MODEL OutStander® SO37 Features & Benefits

LED Work Lights

  • LED work lights provide improved visibility in low light situations.

Rugged Construction

  • Robotically-welded steel construction for long-lasting durability
  • Centered-bearing design provides greater load-bearing capacity to handle the weight of operator, fuel and high-capacity collector with reserve strength for curb shocks and weight shifts
  • Tough-as-nails powder-coated finish is fusion-bonded for chip and rust resistance

Low Center of Gravity

  • Every Grasshopper mower is designed with a low center of gravity for optimal traction and stability. The centralized location of the engine, T-Drive™ pump and dual fuel tanks on Stand-On models lowers the overall center of gravity, and a total fuel capacity of 9.25 gal/35.0 L reduces the need for frequent refueling.

    Easily fit more units on trailers and maneuver through tighter spaces.

Warranty

  • 2-year unlimited hours; limited warranty covering parts and labor.
