Track Tension

[Andy]

After rebuilding both finals and upper idlers on the 420c five roller, the tracks are back on and adjusted with 3/4 inch sag between the upper and front idler as per the jd manual. In your experience, is this the proper tension or should they be run a little looser or tighter? I plan to re-adjust the tension after I walk it outside and run it back forth a few a times.
Thanks for any replies in advance.

Hi: JMHO
I use the JD specs. This allows for the appropriate amount of shock absorption as the tracks are stressed and yet keeps them on. If you run them tight, you accelerate wear; if you run them loose, you are asking for a more easily thrown track.

Track tension is dynamic: run them a bit tighter if working on side hills and in "ledgey" terrain; run them looser if you don't have snow pads and you're in snow or mud that might build up between the sprocket and pads causing over-tensioning.

Again, just one persons opinion. Good luck. Paul

I always lean towards the loose side myself, but like Paul said- depends where and how you are working...that said- they never seem to loosen much from where you adjust em last, but they sure can tighten up in a hurry. Here in NW Oregon we can go from dry sunshine to fog to snow to rain to hail to back to sunshine all in the same hour! 3/4" sag is great for dry or moderate conditions, not so great for mud and snow.

Good advice, thanks guys.
