Reference
Specifications
- Fits cutting width
- 21 in. (53 cm)
- Blade style
- Standard bagging
- Blade length
- Not published by Toro on this part’s own pageIts product page carries no length, no centre-hole dimension and no thickness — and that page is where a dimension would be if Toro published one. Measure your old blade tip to tip. A 21 in. cutting width does not mean a 21 in. blade.
- Centre hole
- Not published by Toro on this part’s own pageCompare the centre hole and any drive-slot shape on your old blade to the replacement before fitting.
Selection
Choosing this part
The blade Toro lists for the 21565 Super Recycler in every range we opened — the earliest, a middle one and the latest of ten. Toro’s own name for it gives a 21 in. cutting width, which is not the width of the 22 in. mowers elsewhere on this site. Toro does not say whether the blades interchange, and neither do we.
