Yep, what Tom said. Pruning is good though and improving drainage almost is almost always a positive thing to do.
I favour bush-hooks over secateurs, but then again I've brashed through the middle of FE plantations (with permission ;-). However, they do tend to be perceived a little bit more in the "offensive weapon category".
I'm not so sure about a rake though. If it's to clear trail debris and organic then a boot edge / stick is often sufficient. Once you get rid of some overhanging trees and other vegetation the amount of stuff landing on a trail usually decreases.
A chillington hoe / Azada is a great piece of kit for a lot of trail work but you'd probably struggle to carry one of those as well 😉
