HOW IT IS MADE

Disc mower PRONAR PDF301C

Disc mower PRONAR PDF301C is a front disc mower with condicioner which is mounted on the tractor’s three-point linkage. The mower requires PTO at the front of the tractor and one hydraulic section. Disc mower PRONAR PDF301C was designed primarily for working on heavy, uneven terrain. Its main element is the proven and reliable PRONAR cutting bar, guaranteeing high quality of mowing. The robust construction of the machine is based on modern materials and latest production technologies. In combination with a large ground following ability, the PDF301C can handle work in all conditions, while maintaining an excellent cut quality. Mower’s mowing performance, at a speed of 10km / h, is 3 ha / h. To operate disc mower PRONAR PDF 301C, only a 75 hp tractor is needed

Disc mower PRONAR PDF301C – main features:


Disc mower Pronar PDF301C is equipped with a tine conditioner that accelerates the process of drying the swath, which allows to increase the yield of the forage harvest. The degree of conditioning of the material can be adjusted depending on the needs and type of mown grass. The conditioner drive was moved to the right side, balancing the angular drive of the slat drive, located on the left. Thanks to this solution, the cutting and loosening unit always stays in balance, which ensures even pressure of the cutter bar on the ground.
Disc mower PRONAR PDF301CThe wide range of ground copying of disc mower PDF301C is one of its biggest advantages – it is 700 mm (450 mm / 14 ° up, 250 mm / 10 ° down) and the cross-copying range is 24 °. This ensures perfect adhesion of the cutter bar to the ground at a constant angle (regardless of field conditions) and clean and aesthetic cut.
Two strong flotation springs regulate the pressure of the cutting and loosening unit on the ground.
On the mower’s suspension the cutting and loosening unit is mounted in a trailed system, thanks to which the PDF301C – when encountering an obstacle (e.g. stone) – can freely defeat it.
The drive disk provides easy access to the drive connector without removing the slat from the mower’s frame.
PRONAR cutting bar is a high-strength cutting bar with an additional stiffening profile enclosed in the body of the slat. It is equipped with discs of innovative shape, what provides lower cutting resistance and lower power demand per unit of cutting width. The enlarged, high-quality gears used in the slat have low noise emissions, thanks to which the mower works quietly. Such option significantly influences the comfort of work.
Additional protective skids, made of hardened, abrasion resistant steel, are mounted as standard. Thanks to them, the cutting bar is additionally protected against mechanical damage. The operator can easily replace them after use.
Operating the mower is facilitated by the system of quick replacement of knives. The operator can replace worn knives at any time, without having to unscrew the cutter bar, thanks to a special tool, made of durable steel, making it easier to change them. In addition, the standard equipment of the mower is an additional set of knives.
Thanks to folding side covers, the width of the mower in the transport position does not exceed 3 meters. Disc mower PRONAR PDF301C
The swath width adjustment range is from 1.34 to 2,04 and it is carried out by two scrapers.
Aprons ensure safety during work, and an easy way of lifting them. This allows the operator a quick replacement of knives, control of the technical condition of the machine or supplementation of operating fluids without the need of disassembling it.

Disc mower PRONAR PDF340C

The PRONAR PDF340C disc mower is a front-mounted mower with swath conditioner mounted on the front three-point linkage. To operate the mower, the tractor must be equipped with a front three-point linkage and one hydraulic section. The mowing width is as large as 3.4 m, which significantly increases the efficiency and functionality of the machine. The PRONAR PDF340C disc mower is designed primarily for mowing on difficult and uneven terrain. Its main component is a durable and reliable PRONAR cutter bar, which is equipped with an additional stiffening profile enclosed in the cutter bar body. A sturdy machine design is based on modern materials and production technologies. Safety of use is ensured by a 1200 Nm friction overload clutch. With its very flexible ground surface tracking, the PRONAR PDF340C disc mower can cope with all conditions, while maintaining excellent mowing quality. The mowing capacity at a speed of 10 km/h is 3.4 ha/h. A tractor with a power of at least 95 HP is required to drive the PRONAR PDF340C disc mower.

Disc mower PRONAR PDK220

PRONAR PDK220 rear mounted disc mower is a compact, robust, characterized by lightweight structure where PRONAR cutter bar is applied. PRONAR disc mower can be easily mounted on various tractors. Minimum tractor power requirement for this mower is 30 hp. Classic suspension guarantees uniform pressure of cutter bar on the surface. Disc mower PRONAR PDK220 has three transport positions which is a big advantage among other mowers manufacturers.
Floating position of the hydraulic lever guarantees smooth drive transmission even on large irregularities of the ground. Side suspension allows to mow on the slopes ranging from + 900 up to -220. The mower is protected by a safety fuse, which at the time of collision with an obstacle slides apart and the mower is moved backwards minimizing the possible effects of the impact.

About 50% lower power consumption compared to drum mowers.
Spring tensioner reduces fuel consumption and attrition of the cutter bar.
Extensive range of inclination facilitates enables operation on uneven and steep surface.

Disc mower PRONAR PDT260

Disc mower PRONAR PDT260 – central suspension which was used in the mower ensures an excellent operation on uneven and steep surface, clean and aesthetic cut and also optimum cutting height. Another advantage of this design is the three – step adjustment system of stay springs – 70, 80 or 90 kg which guarantees optimum pressure of the mower on the ground depending on the type of surface from soft soil, peat, up to the hard and dry. Extensive range of inclination (-16º to + 11º) facilitates operation on uneven and steep surface.
All components in direct contact with the ground are made of hardened boron steel.

Transporting the mower can take place in three different positions:
