Caltric 42" Replacement Lawn Mower Blades (2-Pack) for Poulan / Husqvarna 42" Decks — Balanced, OEM-Style Fit

These are two replacement 42-inch mower blades from Caltric designed to fit a wide range of Poulan and Husqvarna lawn tractors and similar models. Caltric supplies this two-blade set as a direct-fit, aftermarket replacement for many mid-size riding mower decks. Each blade is stamped and shaped to match OEM cutting profile and mounting hole patterns so you can restore cutting performance without buying an original-brand blade. The listing includes model cross-references and OEM part numbers so you can verify fit before ordering.

Whether you’re replacing worn blades or keeping a spare set on hand, these blades are machined for consistent balance and a standard edge geometry that works with bagging, mulching, and side-discharge decks. The set is offered as two identical blades and is intended to be used as a matched pair to maintain deck balance and reduce vibration.

Which mower models will these Caltric 42" blades fit?

These blades are compatible with many Poulan and Husqvarna tractors plus a range of related OEM part numbers used by brands such as Ariens and Craftsman. The compatibility list includes popular model series and multiple stamped OEM references to make cross-checking easier.

• Fits Poulan models like PP175G42, PP185A42, PP19A42 and many PB/PO series with 42" decks.
• Fits Husqvarna/Lawn Tractor models including LT, LTH, YTH and YT series that specify 42" blades.

How do these blades affect cutting performance?

Replacing dull or damaged blades with a matched pair restores clean, even cutting and reduces tearing that stresses turf. Properly balanced blades also help lower vibration and wear on spindle bearings, improving deck longevity and operator comfort.

• Sharp, uniform cutting edges produce a neater finish and healthier grass clippings.
• Matched-pair replacement keeps the deck balanced, minimizing vibration and hardware stress.
• Standard blade profile works for mulching, side discharge, and bagging decks when used correctly.
• Durable steel construction resists bending under normal use.

What should I check before ordering these replacement blades?

Confirm your tractor’s deck blade length, mounting-hole pattern, and any manufacturer-specific stamped part numbers. Visual comparison of blade shape and hole positions with the pictures in this listing is recommended to prevent misfit.

• Measure blade length (tip-to-tip) to match the advertised 42" size requirement.
• Compare center hole and mounting slot positions to your existing blades.
• Match OEM part numbers listed in the compatibility notes when possible.
• Order and install blades as a pair to maintain deck balance.

How do I install and maintain these mower blades?

Installation follows standard mower blade replacement steps: raise and secure the mower, remove old blades, mount the new blades with correct rotation direction, and torque fasteners to manufacturer specs. Regular sharpening and inspection extend blade life and performance.

• Always disconnect spark plug and secure mower before working under the deck.
• Install blades so the cutting edges face the correct mowing direction indicated by the deck.
• Torque blade bolts to the tractor manufacturer’s recommended specification.
• Inspect blades for damage and sharpen as needed; replace if bent or cracked.
