V-400 Series
The Viper V-400 Series may be our smallest mower, but it’s built with the same DNA as the rest of the lineup. Compact in size but big on performance, the V-400 delivers a smooth, responsive drive and features a robust, welded frame designed for long-term durability. Its smaller footprint makes it ideal for navigating tight spaces, while still offering the comfort, strength, and reliability Viper is known for. Perfect for owners who want commercial-grade feel and performance without the bulk, the V-400 Series proves that serious mowing power can come in a smaller package.

Adjustable Baffling
Adjustable inner baffle allows you to customize the baffling height for different types of grasses and conditions, from thin or weedy areas to thick, heavy grass, as well as for mulching and bagging. XP only.
E-Coat & Powder Coat
Commercial multi-stage finishing process. Electro-coating base with thick, durable powder coat gives maximum corrosion resistance.
Deck Height Pin
Dual Fuel Tanks
Automotive-Style Wiring
With fully sealed Deutsch connectors and a weatherproof fuse and relay box, no one does it better.
Adjustable Handles
Ergonomic, dampened drive control handles adjust forward and back, as well as up and down, providing a comfortable, custom fit for virtually any operator.
Roll over protection
With over 900 lbs. of weight and muscle, the 452 and 460 are built like much larger commercial machines. That’s why a ROPS (Roll-Over Protective Structure) comes standard.
