TENGMUJX 54" Deck Mower Blades for John Deere ZTrak & X Series — 54-inch, Hardened Steel, 7/8" Center Hole

These are direct-fit 54" replacement deck blades from TENGMUJX engineered to match John Deere OEM fitments and restore cutting performance.

If your 54-inch mowing deck has dull, bent, or worn blades, these TENGMUJX blades are sized and drilled to replace John Deere part numbers such as M136195, M135334, and others. Manufactured to the same center-hole and length specifications, they let you refresh your deck without buying an entirely new cutting assembly. The blades are made from hardened steel and finished to resist corrosion so you can get consistent results across wide residential and light-commercial lawns.

How will these blades fit my John Deere ZTrak or X series mower?

• Length: 19 inches; width: 2.5 inches; thickness: 0.236 inches
• Center hole diameter: 7/8" for standard spindle bolts
• Designed to replace M136195, TCU30316, M135334 and similar OEM numbers

What cutting performance and durability can I expect?

TENGMUJX blades are heat-treated and ground to hold an edge longer than untreated steel. They offer predictable cutting and mulching behavior when properly installed and maintained, helping produce a uniform turf finish.

• Corrosion-resistant finish for longer storage life
• Replace in matched sets to maintain deck balance and cut quality

How easy is it to replace these mower blades myself?

• Remove deck and blades per your mower manual, block blade, unfasten center bolt, swap blades, and torque to spec
• Replace all blades on the deck at once to keep balance
• Inspect spindles and bolts for wear during replacement
