A designated mowing zone separate from the primary area where the charging dock is located. The mower must either navigate a corridor or be manually transported to reach the secondary area. Most premium mowers support 2–10 separate zones within a single mapping system.
The Three Approaches to Multi-Zone Mowing
Approach 1: Corridor Connection (Fully Automated)
If a physical path exists between the front and back yards (a side yard, driveway gap, or open fence gate), map it as a transit corridor. The mower drives through the corridor autonomously to reach the secondary zone, mows it, then returns through the corridor to the dock.
Requirements: Corridor must be at least 60cm wide and free of obstacles. The mower needs RTK or LiDAR signal throughout the corridor.
Best for: Yards with side access between front and back that is wide enough for the mower.
Approach 2: Manual Carry (Simple, No Setup)
Physically pick up the mower, carry it to the front yard, place it down, and tap "Start" in the app for the secondary zone. The mower will mow the mapped zone, then stop. You carry it back to the dock to charge.
Requirements: The secondary zone must be pre-mapped (walk the boundary once). Battery should be at 80%+ before starting.
Best for: Small front yards (<2,000 sq ft) where the mow time is under 30 minutes.
Approach 3: Extended Base Station Coverage
If the RTK base station is mounted high enough (roof peak, 3m+ pole), it may cover both front and back yards. Walk the mower to the front yard with the app open and check: (1) satellite count (need 12+), (2) RTK Fix status (not Float), and (3) positional accuracy indicator.
Requirements: Base station with clear sky view that covers both zones. Front yard must be within RTK correction range (typically 500m for consumer units).
Best for: Properties where the base station is centrally located or elevated with line of sight to both zones.
Battery Management for Secondary Zones
Battery management is the critical constraint when mowing secondary zones. The mower must have enough charge to: (1) transit to the secondary zone, (2) complete the mow, and (3) return to the dock.
| Secondary Zone Size | Estimated Mow Time | Transit Overhead | Min. Battery at Start |
|---|---|---|---|
| Under 1,000 sq ft | 15–25 min | 5–10% | 50% |
| 1,000–2,500 sq ft | 25–45 min | 5–10% | 65% |
| 2,500–5,000 sq ft | 45–90 min | 10–15% | 85% |
| Over 5,000 sq ft | 90+ min (may need 2 charges) | 10–15% | 100% + mid-mow return |
Scheduling Strategy
The optimal scheduling approach for multi-zone properties:
- Primary zone (back yard): Daily mowing at the standard schedule.
- Secondary zone (front yard): 2–3 times per week, scheduled on alternating days.
- Allow a full charge cycle between zones. If the mower finishes the back yard at 30% battery, let it charge to 100% before sending it to the front yard.
- Schedule the secondary zone for the time of day with the best conditions — typically mid-morning when dew has dried and GPS signal is strong.
When You Actually Need a Second Base Station
A second base station ($200–$500) is justified only when:
- The primary base station has no line of sight to the secondary zone (house blocks the signal entirely).
- The secondary zone is very large (>5,000 sq ft) and requires precision that RTK Float mode cannot provide.
- The secondary zone is more than 100m from the base station and signal quality drops below usable levels.
For most residential properties with front + back yard configurations, a single elevated base station and the corridor or manual carry method is sufficient.
Frequently Asked Questions
Yes, if the mower supports "Secondary Area" or "Multi-Zone" mode. You map both areas separately, then either configure a corridor between them or manually carry the mower to the second zone. Most premium mowers support this out of the box.
Only if the front yard has no line of sight to the rear-mounted base station. If the base station is elevated (roof mount), it often covers both front and back yards. Test this by walking the mower to the front yard and checking satellite count and RTK Fix status in the app.
Transit from dock to a secondary area typically consumes 5–15% battery depending on distance. Plan for the secondary zone to require 15–20% less mowing time than its area would suggest, to ensure the mower has enough battery to return to the dock.
Yes. Most premium mowers allow per-zone scheduling — Monday/Wednesday/Friday for the back yard, Tuesday/Thursday for the front yard. Some models also allow different cutting heights per zone.
If the mower cannot return to the dock, it will stop and send an alert via the app. You will need to physically carry it back to the charging station. To prevent this, ensure at least 30% battery before starting the secondary zone and set the "return to dock" threshold to 20%.
