor potato digger apart from simpler machines.
• Deviner Webs and Optional Kit Refinement
  Following the main webs, deviner webs plus optional Kit A, B, or C configurations further polish the separation process. These secondary webs remove any remaining foliage or small clods before directing the clean tubers toward the side discharge. Each kit can be swapped quickly in the field, giving operators full control to match the exact crop and soil type they face on any given day.
• Hydraulic Real-Time Adjustments During Operation
  Two hydraulic control valves allow the driver to fine-tune web tension, angle, and digging depth instantly from the tractor seat. This real-time modulation adapts the potato digger machine to sudden changes in terrain or moisture without ever stopping forward progress. The continuous-flow design keeps harvest moving at 5–10 km/h, removing the stop-start limitations found in many smaller potato digger harvester units.
• Side Discharge and Final Windrow Formation
  At the final stage, the side-discharge system neatly deposits potatoes into organized windrows or straight onto collection conveyors. The entire flow ends with tubers ready for immediate pickup, free of excessive soil and protected from bruising. This methodical, step-by-step process delivers high throughput while keeping mechanical stress on the crop to an absolute minimum, making the AWB-1600 BAR equally effective for both ware and seed potato operations.

3 Point Hitch Potato Digger Applications

The 3 point hitch potato digger proves highly effective for potato and sweet potato harvesting on smaller to medium-sized farms where maneuverability matters most. Mounted directly to the tractor’s three-point linkage, it allows quick attachment and precise depth control, making it ideal for compact fields with standard row spacing. Growers appreciate how the compact design handles both early-season seed potatoes and late-season ware crops without excessive soil disturbance, delivering clean lifts that preserve tuber quality even in varied soil types common across North and South American operations.

When it comes to garlic, carrots, and beets, this versatile 3 point hitch potato digger adapts effortlessly by adjusting share blades and web tension for different root shapes and sizes. The same machine that extracts potatoes can gently undercut garlic bulbs or lift carrots and beets with minimal bruising, saving farmers the cost of multiple specialized implements. Many operators report consistent performance in lighter loamy soils or raised beds, where the direct tractor connection provides excellent stability and allows one-pass harvesting that speeds up the entire process from field to storage.

Onion harvesting rounds out the practical uses of the 3 point hitch potato digger, especially in regions where onions follow potatoes in rotation cycles. The gentle sieving action separates bulbs from heavy soil clumps while the side or rear discharge options keep crops organized for immediate sorting. Farmers who switch between these crops throughout the season value the quick setup and low maintenance, turning one reliable tractor attachment into a true multi-crop tool that boosts overall efficiency without requiring larger equipment investments.

Troubleshooting of 2 Row Potato Digger Harvester

1. PTO Shaft Not Engaging or Vibrating Excessively
   When the PTO shaft on the AWB-1600 BAR 2 row potato digger refuses to turn or shakes violently at 540 RPM, start by confirming the shaft length matches your tractor model and that the universal joints are properly aligned after transport. Worn splines or insufficient lubrication are frequent causes on trailed units. Clean the connection, apply fresh grease to all grease points, and tighten the locking pin. If vibration persists, replace the damaged joint before the next field run to restore full power to the webs and blades.
2. Vibrating Webs Stopping or Moving Slowly
   If the oscillating webs slow down or stop completely during operation, the drive chain or tension springs may have stretched or jumped off the sprockets after heavy use in wet clay. Stop the tractor, engage the parking brake, and inspect the chain tension and spring anchors. Adjust the tension bolts to factory settings and clear any wrapped vines from the drive area. This quick fix usually restores normal vibration within minutes and prevents further crop damage.
3. Inconsistent or Too-Shallow Digging Depth
   Share blades that fail to reach the correct depth often result from worn support wheels or loose hydraulic cylinders on the trailed frame. Measure the current depth against your potato variety requirements, then raise the machine and check wheel bearings for play. Tighten all pivot bolts and adjust the hydraulic depth stop to the required setting. Test in a short pass to confirm even lifting across both rows without missing tubers.
4. Excessive Soil Remaining on Harvested Potatoes
   When too much soil travels with the potatoes to the side discharge, the web vibration frequency is usually too low for the current soil moisture. From the tractor seat, increase the hydraulic flow to the web drive slightly while maintaining 5–8 km/h forward speed. If the problem continues, clean the web rods of built-up clay and check the angle adjustment rods for proper tension to improve separation without crushing the crop.
5. Potatoes Showing Bruising or Skin Damage
   Bruised tubers typically appear when web tension is set too high or the deviner web angle is too aggressive for the variety being harvested. Lower the web tension bolts by half a turn and reduce the share blade angle slightly. Run a test row and inspect the first 50 potatoes. This adjustment protects delicate skins while still delivering clean separation, especially important for seed potato growers who need undamaged stock.
6. Webs or Side Discharge Becoming Clogged
   Clogging with vines and wet soil usually happens when the optional Kit B or C is not fitted and field conditions turn sticky. Shut down safely, remove accumulated debris by hand from the main webs and discharge chute, then install the appropriate deviner kit for heavier foliage. Resume at a slightly reduced speed until the field dries. Regular cleaning every two hours during damp harvests prevents repeated blockages.
7. Hydraulic System Weak or Leaking Oil
   Weak response from the two control valves often traces back to low fluid level or a loose hose fitting after repeated folding for transport. Check the tractor reservoir first, then trace each hose from valve block to cylinder for leaks or abrasion. Tighten fittings and top up with the recommended hydraulic oil. Bleed air from the lines before returning to the field to regain precise on-the-go depth and speed control.
8. Machine Pulling to One Side During Operation
   If the 1350 kg trailed digger drifts sideways despite straight tractor travel, uneven tire pressure or a bent drawbar hitch pin is usually the culprit. Park on level ground, check both support wheel tires for equal pressure, and inspect the drawbar alignment with a straight edge. Straighten or replace any bent components and re-level the frame. This restores balanced tracking and prevents uneven row coverage across the full 1.6 m working width.
