I’d go full size rope puller kit over micro pulleys. May as well make work easier

Pulling with the mini.

Have mercy... is that a 7:1 being pulled with a mini?
You straightening out that screwy tower in Pisa or something?

What is the swl and model of triple pulley?

 

[flushcut]

It is a 7:1. I figured 20,000lbs of available pull. Well beyond the SWL of the tripples rated at 30,000lbs MBS. The tree was a big silver maple and was rigged to go my way and no other. It was faster to flop it than to rig down, over a fence, two garage sheds, garden, and three properties. The tree had 40yds of chips.

That system could use up a long ass piece of rope I’ll bet.
Those are CMI pulleys?

Ever watched tom old fart RIP out stumps with power pulls on tractor.. awesome shit... I'm always amazed at how well trees work for anchor points and generally trust them well, but evaluation and attentiveness to anchors should always be considered. After rains or trees with wet "feet" can slip much easier out of place. Albeit rare probability just a consideration that I dont feel should be over looked when pulling with heavy power

The lime green rope is 300' of 9/16" dyneema/poly hybrid, yes CMI.
