The SA 424 is made for tougher terrain.  The ground clearance is a little taller than the SA 324.  It still has the great operator platform, easy to use instruments and controls, comfortable seat, and a 3 cylinder liquid cooled diesel engine.  This tractor has a variety of attachments that can be used.   Yanmar stands behind their tractors with a 5 year warranty.  Starting at $14,840 tractor only. The SA424 also comes with a 4 post canopy option. That option starts at $16,463
