John Deere 245 Belt Size FAQ
What should you watch when fitting a 66 in (1,676 mm) deck belt on the John Deere 245?
A 66 in (1,676 mm) deck belt leaves little room for sloppy routing. This is a mid-length belt run, so routing and idler position still matter more than just matching a close-looking belt. Before blaming the new belt, compare the belt path to the routing decal and make sure it sits on the correct side of each keeper
Should you buy the John Deere 245 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 245 belt needs more careful length matching?
The drive belt is longer here: deck 66 in (1,676 mm) versus drive 74 in (1,880 mm), about 8 in (203 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.
