John Deere 115 Mower Blade FAQ
Why can the right-length John Deere 115 blade still be wrong?
The blade length found is 21.34 in (542 mm), but length alone does not confirm fitment. Center-hole shape, blade offset, sail height and deck size can all change fit
Does 2.75 in (70 mm) blade width matter on the John Deere 115?
Yes. The blade width captured is 2.75 in (70 mm). That is a normal mower blade width range. Width affects airflow, lift and clipping movement under the deck. A different width can change airflow, cut quality and clipping discharge
Should you buy one John Deere 115 blade or a full set?
The single blade number captured is M144202, and the set number captured is GY20850. 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 115?
The blade type captured is high-lift, mulching, standard, bagging, and 3-in-1. Use that against the captured fitment value 21.34 in (542 mm). High-lift helps bagging/discharge; mulching blades need the right mulching setup
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.
