Pros & cons
Kress Mission RTKn KR173
- ✓Cheapest Kress with OAS obstacle avoidance, so it steers around objects rather than bumping them
- ✓No antenna, base station or wire; dealer install and app boundary
- ✓Parallel stripes with dead-reckoning fallback under trees and beside the house
- ✓1.2 acre maximum on a 72-hour cycle gives headroom over the 0.7 acre recommendation
- ✓Quiet 59 dB, 27.6 lb, electric height adjustment and a floating deck against scalping
- ✗Only works where a Kress dealer antenna covers your address; no coverage, no mower
- ✗Runtime, charge time, OAS sensor type and warranty term are not published on the US page
- ✗Same 7.9 in deck and 4 Ah pack as the cheaper KR172, so coverage growth comes from longer cycles, not more mower
Kress Mission RTKn KR172
- ✓No antenna, base station or wire to install; boundary is drawn in the app
- ✓Straight parallel stripes with dead-reckoning fallback when satellites are blocked
- ✓Quiet 59 dB and light 26.5 lb body with electric height adjustment
- ✓4G, GPS theft tracking and OTA updates included; dealer handles setup and service
- ✗Only works where a Kress dealer antenna covers your address; coverage must be verified first
- ✗No camera obstacle avoidance on this trim, so it relies on bumper contact and no-go zones
- ✗Runtime, charge time and warranty term are not published on the US product page
- ✗Small 8 in deck and 0.5 acre recommendation make it a modest-lawn machine at $1,700
- ✗No US retailer reviews yet; dealer-only sales mean little independent owner feedback
