Independently developed by eSurvey, the eSurvey EAS301 Pro is an electric wheel-based auto-steering system.

EAS301 Pro could transfer farm work from fully manual driving to semi-automatic operation. It means high time efficiency and less operator fatigue. Based on the route planning algorithm, the vehicle could go through the same paths every time to seed, spray and harvest with ±2.5cm accuracy, which increases crop yield and reduces chemical usage.

Selling point 1

All-purpose System: Suitable for Various Types of Agricultural Machinery

Able to apply it to multiple types of agricultural machinery, including tractor, transplanter, sprayer, harvester, etc., to make your farm work more effectively.

Selling point 2

Easy Installation: No Need to Change Hydraulic Circuit

Quickly install it on or remove it from your agricultural machinery as fast as 15 minutes, allowing you to quickly remove it from one agricultural machinery and install it on another.

Selling point 3

Free from Terrain Worries

No longer need to worry about rough terrains, supported by our T3 terrain compensation technology that is used to minimize skips and overlaps between each pass when working on rough and sloping fields.

Selling point 4

High Control Accuracy with Multiple Guidance Lines

Enable ±2.5 cm control accuracy even when the vehicle speed is as low as 0.2km/h, and no longer need to worry about fine planting vegetables and fruit crops.

Selling point 5

24-hour Uninterrupted Work

Continuously work even in the day with strong lights or at night. Free RTK keep function could maintain centimeter accuracy for 600 seconds when EAS301 lost correction data.

Selling point 6

Optional Dual Camera

Support a maximum of two 720P video outputs for monitoring implement and environment.
