Offering intense mowing power in a surprisingly compact design, the Model 329B is made to run with the big boys, offering powerful, efficient and economical performance.
Features & Benefits
Extra-deep, 5.5-inch deck is fabricated from heavy-gauge formed steel with a reinforced anvil edge. Specially designed cutting chambers enhance airflow for better cut quality. Deck easily converts from side discharge to optional Down Discharge™ mulching or PowerVac™ collection. Sentry™ spindles with massive, 8-inch flanges anchored in a 6-bolt pattern, spread the force of impact for greater strength. Spindle planes are fabricated from double-layered formed steel laminate and combine with the spindles to form a triple-strength deck to keep blades level and deliver a high-quality cut. Sentry™ spindle guards shield spindle housing and seal lower bearings from fiber wrap and dirt ingestion.
Raise and lower the deck easily with foot pedal and drop pin for precision cutting heights between 1.0 and 5.0 inches.
896 cc, air-cooled OHV Vanguard Big Block V-twin engine with horizontal crankshaft for longer life.
Commercial Use: 3-year unlimited hours; limited warranty covering parts and labor. Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.
Robotically-welded steel construction for long-lasting durability. Centered-bearing design provides greater load-bearing capacity to handle the weight of operator, fuel and high-capacity collector with reserve strength for curb shocks and weight shifts. Tough-as-nails powder-coated finish is fusion-bonded for chip and rust resistance.
Only two Access-Eze™ lubrication points cut maintenance time up to 95%. Self-tensioning belts minimize cost and labor on routine maintenance.
ComfortZone™ seat eliminates jostles and jolts with coil-spring suspension and a fully padded, high-back seat, padded armrests and variable density foam cushion. Iso-mounting smooths the ride, erases fatigue and keeps the operator comfortably in control at faster mowing speeds. Operational controls including throttle, choke and angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach. One- or two-handed operation with ComfortReach™ adjustable Hydra-Smooth™ dual levers that automatically return to neutral from either forward or reverse position.
Deep-cushioned, high-back, foam-padded, scuff-resistant Cordura®-covered seat with padded lumbar support and armrests. Roomy, iso-mounted, shock-absorbing footrest.
Standard, low profile Roll-over Protection System (ROPS) structure with an adjustable seatbelt. Dampened steering levers that return to neutral from forward and reverse. Interlock switches that shut down the engine when the operator leaves the seat while PTO is engaged or levers are in drive position.
Robust G2 transmission features 7-micron absolute filter and CoolFan™ hydro cooling system. HydroGear variable displacement 16 cc piston-pumps and high-torque Parker wheel motors. Provides 1,000-hour transmission fluid change interval.

The optional Down Discharge™ mulching package with GrassMax™ medium-lift blades cuts and recuts clippings and directs them deep into the grass bed, enriching turf and producing a beautifully manicured cut.
PowerVac™ Collection Systems deliver a clean sweep on every pass. Simply adjust your mowing speed to your conditions. Quik-D-Tatch® Vac drive can be removed in seconds without tools.
Available for all MidMount models, optional QuikAjust Tilt™ steering levers (except 124V-41) with "no tools" adjustment provide a 9-inch range for maximum comfort and fit while maintaining natural arm and wrist positions.
Lightweight, water repellent, UV-resistant vinyl canopy mounts easily to OPS or ROPS to limit exposure to direct sunlight, reducing eye strain and increasing operator comfort.
Yellow beacon attaches to OPS or ROPS to provide greater visibility in high-traffic areas.
Weather-resistant, black Cordura fabric cover with embroidered Grasshopper logo keeps seat and engine area protected during storage or between mowings. Slips over ROPS, with Velcro closure to secure the opening.
Dedicated 48-, 52- or 61-, or 72-inch rear discharge decks throw clippings out back for a smooth cut and no windrowing.
The Electric Height Adjustment kit offers 1- to 5-inch height adjustment control from the operator's seat with the flip of a switch. This dealer-installed option is available for all 200 and 300 Series MidMount™ models.
LED work lights provide improved visibility in low light situations.
Provides an additional two inches of leg clearance.
Provides additional seating room for larger operators or to accommodate cell phones or pagers. Requires seat belt extension.
The Foldable ROPS allows the two-post ROPS to be lowered for mowing under low-hanging trees and other overhead obstacles, or for storing and transporting in enclosed trailers with low door clearance. CAUTION: Avoid drop-offs, embankments and steep slopes. Do not allow ROPS to provide a false pretense of security in hazardous areas and avoid questionable conditions. Always wear seatbelt when Foldable ROPS is in up-right position. When Foldable ROPS is down, DO NOT use seat belt, and drive with extra caution.
Optional low-pressure, high-flotation bar-tread tires are available for 61- and 72-inch models that flex with the terrain for maximum traction and minimize scuffing caused by wheel spin-out.
