Spartan RZ-HD 54" 23HP Kawasaki

Three deck sizes (48", 54" and 61") and three engine options, the RZ-HD is an excellent choice for large or small yards. The RZ-HD is patterned after the big guys with 5” deep 7 gauge XTF decks, ROPS, 22” rear radials, Parker hydraulic transmissions, and the Spartan signature styling. Everyone loves the looks and can't deny the performance.

Attachments & Accessories


  • All Spartan Mowers have a deck fabricated from 7 gauge steel, not just the top end models. Check out the competition and see the difference for yourself. No light duty decks here!

  • All models from RZ-HD and up have Parker Hydraulic drives (no gear reduction) for smoother, trouble-free operation. That’s up to 25% more efficient than gear reduction hydros.

  • Precharge pumps on every model RZ and up makes every hydrostatic drive smoother for precision control by eliminating pump cavitation.

  • It all starts with traction. Exclusive Radial Tires for better traction and softer ride are on all RZ-HD models and up.

  • Spartan Mowers are manufactured in the USA. Made with American steel, engines, hydro drives, custom seats, control panel, idler, pullies... the list goes on.

  • Xtreme Turf Flow (XTF) decks have been redesigned and enhanced to meet the spring, summer, and fall mowing conditions everywhere. This enhanced deck system comes standard on ALL models 42"-72".

  • Vibration controlled deck system with a one-piece idler pulley and shock absorber takes away belt whip and reduces vibration. The 'soft start electronic control' pulses electricity to the electric clutch at engagement to increase your clutch and belt life.

  • Foot controlled on and off parking brake so both hands can be on control sticks. Another great feature that helps keep you in control.

  • ROPS (Roll Over Protection) standard on all RZ-HD, RT and SRT models for operator protection. Fold down to clear enclosed trailers.

  • Our key pad allows you to personalize your code to start the mower. It also has a push button switch for accessories like lights, electric chute, etc. The screen shows engine hours, PTO clutch hours, when to change your oil and light indicators for diagnostics. It’s your mower’s personal assistant!

  • Spartan Mowers has engineered superior technology that combines perfect balance with superb incline control for a smoother, safer ride. Take it on an incline and feel the difference. *Industry standard does not recommend mowing on inclines over 15 degrees
