Hi!

i have the mod tree harvester installed i also have collective but when i try to chop down a tree nothing happens

Did you also try crouch chopping the tree?
Or did you change the config?

crouch chopping did solve my problem

Good to hear!

You can always change it in the config file if you want.
Go to the config file and change this option from false to true:

// If enabled, tree harvesting works when not holding the sneak button. If disabled it's reversed, and only works when sneaking.
"treeHarvestWithoutSneak": false
