2025 Wacker Neuson ET42 4-Ton Compact Excavator For Sale — Sequim, WA & Olympic Peninsula

The 2025 Wacker Neuson ET42 is an advanced 4-ton class conventional tail-swing compact mini excavator engineered for site-prep contractors, septic installers, utility crews, commercial landscapers, and rural acreage managers who require heavy lifting stability, deep digging reach, and cycle speed. Available now at Leitz Farm Supply & Equipment Sales in Sequim, Washington, this 43.6 HP production-class excavator bridges the gap between smaller residential mini diggers and larger 5-to-6-ton machines. Powered by a turbocharged Perkins 403J-E17T Tier 4 Final diesel engine, the ET42 combines an operating weight ranging from 8,889 to 10,161 lbs with a maximum digging depth of up to 11 feet 8 inches (139.6 in.) and an industry-leading bucket breakout force of 9,846 lbf.

While zero-tail-swing excavators compromise on rear counterweight balance to stay within their tracks, the conventional tail-swing architecture of the Wacker Neuson ET42 keeps the machine planted when lifting heavy concrete catch basins, setting trench boxes, or craning wet hemlock and cedar logs over the side. For excavation professionals throughout Clallam and Jefferson counties, this added counter-balance directly translates into superior stability on wet slopes and off-camber terrain. Whether you are cutting foundation footings in Port Angeles, installing pressurized septic drain fields in Sequim, trenching power conduits in Forks, or clearing pasture ditches in Chimacum, the ET42 provides smooth load-sensing hydraulics and rapid cycle times. Every unit at Leitz Farm Supply includes a full pre-delivery inspection (PDI), filled fluids, and complete warranty and parts backing from our certified Sequim dealership.

Heavy-Duty Engineering, Hydraulic Power & Digging Reach

• 43.6 HP Turbocharged Perkins Diesel (Tier 4 Final): The Perkins 403J-E17T liquid-cooled turbo diesel provides strong low-end torque and immediate hydraulic response without complex, high-maintenance emissions systems.

• Conventional Tail-Swing Stability: By placing deliberate counterweight over the rear undercarriage, the ET42 delivers superior over-the-side craning and lifting charts compared to zero-tail competitors. This allows operators to swing full buckets of heavy clay and rock over truck sideboards without chassis tipping or cab rocking.

• 11' 8" Dig Depth with 200° Bucket Kinematics: With a maximum digging depth of 139.6 inches and an extended reach at ground level over 18 feet, the ET42 handles deep sewer taps and foundation cuts with fewer repositioning stops. Wacker Neuson's 200-degree bucket rotation provides vertical wall digging and bucket cleanout angles.

• Advanced Load-Sensing Hydraulic System: Delivering up to 23.7 GPM of auxiliary hydraulic flow at 3,553 PSI, the load-sensing system automatically adjusts pump displacement to match operator demand. Dual-direction auxiliary hydraulics with in-cab continuous-flow detents allow operation of hydraulic thumbs, high-output augers, plate compactors, and concrete breakers.

• In-Cab ISO/SAE Pattern Changeover: Switch between excavator (ISO) and backhoe (SAE) control patterns instantly via an electronic selector, ensuring any operator on the crew can step in without re-routing hydraulic hoses.

Key Technical Specifications

Real-World Jobsite Applications

• Septic System Installation & Drain Fields: Sizing septic tanks and digging gravity or pressure drain fields on the Olympic Peninsula requires exact depths and stability. The ET42's 11' 8" dig depth easily sets 1,000-to-1,500-gallon concrete tanks, while the 200° bucket linkage digs straight trench walls.

• Site Preparation, Footings & Foundations: Digging footings through packed Pacific Northwest glacial till, hardpan, and basalt rock demands heavy breakout force. With nearly 10,000 lbs of bucket breakout, the ET42 breaks ground without stalling the pump.

• Retaining Walls & Bolder Placement: Paired with a hydraulic thumb, the conventional tail-swing counterweight enables safe handling of 2-man and 3-man landscape boulders and ecology blocks without the rear tracks bouncing off the ground.

• Land Clearing, Brush Removal & Stump Extraction: Digging out stubborn vine maple, scotch broom, and saturated fir root balls requires root-snapping arm tearout force. The ET42 cuts beneath root crowns, and the thumb linkage lets you shake dirt clean before loading.

• Underground Utility Trenching (Water, Power & Sewer): Fast cycle times allow operators to open up hundreds of linear feet of utility trench per day. The standard backfill dozer blade with float makes rough grading and trench restoration quick.

Olympic Peninsula & Western Washington Relevance

Operating excavation equipment west of the Cascades brings challenging soil conditions: wet marine clay, dense glacial till, heavy river rock, and steep coastal foothill grades.

• Sequim & Dungeness Valley: Ideal for equestrian ditch maintenance, irrigation canal repair, and acreage utility hookups across dry-belt parcels where tight grading precision is required.

• Port Angeles & Foothill Ridges: Provides the gradeability and craning power necessary to terrace steep residential home sites, dig foundation steps, and clear storm blowdowns on rough timber parcels.

• Forks & The West End: The high annual rainfall out west turns soil into soft muck. The ET42’s 13.8-inch rubber tracks distribute machine weight to maintain traction, while the sealed track rollers keep abrasive slurry out of the undercarriage.

• Port Townsend, Chimacum & East Jefferson County: The perfect size for small-farm drainage management, culvert replacement, pole barn site prep, and estate infrastructure projects.

Competitor Comparisons: 4-Ton Class Mini Excavators

Excavation contractors cross-shopping the 4-ton mini excavator market routinely evaluate the Kubota KX040-4, Bobcat E42 / E45, Caterpillar 304 / 304.5, and John Deere 35G / 50G:

• Versus Kubota KX040-4: The Wacker Neuson ET42 delivers 43.6 gross horsepower compared to the Kubota KX040’s 40.4 HP, providing higher hydraulic auxiliary flow (23.7 GPM vs. 17.1 GPM) for faster operation of hydraulic breakers, thumbs, and augers.

• Versus Bobcat E42 (Zero Tail Swing): While zero tail swing has advantages in tight alleyways, it sacrifices over-the-side lifting capacity. The conventional tail swing ET42 provides far greater craning stability when swinging heavy rock or pipe across the tracks on uneven ground.

• Versus John Deere 35G: The ET42 sits in a heavier weight bracket (up to 10,161 lbs vs. ~7,760 lbs), giving you significantly more tractive pushing effort on the dozer blade and nearly 3,000 lbs more bucket breakout force for tough digging.

• Versus Caterpillar 304: The ET42 features Wacker Neuson’s 200-degree bucket rotation linkage, allowing vertical trench wall digging and better material retention at maximum lift height than standard commercial linkages.

Frequently Asked Questions

Does the 2025 Wacker Neuson ET42 require Diesel Exhaust Fluid (DEF)?

No. The 43.6 HP Perkins 403J-E17T turbo diesel meets EPA Tier 4 Final emissions standards without requiring Diesel Exhaust Fluid (DEF). This eliminates DEF handling, tank freezing risks during winter freezes, and costly DEF dosing sensors.

What is the maximum digging depth of the Wacker Neuson ET42?

The ET42 has a maximum dig depth of 11 feet 8 inches (139.6 inches) and an outreach at ground level of over 18 feet, allowing deep utility and septic installations with fewer repositioning moves.

What is the breakout force on the ET42?

The ET42 produces an industry-leading 9,846 lbf of bucket breakout force and 6,722 lbf of arm digging/tearout force, making it capable of tearing through dense glacial hardpan, packed gravel, and heavy tree roots.

Can I run a hydraulic thumb and an auxiliary tool like an auger or breaker?

Yes. The ET42's hydraulic system includes dual-circuit auxiliary lines with an electronic diverter valve, allowing operators to run a hydraulic thumb alongside other high-flow attachments like hydraulic breakers, compactors, and augers.

Can this excavator be legally towed on an equipment trailer?

Yes. With an operating weight between 8,889 and 10,161 lbs, the ET42 can be transported on a standard 14,000-lb GVWR equipment trailer behind a properly equipped 3/4-ton or 1-ton pickup truck (such as a Ford F-250/F-350).

Where can I inspect or demo the Wacker Neuson ET42 in Western Washington?

The ET42 is in stock and available for walkarounds and demonstrations at Leitz Farm Supply & Equipment Sales, located in Sequim, Washington, serving contractors and property owners across Clallam, Jefferson, Kitsap, and surrounding counties.
