i want to create an animal trail without using bait or lure?

If you going through long grass walk a trail in and out of where you are trapping. Pack it down good. Walking a trail is more natural than cutting one.

A weedeater will create whatever trail you want through grass.

I raked leaves to my stand one year to cut down on noise. Huge mistake on my part, lol. Everything under the sun used that trail straight to my stand. So basically the critters liked walking without making noises as well. I then raked a trail about 25-30 yards from my stand and it paid off during archery season.

Round up.

so if i cut a rough trail then walk it abunch to and from a field or whatever animals should start using it?

Yes. Make it leading into ur skinning shed and u shouldn't even need to set a trap next fall

Animals need a reason to follow or make a trail.
Animals follow the path of least resistance as well as the shortest distance between two points,when they have a reason.
Once you provide the reason for the animals to want to go someplace,they will follow pre existing trails (human trails,rabbit runs beaver skid trails, etc) or make their own.
There are many reasons animals make trails,one of the easiest to find are beaver crossovers,and otter trails cutting off hairpin bends in oxbowed creeks etc.

I have 3 carcass dumps on three different property's. There are 3 trails going to each dump site. I go in the early summer and round up all these trails. Then i go back and do the same thing In the fall. I created all these trails to my advantage, I want those critters going where I want them to go.

As stated above...a weedeater will work good for this...followed by a leaf blower...then glyphosate herbicide..

Ditto on the weed eater.
