Cast-Iron Blade Spindles

Cutter-blade drive spindles are a crucial component to mower performance. The average blade spindle rotates over 1.8 MILLION times in eight hours of cutting. That’s 9 million times per week! Can you afford to have anything but the BEST blade drive spindles turning your cutter blades? Absolutely not!

Scag^® cast-iron spindle housings* are cast in Wisconsin and precision-machined at Scag with state-of-the-art machining centers to ensure a perfect fit for the tapered roller bearings. Every Scag cast-iron spindle is assembled by a high-precision, robotic assembly cell.

This is the best-performing, most reliable spindle in the commercial industry…hands down. We have been using this same rock-solid design for many years and proudly stand behind them with a 3-year limited warranty.

*Liberty^® Z, Freedom Z^®, Patriot™ and SWZT feature sealed-aluminum spindle.

Tapered Roller Bearings

Scag spindles utilize a matched set of tapered roller bearings. Tapered roller bearings have 50% more load capacity than ball bearings. The taper angles allow the bearing to handle a combination of radial and thrust loads, unlike a ball bearing.

Cast-Iron Housing

Cast-iron spindle housing provides increased shock-load strength over aluminum housings, making them super-strong to take the everyday abuses of mowing. In 2004, Scag spindle housings were upgraded to an even thicker mounting flange, increasing strength by 163%!

Hardened Spindle Shaft

1 1/8" diameter. Extra-large diameter, hardened spindle shaft provides superior strength. Key groove is cut into shaft for solid pulley mounting.

Easy Servicing

Top-mounted grease fitting for quick and easy access. No need to crawl under the cutter deck.

Grease-Relief Valve

Special relief poppet valve ensures that "over-greasing" and damaging a seal is impossible, even with powered grease guns. The valve is spring-loaded to prevent debris from entering the housing, unlike "weep holes."

Blade Bolt Mounting

Cutter-blade retaining bolt travels through the center of the shaft. Under extreme impact, only the bolt may need to be replaced, not the entire spindle assembly. The thru-bolt design also allows you to change blades without altering the proper preload (150 ft lb) on the tapered roller bearings.
