John Deere F620 Mower Blade FAQ
Why can the right-length John Deere F620 blade still be wrong?
The blade length found is 21 in (533 mm), but length alone does not confirm fitment. Center-hole shape, blade offset, sail height and deck size can all change fit
Does 3 in (76 mm) blade width matter on the John Deere F620?
Yes. The blade width captured is 3 in (76 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
Why does the John Deere F620 blade center hole matter?
The captured center-hole detail is 0.91 in (23 mm). If the hole shape or size is wrong, the blade may not seat correctly on the spindle even if the length looks right
Which blade type should you use on the John Deere F620?
The blade type captured is high-lift, mulching, standard, bagging, and 3-in-1. Use that against the captured fitment value 21 in (533 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.
