00450300 Hi Lift Mower Blade Compatibles with 52" Deck, 00273100 High Lift Blade Compatibles with Gra vely Pro Turn 152 w, Pro Master 152Z, Replaces for 04916400, 038-3000-00, 3 Pack

What It Is

This is a set of three high-lift mower blades designed for 52-inch cutting decks, primarily for commercial-grade Gravely Pro Turn 152 and Pro Master 152Z zero-turn mowers. The aggressive lift pattern improves grass discharge and bagging performance, especially in thick or wet conditions.

Fitment & Compatibility

Before purchasing, verify your deck is exactly 52 inches (center spindle to center spindle). These blades replace OEM part numbers 04916400 and 038-3000-00. They are compatible with Gravely Pro Turn 152, Pro Master 152Z, and select other 52-inch deck models that use the same blade pattern. Measure your current blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and thickness (about 0.25 inches). Confirm spindle hole pattern matches your deck’s blade mounting studs. Not for 48-inch or 54-inch decks.

Key Things to Know

• Quality: Heat-treated steel with a protective coating; holds edge well in normal use but may dull faster in sandy or rocky conditions.
• Installation difficulty: Moderate – requires lifting the mower, removing old blades (use anti-seize on bolts), and torquing to manufacturer specs (typically 70–90 ft-lbs). Safety glasses and jack stands recommended.
• Common gotchas: High lift increases engine load and may reduce run time; ensure your deck’s belt and pulleys are in good condition to avoid slippage. If you mow very dry, fine grass, high lift can cause clumping – consider standard blades for that use.
• Pack includes: Three blades, but no hardware (bolts/washers sold separately). Check your existing hardware for wear.

Should You Buy It

Ideal for Gravely Pro Turn 152 or Pro Master 152Z owners who need maximum grass lift for bagging or discharge in tall, damp, or thick turf. Not recommended for dry, fine grass or if you prefer a smoother cut with less clumping. At $39.99 for a three-pack, it’s a strong value compared to OEM replacements.
