I've been dithering about buying a high lift farm jack type device for a

pulling as you tend to use a lot of the active length in taking up slack.

also have a 5 tonne chain and ratchet winch which is much more
controlable.

Hi Lift jacks do require a lot of care in use because of their inherent
instability.

They can be lethal if not used correctly particularly when lowering the
load.

I have both a high lift and a Tirfor winch. The Tirfor is by far the best
tool for pulling anything. I bought it for self recovery but have never
needed it for that. I have however had good use out of it for pulling up
tree stumps, positioning a mobile home, pulling trees in the right direction
when felling, and have used it as an engine hoist.
