SK-2 Reel Mower Sharpener Compatible with Earthwise Reel Mowers, Lawn Mower Blade Manual Sharpener for Most Push Reel Mowers

What It Is

The SK-2 Reel Mower Sharpener is a manual lap-grinding compound kit for sharpening the reel blades and bed knife on push reel mowers. It is marketed for Earthwise reel mowers but works with most standard push reel mowers (non-motorized) to restore cutting performance.

Fitment & Compatibility

• Brand fitment: Designed for Earthwise reel mowers (e.g., models 1815, 2015, 2515) but also fits most brands with 14-20 inch cutting widths, including American Lawn Mower Co., Great States, Scotts, and Craftsman manual reel mowers.
• What to check before buying: Ensure your mower has a manual reel (not a powered/spin-type blade). The kit works with reel-to-bed knife contact; if your mower has a fixed bed knife with no adjustment screws, it may not work effectively.
• Measurements: The included lapping compound tube is standard size; the kit contains a small brush and instructions. No specific deck size restrictions—works on any reel mower where you can access the reel and bed knife.
• OEM vs aftermarket: This is an aftermarket accessory, not an Earthwise OEM part. It will not include mower-specific fitting adapters.

Key Things to Know

• Installation difficulty: Easy—no disassembly required. You apply lapping compound to the reel, rotate the reel backward by hand (or with a drill), and readjust the bed knife clearance. Takes 10-15 minutes.
• Quality: The compound is gritty (fine aluminum oxide) and works for light sharpening. It will not fix bent blades, deep nicks, or severely dull edges. For heavy wear, you still need a professional grind.
• Common gotchas: Do not overtighten the bed knife screws during adjustment—you can warp the blade. Also, the kit only sharpens the reel-to-bed knife interface; it won’t sharpen the reel’s side edges or the stationary blade’s bevel if it’s chipped.
• Mess factor: The compound is greasy and stains. Use gloves and lay down newspaper.

Should You Buy It

Buy this if you have a manual push reel mower that’s lost its cut quality but has no major blade damage, and you want a cheap, quick fix to extend sharpening intervals. Skip it if your reel has bent blades, deep gouges, or you need a pro-grade edge—this kit is a maintenance stopgap, not a restoration tool.
