Deep Walled, Fabricated Steel Deck
- Deep walls offer the best parameters for maintaining the requisite air stream for collection.
- Stylish, bubble top deck pans work well for mulching, but don't afford clearance for good air/clipping flow above the blade tip, where 99% of all cutting is done, and thus the most critical.
- Service features include single point timing belt adjustment, grab bars to facilitate manipulation, and garden hose attachments for easier cleanout.
- True floating attachment and tool free deck removal.
Stainless Steel Deck Pan Option
- Stainless steel offers offers greater corrosion, impact, and abrasion resistance than mild steel. It looks nice and it can last much longer.
Synchronized Blades, Overlapping (80 mm overlap) Blades
- Synchronized, overlapping blades is the only way to go when cut and collection performance is key.
- Great first pass results, even in wet or overgrown grass. Above standard overlap increases collection performance and dramatically reduces rooster-tailing in extreme conditions.
- Kevlar reinforced (the same stuff from which bullet proof vests are made from) timing belts for superior life.
- Steel timing pulleys for maximum service life and minimal maintenance.
Enclosed Clipping Tunnel with Patented CleanSweep
- Fully enclosed tunnel maintains greater airflow for better cut and collection performance. The CleanSweep system ensures complete removal of any clippings that may remain in the tunnel after dumping.
30-130 mm Deck Lift Range
- Large range of motion affords the best opportunity to suite mowing or leaf collecting conditions.
EZ Adjust Blade Boss
- Outstanding durability and ease of blade attachment & positioning (90° blade relation).
Austempered Steel Blades
- Ultra tough, laser cut blades provide well above average service life. Available in standard or aggressive high lift versions.

600 litre collector with PowerLift - (over 98% Usable volume)
- Fingertip control of a massive collector. Bigger volume provides the best productivity, self-contained, maintenance free collector lift eliminates the strain.
- The collector can be packed full - the huge volume can be used completely. Some competitive machines claim larger volumes than can actually be practically achieved before the machine starts to plug.
Wisconsin's patented Full Bag Sensor offers the best protection against plugging
- Patented technology is the most accurate, most reliable system available. Our system precisely monitors air flow and can be used to automatically stop the blades when the collector is about 80% full to give reserve capacity for finishing cuts before dumping.
Precision Machined Steel Spindle Housings and Oversized Blade Shafts for Greater Durability
- The housing that holds the blade shafts take a lot of abuse. Commonly used cast aluminum and cast iron are brittle and cannot offer nearly the same level of durability or impact resistance as Wisconsin's exclusive steel housings.
- Large blades offer greater strength and impact resistance.
Steel Collector Netting
- Fabric netting is a cost effective solution, but steel offers the superior service life and durability; it's just about impervious to tearing, and is more resistant grass "juices" that are the end of most fabrics.
Large diameter adjustable casters
- Four solid, height adjustable casters provide improved anti-scalping performance.
Built for Thousands of Hours of Trouble Free Operation
Extremely Strong Front Axle and Axle Attachment
- The front axle is subject to a lot of stress and strain. The front axle and attachment of the W-3600 is designed and built to deal with this. The axle body is fabricated from heavy gauge steel, jack shafts and housings are extremely strong, and the whole assembly is embedded solidly into the chassis by oversized frame members.
Welded Steel Chassis
- Welded steel profile is durable and stiff, and does not suffer annoying flex in uneven terrain. Provides the weight necessary for good plowing and heavy attachment performance.

Premium Corrosion Resistance
- Grass juices, fertilizers, water, and salt are present in practically all mowing and maintenance environments. The W-3600 features premium treatments and components to keep corrosion at bay:
- Baked Enamel: powder paint offers excellent chip resistance.
- Acrylic Coated ABS: impervious to sun fade and increased scratch resistance.
- Zinc Chromate Conversion: long life protection for unpainted parts
Steel Fender
- Durable and more readily repaired than ABS.
Steel Hydraulic Oil Tanks
- Better hydraulic oil cooling for demanding applications.
Automotive Style Relay Electronics
- No printed circuit boards. Mechanical relays are easy to find as spare parts and can be serviced, unlike printed boards.
Fabricated Steel Wheels
- Ultra tough double hull wheels that can take punishment without bending
Jack of All Trades
Wisconsin Front Hitch and Hydro Power Pack Ready
- The optional front hitch allows use of active or passive implements such as blowers, sweepers, and blades. The optional power pack is an easy to install source of hi volume hydraulic power for use with front hitch mount or hydraulic tow behind implements (utilizes full engine power) that is controlled through the pto switch
Premium Drive
All Hydraulic Drive System: Premier axial piston pump and wheel motors feature greater efficiency (fuel savings) and among the best in terms of reliability.
Silky Smooth Power Steering: Optimized power steering provides just the right mix of ease, feedback, and motion for a great, fatigue-free feeling of precision. Powerful hydraulics ensure this is maintained even under heavy loads, for example, when using the optional front mount snow blower.
Step Through Chassis: Easier to get into and out of the operator's station. Gives the operator room to be more comfortable.
Arm Rest and Tool-Free Adjustable High-Back Seat: Full support seat offers increased comfort for big jobs
Grab Bars - Hood and Fender: Aid entry into operators station and provide a convenient place to grab on to when moving the machine, for example, in a cramped garage or trailer. Fender bars offer room in which extra fuel and toolboxes can be strapped.
Halogen Headlights: Extra bright halogen headlights offer greater visibility - for both work and safety - in low light conditions.
High Travel Speed: Faster drive means less wasted time travelling to-from dump site and between job sites
Service Friendly
Deluxe Hour Meter & Tachometer: Helps to monitor service intervals
Accessible Service Points: Routine service points are clearly exposed and easy to access. Filters and belts are readily accessed.
One Piece Flip Forward Hood: Removing the entire hood assembly takes less than 10 seconds for complete and unobstructed access to engine bay.
Hydraulic Drive: A single belt powers the pump in the advanced drive system. No clutches or linkages to adjust or fail.
