ROTARY HEADERS

Models 9190 and 9192

Hesston offers a versatile line-up of headers - each one of them designed and built to deliver unrivalled reliability.

The new 9190 and 9192 rotary headers are designed for high production hay operations. The 16’ cutting width is designed to match a variety of customer needs and irrigation systems. The header features the new RazorBarTM low profile cutterbar with a spur gear cutterbar and a nodular iron casing. This cutterbar operates in a sealed common oil bath. Hydraulic conditioner roll tension and steel on steel herringbone rolls are standard equipment.

RazorBarTM Low Profile Cutterbar Features

  • Segmented disc modules made from nodular cast iron.
  • Sisu made cutterbed gears, designed to handle maximum torque loads, 100% of the time.
  • Larger cutting disc of 620mm, as compared to 600mm on the previous generation.
  • Faster tip speed of 189mph, as compared to 182mph on the 9170.
  • Increased disc overlap between disc for improved cut quality.
  • No need to split the cutterbed, all gears can be removed from the top of the gear bed.
  • Rock guards provide structural support for the cutterbar.
  • Drain and vent plugs have been relocated to the side of the cutterbed improving serviceability

The Model 9170 disc header is available with either a 15’ 3” cut or as a 12” model. The Model 9180 is only offered with a 15’ 3” cutting width.

Razorbar

Hydraulic Motor

The cutterbar is driven by a hydraulic motor on each side of the header.

The use of two hydraulic motors equalizes the torque load across the entire cutterbar, for longer life. Our competition uses a single drive motor on one side of the header. This causes torque loads to be greater on one side of the cutterbar, increasing component wear and leading to reduced cutterbed service life.

Sealed Bearings

The cutterbed bearings are sealed allowing a smaller volume of oil to be used in the cutterbed.

Sealed bearings have a longer service life as any contamination in the bed will not cause bearing failure. Longer bearing life makes for a long-life cutterbed, for less machine downtime.

The primary lubrication for the bearings is self-contained in the sealed bearing. The oil for the bed lubrication is mainly to coat the gear teeth, so the quantity of lubrication required for the bed can be reduced. This saves time and money when servicing the machine.

One-Piece Cradle

A one-piece cradle carries all the cutterbed gears eliminating the need for seals and preventing premature wear.

The one-piece cutterbed is solid so it does not flex, twist, or sag; this keeps the gears running true for reduced wear. For servicing, all drive and idler gears can be removed from the top of the cutterbed without loosing oil or replacing seals.

Hydraulic Tension System

The steel-on-steel conditioner rolls have a hydraulic tension system to maintain consistent conditioning.

The hydraulic tension system allows the operator to quickly adjust the conditioning roll pressure without the use of tools. A gauge and valve on the left side of the header makes tension changes simple and permits the operator to instantly determine how much force is being applied. A nitrogen charged accumulator allows the rolls to separate, letting slugs pass through without plugging.

ADVANCED CONDITIONER ROTARY HEADER

Advanced Conditioner System

The Model 9180 features a standard Advanced Conditioner System which has two sets of conditioner rolls...four rolls total to “double condition” the hay. The advanced conditioner system allows hay to dry faster so it can be raked and baled sooner.

Front intermeshing steel-on-steel rolls are followed by a rear set of intermeshing steel-on-steel rolls. Having two sets of rolls allows the crop to have twice as many crimps along the length of the stem to create more openings for moisture to escape, decreasing drying time. All four rolls feature a herringbone tread pattern which improves windrow formation, especially in light crop conditions.

Hydraulic Roll Tension

The advanced conditioner system uses hydraulic roll tension with an accumulator to keep pressure on the rolls and allow them to separate to prevent plugging.

Both front and rear rolls run on the same hydraulic circuit on the rotary advanced conditioner head. All four rolls are intermeshing steel rolls so no pressure difference is required between them, this lets the tension be set using one valve and gauge for all four rolls. A nitrogen charged accumulator is built into the system to let slugs pass through the rolls without plugging the head. Hydraulic tension increases efficiency by letting the operator quickly and easily set roll tension to match field conditions.
