The dragging harnesses do help. Bottom line
Is 150 meters isn't that far, after removing
Intestines you should be able to move any
Deer that far if your in reasonable shape
With or without a dragging harness. Just
Pull a few feet at a time---no rush, take
Breaks.

You need to think more about how to get
To the right spot, so the deer are not likely
To cross your trail when they are heading your
Way and so that the wind direction will be
Blowing in the right direction to carry your
Scent away from the direction you expect
The deer to come from. Using a tree
Stand to get above ground level can
Help improve your ability to see deer
And decrease their ability to smell you.

Have as many stand sites set up as you
Can. Pick the right spot according to wind direction
Get to your stand well before daylight and
Stay until dark. Set up stands well before the season
Begins and don't frequent the area during the last
Month before the season. Try not to hunt the
Same spot more than a couple times a season.

Don't overlook the 11am to 1pm time frame,
Bucks know most hunters are out of the woods
And will move during this time,especially
Near heavy cover/bedding areas.

Happy Hunting
