Replaces 2 Simplicity Blades 38" Cut Deck 1704856 1704101 OregonOEM Blades

What It Is

This is a set of two replacement blades designed for 38-inch cutting decks on Simplicity lawn tractors, replacing OEM part numbers 1704856 and 1704101. They are compatible with OregonOEM blades and intended for medium-duty residential mowing.

Fitment & Compatibility

• Deck size: Only fits 38-inch cutting decks – measure your deck width to confirm.
• Model/brand fit: Specifically for Simplicity models using the 38" deck, such as certain Broadmoor, Regent, and Conquest series. Verify your tractor’s model number against Simplicity’s parts list.
• OEM vs aftermarket: OregonOEM is a known aftermarket brand; these match OEM specs for length, width, and hole pattern. Not universal – do not assume fit on other brands (e.g., John Deere, Craftsman).
• Measurements: Check blade length (approx. 19-5/8"), center hole diameter (check for 5/8" or 7/8"), and thickness (usually 0.1875"). Use a caliper to confirm before ordering.

Key Things to Know

• Quality: OregonOEM blades are heat-treated and hardened for durability, but single reviews mean limited real-world feedback – inspect for warping or burrs on arrival.
• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (set to 70-90 ft-lbs), and safety blocks. Always disconnect the spark plug.
• Common gotcha: These are sold as a pair for a 38" deck, but some Simplicity models use two blades; others use three. Check your deck blade count – if it’s a three-blade setup, this set won’t suffice.
• Balance: After installing, balance the blades on a balancer to avoid vibration and uneven cut. Unbalanced blades can damage the spindle.

Should You Buy It

This is a solid option if you own a Simplicity 38-inch deck tractor and need a direct OEM-replacement pair without paying dealer prices. The single review suggests early satisfaction, but with no volume feedback yet, it’s best for confident DIYers who can verify fitment and handle installation. If you prefer proven mass-market blades, consider Oregon’s standard 38" sets instead.
