Kohler ZT740-3013 25.0HP 747cc V-Twin Engine – 1-1/8in Shaft, Electric Start

Description

Delivering 25.0 rated horsepower, the Kohler ZT740-3013 vertical shaft engine powers commercial zero-turn mowers through dense turf without bogging down. Landscape maintenance contractors face costly downtime when underpowered vertical engines overheat in high summer temperatures and burn valve seats. This 747cc commercial Confidant Series engine incorporates an oversized 1-1/8-inch vertical crankshaft, heavy-duty cooling fins, and cast-iron cylinder sleeves that maintain bore roundness under continuous cutting shifts.

An onboard 12V electric starter motor turns the flywheel ring gear with key-switch operation, bypassing operator recoil fatigue during long routes. The oversized 1-1/8-inch output shaft handles heavy commercial electric blade clutches and dual hydrostatic transmission pulleys without lateral deflection. Full-pressure lubrication circulates filtered motor oil through an automotive spin-on canister, protecting journal surfaces against premature friction wear during steep hill mowing.

Key Engineering Features of Kohler ZT740-3013

• 747cc 25.0HP Confidant Commercial V-Twin: Produces 25.0 rated horsepower to sustain high blade tip speed in thick, overgrown grass.
• 1-1/8-Inch Heavy-Duty Vertical Shaft: Oversized commercial diameter matches heavy electric blade clutches and transmission drive pulleys.
• Full-Pressure Lubrication with Spin-On Filter: Pumps clean oil continuously to crankshaft journal inserts and rod bearings.
• Cast-Iron Cylinder Bore Liners: Maintains cylinder roundness and ring seal when cutting in abrasive sandy soil conditions.
• Heavy-Duty Commercial Canister Air Cleaner: Traps fine dust particles across two media layers to preserve cylinder wall compression.
• 12-Volt Solenoid Shift Electric Starter: Provides fast key-turn starts that eliminate operator pull-cord fatigue.

Field Durability & Operational Economy

Built for professional turf contractors who track fleet operating expenses, this vertical-shaft engine eliminates repetitive maintenance interruptions.

• A cast-iron cylinder sleeve and precision-machined shaft journals resist side-load belt stress under high cutting tension.
• High combustion efficiency lowers fuel burn per mowing shift, cutting daily operating expenses across commercial fleets.
• Landscape maintenance contractors and estate groundskeepers gain dependable power for high-hour zero-turn mowers.

Equipment Fitment & Repower Applications

Weighing 89 pounds dry with a standard commercial vertical mounting pattern and 1-1/8-inch shaft, this engine mounts directly onto 60-inch and 72-inch commercial zero-turn mowers, stand-on turf units, and wide-area lawn tractors without deck alterations.

Warranty Coverage & Field Maintenance

• Commercial fleet operators receive 3-Year limited factory warranty coverage against component defects.
• Residential and estate owners receive 3-Year complete consumer warranty protection.

Change engine oil and filter after the initial 20 operating hours, then service every 100 hours with SAE 30 or 10W-30 motor oil. Inspect the air filter weekly on dry cutting routes, and maintain spark plug gaps at 0.030 inches.
