Cost me $60 in parts and a couple hours of time fixing the front hubs on my tractor. Most of the wear and tear came from having to deal with roads torn up by feral pigs.
As you would with a common cockroach, never give a feral pig a pass.
Tell me about it. Couple of summers ago...moving some tree trunks and limbs with the tractor, I turned sharply to the left and the right front tire drops down into a hole a hog had rooted out. Soil is sandy-loam and pretty soft...so the tire digs in and the entire wheel and tire pop off the spindle. Spindle and spindle nut stripped from the sudden stop. Big International Cab Tractor way out in a pasture, down and out. 100 degree day when I finally got the parts. Miserable time trying to get the front end jacked up and the parts replaced.
THIS summer, I am cutting across a different pasture to go check some cameras and the left front tire of my Ranch Vehicle drops down into a rooted up hole (you can't see them when the grass is high). I heard a 'pop' and when I went to turn left on the road, my vehicle just kept going straight! Get out...and sure enough the tie rod is dangling there! Dead in the water again. A mile from home, Wife not answering her cell phone. Get to walk back, cussing Hogs.
THAT is why I am willing to stay up late, or get up early to go and kill the pests. Big ones, little ones, doesn't matter, they are shoot on sight!
