Stens 345-156 Medium-Lift Mower Blade, 20 in
The Stens 345-156 medium-lift blade is listed as a replacement for Toro Groundsmaster 580D mowers. Its 5/8-inch center hole and stated 20-inch length make exact fit and part-number matching important before purchase.
At a glance
- Medium-lift replacement blade listed for Toro Groundsmaster 580D.
- The listing identifies three Toro replacement numbers: 69-6920, 69-6920-01 and 69-6920-03.
- A 16-foot deck is stated to require 11 blades, so this listing describes one blade rather than a complete deck set.

Frequently asked questions
How many blades are indicated for a 16-foot deck?
The listing says 11 blades are required for a 16-foot deck. The included-components detail identifies one medium-lift blade, so this item is not presented as an 11-blade set.
Which Toro part numbers does this blade replace?
The listing names Toro 69-6920, 69-6920-01 and 69-6920-03. Confirm the mower's required number and fitment before purchasing.
What center-hole size and blade dimensions are listed?
The blade specifications state a 5/8-inch center hole, 20-inch length, 2 1/2-inch width and 0.250-inch thickness. The separate item-dimensions field gives a 19.85-inch length, so check the listing details and mower requirements.
