Should you buy John Deere 1445 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
What is the difference between the John Deere 1445 blade number and blade set number?
The captured single blade number is M154202, while the captured blade set number is TCU51118. Use the single blade number for one replacement and the set number when replacing the full deck set
Which blade type should you use on the John Deere 1445?
The blade type captured is high-lift, mulching, bagging, and 3-in-1. Use that against the captured fitment value M154202. 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.
