Project Ideas

Business

Quiet-Hour, Battery-Powered Mowing

Offer early-morning and HOA-friendly mowing using the brushless, low-noise mower with no fumes. Market it to schools, medical offices, and noise-sensitive neighborhoods. Plan routes around the ~60-minute runtime and carry spare batteries for continuous service.


Lawn Art and Event Branding

Create custom stripes, patterns, and simple logo silhouettes with varied cut heights and mowing directions for events, open houses, and youth sports. Deliver before-and-after photos or drone shots as a premium add-on. Mulch or bag based on the client’s finish preference.


Realtor Curb-Ready Package

Provide rapid, on-call pre-listing lawn refreshes: mow, bag clippings, and tidy edges (with separate tools) for a photo-ready yard. Battery power avoids gas spills and odors at showings, and the folding, vertical storage design makes transport in compact vehicles easy.


Leaf-to-Mulch Fall Service

Use the mower’s mulching mode to shred leaves into fine particles that feed the lawn, then do a final bagging pass for a clean look if desired. Package it as a soil-building, eco-friendly fall cleanup. Upsell seasonal subscriptions for recurring visits.


Grass-Cycling and Compost Subscription

Offer two tiers: mulching-only to return nutrients or bag-and-compost with monthly delivery of finished compost made from clients’ own clippings. The 3-in-1 deck switches fast between modes, and vertical storage saves cargo space for a compact, mobile operation.

Creative

Lawn Labyrinth Weekend Build

Lay out a simple maze and use the dual-lever height adjustment to create contrasting path and wall heights (e.g., 1.75 in. paths with 3.5 in. borders). The 21-1/2 in. deck naturally sizes the pathways, and the auto-sensing RPM helps power through thicker sections. Side discharge can lightly outline edges; refresh weekly as it grows.


Living Lawn Pixel Art Mural

Grid the yard into 21-1/2 in. squares and mow alternating heights and directions to create shaded patterns or simple images. Use mulching for “darker” blocks and bagging for “lighter” ones to fine-tune contrast. Update the mural every few days to keep lines crisp.


Backyard Putting Green and Fringe

Select a small area and gradually lower the cutting height over several weeks to establish a mini putting surface, keeping a higher ‘fringe’ around it. Mulch clippings to feed the turf, then switch to bagging when thatch builds up. The self-propelled FWD makes the repeated precision passes easy.


Mini-Meadow with Meandering Paths

Let a biodiversity patch grow higher while maintaining 1–2 mower-width trails through it. Set the meadow areas to 4 in. and the paths to 2 in. to create visual depth and habitat. Auto-sensing RPM keeps the mower steady through denser growth.


Compost Gold Loop

Bag clippings to build a hot compost pile layered with fall leaves, then use the finished compost to top-dress lawns and garden beds. Side discharge first to windrow leaves for quick pickup, then bag to tidy. Track cut heights to balance nutrient input throughout the season.
