Engines by deck size
The 48-inch RZ-HD comes with the 24 hp Kawasaki FR730V. On the 54 and 60, you can pick that Kawasaki or the Briggs CXI, rated 27 hp. All of them carry a 9.5-gallon tank.
The deck is reinforced 7-gauge steel, 5 inches deep, and it floats. Cutting height runs from 1.5 to 4.75 inches in 14 positions. The 60-inch with the Kawasaki is the exception: it goes from 1 to 5 inches in 15.
Parker HTE transaxles with 10cc drive motors run it up to 9 mph forward. Reverse tops out at 5 mph.
A floating deck rides with the ground instead of with the frame. It follows dips and humps a little better, so you're less likely to scalp a high spot.
A step up for acreage
If you're mowing a couple of acres on up every week, this is where the bigger tank and floating deck start to matter. A 9.5-gallon tank means fewer trips to the gas can.
Tires change with the engine. The Kawasaki models run 23x11-12 Reapers in back. The Briggs models step up to 24x12-12 Reapers. Fronts are 13x6.5-R6 smooth tread, and the 54 and the Briggs 60 offer a radial upgrade.
Want more engine? The Briggs CXI gives you 27 hp, which is 3 hp more than the Kawasaki. The 48-inch is Kawasaki only, so if you'd like the Briggs, start at 54.
Spartan lists the weight at 907 to 1,095 lb. You'll sit in Spartan's deluxe seat. Want a floating seat platform instead? Look at the RZ-XD. Browse our zero-turn mowers on j5tractors.com to see the RZ line.

How fast does the Spartan RZ-HD go?

Most Spartan RZ-HD models cut from 1.5 to 4.75 inches in 14 positions. The 60-inch deck with the Kawasaki engine goes from 1 to 5 inches in 15 positions. If you like a lower or taller cut, that's the one to ask about.
