Troy Bilt Chipper 12 Chipper Shredder Flails/Hammers Troy-Bilt 1756904, 1915700HT and 1915700ZMA

I haven’t use machine much since replacement but for the price and the problem locating factory replacements, even if they last 6 years vs 8 yrs you can’t go wrong.

Would buy again without an issue

So I struggled to get the old blades off. After removing the pins with a punch, the roller or whatever it's called would not come out. I used heavy hammers, soaked it in break free, tried for a few days. Then while searching harbor freight for a arbor press, I found a air hammer for $10. Bought the attachments with a punch looking one in there and that's what got the rollers out finally. Just fyi for anyone struggling like I did. Got it back together and shredded and chipped for hours and got the job done. Engine didn't struggle because of nice new blades.

These blades are not an exact replacement they are much lighter gauge than the factory parts leaving a lot of play between them on the shaft. I would have returned them if it was a simple job but I was too far in. It remains to be seen how long they last.

went through all the weeds and leaves I had piled up in no time

Hammers are fine
