Spartan Mowers revealed new models and product upgrades on Sept. 9 during its National Dealer Meeting in Jacksonville, Fla. Additions to the lineup include the redesigned Shield, Shield-HD, and Defender, along with the RZ-XD and RZ-XD Blackout.

Entry-level options of the Shield and Shield-HD are available in 42- or 54-in. decks with a

Kawasaki 23 HP engine. Both models feature Hydro-Gear transmissions, 20-in. Carlisle Turf Armor rear tires, a five-in. cut height, and a top speed of seven MPH.

The Defender is an all-new model with folding ROPS, full-beam LED light kit, 22-in. Carlisle

Turf Armor rear tires, a premium seat, and a top speed of eight MPH. Deck sizes include 48-, 54-, or 60-in. along with Kawasaki engines of either 23 or 24 HP.

 The brand-new RZ-XD is a step up from the best-selling RZ-HD with a Kawasaki FX730 23.5 HP engine, 24-in. Reaper tires on the rear, and a suspension seat. The RZ-XD Blackout rounds out the series with a Kawasaki FX801 25.5 HP engine, 24-in. radial comfort tires, premium suspension seat, and a custom blackout design.

Upgrades across the lineup include a common frame between RZ, RT, SRT, and KGZ mowers. In addition to enabling all mowers in these series to have a hitch, a common frame allows for easier maintenance with newly designed bolt-on components that simplify serviceability and eliminate the need for a full-frame replacement.

Electrical upgrades were designed to enhance both functionality and ease of use. A new hour meter provides engine hour tracking that only records time when the engine is running. Additionally, the hour meter features a tachometer that provides real-time engine RPM information on the display. Other improvements include a sealed fuse box and optimized wire lengths to reduce clutter and simplify the electrical system. Last—but not least—model year 2025 decks have been modified to improve cut discharge and enhance the processing of grass clippings by adjusting the spindle location and baffle positioning. Deck durability will also be boosted with thicker baffles of seven-gauge steel.

The complete 2025 lineup includes the Shield, Shield-HD, Defender, RZ-HD, RZ-XD, RZ-XD

Blackout, RT-Pro, RT-HD, SRT-XDe, SRT-XD, and the KGZ-XD. Spartan Mowers are only sold through authorized independent dealers.
