X4 Series Frequently Asked Questions
Technical operational guidance answers relating directly to premium residential fusion tracking mechanics.
The X4 range features a 4WD driving engine with dual independent steering motors. This configuration allows the machine to scale steep slopes and rolling banks up to 84% (40°) without losing traction or damaging the lawn.
No external antenna installation is required. Thanks to EFLS™ Dual-fusion (combining Network RTK and 360° Vision), the mower maps boundaries automatically using GeoSketch™ technology and navigates accurately even near deep architectural overhangs or tree cover.
Every X4 model includes Connect+ (Cellular connection) free for 1 year (renewable annually for around £29). This enables live GPS anti-theft tracking, out-of-boundary alarms, remote app controls, and OTA updates anywhere via Bluetooth, Wi-Fi, and cellular networks.
