Features

Features

  • REAR RADIAL TIRES: It all starts with traction. Exclusive Radial Tires for better traction and softer ride are on all RZ-HD models and up. Challenge our ride against others out there and you’ll feel it for yourself. *RZ-C, RZ, and RZ-Pro not included. RT-HD and above come standard with front radials.
  • HD FUSION WELDED FRAMES: Our frames on all RT and SRT models are constructed from the same tubing as our frames on our 65 MPH Intimidator UTVs. Spartan Mowers are built tough, there’s no doubt about it!
  • 7 GAUGE STEEL DECKS: 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!
  • RECEIVER HITCH: All RT and SRT models come equipped with a built-in 2” receiver hitch. Just think about all the possibilites.
  • KEY PAD: 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!
  • HYDRAULIC DRIVE: 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. Who doesn’t love being more efficient?
  • FOLDING ROPS (ROLL OVER PROTECTION SYSTEM): ROPS (Roll Over Protection) standard on all RZ-HD, RT and SRT models for operator protection. Fold down to clear enclosed trailers.
  • PARKING BRAKE PEDALS: Foot controlled on and off parking brake so both hands can be on control sticks. Another great feature that helps keep you in control. Test drive and see what you think for yourself.
  • ADJUSTABLE SEAT: Exclusive Spartan Mower seats offer supreme comfort for an ‘all day ride.’ A 3” adjustable seat made with Dymetrol® material, coupled with adjustable TecsPaks® elastomers under the seat platform offers a ride that’s above industry standard. We don’t compromise on comfort. (RT-HD and SRT Models)
  • MAUFACTURED IN USA: Did you know that we are manufactured in the USA? Made with American steel, engines, hydro drives, custom seats, control panel, idler, pullies... the list goes on.
  • 12V OUTLET: Not only a place for your phone, but a way to charge it or to power other 12V items. *RZ models - storage pocket not included
  • ANTI-SLIP MAT: All models are equipped with a rubber anti-slip foot mat. These mats help reduce vibration from the transmission to the operator’s foot.
  • RESILIENT BUSHINGS: Special resiliant bushings on the mower stabilizing arms reduce the shock and damage to the mower if it hits curbs, stumps, or other debris.
  • VANGUARD QUIET RIDE EXHAUST: RT-HD, SRT-HD, and SRT-XD have a Quiet Ride high-end insulated exhaust system. Check these out on all Big Block Vanguard® models.
  • VIBRATION CONTROLLED DECK: 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.
  • CHARGE PUMPS: Precharge pumps on every model RZ and up makes every hydrostatic drive smoother for precision control by eliminating pump cavitation.
  • HILLSIDE / TRACTION: 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
