Trewey, I might have a lead on (hopefully) a cheapish Tirfor.
Seein as you are the resident hexpert on the subject.
Just wondering what sort of pull capacity I would need, they seem to range from 1200kg-4500kg would somewhere about 2500kg be about right?
Might need a lesson how to use the bugger without decapitating meself though

Yep 2500Kg will be fine. Don't forget that tirfors are rated for lift capacity Pulling capacity generally been double the lift capacity. Invest in a snatch block and you will double the pull capacity or more importantly half the effort required to pull your landy out the mud..

Make sure it is a proper tirfor and not a turfer or comealong as most of the ones on ebay are called. they are ****e and will only pull about 3to 4ft before you have to stop re-rig everything and start again..

Cheers Red,
Should be a proppa Tirfor, may take a while to get hold of it but it should be cheap (Not as cheap as Trewey's) will just need to learn how to use it.

Mine's a 3.2 tonner. It's great, but it's fookin heavy.
A 1.6 tonner will get you out of most situations for less than half the weight.
A 2.4 tonner will be more than ample.

Make sure it comes with the proper cable - Tirfor cable is knitted differently to standard steel cable, to resist crushing by the mechanism. It also has a tapered end to feed through the mechanism.
Length of cable is a compromise between how far you can pull in one go and how much weight of cable you've got to carry around. Mine's 20m, which seems a reasonable compromise.
