Built-in Map Editor terrain tools, Test Drive button, and Steam Workshop sharing
Select an editor tool module below to inspect its terrain brush behavior, mower hazard impact, and Test Drive rules.
Paint mowable turf zones alongside sand bunkers, dirt patches, and paved walkways to define where crews must cut and where rakes or trimmers are needed.
Complete technical manual for the built-in One More Lawn Map Editor and Steam Workshop integration (unlocking in the November 12, 2026 full game release). Paint grass, sand, dirt, and stone paths, dig water hazard ponds, raise hills, place fences, trees, and up to 47 garden gnomes, click Test Drive to jump straight onto the riding mower, and publish custom contracts for 6-player co-op.
Every tool in the One More Lawn Map Editor connects directly to the game's physical mowing, trimming, and water-hazard systems. When you paint mowable grass, sculpt steep hills, or dig deep water ponds, the custom contract inherits the exact same blade-height detection, wagon-towing physics, and engine-flooding rules used on official jobs like Julio's Country House, Rubén's Golf Course, and Marcela's Island.

Start with a blank plot and use the terrain brushes to paint thick mowable grass, golf-style sand bunkers, dirt borders, and stone walkways. Mixing narrow turf corridors with wide open lawns gives both the Riding Mower and handheld String Trimmer clear roles in co-op, while paved walkways and dirt service roads provide high-traction lanes for hauling linked Dump Wagons back to the trash container.
Use the elevation brush to raise hills or carve sunken basins filled with water. Just like Marcela's Island and Rubén's golf course pond, deep water in custom maps will drown the riding mower engine if a driver slides off the bank. Steep hills also challenge three-speed manual gear control and steering wheel setups when towing heavy grass bag loads.
Place perimeter fences and trees to force precision edging, then populate the lawn with ceramic garden gnomes—up to 47 gnomes as highlighted on the official Steam store page—so crews must either steer with surgical precision or relocate gnomes by hand before engaging the mower deck blades.
Hit the Test Drive button inside the editor at any time to drop directly onto the riding mower seat, turn the ignition key, and test your sightlines, fence clearances, and slope gradients in real time. Once every turf zone and obstacle feels right, publish the lawn to Steam Workshop so solo players or 6-player online co-op lobbies can subscribe and mow your creation together.
