Seasonal Tips & Tricks

KEMPER harvests more than maize!

Our customers are discovering more and more possibilities for harvesting thin stemmed crops with KEMPER rotary crop headers For example whole crop silage (WCS), rapeseed, Lucerne (alfalfa), field beans, miscanthus, sudan grass, sunflowers, hemp etc.

During the harvest of crops for the production of biogas or industrial plants which are harvested because for their fibres even chop length is very important. The gatherer and step type intake drums feed the crop into the centre forming an even ‘bundle’ transporting the plants lengthwise towards the feed rolls of the forage harvester. The SPFH is then able to produce the optimum chop quality.The universal KEMPER rotary crop header with its high speed cutting rotors has many unique advantages. Operating in open cut mode, the rotors cut stemmed crops across the entire width of the header. 


Operating instruction for WCS – harvesting

To harvest thin-stemmed plants effectively you need to take into account a number of factors and fit specific options. Due to the wide variety of crops and conditions we can only give general guidelines, however the following factors should be taken into consideration.

Technical Requirements

  • Clean out the area between the scraper fingers.

  • Adjust all scrapers as close as possible to the gather drums.

  • The cleaners of all drums must have sharp edges and the gap between the scrapers and the drums may not exceed 1 mm when rotating. The cleaners either can be changed, or built up by weld and ground back. Every tine row is equipped with one cleaner.

Attention: The front angle of the cleaners (yellow) in rotating direction has to be sharp – edged.

Intact cleaners are absolutely necessary. The flat cleaner on the bottom tine row is bolted on so it can be changed quickly.

Sharp blades are absolutely necessary.

At the beginning of each season you must check the main clutches to make sure they are not seized and will release in an overload situation.

During the harvest of crops with thin stalks the spring tension (F) of the front feedrolls must be reduced. Depending on the harvest conditions the tension may vary.

The feedrolls of the SPFH must be sharped-edged and aggressive.

Requirements and options only for 300-series

  • The crop needs to be dry.
  • Sharp-edged blades and special shaped cleaners are necessary.
  • Install the whole-crop silage kit
  • Install two-speed gearbox (if not already fitted). .
  • To achieve an optimal cut, the speed of the cutting rotors in WCS needs to be higher than during the maize harvest.Switch to the faster gear on both your SPFH and your header.
  • The faster you drive forwards the more regular the crop flow will be.
  • The field can be cut in any direction (not row dependent).
  • Maintain rpm when turning.
  • Starting up at idle speed will extend the life of the main clutches.
  • Keep all drives running when changing between trailers / trucks.

Modification measure for 300-series

On all rotary crop headers the two crop dividers between the two outer gathering drums (left- and right-hand sides) together with their support should be removed and replaced with short WCS tips.

The two outer divider points are fixed in their upper position with strip (A). The pointers in the centre need to be fixed in their upper position.

On pivoting points of the 360 and 375 rotary crop headers sickles should be installed.

Always install a two-speed gearbox.
