John Deere 717A Belt Size FAQ
Why can the correct John Deere 717A deck belt still slip?
The deck belt length found is 148 in (3,759 mm). Even with the right length, a weak idler spring, worn pulley groove or wrong belt path can make it slip. The part number and routing matter together
Should you buy the John Deere 717A belt by length only?
No. The deck belt width found is 0.38 in (10 mm). That is a narrow belt, so do not casually swap in a 1/2-inch belt unless the parts diagram says it crosses over. Too-wide belts can ride high in the pulley. Use length, width and OEM part number together where possible
Are the John Deere 717A deck and drive belt lengths close?
The deck belt is 148 in (3,759 mm) and the drive belt is 95.5 in (2,426 mm), about 52.5 in (1,334 mm) different. That is enough to treat them as separate belts when ordering
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.
