Specifications
Features
Pros
- ✓No DPF and no DEF on the 74 hp Kohler KDI means zero regen downtime - owners coming from regen-plagued machines call this the main reason they bought it.
- ✓The 4-year/4,000-hour Kohler engine warranty plus 2-year/2,000-hour machine coverage is about the strongest paper protection in the segment.
- ✓The 2024 uni-body redesign stiffened the frame and improved service access dramatically, with a tilting cab and large rear door.
- ✓A 3,100 lb rated capacity and 6,200 lb tipping load put it squarely in the heart of the mid-frame class where most buyers shop.
- ✓Vertical lift and a 128-inch hinge pin height load dump trucks cleanly for a machine this size.
- ✓Buyers can choose H-pattern or ISO joystick pilot controls, a flexibility traditionalists appreciate.
- ✓Designed and assembled in Wisconsin, with the engineering focus on mechanical simplicity over electronic complexity.
- ✓Aggressive pricing and frequent promotional financing make it one of the better value plays among 74 hp verticals.
Cons
- ✗The thin US dealer network remains the biggest knock - great machine, but support depends heavily on your zip code.
- ✗Resale lags Bobcat, Cat, and Kubota noticeably, so total cost of ownership math needs honest trade-in assumptions.
- ✗Standard 20.1 gpm aux flow is average, and the 30.1 gpm high-flow option tops out below what dedicated mulching outfits want.
- ✗Brand awareness is low among US buyers, which can complicate insurance, financing, and eventual private-party sale.
- ✗The uni-body generation is new enough that high-hour durability reports are scarce.
- ✗Cab noise levels are acceptable but behind the best-in-class pressurized cabs.
- ✗Limited factory tech options - no grade control, camera packages are basic, and telematics is less developed than the majors.
- ✗Parts are domestically sourced but stocked in fewer depots, so less-common components can take days to arrive.
