Honda 663020 Pros and Cons

Here are some potential pros and cons of the Honda 663020 walk-behind tractor:


  • Powerful and efficient 524cc 4-stroke OHV engine provides ample power for various tasks
  • The hydrostatic transmission provides smooth and comfortable operation
  • Zero-turn radius capability and maneuverability for tight spaces
  • Hydraulic lift allows using optional attachments like mid-mount and rear-mount mowers
  • A low center of gravity enhances stability for mowing hills and inclines
  • Foot-controlled differential lock for enhanced traction in slippery conditions
  • Large rear tire size (23×10.5-12) provides good floatation
  • Durable construction and reputation for a long lifespan of Honda engines


  • Higher upfront cost compared to other walk-behind tractor options
  • Requires more maintenance than basic walk-behind mowers
  • Heavier and less maneuverable than self-propelled push mowers
  • The learning curve to master the zero-turn steering
  • Optional mid- and rear-mount attachments increase the cost

  • Fuel efficiency is not as high as gas push mowers for small lawns

Overall, the Honda 663020 provides heavy-duty performance for commercial and estate-sized lawns, but the upfront investment, learning curve, and fuel costs may not make sense for smaller residential properties.
