Predator 3 USA XHT Blades Ferris 5061827 50619 50-619 44" Decks IS500Z & IS1500Z

Got these to replace oem blades in lieu of a sharpening on Ferris zero turn. Improved cut quality and chops blades into smaller pieces. Work great for me.

This is the second set of these blades that I’ve purchased for my Ferris IS 600 with a 44” mower deck. They work great and mulch just about everything from grass clippings to leaves. I would definitely recommend.

I bought these for my Ferris IS600. I’ve had these in service for a year now. We mow 3 acres of Bermuda and zoysia mix every week, and mulch leaves in winter. Try to keep the grass height at a consistent level, and avoid large sticks and tree debris. Went to sharpen these, and Wow! The edge is still sharp and dent free. Skipped the annual sharpening this year.

I found these blades when doing a search for new blades for my Simplicity ZT4000 B2444. The factory part number for the blades is the same for both the Ferris and Simplicity. I could not be more happy with the purchase of these blades. They work much better than the stock blades. Can now take full advantage of top speed while cutting. Old blades would always miss some grass, even when they were sharp. Good quality, made in the USA.

Standard heavy steel. These blades are hard to find.

Couldn’t find Gator blades for my Ferris IS500Z with a 44” deck so tried these. Work great. Much better than OEM for side discharge. Looks like they might also work well with the power bagger. I tried responding to someone’s question about fit for an IS600Z 44”, but forgot to mention the deck size on my mower so I just updated this review. Awesome blades, so I hope this helps.

The blades were easy to change out, fit like a charm, and cut cleanly without issue. Not sure what else you could want from mower blades.

I was so pleased to find these blades. My lawn dealer said that they didn’t make different blades for my mower. I guess you proved them wrong ! I was on my way to trade in my mower when saved by the Blade !
