Troy-bilt 787-02002B-0638 21 in 3-in-1 Mower Deck

Product Description

The TROY-BILT 787-02002B-0638 is a 21-inch 3-in-1 replacement mower deck designed for walk-behind rotary lawn mowers. This deck assembly supports three cutting discharge modes: rear bag, side discharge, and mulch, making it a versatile service replacement for worn or damaged deck housings. Licensed technicians and experienced service professionals handle deck swaps as part of routine mower refurbishment, restoring full cutting function without replacing the entire unit.

This deck is suited for residential walk-behind mower applications where the original deck has suffered structural damage, corrosion, or wear beyond practical repair. The 3-in-1 configuration is common in TROY-BILT consumer and prosumer walk-behind mower platforms. Installation is typical for outdoor power equipment service, requiring standard hand tools and basic small-engine mechanical knowledge.

• 3-in-1 discharge compatibility: rear bag, side discharge, and mulching
