Commercial Utility Stance
UMAX gives crews a work-focused Yamaha platform for grounds support, facility movement, event setup, and utility runs.
Yamaha commercial utility
The UMAX is Yamaha's commercial work cart for properties that need more than passenger movement. It brings a substantial cargo bed, bucket seats, under-hood storage, large 20-inch tires, and the utility to handle course, campus, resort, facility, and grounds work.
Cart Mart can help match the powertrain, cargo setup, charger, bed protection, hitch use, service plan, and parts support to the work the vehicle needs to perform.
Utility work, Yamaha scale
The UMAX is built around useful work: an 800-lb cargo-bed rating, 1,500-lb towing capacity, 41.1-inch by 45.9-inch bed size, and a tilt bed that makes unloading quicker.
Choose EFI for quick refueling and familiar gas operation, AC for proven electric utility, or Li for lithium convenience and reduced routine battery care.
Work views

UMAX gives crews a work-focused Yamaha platform for grounds support, facility movement, event setup, and utility runs.

The cargo bed and receiver hitch make the cart useful for tools, parts, towels, coolers, maintenance supplies, and the jobs that never fit neatly into one category.

The UMAX bed is the center of the build, with enough practical room for daily property work without stepping into a much larger vehicle class.

Bucket seats, dash storage, top coverage, and Yamaha ride quality keep the utility side from feeling rough for the crew using it all day.

Use it where a compact utility vehicle makes more sense than a full truck: golf courses, resorts, campuses, parks, event venues, and large private properties.
Gas and electric choices

The EFI gas powertrain pairs a Yamaha-built 402cc engine with 45 mpg efficiency, easy engine access, and familiar refueling for demanding daily utility work.

The AC powertrain gives UMAX a lower-maintenance electric path with Trojan batteries, Toyota motor control, a Delta-Q charger, and steady work-cart performance.

The Li powertrain brings lithium-ion performance, efficient charging, and no-watering battery care for properties that want electric utility with less routine battery maintenance.
Innovative features

A sizable under-hood storage area gives crews another place for small items that should not bounce around in the bed.

The bed mat helps protect the cargo area, slows wear, reduces noise, and makes hauling rougher materials feel less punishing.

The dump bed carries up to 800 lbs and 12.9 cubic feet, giving UMAX the utility backbone that separates it from a passenger cart.

The dash supports professional daily use with cup holders, a fuel or battery gauge, and optional USB charging.

The suntop helps protect crews from the elements during long workdays around the property.

The side-fill gas tank makes refill stops quicker and cleaner on EFI builds.

The standard receiver hitch supports up to 1,500 lbs of towing capacity, extending UMAX utility beyond the cargo bed.

The tilt bed helps crews unload quickly instead of lifting every load out by hand.
