No Mow Zones and Pollinator Strips for Robot Mowers

How does a no mow zone stay out of the route?

A pollinator strip or no mow zone stays out of a robot mower's route only when it exists in the mower's world as a closed shape the machine is told to avoid. The mower does not know that a patch of milkweed or clover matters. It knows the lines you gave it, and it follows those lines on every pass.

The work has three parts: draw the zone, check the boundary after setup, and explain the lines to the client so nobody sends a crew into the strip by hand. The middle step gets skipped most often, and it is where most surprises turn up.

Wired systems: placing the boundary wire

On a wired system, the zone is built into the perimeter. Makita's manual for its RM350D model describes laying the wire around the outermost edge of the work area and leaving loops slightly long so they can be adjusted later. The same manual says to keep the mower less than 35 m from the nearest boundary wire. That figure belongs to that model, so read the manual for the unit you install.

Husqvarna's support material describes no go areas as islands inside the boundary wire. Its stay out zone guidance says to run as long a section of wire as possible, so the mower has room to steer around the zone. Short wire sections leave little room for a clean turn before the mower reaches the strip.

Wire free systems: drawing zones on the map

Wire free mowers, which position themselves with satellite, LiDAR or camera systems, set zones in an app. Anker describes two mapping paths: you steer the mower around the lawn boundary yourself, or the mower maps the lawn on its own. Its advice is to treat the first map as a draft and watch a few runs before you finalize it.

Husqvarna says app based stay out zones can go almost anywhere except over the charging station or the guide wire. Common candidates include drop offs, shrub beds, trees, water features, playsets and newly seeded grass. Draw each one at its real edge, not at an estimate you plan to fix later.

Worx takes a different route with its Off Limits option. A magnetic strip laid in a closed loop defines the no mow area with no boundary wire. As of November 2026, Worx's documentation says its Cut To Edge function does not work around the strip. If the client wants a crisp mowed line right beside a pollinator planting, settle that before install.

Checking the boundary after setup

Do not accept the first map on faith. Walk the full perimeter with the mower stopped, compare each drawn zone to the physical edge, and then watch complete runs. A map can look right on a phone and still send the mower a few inches closer to a strip than you intended.

Write down what you found at each check. A dated note turns a vague complaint from the client into a specific fix.

• Walk each zone edge against the map outline, paying extra attention where the mower turns.
• Watch several full passes and note every angle at which the mower meets the strip.
• On a wired system, if the mower enters the wrong area, inspect the boundary wire first, because wire spacing, edge distance and peg spacing vary by model.
• Recheck after bed edging, new planting, tree work or any wire repair.

Hazards that need zones even without plants

Toro's help article defines exclusion zones as areas inside a mowing zone that the mower is told not to cut. It warns that leaving out exclusion zones for pools or retaining walls could let the mower fall, be damaged, or contact unintended objects. Toro also states that its cameras are not an object detection system.

A zone drawn around a pollinator strip is therefore a boundary for the cutting path, not a safety net. Pools, retaining walls, steep drops and playset footings need their own exclusion zones, and the crew still walks those edges on arrival.

Mowing height and the edge beside the strip

Colorado State Extension advises raising the mower to 3.5 inches, or 4 inches if the mower allows, and mowing often enough that no more than one third of the grass height comes off at a time. A robot runs often, so it will keep cutting the lawn beside the strip on that schedule. Set the agreed height and confirm it on the first visit.

Colorado State also notes that a mowed edge shows the tall area is intentional rather than neglected. I did not find a source in this run on cutting that edge along a strip with a robotic mower, so set it with the crew and check it at the first visit.

Husqvarna's rewilding mode, as described by one consumer news site, maps the lawn with GPS and sets aside about 10 percent by default, which the homeowner can move or enlarge. That is a vendor reported feature, so confirm the setting on the model you install. The same article notes that an unmown patch in a recently planted or typical lawn may mostly grow dandelions and clover rather than pollinator plants. That is commentary, not a controlled study.

Explaining the lines to a client

Clients usually worry about two things: that the mower will cut the strip, and that the strip will look neglected. Show them the map with each zone shaded, then show a short clip or the run log from a few passes. Say plainly that the zone is an instruction the mower follows, and that the crew checks it on site.

Give them a short written note they can share with neighbors or a board: which areas are excluded, what height the rest is cut at, and who to call if the mower gets too close to a planting. A note like that answers most questions before they reach you.

This is where Service Robot Co. fits in. We are OEM neutral, so we pick the mower that suits the site rather than a single brand, then map, integrate and train on the site with the client. We lease robots through financing on a three year lease, with one fixed lease payment quoted after a site assessment, and each unit is serviced under RoboCare by regional service engineers in every state we service.
