Pro Parts Place PPP 3-Pack 18" XHT HD MARBAIN Lift Mower Blades — 5/8" Center Hole, USA-Made

Built in the USA and marketed as a direct, high-performance replacement for OEM part GRAVELY 03253800, this three-pack of 18" x 2-1/2" x 5/8" center-hole blades delivers increased hardness, improved wear resistance, and reduced weight compared with many imported alternatives. The blades are made from PPP's patented MARBAIN material, offering a balance of strength, toughness, and durability while minimizing brittleness—designed for commercial and demanding residential mowing tasks where longevity and cut quality matter.

How do these blades stand up to factory OEM parts?

PPP XHT HD blades are specified to meet or exceed key mechanical properties of many OEM blades, with higher yield strength and improved impact toughness for fewer breakages and longer life. They are precision-sized to match the OEM mounting and cutting envelope.

• Replaces GRAVELY 03253800 with a 5/8" center hole for correct fitment
• Thickness .197", width 2-1/2", length 18" to OEM dimensions
• Higher Rockwell hardness (approx. 48–52 HRC) without brittleness
• Patented MARBAIN material for better wear and impact resistance

What performance improvements can I expect on my mower?

Expect longer edge life, reduced frequency of sharpening, and less deformation under heavy use. The lighter blade mass also helps quicker start/stop response with reduced stress on the PTO clutch, which can contribute to slightly lower fuel use over time.

• Longer intervals between sharpening and replacement
• Less bending and higher resistance to impact damage
• Reduced wear on PTO clutch and drivetrain components
• Potential for modest fuel efficiency gains due to lower rotating mass

Will these blades fit my machine and how should I confirm fitment?

These blades are manufactured to the same key measurements as the referenced Gravely part, but fitment depends on your mower's serial-specific configuration. Verify the part by matching center hole diameter, length, width, and thickness to your current blade before purchase.

• Center hole: 5/8" (0.625") — verify with caliper or factory spec
• Blade length: 18"; width: 2-1/2"; thickness: .197"
• Sold as a set of three identical lift blades
• Check mower serial/model or current blade stamping for OEM part cross-reference

How should I install and care for these PPP XHT blades?

Install using the mower manufacturer's recommended torque and orientation for lift blades—maintain balance to avoid vibration. Keep blades sharpened to manufacturer tolerances and inspect regularly for nicks or bends to preserve cutting performance and safety.

• Follow OEM torque specs and blade orientation markings
• Balance blades after sharpening to prevent vibration
• Inspect for cracks or severe wear before each season
• Replace blades in matched sets to maintain deck balance

Who is this for: This three-pack of PPP USA XHT HD 18" lift blades is aimed at landscapers, groundskeepers, and homeowners who require rugged, longer-lasting replacements for Gravely-style mowers. If you operate commercial equipment or maintain large properties and you want blades made in the USA with higher hardness and improved impact resistance, these blades are an appropriate upgrade—provided you confirm the 5/8" center hole and 18" length match your machine.
