Quick take: The Wacker Neuson ST37 costs $8,000 less; the Wacker Neuson ST45 has a higher rated operating capacity (4,500 vs 3,700 lbs).

✓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.
✓The uni-body frame and tilt-up cab make daily checks and major service faster than most competitors.
✓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.
✗Resale discount versus the majors applies here too, and bigger machines feel it more in dollar terms.
✗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.

✓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.
✓The cab is roomy with good sightlines to the bucket edge, and controls are available in H-pattern or ISO joystick.
✓Self-leveling and ride-control features are available to protect palletized loads over rough ground.
✓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.
✗Wacker Neuson's sparse dealer network is riskiest on a large frame that working crews depend on daily.
✗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.
