Confidently hit loading targets with SmartWeigh™, John Deere’s unique payload weighing system
Loader weighing material in the bucket
Overview
SmartWeigh™ is a John Deere designed and supported payload weighing solution that delivers accurate measurements, dynamic weighing capabilities, and is easy to calibrate. For those not sold on whether or not a payload weighing solutions is a fit for your application, John Deere offers a low cost 250-hour trial period that provides you full SmartWeigh™ capabilities to help enable you to make the decision.
Benefits
- Leading Accuracy: SmartWeigh™ provides operators with increased accuracy (+/- 1.5 percent) because of John Deere’s expertise knowledge of our loader’s kinematic properties and exact dimensions and specifications. This ensures near exact target weights are hit and efficiently loaded into feed mixers, trucks, hoppers, or processing plants. This also helps prevent the loader from having to go back to the pile to get more material or to dump excess material.
- Seamless Calibration: Unlike other payload weighing systems, SmartWeigh™ does not need to be calibrated with a known weight and is designed to be easy to complete without the help of a dealer. By going through an easy-to-follow calibration process in the machine monitor, the system will be ready to accurately weigh material.
- Dynamic Weighing: There’s no need to constantly lower and reraise the boom of the loader to determine the weight after tipping off material. Bucket capture height can be set anywhere from 15-90 percent of boom height and can be captured at any boom speed. The SmartWeigh™ system can automatically determine the new weight after tip offs, reducing the time it takes to load the exact amount of material.
- John Deere Designed and Supported: SmartWeigh™ is a John Deere designed and supported solution meaning if issues arise, the only call you need to make is to your John Deere dealer.
- JDLink™ Integrated: Integration of payload weighing data into JDLink™ means that you can access the data from nearly anywhere, not just within the cab of the machine.
- Factory and Field Kit Options: A range of options are available to equip John Deere utility loaders with SmartWeigh™ including fully integrating from the factory or adding through field kits. The 250-hour trial period enables you to utilize SmartWeigh™ for 250 machine hours and decide if you would like to easily add on the feature for the life of the machine after the trial period expires.

Auto Level enables near complete parallelism and buckets and optimized Z-Bar linkage allow you to move more material and reach higher
644 P-Tier loader with standard Z-Bar Linkage
Improved bucket rollback and material retention
Overview
New P and X-Tier utility loaders will now be equipped with Auto Level that enables near perfect parallelism throughout the boom raise and lower cycle. In addition, enhanced performance buckets and Z-Bar linkage on P and X-Tier utility loaders are designed to enable loaders to be configured in a manner that allows them to be as productive as possible.
Benefits
- Auto Level can be enabled through the primary machine monitor and allows operators to set their desired attachment angle and keep that angle within +/- 2 degrees throughout the entire boom raise and lower cycle. This minimizes load rollback when using forks or buckets to improve load leveling
- Auto Level currently not available on machines configured with Tool Carrier linkage
- 8 degrees of parallelism is achieved when Auto Level is disabled
- High-Lift linkage adds an additional 304.8 mm (12 in.) of hinge pin height over standard linkage
- Cross tube and boom geometry design offers improved visibility to front attachments when operating and changing out between attachments during the day
- Bucket material retention has been improved by providing a 15 degree increase in bucket rollback to reduce material spillage Curved side cutters and integrated spill guards improve bucket fill rates
