I've been awful fortunate throughout my career, I usually get to clean up the messes of others and I get to learn from their misfortune so I don't do the same. However my biggest blunder to date happened a few weeks ago, I was in my cherished M318D and we just started a bridge job and we were clearing and grubbing. Down along the the creek bank was some trees I had to pull out and clean up, so I went down over a 2:1 about 10 feet high. I checked the ground before going down and it seemed hard like any creek gravel area is, I proceeded to work for about 10 minutes and all of a sudden it was like I fell through ice. I ended up punching through about 1' of frost and into some silt, to about the top of the tires, no big deal really. I pulled myself 10' before I decided it was best to get a dozer to help. It got to the point where everyone started throwing their $.02 in, do this, do that and blah blah blah. A couple guys wanted me to stuff some trees in there to act as a courderoy road but I said no as to all the branches and stuff getting into the driveline and hydraulic hoses and causing more damage. So we hooked a 930 and a D3 together and got 20' and she wouldn't go no more. So at this point the Superintendent wanted me to stuff some medium rip-rap in there and try to get up on it, I himmed and hawed and they browbeat me into it, I wasn't crazy about the idea as I've been under these machines and know how delicate they are underneath. However at this point I said, hell lets try it. We got a few more feet then she got high centered on a rock, the rock drove the drive shaft into the gearbox above it and broke the whole works. So now we're screwed, cutting the drive shaft and hooking to a wrecker. It was a long afternoon, I guess I should have stuck to my guns and said no to the rocks but hindsight is 20/20. We drug it onto the lowboy and sent her to main shop, 'twas a sad day for sure. I sure did feel like hell for a few days afterwards, but I must say, the owner of the company came out a few days later and basically said you can't make an omelette without breaking an egg, we shook hands, I said I was sorry and we moved on. He sure is a stand up guy, there's no doubt about it.
