DESCRIPTION

Restore peak performance to your commercial zero-turn mower or upgrade your residential machine to commercial-grade reliability with Hydro-Gear Commercial Hydrostatic Transmissions the industry's most trusted and widely-used hydrostatic drive systems for professional lawn care equipment. Designed for commercial landscaping contractors, municipal maintenance crews, golf course operators, equipment repair professionals, and serious property owners who demand professional-grade performance, these genuine Hydro-Gear hydrostatic transmissions deliver smooth, precise control, exceptional durability, and the proven reliability that has made Hydro-Gear the OEM choice for virtually every major mower manufacturer worldwide.

This comprehensive offering includes three critical replacement options: the Hydro-Gear 3100 Series Right Side Transmission (Model ZL-GHEE-3B7B-2DLX, SKU 20107) and the matched pair of Hydro-Gear 2800 Series transmissions featuring both Right Side (Model ZK-GHEE-SB7B-2DLX, SKU 18094) and Left Side (Model ZK-KHEE-SB7C-3DLX, SKU 18093) configurations. Whether you're replacing a failed transmission on a single side or performing a complete dual-transmission rebuild on your zero-turn platform, these genuine Hydro-Gear units ensure exact OEM fit, function, and performance specifications.

Hydro-Gear's integrated hydrostatic transmission design combines the hydraulic pump, motor, and control valve into a single sealed unit, eliminating the complexity of separate hydraulic components while delivering infinite speed control, instant forward-reverse transitions, and the precise maneuverability that defines professional zero-turn mower performance. The closed-loop hydraulic system maintains consistent drive power whether you're navigating tight spaces around landscape features, powering up steep slopes, or maintaining straight tracking during high-speed transport across open areas.

Who This Is For: Essential for commercial lawn care companies maintaining zero-turn mower fleets, equipment repair shops servicing professional mowers, golf course and sports field maintenance departments, municipal parks and recreation crews, property management companies operating commercial equipment, serious residential users with commercial-grade zero-turns, and equipment refurbishment specialists rebuilding used commercial mowers for resale. These transmissions are critical components for maintaining the productivity and reliability that professional operations depend on daily.

Machine Compatibility: These Hydro-Gear transmissions are designed for commercial and residential zero-turn mowers equipped with engines in the 15-30 horsepower range. The 3100 series typically supports commercial zero-turn platforms with cutting decks from 48-60 inches, while the 2800 series is commonly found on both commercial and heavy-duty residential zero-turn mowers with 42-54 inch decks. Compatibility depends on exact model specifications verify your equipment's transmission model number before ordering to ensure proper fit.

Installation & Configuration: The right-side and left-side designations refer to the transmission position when seated in the operator position facing forward. Zero-turn mowers require matched left and right transmissions for proper operation the control linkages, mounting orientations, and internal valve configurations differ between sides. When replacing a single failed transmission, you must match the exact side and model. When rebuilding both sides, consider replacing both transmissions simultaneously to ensure matched wear characteristics and consistent performance.

Unique Benefits: Genuine Hydro-Gear transmissions represent original equipment quality the same units installed by mower manufacturers during initial production. Unlike aftermarket alternatives that may use inferior materials or compromised engineering, genuine Hydro-Gear units deliver the precise control response, durability, and service life that professional operators demand. The sealed design protects internal components from contamination, while the integrated cooling system maintains optimal operating temperatures during extended commercial use. Hydro-Gear's legendary reputation is built on millions of transmissions delivering decades of reliable service in the harshest commercial environments from scorching desert landscapes to humid southern climates to dusty agricultural properties. When your livelihood depends on equipment uptime and your reputation rides on consistent cut quality, genuine Hydro-Gear transmissions are not an expense they're an investment in productivity, reliability, and professional results.
