John Deere 112 Mower Blade FAQ
Should you buy John Deere 112 blades by length only?
No. The blade width found is 2.5 in (64 mm). That is a normal mower blade width range. Width affects airflow, lift and clipping movement under the deck. Use length, width, center hole and OEM part number together where possible
Should you buy one John Deere 112 blade or a full set?
The single blade number captured is AM31380, and the set number captured is GX20249 and GY20679. If one blade is bent from damage, one may be fine; if they are worn down, replacing the full set usually gives a cleaner cut
Which blade type should you use on the John Deere 112?
The blade type captured is high-lift and mulching. Use that against the captured fitment value AM31380. High-lift helps bagging/discharge; mulching blades need the right mulching setup
Official information note
Mistakes do happen. Blade specs can change by year, mower deck, spindle, serial range and regional parts catalog. Please check the operator manual, old blade stamp, deck tag and official John Deere parts catalog before ordering replacement blades.
