Buy a trailed double-bar mower: price from the manufacturer 2026 

Buy a trailed double-bar mower: direct deliveries from the manufacturer in 2026

If you are planningbuy a trailed double-bar mowerto mechanize forage harvesting or landscape maintenance, the key success factor is not only the price, but also the matching of the unit to the power of your tractor. In 2026, the market for industrial agricultural machinery has shifted towards modular solutions with a reinforced frame and hydraulic blade drive. A trailed double-bar mower (DDM) is a heavy class of equipment designed to work in conjunction with tractors of the 1.4–3.0 traction class (MTZ-82, John Deere 6-series, Kirovets K-700). The main advantage over mounted analogues is the stability of following the terrain and the ability to mow tall stalks (alfalfa, corn for silage, weeds) without the risk of overheating the tractor transmission.

Our production offers units certified according to EAEU and ISO 9001 standards, with a frame warranty of up to 5 years. We eliminate the intermediary markup by providing the price from the manufacturer. Below is a detailed technical analysis to help engineering services and purchasers make an informed decision about introducing this equipment into the fleet.

Design features and principle of operation of a trailed double-bar mower

A trailed double-bar mower is a complex kinematic system where the torque from the PTO (power take-off shaft) of the tractor is converted into the reciprocating movement of two independent blade bars. Unlike rotary mowers, which chop the crop with centrifugal force, bar mowers cut it, which is critical to preserving the nutritional value of the feed and reducing energy costs.

Kinematics and drive mechanism

The heart of the unit is the gear-crank mechanism. In the 2026 models, we use reinforced gears made of 40X steel with HFC (high frequency current) hardening. This solves the main problem of previous generations - tooth wear when operating at high speeds (540 or 1000 rpm).

• Front and rear beam:They work in antiphase or synchronously (depending on the setting), which compensates for lateral loads on the tractor frame.
• Balancing system:Spring or hydropneumatic compensators allow the beam to “float” along the soil, repeating unevenness with an amplitude of up to ±15 cm.
• Knife apparatus:Consists of segments with double-sided sharpening and pressure plates. The gap between the segment and the plate is adjustable within 0.1–0.5 mm, which ensures a clean cut even on wet grass.

Engineering practice shows that it is the accuracy of gap adjustment that affects the quality of the cut by 70%. If the gap exceeds 1 mm, the stem does not cut, but breaks, which leads to loss of juice and rapid oxidation of the mass.

Frame and transport system

The trailed design requires its own chassis. We use axle beams from trucks (GAZ/ZIL modifications) or specialized axles with brake drums. This allows the mower to be safely transported on public roads at speeds of up to 40 km/h. The frame is welded from channel No. 16–20, which provides torsional rigidity when working on slopes.

Specs: What to look for in a 2026 spec

When choosing a model, it is important to compare the parameters of the mower with the energy capacity of your tractor. Below are the average technical data for a standard trailed double-bar mower with a working width of 2.1–2.5 meters.

Important:Do not confuse power consumption with tractor engine power. For reliable operation of a mower that consumes 40 kW, the tractor must have an engine with a power of at least 60–70 kW (about 80–95 hp) to compensate for losses in the transmission and provide traction on hills.

Areas of application and economic efficiency

Request "buy a trailed double-bar mower» most often comes from agricultural holdings and farms working with perennial grasses. Let's consider two real-life use scenarios that confirm the profitability of this equipment.

Scenario 1: Making alfalfa and clover haylage

Alfalfa has a delicate stem structure. Rotary mowers often "beat" the leaf, which contains the bulk of the protein. The double-bar mower provides a clean cut while maintaining leaf mass.

Efficiency calculation:

— Area: 100 hectares.

— Work speed: 1.2 ha/hour.

— Clean mowing time: ~83 hours.

— Saving of feed units: up to 15% compared to rotary analogues due to lower leaf losses.

— Payback of additional quality: 1 season with intensive use.

Scenario 2: Maintenance of areas and mowing of tall crops

Utilities and hunting farms use the KDP for mowing reeds, weeds and shrubs with a diameter of up to 15–20 mm. Thanks to the massive frame and the inertia of the flywheels, the double-bar mower copes with loads that stop light mounted models.

Technical nuance:When working with wood shoots, it is recommended to install reinforced shear plates and increase the frequency of sharpening the segments.

How to choose a supplier: quality assessment criteria in 2026

The market is saturated with offers, but not all manufacturers comply with GOSTs and technical regulations. To successfullybuy a trailed double-bar mowerand avoid experiencing equipment downtime during the season, pay attention to the following aspects:

1. Availability of our own design bureau and production.Avoid companies that only assemble equipment from Chinese components without quality control of the metal. Ask for a certificate of the steel used for knives and bars.
2. Availability of spare parts.Knives, segments, pressure plates and bearings are consumables. Check to see if there is a spare parts warehouse in your region or what the delivery time from the factory is.
3. Warranty conditions.The standard warranty for agricultural machinery is 12 months. However, leading manufacturers provide an extended warranty on the welds of the frame and gearbox housing.
4. Possibility of modernization.Modern mowers should be able to install hydraulic beam lift (optional). This allows you to clean the blade unit from adhering dirt or lift it over obstacles (stones, stumps) without leaving the tractor.

Expert advice:Before purchasing, request a video of a specific model working in a field similar to yours in terms of terrain and type of vegetation. Static photos in the catalog do not show the dynamics of soil copying.

Comparison: Trailed vs Mounted double-bar mower

A frequent question from buyers: why is it worth overpaying for a trailed structure if a mounted one is cheaper? The answer lies in the life of the tractor and the quality of work over large areas.

If your fleet consists of light universal row-crop tractors (for example, MTZ-80/82), a trailed model will be the best choice for preserving the life of the front axle and the tractor’s hydraulic pump. For heavy, energy-intensive machines, the difference is less critical, but the trailed design still benefits in operator comfort.

Pricing: what makes up the cost in 2026

The price of a trailed double-bar mower varies depending on the configuration and order volume. Direct purchase from the manufacturer (price from the manufacturer) allows you to save up to 25% compared to dealer networks.

Factors influencing the final price:

• Metal content:The cost of steel and welding works is up to 40% of the price of the unit.
• Accessories:The use of imported bearings (SKF, FAG) or cardan shafts increases reliability, but increases the price. Russian analogues (VPZ, BZA) are cheaper, but require more frequent replacement.
• Options:Hydraulic cylinders for lifting beams, automatic lubrication, additional sets of knives.
• Logistics:Delivery of oversized cargo (width more than 2.5 m may require special permits) is included in the estimate.

In 2026, there is a tendency for logistics to become more expensive, so many farms prefer to order a batch of equipment at once in order to optimize transportation costs. We offer a flexible system of discounts for wholesale buyers and cooperatives.

Operation and Maintenance: Extending Service Life

Even the most reliable equipment requires proper maintenance. The experience of chief mechanics shows that 80% of breakdowns occur due to violation of maintenance regulations.

Shift maintenance (TO-1)

• Cleaning the knife apparatus from plant residues. Sticky grass causes imbalance and overheating.
• Checking the tightness of bolted connections, especially the fastening of beams to the frame and knives to the segments.
• Visual inspection of the driveshaft for cracks and protective covers.
• Lubrication of universal joints and chassis bearings (grease nipples).

Seasonal maintenance (TO-2)

• Changing the oil in the beam drive gearbox (usually TAD-17 or analogues SAE 85W-90).
• Defects of knives and segments. Replace worn elements in pairs to maintain balance.
• Checking the pressure in the chassis tires.
• Anti-corrosion treatment of exposed metal surfaces before winter storage.

Engineering lifehack:When storing during winter, lower the mower onto wooden stands to relieve pressure on the tires and suspension springs. It is recommended to lubricate the knife bars with preservative oil and cover them with an awning from moisture.

Typical mistakes when purchasing and using

Analyzing calls to the service center, we identified the main mistakes that should be avoided if you decidebuy a trailed double-bar mower:

1. Tractor power mismatch.An attempt to combine a heavy trailed mower with a tractor with a power of less than 60 hp. leads to slipping and burning of the clutch.
2. Ignoring the phasing of knives.After assembly or repair, the blades on the front and rear beams must be installed correctly. If they hit each other, instantaneous destruction of the cutting apparatus will occur.
3. Working at high speed on uneven surfaces.Speeds exceeding 10–12 km/h on a lumpy field result in beams “bouncing” and segments breaking on rocks.
4. Lack of driveshaft protection.A rupture of the protective cover leads to the tape wrapping around the shaft, which can cause an accident.

FAQ: Frequently asked questions about trailed double-bar mowers

Q: Can I cut wet grass with a double bar mower?
A: Yes, bar mowers handle wet material better than rotary mowers, since they cut it rather than chop it. However, the driving speed should be reduced by 15–20% to avoid sticking.

Q: What kind of tractor is needed for aggregation?
A: Tractors of traction class 1.4 (MTZ-82, YuMZ-6) and higher are optimally suitable. The presence of a rear linkage and a PTO is mandatory. For a trailed model, it is also important to have a working tractor brake system or the presence of autonomous brakes on the mower.

Q: How long do knives last?
A: The service life depends on the abrasiveness of the soil (sand dulls knives faster) and the presence of stones. On average, one set of knives lasts 40–60 hours of pure work time before the first sharpening. Complete replacement is required after 2-3 seasons.

Q: What is the main difference between a double-bar mower and a single-bar mower?
A: The double beam has a double working width and better balancing of lateral forces. The single-bar beam is simpler in design, but creates a significant lateral load on the tractor, which impairs controllability.

Q: How to order spare parts?
A: All drawings are unified. You can order a repair kit (knives, segments, fingers) directly from us by filling out an application through the website. The shipment time from the warehouse is 1–2 days.
