What owners say about each
Wacker Neuson ST37
- A 3,700 lb rated capacity from a 74 hp machine is excellent work-per-horsepower, and the 7,400 lb tipping load keeps it planted with heavy pallets.
- Ground pressure of 4.3 psi is the best in the ST line, floating over soft turf and mud that ruts standard mid-frames.
- The Kohler KDI's no-DPF, no-DEF Tier 4 solution eliminates regens entirely - a simplicity argument that resonates with high-hour users.
- Kohler's 4-year/4,000-hour engine warranty plus the 2-year/2,000-hour machine warranty leads the class on coverage.
- Standard 23 gpm aux flow is strong for the class, with a 33.1 gpm high-flow option that handles mid-size mulchers.
- Vertical lift and a 128-inch hinge pin height make truck loading a one-motion affair.
- It undercuts comparable Bobcat T76 and Cat 265 configurations on price by a meaningful margin.
- Dealer coverage is the perennial Wacker Neuson issue - buyers far from a dealer are effectively self-supporting.
- The model launched in 2024, so there's almost no long-term field history at high hours.
- The same 74 hp engine that feels strong in the ST27 works harder in this 9,000 lb frame, and operators notice on sustained mulching or hills.
- Wide tracks that help flotation make it wider than some site gates allow, and replacement rubber costs more.
- No 100 hp option in the uni-body generation yet, so power-hungry buyers must jump to the older-design ST50.
- Fewer rental units in circulation means limited chances to demo before committing.
- Basic telematics and no factory grade-control integration keep it behind the tech curve for GPS-heavy contractors.
Wacker Neuson ST45
- A 4,500 lb rated operating capacity and 9,000 lb tipping load put it in genuine large-frame territory - it forklifts pallets of sod and block that mid-frames refuse.
- The 134.8-inch hinge pin height is one of the taller lift heights in the class, clearing high-sided dump trucks and hoppers with ease.
- The 74.3 hp Kohler KDI needs no DPF and no DEF, so a big machine stays refreshingly simple to run and maintain.
- Kohler's 4-year/4,000-hour engine warranty on top of 2-year/2,000-hour machine coverage means the expensive bits are covered longest.
- This platform has been in production longer than the uni-body models, so it has more accumulated field hours and known reliability.
- It typically prices well below 100 hp flagship rivals while lifting just as much.
- With only 74.3 hp moving a 10,267 lb machine, it's tuned for lifting rather than aggressive dozing - operators who push hard wish for the ST50's extra power.
- Standard 22.1 gpm auxiliary flow is modest for a large frame, and even the 31.4 gpm high-flow option is midpack.
- The Series-II design predates the uni-body machines, so service access and cab refinement feel a generation older.
- Resale values trail the big four brands by a wider dollar margin at this price point.
- At over 10,000 lbs it needs heavy trailer capacity, a cost some step-up buyers underestimate.
- Limited factory tech - no grade control and basic displays - for contractors accustomed to flagship-level electronics.
- Brand-name attachment packages and dealer-installed options are fewer than what Bobcat or Cat dealers can spec.
