Customer reviews
Andrei Ivanov · Professional Straw Recycling Contractor
This round baler is our primary workhorse,processing over ten thousand acres of straw in a single season.Its durability is impressive,with exceptionally reliable knotter performance and minimal twine breakage or downtime.The bales are firm outside yet fluffy inside,ensuring safe transport and ideal conditions for later ensiling,receiving positive feedback from our clients.
Hans Berger · Professional Silage Producer
The baling and wrapping combination machine is revolutionary.Its seamless integration of baling and wrapping increased our single-shift productivity by approximately 40%.The wrapping quality is consistently tight,ensuring optimal silage fermentation and significantly saving labor and time.
Erin Walters · Operations Director,Agricultural Services Company
The self-propelled baler proved its value across 5000 contiguous acres.The hydrostatic drive system reduces headland turning time by 40%,and the intelligent monitoring system displays real-time forage moisture and bale weight data.Most notably,its modular design allows core component replacement in just 2 labor hours,reducing annual maintenance costs by approximately$18,000.
Product Description
Features
This model is recognized for its sturdy gear-driven system and heavy-duty knotters,designed for enhanced durability and reduced maintenance needs.The"VarioDensity"infinite density adjustment system allows the operator to finely tune bale tightness based on crop type.The pickup features multi-point floating support and an optional central auger feed for aiming at a steady,even crop flow.The monitor provides knotter cycle counts and fault indicators to assist operation.

Specifications
Standard pickup width is 1.85 meters.Bale cross-section is approximately 36x42 cm,with length adjustable from 0.4 to 1.1 meters.The machine requires a tractor with a 540 rpm PTO.The bale chamber and plunger are built with reinforced steel plate,and key bearings and shafts are of a higher specification.Bale density can be adjusted manually or infinitely via a hydraulic valve,capable of producing tighter bales than conventional small squares.

Applications
Targeted at users with strict requirements for bale appearance and quality,such as professional stables,stud farms,and organic hay producers.The uniform,dense bales are ideal for manual handling,retail packaging,and export.The tight bale shape helps better preserve leaf and nutrients during storage,reducing waste.Also suitable for goat farms or special livestock operations requiring precise feeding management.
Frequently Asked Questions (FAQ)
Q:What size farm is a small square baler suitable for?
A:It's ideal for small farms,horse stables,or diversified operations under 100 acres.It has low investment and operating costs,producing standard small bales easy for manual handling,retail,and precise feeding.
Q:What causes frequent twine breakage during operation?
A:Common causes are:poor quality or incorrect twine;improperly adjusted or worn knotter parts;overly dry crop or hard contaminants;incorrect twine threading.Troubleshoot step by step.
Q:How to manually adjust bale density?
A:Usually by adjusting the tension on springs or hydraulic rods located on the side or top of the baling chamber.Increasing tension raises density.Fine-tune based on crop type;excessive density may overload the tractor and cause excess leaf loss.
Q:Can a small square baler be used for soybean straw?
A:Yes,but ensure the straw is thoroughly chopped,dried,and not too wet.Due to its smoothness,increasing density may be needed for a tight bale.Clean internal residue promptly after operation.
Q:Why are the produced bales of inconsistent length?
A:Main reasons:uneven ground speed;fluctuating feed volume(uneven windrow);worn or slipping metering wheel;unsynchronized plunger and knotter action.Consistent speed and uniform windrows are key.
Q:How to store and maintain a small square baler during the off-season?
A:Thoroughly clean the machine of all forage and debris.Lubricate all points with fresh grease.Release all tension springs.Store on a dry,level surface under cover,using blocks to support weight off tires.Apply rust preventive oil to exposed metal parts.
