John Deere R72 Belt Size FAQ

Is a close belt length good enough for the John Deere R72 deck?

The deck belt length found is 63 in (1,600 mm). Close is not the same as correct. A belt that is slightly short can overload bearings, while one slightly long can slip or fail to engage the blades cleanly

Why does 0.5 in (13 mm) belt width matter on the John Deere R72?

The captured deck belt width is 0.5 in (13 mm). Pulley grooves are cut for a matching belt profile. Wrong width can cause squeal, heat, poor blade speed or fast belt wear

Are the John Deere R72 deck and drive belt lengths close?

The deck belt is 63 in (1,600 mm) and the drive belt is 53 in (1,346 mm), about 10 in (254 mm) different. That is enough to treat them as separate belts when ordering

Official information note

Mistakes do happen. Belt specs can change by year, mower deck, pulley layout, serial range and regional parts catalog. Please check the operator manual, belt routing decal, old belt label and official John Deere parts catalog before ordering a replacement belt.
