Vehicle Summary

Vehicle Detail

We put new hydrostatic power into the National 8400 which makes it even better on slopes. The 8400 also makes tough mowing jobs easier by adding power steering and a more comfortable ride. We also designed it to give you a better cut. Independent Reel and Ground Speeds.

Hydrostatic drive provides independent reel and ground speeds for the finest reel cut of any mower in the industry. You get the same perfect cut at any speed, whether you slow down to trim or speed up for the more open areas.
