HARVEST REPORT – Wednesday 22nd December 2021

Most areas have started into their wheat and Cereal Crops. Yields are varied but common to see over 5 tonnes per hectare.

The high yields and sometimes down crop means the combine has to process a lot of more material. This can affect through-put and increase grain loss.

One issue we are now seeing is the grain leaking from the fan area. On the ground this looks like a trail of concentrated grain inside the wheel tracks. This is more common on the right hand side but can be right across the machine.  This is caused by free grain falling through the front of the chaffer and overloading the front of the sieve then running into fan housing. This loss is not picked up with grain loss sensors, but you will notice yield drop off as speed is increased.

 

There are a few ways to help combat this issue.

  1. Make sure the cleaning shoe is balanced – adding separator filler plates and adjusting slides on shoe augers can help. The Rotor speed and concave clearance can also affect where and how much material comes out of the concave and separator.
  2. Closing down the adjustable pre-cleaner if fitted can help move material back further on the chaffer to help prevent too much grain coming onto the front of the sieve.
  3. Closing down the top chaffer will also help move material back further. Also, check the manual adjustment on the top chaffer. This should be around 10mm
  4. The most effective solution is to open the bottom sieve in increments until the grain trail disappears. Generally over 10mm will put you out of the danger zone.
  5.  

Samples can be affected by the wider sieve setting. A higher fan speed can help remove light trash. If whitecaps are your problem, try tightening the concave or adding some bands or more wires to improve the threshing.

This grain loss can be misinterpreted as rotor or shoe loss and you might think the machine is at capacity. Once addressed you may have a significant increase in performance with minimal grain loss.

2021 HARVESTER CLINIC

Taking a moment to set up before harvest can be time well spent. Our 2021 Harvester Clinics are designed to help you get to know your harvester and learn all about its capabilities before harvest really kicks into gear and also familiarise yourselves with the latest in Machine technology.

Due to the ongoing COVID-19 restrictions, we have had to do things a little different again this year, giving you to opportunity to view the videos online, rather than having the Harvester Clinic face to face.

Below we will spend time walking around the harvester fronts, we will discuss all of the daily maintenance points and checks on the S700 Combine, Threshing and Separating, Residue Management, Grain Loss, the safety points on the S700, the cleaning system, and we will walk you through the Power Shutdown and Performance Indicators of the S700 Series Combine.

We will then run you through the technology built into your John Deere S700 and X9 combine so you can improve the productivity and efficiency of your harvesting operation with ease.
