John Deere D105 Belt Size FAQ
Is a close belt length good enough for the John Deere D105 deck?
The deck belt length found is 104 in (2,642 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 D105 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
Which John Deere D105 belt needs more careful length matching?
The deck belt is longer here: deck 104 in (2,642 mm) versus drive 95.5 in (2,426 mm), about 8.5 in (216 mm) different. Do not cross-match them just because both are mower belts
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.
