HIGH PERFORMANCE (HP) CLEANING SHOE ELEMENTS Improves tailing volume and tank sample, especially in challenging conditions, such as canola, lentils, weedy conditions, and heavily bearded crops. The newly designed louvres of genuine HP elements will ensure a lot more even air flow. You get more combine capacity even in high yielding or brittle crop conditions, and will prevent grain losses caused by shoe overloading. Note: When using HP cleaning shoe, elements must be set with more spacing and combine with more airflow for best results. Inquire at your nearest Western Tractor branch for more details.
GP Chaffer
HP Chaffer
At the suggestion of our local Western Tractor dealer, we had the chance to try out the High Performance (HP) Chaffer in one of our S780 combines. Installation was relatively simple and was done in-field very quickly. Several loss pans were observed throughout our trial of the HP chaffer to ensure both combines were running at peak efficiency and limiting our losses.
We did try the HP chaffer on other crops as well. Peas and lentils saw a reduction in the number of pods in the sample. Wheat and durum harvesting had a modest increase in combine speed, again, attributed to a wider opening and reduced losses. Sample was also cleaner in cereals over a GP, but not the extent a person would see in canola.
The benefits of this design are the most apparent when harvesting canola. A sample that would normally contain an acceptable amount of chaff with a General Purpose (GP) chaffer, becomes substantially cleaner with the HP chaffer installed. We ran one combine with a GP and the other with an HP and there is an uncanny difference when unloading into the cart as to which pile is which.
All of this would not have been possible without the tremendous support from Western Tractor. They were available to answer any questions we had and made sure the chaffer was doing the job that we wanted it to. They were also very thorough on data collection whether it was following up on the results of each crop or observing the combine’s settings. This knowledge will be incredibly valuable in the future when setting up other machines or having consultations on whether the HP chaffer is right for your operation. Overall, we were pleasantly surprised by the results. Operations that are primarily harvesting small grains should consider the High Performance chaffer as a way of increasing machine efficiency and cleaning up your sample.
Another benefit is the increased speed at which the combine is able to travel in canola. Chaffer loss is one of the limiting factors when trying to push our machines to peak efficiency. The HP equipped combine was able to travel 10-20% faster than the GP equipped machine. This is due to the wider opening that is required of the HP chaffer allowing all seeds to pass through while still grabbing foreign material and letting the fans to do their job. The sieve settings on the two machines stay about the same depending on conditions.
