2 Pack Hydraulic Filter Fits Spartan Replaces 450-0023-00

What It Is

This is a 2-pack of hydraulic oil filters designed for Spartan mowers, replacing OEM part number 450-0023-00. It filters contaminants from the hydraulic system fluid to protect pumps and motors in zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your Spartan mower model (e.g., RT, RZ, or Pro series) and year. This filter also fits some Gravely, Ariens, and Bob-Cat models that use the same OEM part. Measure the filter dimensions: typical thread size is 3/4-16 UNF, gasket ID about 2.5 inches. Cross-check your machine’s hydraulic filter part number against 450-0023-00. Aftermarket compatibility may vary—check for proper bypass valve specs (usually 15-18 psi) to avoid system damage.

Key Things to Know

• Quality: Aftermarket filters may have slightly lower micron ratings than OEM; verify if your system requires a specific efficiency (e.g., 10 micron).
• Installation: Easy—spin off old filter, lube gasket, hand-tighten 3/4 turn. No special tools needed.
• Gotcha: Use only with compatible hydraulic oil (typically 20W-50 or 15W-50); wrong oil can void warranty or cause pump cavitation.
• Gotcha: The 2-pack saves money, but if you only need one, check the price per filter vs. single units.

Should You Buy It

If you own a Spartan mower (or a compatible model) and need a cost-effective alternative to OEM filters, this 2-pack is a solid value at $17.99. It’s best for routine maintenance—just confirm your system’s pressure and oil specs first. Skip if your mower is still under warranty and requires OEM parts only.
