What Smart Ride means
Smart Ride is Spartan's name for the suspension. The rear section of the frame is independent, and it sits on Winamac coil springs. On top of that, you've got a full-suspension seat.
That seat rests on adjustable TecsPak elastomer supports and a 360-degree floating platform. On a long day across ruts and stumps, it's the ride you'll feel most.
Why does it matter? Without suspension, every bump runs through the frame and into your back. With the rear frame on springs, the ride's softer across ruts and pasture.
The numbers on the SRT-XDe
Both decks run Kawasaki's FX801V, rated 25.5 hp, with a 9.5-gallon tank. Parker HTJ transaxles with 12cc drive motors give you 11 mph forward and 5 mph in reverse.
The deck is reinforced 7-gauge steel, full-floating and 6 inches deep. Cutting height runs from 1.5 to 4.75 inches in 14 positions. The 54-inch measures 55.5 inches wide.
Tires differ by deck. You'll find 13x6.5-R6 radials up front on both. Rears are 20x10.5-R12 radials on the 54 and 24x14-R12 radials on the 61. Spartan lists the weight at 1,192 lb.
If you need a 54-inch deck with Smart Ride, the SRT-XDe is the one to look at. It fits a crew cutting subdivisions and church lots, or an owner with big ground mowed weekly.
Smart Ride and the seat are the same on both deck sizes, so you're choosing width, not comfort.
