John Deere Z970A Mower Blade FAQ
Should you buy John Deere Z970A blades by length only?
No. The blade width found is 3 in (76 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
Why does the John Deere Z970A blade center hole matter?
The captured center-hole detail is 1 in (25 mm). If the hole shape or size is wrong, the blade may not seat correctly on the spindle even if the length looks right
What is the difference between the John Deere Z970A blade number and blade set number?
The captured single blade number is UC15157, while the captured blade set number is TCU21475. Use the single blade number for one replacement and the set number when replacing the full deck set
Can you swap John Deere Z970A blade types?
The blade type captured is high-lift, mulching, standard, and 3-in-1. You can often choose a different style only if it fits the same deck and spindle setup. Use UC15157 as the fitment starting point
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.
