Quick Answer: Cub Cadet does build robotic mowers, but the one sold in the US isn’t for home lawns — it’s the RG3/RGX, a commercial “Robotic Greens Mower” for golf-course putting greens (~550 lbs, 22-inch cut, 48V lead-acid battery). Cub Cadet’s actual residential robot mower, the XR3 (up to 1 acre on the XR3 5000, boundary-wire with a rain sensor), is real and currently sold — just only through cubcadet.ca (Canada) and cubcadet.eu (Europe), not cubcadet.com. Cub Cadet is owned by the same MTD Products / Stanley Black & Decker parent as Robomow, which does sell a boundary-wire robot mower in the US.
If you searched “Cub Cadet robot mower” because you’ve mowed with a Cub Cadet zero-turn or seen the brand at Home Depot and wondered if they’d made the jump to autonomy, the honest answer has two halves: yes for commercial turf, and yes-but-not-here for a home lawn.
The US robotic product: RG3/RGX, and it’s not for your yard
Cub Cadet’s only robotic mower currently listed on its US site, cubcadet.com, is the RG3 — officially a “Robotic Greens Mower.” This is golf-course maintenance equipment: a 22-inch cutting width, a multi-roller chassis built for the tight, precise cut a putting green needs, four 12V 80Ah rechargeable batteries on a 48V system, roughly 550 lbs, and 3–4 hours of mowing per 4–5-hour charge. It’s genuinely operator-free and can mow in the dark, per Cub Cadet’s own product page — but it’s built and priced for golf courses and sports turf, not a suburban backyard. A related model, the RGX, appears on the same US site marked “Coming Soon,” with no public pricing for either machine — Cub Cadet routes both toward a dealer locator rather than a checkout.
The residential robot mower exists — just not on cubcadet.com
Cub Cadet does make a home-lawn robot mower called the XR3, in three sizes: the XR3 3000 (up to 1/3 acre), XR3 4000 (up to 2/3 acre), and XR3 5000 (up to 1 acre), each with smartphone control and a rain sensor that sends the mower back to its dock in poor weather. The catch is availability — the XR3 lineup lives on cubcadet.ca and cubcadet.eu, and Cub Cadet’s US lawn-mowers page (cubcadet.com/en_US/lawn-mowers) lists exactly three categories — zero-turn, riding, and walk-behind — with no robotics tab at all. If you’re shopping from a US address, the XR3 you may have seen referenced online simply isn’t a product Cub Cadet sells to you.
| Model | Type | Coverage | Navigation | Sold in US? |
|---|---|---|---|---|
| RG3 | Commercial greens mower | Golf greens (not acreage-rated) | Autonomous, boundary-defined | Yes — dealer only |
| RGX | Commercial greens mower | Golf greens (not acreage-rated) | Autonomous, boundary-defined | "Coming Soon" — no price |
| XR3 3000 | Residential | Up to 1/3 acre | Boundary wire + app | No — Canada/EU only |
| XR3 4000 | Residential | Up to 2/3 acre | Boundary wire + app | No — Canada/EU only |
| XR3 5000 | Residential | Up to 1 acre | Boundary wire + app | No — Canada/EU only |
Why Robomow is the closer US answer than it looks
Here’s the part that makes Cub Cadet’s story different from a brand that simply doesn’t make a home robot mower: Cub Cadet already has a US-market sibling that does. MTD Products acquired Robomow (then Friendly Robotics) in 2017, and Stanley Black & Decker completed its acquisition of MTD Holdings in 2021 — the same parent company that owns Cub Cadet and Craftsman now owns Robomow too. So a Cub Cadet shopper who wants a boundary-wire robot mower actually sold and supported in the US isn’t out of luck within the family — they just need to buy it under the Robomow badge instead. Robomow’s US lineup runs from the entry-level RX20 (up to 1/20 acre, $799.99 at Home Depot) to the RS630 (up to 3/4 acre, a 22-inch dual-blade deck — one of the widest residential cuts around, $2,499.00 at Home Depot).

If wire-free navigation matters more to you than staying inside one corporate family, the current wire-free field — Segway Navimow, Mammotion Luba/Yuka, and Husqvarna’s iQ series — all skip the buried-wire install Robomow and the XR3 both still require. Start with our best robot lawn mower pillar, or see robot lawn mower without perimeter wire if skipping the wire is the whole point.
Cub Cadet robotics by the numbers
- 550 lbs: Approximate weight of the RG3 commercial greens mower — a scale built for golf-course maintenance crews, not a homeowner’s garage.
- 1 acre: Maximum coverage of the XR3 5000, Cub Cadet’s largest residential robot mower — sold in Canada and Europe, not the US.
- 2017 → 2021: The acquisition chain that put Robomow — the US-available, boundary-wire robot mower actually related to Cub Cadet — under the same Stanley Black & Decker roof.
- 0: Robotic mowers listed for home lawns on cubcadet.com as of this writing.
The bottom line
Cub Cadet’s robot-mower story splits cleanly in two: a commercial golf-greens machine (RG3/RGX) that is sold in the US but was never built for a home lawn, and a genuine residential robot mower (XR3) that was built for a home lawn but was never brought to the US. If you want to stay in the Cub Cadet corporate family and buy something today, Robomow — a sibling brand since the 2021 Stanley Black & Decker/MTD merger — is the real answer, not an XR3 import. Cub Cadet joins a growing list of familiar power-equipment names with an unexpectedly complicated robot-mower story: RYOBI makes none at all, John Deere’s home robot was discontinued years ago, Honda’s Miimo is real but dealer-only, Bosch’s Indego and Ambrogio both ship — just never officially to the US — and now Cub Cadet rounds out the list as the one brand whose US-sold robot and home-market robot are two entirely different machines.
