Sports Attack Throwing Wheel – Hack Attack Baseball

The Hack Attack Baseball pitching machine uses a unique three-wheel throwing design, with each 14-inch concave wheel driven by its own variable-speed motor. This replacement is the same solid (non-air-filled) concave throwing wheel used on the original machine. The high tensile, heat-treated alloy, weather-resistant aluminum casting that Sports Attack describes is the throwing head that protects the throwing mechanism, not the wheel itself.

Because the Hack Attack grips the ball in three locations rather than two, wear on both the wheel surface and the baseball itself is reduced compared to two-wheel machines. Sports Attack states it has never had to replace a throwing wheel due to wear, weather exposure, or heat-related melting (a manufacturer statement, not a warranty term).

Each wheel plays a direct role in the machine's pitch versatility: adjusting the relative speed of the three wheels lets the Hack Attack throw fastballs, curveballs, sliders, split fingers, sinkers, and more, all without tilting the throwing head. A properly matched replacement wheel is essential for maintaining accurate speed range (35 to 100+ MPH) and consistent pitch behavior across all these pitch types.

This wheel is intended for use only with regulation leather baseballs, dimpled or polyurethane practice balls, whiffle balls, and foam balls; synthetic leather balls should be avoided since they wear quickly and can leave residue buildup on the wheel surface, affecting long-term performance.

As a service part, this throwing wheel is designed to be replaced in the field using only a few common tools, with no need for local technician assistance. Sports Attack's warranty covers wear components, including throwing wheels, controllers, and motors, for two (2) years for residential and institutional buyers or one (1) year for commercial use from the date of original purchase; normal wear and tear is not covered. The wheel is also available bundled as a full set of three for complete wheel replacement.

Why are Sports Attack throwing wheels considered higher quality than competitors' wheels?

They're made from carefully tested components in a solid design with no air pressure concerns, and the manufacturer states it has never replaced a wheel due to wear, weather, or melting.

How difficult is it to replace a throwing wheel on the Hack Attack?

Component parts are designed for easy field replacement without needing local technician assistance; only a few common tools are required, and a parts list is available in the machine's manual.

What types of balls should be used with the throwing wheels to avoid damage?

Use regulation leather baseballs, dimpled or polyurethane practice balls, whiffle balls, or foam balls; avoid synthetic leather balls, as they wear quickly and can leave residue buildup on the wheels.
