Atco 24 drive chain tension adjustment

Enter a word or two to search the forum section and click the Search Forum button.

Hi all,

The drive chains on my Atco 24 are very slack, the mower works OK, but I can hear the drive chains slapping against the cover as I go..!!  It's not obvious to me how to adjust the tension to tighten them, perhaps they have stretched and need replacing, I am not sure.....can anyone advise ?

Many thanks

The intermediate sprocket on the two chains from the clutch shaft to the cylinder, moves in a slot and has an eccentric offset so with a combination of sliding and turning those two chains may be adjusted. You may need to remove the throw plate to get at the nut. 

Same goes for the intermediate sprocket between the two chains to the back roller. The nut for that one is up inside the LH side frame .
