GDU Calculator vs John Deere Connect Mobile

The Ag PhD GDU Calculator is a reference for corn and wheat growers to determine the amount of Growing Degree Units for their crops in the current crop season. Includes day-by-day breakdown of temperature and GDU data and has the option for push notifications informing growers of potential problems in their fields based on their crop growth stage, as calculated by the crop GDU from planting date.

John Deere Connect Mobile is a mobile application downloaded onto an iPad to monitor, optimize, and ensure high quality operations; and the best job possible. The Connect Mobile app connects to the machine through a WiFi network to document and display quality, productivity, and agronomic data about the operation. The app works in conjunction with either the GreenStar™ 3 2630, Generation 4 4600 & 4640 CommandCenter™ displays, & Generation 5 displays. The John Deere Connect Mobile app can be used for planting, spraying, and harvesting operations; and requires no additional hardware with MY18 and newer Connect Mobile ready machines. Other equipment can be fitted with Connect Mobile with an additional field kit. Contact your dealer for details.
