Corn header PWL Master FLOW<\/span><\/h2>\n

MasterFlow is a corn header that was developed and designed in the smallest detail by professionals having long years of experience. These are machines with an optimally simple and durable construction. Thanks to the longest rotors available on the market, they beat records of operating speed up to 12 km\/h. As standard, they are equipped with the roto-cut propeller cutter, which shreds the stems at a speed of 25 m\/s. The continuous mass flow is guaranteed by the design of the section which prevents it from being clogged. Grain augers for lodged maize are always standard! The machines are available in working widths from 4 to 12 rows on a rigid frame and from 6 to 12 on a hydraulically folded frame.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

System roto-cut<\/em><\/strong><\/p>\n

Excellent cutting quality<\/h3>\n

It can be engaged or disengaged with a key. Directly connected to the harvest drive gearbox. Mounted directly at the back of the section and equipped with 60 HRC steel knives with tungsten carbide. These are the advantages of the stripper section. The position of the cutter at the rear directly under the main gearbox reduces the risk of collision with the ground, which extends the life of the blades. It also eliminates the need for additional drive gearboxes. The cutter knives cut the maize at a speed of 25 m\/s measured at the blade tip. There are 2- and 3-knife cutters to choose from.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Gearboxes in cast-iron housings<\/strong><\/p>\n

Durability is paramount<\/h3>\n

The heart of any corn header is its gearboxes. Therefore, it is their construction that must ensure a long, defect-free operation of the entire machine. We know that the conditions during the harvest are not always ideal. Therefore, the gearboxes of PWL headers are enclosed in strong cast-iron housings which are able to deal with unforeseen load during operation. Bevel gearboxes in oil bath with carbon steel gear wheels with a hardness of 50 HRC will ensure long, defect-free operation.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Long service life of working elements<\/strong><\/p>\n

First of all, low-cost operation<\/h3>\n

The working elements of each stripper section are made of wear-resistant materials and covered with tungsten carbide. Its hardness exceeds 60 HRC. This allows for a very long operation period of up to 200 ha per row. The design of the rotors allows for maximum use of the blades, which after being worn off can be reversed, so that the sharp edge faces the opposite direction. Counter-knives with the possibility of adjusting the distance from the knife allow you to work in the most difficult, wet, weed-infested conditions without compromising work efficiency. They also prevent plants from wrapping around the rotors.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Long working sections<\/strong><\/p>\n

Exceptional efficiency in all conditions<\/h3>\n

The operation of headers for maize harvesting is determined by the length of the rotors and their rotational speed, which is why in PWL headers both of these aspects are harmoniously matched. There is a rule: the longer the rotor, the higher the operating speed at which we can work. On the other hand, the proper rotational speed of the rotors reduces grain losses. Rotors with a total length of 680 mm and an input speed at the gearbox of 620 rpm are employed in the headers. This allows operating speed of up to 12 km\/h with losses reduced to minimum.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Adjustment of the stripper\u2019s deck plates<\/strong><\/p>\n

Central adjustment system for the stripper\u2019s deck plates<\/h3>\n

In the headers, a central adjustment system for the stripper\u2019s deck plates is used, thanks to which the gap is adjusted depending on the input from the operator\u2019s cabin. Depending on the combine model, a hydraulic or electric actuator is used for this purpose. If it is necessary to calibrate individual sections, the second deck plate of the stripper is adjusted manually using screws. The smooth mass flow is also ensured by chains operating on large-diameter gear wheels. Therefore, the chains are closer to the gap of the stripper, eliminating corncob clipping and also eliminating the need for continuous adjustment of the stripper\u2019s deck plates.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Universality<\/strong><\/p>\n

Customised solutions<\/h3>\n

PWL headers can be mounted on absolutely any combine harvester. No exceptions. For this purpose, an appropriate mounting frame, hydraulic couplings system and appropriate reduction in the main drive gearboxes are selected. Machines become more universal, because regardless of the combine model, they can always be adapted. Tilt adjustment and universal frame settings allow you to choose the best working angle of the header and adapt it to the working conditions.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Crop dividers<\/strong><\/p>\n

Minimise losses<\/h3>\n

Row covers and crop dividers are made of flexible lightweight plastic. They minimize crop losses when corncobs fall on the covers. They limit the total mass of the machine and ensure a smooth mass flow. Divider widths with row spans of 70 and 75 cm are selectable.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

ome things just should be standard. Therefore, PWL headers are always equipped with side spirals for lodged maize. Conical side spirals are simple, light and durable. They ensure high work efficiency in maize damaged by animals and pests.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Drive transmission<\/strong><\/p>\n

Durable solutions, solid drives.<\/h3>\n

The drive of rigid headers is transmitted externally from the machine through cast-iron angular gearboxes and power take-off shafts. They ensure low maintenance requirements, long service life and reliability.
\nThe headers with a hydraulically foldable frame have a drive chain from the inside of the header and central trapezoidal couplings. The drive is engaged without leaving the cabin, and the loads on the couplings are limited only to the operation of the lateral working sections.
\nThe machines are protected by a central friction clutch protecting the entire machine against mechanical damage caused by sudden jams of the strippers. This solution allows you to achieve a higher working speed.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Active chain tensioners<\/strong><\/p>\n

In PWL headers, the chains are tensioned automatically through internal springs. They ensure proper tensioning of the chains during operation, and also facilitate maintenance and service, because after loosening one screw, the chain can be easily removed and replaced.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
