John Deere 170 Belt Size FAQ
Is a close belt length good enough for the John Deere 170 deck?
The deck belt length found is 95 in (2,413 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
Should you buy the John Deere 170 belt by length only?
No. The deck belt width found is 0.5 in (13 mm). That is the common 1/2-inch belt width range. Still match the OEM number because the belt angle, fabric wrap and effective length can differ. Use length, width and OEM part number together where possible
Are the John Deere 170 deck and drive belt lengths close?
The deck belt is 95 in (2,413 mm) and the drive belt is 87 in (2,210 mm), about 8 in (203 mm) different. That is enough to treat them as separate belts when ordering
What is the risk with the John Deere 170 drive belt part number?
The captured drive belt number is M144202. If the width is missing, a cheap cross-reference can still be wrong even when it claims to replace the OEM belt
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.
