Innovative Patented Technology


Our patented SmartPan System is the only system available where the drop pan is protected by a cover while riding underneath the machine. Why? Because you don’t want any kernels or chaff contaminating the results by filling up your drop pan before it hits the ground. You want a true and accurate sample from the spot you want to measure.


Powerful permanent magnets attach the SmartPan Carrier Unit (1) to the machine.  This main pan stays on the machine during testing.*  Nested inside the carrier is one of two different style drop pans (2). This drop pan can be released on the go with a simple swipe in the app.

*Remove when not in use to avoid accidental loss or damage

Fast, Effective Sample Cleaning

Cleaning your sample just became a whole lot easier! Instead of wasting valuable time with hand sieves, or your own breath, we supply our customers with an air separator in every set.  Highly portable and equipped with a variable speed fan, this unit allows you to clean your sample within seconds compared to minutes wasted in the field. It will blow your mind, just as well as it blows the chaff and straw away from your grain kernels.

“Using sieves in the past took us easily 20min and more. The separator is a must have tool for us now.” Ian, Katanning – Australia

Air Separator - Updated for 2019

Precision Measurement

To put a number to your measured sample, we supply you with a high quality digital field scale. Weigh the grain sample and use our Bushel Plus APP for easy calculations. Dropping or spreading the straw, using chaff carts or seed destructors, our scenario based calculations will help you to put the loss in perspective. The APP calculates in both Metric and Imperial, and even let’s you save your machine and crop settings in your records.

Share your results with your drivers, team and friends by messenger or email. Access combine tips created from PAMI and the Canola Council of Canada to fine tune your settings.

NEW Smart Drop Feature

Control your Bushel Plus System conveniently through your smartphone.

At Bushel Plus, we have discovered an innovative way to design and build the SmartPan Carrier – a safe and remote way of releasing your combine’s drop pan via our Bushel Plus app.

With the “Wi-Fi Pan Control” feature, you can safely and remotely trigger the pan to release. Additionally, it provides two-way communication so you can get feedback on your pan release in real-time. Our system will notify you whether or not the pan dropped, making it easier to locate it in the field.

Therefore you will be able to tell if and exactly when the pan dropped in the field using the release trigger on your smart phone. No more scrounging about through dusty conditions hoping to see where your pan dropped.


Narrow Drop Pan

The 40 & 60” systems come with a narrow drop pan included. This works great for taller stubble conditions, like straight cut canola, hemp, corn and grain harvested with a stripper header.

The design of the narrow drop pan splits the stubble as it falls in between and can prevent the pan from tipping over. Stubble conditions are different in every field and every year, that’s why both style pans are included in the system. You always have the option to use either one on your farm.

Taking a field sample


Drop or spread your straw for testing? We help you with both!

  • We give you the option to check in both scenarios.
  • Attach the system to multiple locations on combine or header for different crop and stubble conditions.
  • Check your loss the way you combine.

The Flagship

40” – 1m

This is our most versatile DROP PAN!  It fits perfectly on the back axle, which allows you to check your losses from the rotor and the sieves.


It is great in high stubble crops (with stripper headers, canola, hemp, corn, sunflower, etc.). It fits beneath the feeder house, to be kept safe and high enough away from the tall stubble compared to the back axle mounting point.


When attached to the header, it allows you to understand your header losses as well as your losses while using a chaff spreader/chopper implement.


It is a must-have for anyone that is harvesting grains and specialty crops.


PRO-TIP: Use two FLAGSHIP solutions with our SMART DROP app and collect samples from the back axle and header at the same time. This allows you to truly understand your losses while harvesting in spread mode.

The Wide Setup

60” – 1.5m

This DROP PAN is for those growers and agriculturists that would like to take a slightly different approach to sample collection and combine calibration. It is great for collecting a sample from the entire width of the sieves while dropping straw and chaff in a windrow.

Bushel Plus Mini / Chaff Deck Version

20” – 0.5m

This is a terrific solution for plot and research combines – drumroll researchers and agronomists. The MINI is ideal for collecting samples in long stubble conditions with 30” row spacing (corn, sorghum, sunflowers, etc.) It fits between the wide stubble rows and works well with other implement options such as chaff decks.

  • Plot and research combines
  • Corn harvest with 30″ rows
  • ELMAR Chaff Deck
