2020 Grasshopper 623T Front Mount Zero Turn


An ideal FrontMount(tm) solution for home or business use, the Grasshopper Model 623T riding lawn mower with zero-turn maneuverability offers the power, reliability and economical performance that homeowners and lawn care professionals need to get the job done. Make quick work of cleaning the underside of the cutting deck with the exclusive PowerFold(r) deck lift/electric height adjustment feature. The front-mounted deck removes and can be replaced with turf renovation and snow removal implements for year-round productivity.

Reach under shrubs, fences and low-hanging branches to reduce trimming and deliver a perfect cut wherever you mow. It's easy with a Grasshopper low-profile, out-front mowing deck. Designed for maximum productivity and easy serviceability, these extra-deep decks are designed for superior airflow, so you'll get beautiful results in both cool and warm season grasses, including Bahia.

Grasshopper's line of out-front mowing decks let you handle clippings any way you like, with choices designed for maximum flexibility and outstanding performance. Best of all, the standard PowerFold(r) feature found on all out-front mowing decks creates space-saving portability and provides for simplified blade sharpening and underside deck cleaning.

-Kohler Command Pro Engine

694 cc, 2-cylinder, air-cooled Kohler Command V-Twin engine

-PowerFold(r) Electric Deck Lift

Standard on all FrontMount(tm) DuraMax(r) decks, PowerFold(r) is the zero-turn mower industry's first electric deck lift (introduced in 2004).

PowerFold(r) rotates the deck nearly 90 degrees to provide easy access to the underside of the deck for simplified maintenance and mulching package installation, plus space-saving portability and storage.

The feature also adjusts cutting height between 1.25 and 5.0 inches and controls deck lift functions using a single switch.

-Heavy-duty Deck

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(tm) mulching or PowerVac(tm) collection
Sentry(tm) 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(tm) spindle guards shield spindle housing and seal lower bearings from fiber wrap and dirt ingestion

-Vigilant Operator Presence System(tm)

Standard, low profile operator protection structure (OPS) 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

Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

-Ultimate Operator Station(r)

Operational controls including throttle, choke and angled View-Eze(tm) console and adjustable cup holder are well positioned for visibility and ease of reach
One- or two-handed operation with ComfortReach(tm) adjustable Hydra-Smooth(tm) dual levers that automatically return to neutral from either forward or reverse position.
