John Deere LA150 Mower Blade FAQ
What should you check when fitting a 21.34 in (542 mm) blade on the John Deere LA150?
A 21.34 in (542 mm) blade needs the right center hole, lift style and deck clearance. That is a common lawn tractor blade length range, but it still needs the right center hole, sail/lift shape and deck fitment. Spin the blade by hand after fitting to confirm it clears the deck
Does 2.75 in (70 mm) blade width matter on the John Deere LA150?
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 LA150 blade or a full set?
The single blade number captured is GY20684 and GX21380, and the set number captured is UC20448, TCU21475, and UC22010. 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 LA150?
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.
