Harvest Monitor is an industry-exclusive technology from John Deere. Harvest Monitor gathers and analyzes valuable harvest information, enabling sugarcane producers to make smarter decisions that drive down harvesting costs and improve overall farming practices.
From the cab, the operator can monitor total tons harvested, harvester productivity, trash percentage, and fuel consumption. The operator can then use this information to make on-the-fly adjustments to optimize performance.
SmartClean system is the latest enhancement of Harvest Monitor that allows automatic control of primary extractor fan speed based on the operator’s preferences in order to obtain the most profitable balance between cane cleanliness and reduced loss.
Through the John Deere Operations Center, the data can be processed to generate yield and other valuable maps and reports that will guide producers into making the right decisions on soil and water management, chemical application, crop renewal, field layout, equipment logistics, and much more.
Harvest Monitor is much more than just a yield monitor. It includes:
Harvest Monitor was designed to operate efficiently in all weather conditions. It is a low maintenance system with no additional wear items thanks to its optical technology that does not require direct contact with the cane.
High-resolution, stereoscopic optical sensors and pattern recognition technology are used to scan the flow of cane as it passes through the elevator, identifying cane volume and differentiating it from trash. Four light-emitting diode (LED) lights illuminate the sampling area to ensure uninterrupted visual clarity.
The system converts the volumes to mass in order to obtain tons of cane and extraneous matter level.
With the use of sensors, the SmartClean system detects cane being lost through the primary extractor and displays it on the CommandCenter screen as an index. The level of residue or cane leaves being removed is also detected and displayed as an index.
Aiming at the best economic outcome for the operation, the operator selects the target level of the following parameters and lets the system continuously and automatically find the appropriate primary extractor fan speed:
SmartClean enables operational consistency throughout the day regardless of weather conditions and individual operator practices. Understanding the residue level is important for biomass power generation projects to determine residue collection logistics and viability.
Data points are georeferenced to precise field locations using global positioning system (GPS) technology. With appropriate software, a variety of informative maps can be generated. The system operation requires a GPS receiver.
With SmartClean activated and based on live information, the operator can make other quick adjustments to the harvester, like ground speed and FieldCruise™ settings, to maintain the most profitable harvesting rate while delivering the preferred level of cane quality and reduced loss.
While harvesting, the display will show:
The CommandCenter display layout is configurable so the operator can have Harvest Monitor and SmartClean system displayed together on the same screen. Average, best, and current values of extraneous matter, fuel consumption, and pour rate are displayed instantaneously or as historical figures. Also available on the display is a summary report of all data.
A yield map can also be seen on the display, as well as live video of cane as it flows through the elevator.
To keep records of the number of wagons completed, the operator will click the “Save Load” soft key every time a unit is loaded. The screen will show the total loads from a field, shift, whole season, or another preselected period of time. The sugar mill destination can also be recorded for each load.
The information may also help to determine if the chopper and extractor fan blades need to be replaced, or if other related service is required in order to maintain optimum operating performance.
The live yield data simplifies daily logistics decisions, including the number of transport units required and the correct timing to efficiently complete the assigned cane quota. In addition, field harvesting progress and remaining unharvested area can be seen on the screen for a great visual of the operation that can facilitate the transition to the next field.
Georeferenced samples that include elevation readings are taken every second. As the harvester travels down each row, numerous elevation readings representing the topography of the area harvested are recorded.
Example of a typical field:
The maps and reports will help to determine the best solutions for:
Information can also be used to evaluate results of previously implemented solutions to make adjustments if needed.

The Harvest Monitor data can be processed through John Deere’s Operations Center to generate maps and reports that will help optimize operations.
Different types of maps can be created for a clear visualization of current farm conditions:
During harvesting, Harvest Monitor can be calibrated manually by entering weight information for the load supplied by the mill or from a weight wagon on operations that use it.
The maps can also be calibrated using field report data supplied from the sugar mill.
The John Deere CH9 Series Two-Row Harvester provides double the productivity of a single row-unit in most conditions by harvesting two rows of cane simultaneously at the same speed.
Since the CH9 Series models harvest at the same speed as the single-row units in most conditions, the wagons are loaded in half the time, reducing total infield transport equipment cycle time considerably. In a typical operation, this translates into 50 percent fewer harvesters, 28 percent fewer tractors and wagons, and 36 percent fewer operators required per front while saving 30 percent in fuel. In multi-front operations, this additional harvesting capacity can also be used to decrease the number of fronts by increasing their quotas. Regardless of the solution adopted, the total number of operators, tractors, wagons, and harvesters is reduced significantly.
The CH9 Series tread matches the row spacing so the tracks travel centered on the interrow away from the stubble. By straddling two rows, the center interrow remains untouched, leaving 50 percent of the rows are undisturbed. In addition, the compacted area is reduced by 60 percent, fostering better growing conditions for improved yield and ratoon life.
By straddling two rows, the center interrow remains untouched so 50 percent of the rows are undisturbed. In addition, the compacted area is reduced by 60 percent. Thanks to better cane growing conditions fostered by the John Deere two-row harvester system, improved yield and ratoon life are expected.
Wider entry to the primary extractor, less billet contact with the fan, and a 78 percent larger secondary extractor reduce cane loss while maintaining low extraneous matter levels. In addition, only 50 percent of the uncut rows are exposed to contact with the harvester for further loss reduction.
Twice the pour rate of a single-row unit required reengineering of the cleaning system to deliver high-quality cane. The CH9 Series Sugar Cane Harvester optimizes the use of the primary extractor cleaning area with wider entry offered by the longer chopper drums. It is in this first section where most of the trash removal takes place. Relocating the fan further back and tapering the cane inlet greatly contributes to cleaning efficiency and reduced loss.
Lower loss is also possible thanks to the higher cane flow that minimizes the risk of billets being pulled away by the fan.
A redesigned, higher-capacity secondary extractor with tapered inlet and 78 percent larger area provides even more cleaning before the cane is loaded into the wagon.
The John Deere CH9 Series Two-Row Harvester was designed with both durability and value in mind. CH9 Series components can handle the most unforgiving conditions while providing dependable performance throughout the harvest. Longer life and ease of service dramatically reduce downtime and boost productivity, putting more money in your pocket where it belongs.
The CH9 Series components have been overdesigned to ensure long-term durability. The John Deere 13.6L (830-cu in.) engine is 50 percent larger than the CH570 9.0L (549-cu in.) engine, and the Tier 3 option uses no more than 70 percent of the maximum power capacity available for other applications. The harvester uses John Deere 850 Crawler Dozer tracks that are two levels above the single-row tracks and won’t need to be refurbished during the season. The elevator is 30 percent larger, and it uses harden steel floors, strips, and sprockets plus heavy-duty slats and bearings. Higher torque capacity gears and bearings are used on the final drive, which provide 60 percent longer life.
With the John Deere exclusive RowAdapt system, the CH9 Series Sugar Cane Harvester adjusts automatically to different row profiles, row cultures, and changing terrain.
Once the contour basecutter height control and floating crop divider have been enabled, the RowAdapt system is ready to go to work.
The basecutters are independent and will accommodate height differences of up to 200 mm (7.9 in.) between the two rows being cut on uneven terrain.
The crop divider floating control system is calibrated so that the appropriate pressure is exerted on the interrow to allow the base of the crop dividers to barely contact the ground. At the same time, it keeps the toe under lodged crop so that the scrolls lift up and feed the cane effectively into the harvester throat.
The contour basecutter height control system uses the crop dividers’ position and disk cutting pressure inputs to operate. The system automatically adjusts to the target cutting height selected by the operator.
