All specifications on this page were taken directly from Spartan, the manufacturer. Figures from Spartan KGZ-XD specifications, checked November 2, 2026: Spartan KGZ-XD specifications.
Speed and fuel for long days
The KGZ-XD reaches 15 mph forward. Parker HTG transaxles with 16cc drive motors handle the drive. That's 2 mph more than the SRT-XD.
The tank holds 17 gallons. That's close to twice the 9.5 gallons on the SRT-XD. If you're mowing big ground all day, you'll stop for fuel less often.
One engine runs both decks. It's a 40 hp Vanguard EFI at 994 cc, with Oil Guard. So you're only choosing the deck.
It's a crew mower first. Think landscape crews, subdivisions, cemeteries and right-of-way work. On long, open runs, 15 mph gets you to the next pass sooner.
Reverse is 6 mph, 1 mph more than the SRT-XD.
Deck, tires and seat
The deck is reinforced 7-gauge steel, full-floating and 6 inches deep. You can get 61 or 72 inches. Overall, they measure 61.1 and 73.5 inches. Cutting height runs from 1.5 to 4.75 inches in 14 positions.
It rides on Michelin Tweel tires front and back. The fronts are 13x6.5-R6 and the rears are 24x14-R12. Spartan lists the weight at 1,310 lb.
How does it compare to the SRT-XD? Both offer 40 hp Vanguard power, 16cc Parker HTG transaxles and the same deck sizes. The KGZ-XD adds speed, fuel and Tweel tires. The SRT-XD adds Smart Ride suspension.
The 72-inch, at 73.5 inches wide, needs a wide gate and a wide trailer.
You'll sit in a custom blackout seat on adjustable TecsPak elastomer supports and a 360-degree floating platform. Browse our mowers on j5tractors.com, then call the store to talk about your crew's work.

Questions people ask
How fast does the Spartan KGZ-XD go?
The Spartan KGZ-XD reaches 15 mph forward and 6 mph in reverse. It drives through Parker HTG transaxles with 16cc drive motors. That's 2 mph more than the SRT-XD going forward, which adds up when you're crossing a big property.
How big is the fuel tank on the Spartan KGZ-XD?
The Spartan KGZ-XD carries a 17-gallon fuel tank. The SRT-XD and RT-HD carry 9.5 gallons. If your crew's mowing from morning to evening, a bigger tank means you won't stop as often to refuel.
What tires come on the Spartan KGZ-XD?
The Spartan KGZ-XD rolls on Michelin Tweel tires front and rear. The fronts are 13x6.5-R6 and the rears are 24x14-R12. It's the same tire setup on both the 61-inch and 72-inch decks, so you won't have to choose.
How much does a Spartan KGZ-XD mower cost?
We keep current pricing on our live inventory page at j5tractors.com, where our Conroe, Navasota, Normangee and Buna stores list the Spartan mowers they have.
