About this item

• 【PERFECT FIT OEM REPLACEMENT BELT】603907 Pump Drive Belt with Exact 1/2” x 50.75″ dimensions. Direct replacement for Hustler OEM 603907 and 607400; compatible with Stens 265-699; Rotary 14939; A&I A-603907. Fits Hustler Raptor Series including Raptor SD, Raptor SDX, Raptor Limited, and Raptor Flip-Up zero-turn riding mowers (2013–2020 models).
• 【UPGRADE DUAL KEVLAR REINFORCEMENT】Built with a Kevlar-tensile cord for strong, stable tension under heavy loads, plus short Kevlar fibers blended into the rubber base to resist cracks and heat. This double-layer upgrade keeps the belt running — even as outer wraps wear down.
• 【BUILT TO LAST THROUGH SUN, HEAT & SEASONS】Crafted with weather-tough Neoprene that stands strong against UV rays and repeated outdoor use. Keeps its shape and power when standard rubber gives out — no need for springtime replacements.
• 【PRECISION FIT & CUSTOMER CARE】Most belt issues come from wrong sizing — that’s why we match to verified OEM specs. Just check the fitment info listed on this page to find your match. Need help? Our team is ready to assist with prompt, accurate answers.
• 【BUILT FOR EXTREME MOWING CONDITIONS】ROTIX Mower Belts aren’t made for casual use — they’re purpose-built for real mowing stress: high heat, sudden shock, dust, debris, and constant starts and stops. With a Kevlar tensile core for strength, fiber-reinforced rubber for crack resistance, and a dry-wrap outer layer for stable grip, this multi-layered build delivers lasting performance where standard belts wear out fast.
