your thoughts here. how useful would heavy equipment be in a shtf scenaio? i would think very useful myself. from what i know of all CATS use the same key cut,they do where i work at least, so if you had a CAT key you would have access to any caterpillar tractor around your area. the same for hyster as far as i know. im not sure about the others. but all you would need is one key. now being able to operate is another thing that really just takes a little intelligence and time but not much on the time part. i run these every day, they arent hard! just figured id get some thoughts on it an mybe give yall a big prep for very little cost as hevy equipment is all over the place where i live. it would be hard to hide if you were trying to be silent or hid from others tho. thats the only downside i see. tractors have multiple uses so depending on which you were able to snag would have barring on what you could do. just a thought, all you need is few keys! small prep with possible huge payoff!!
