unstable ground under the stabilizer causing the machine to list alarmingly when swinging a full bucket.
weak ground under the stabilizers that allows the machine to be pulled backwards nearly into the hole.
soggy ground under the machine that allows the stabilizers to both sink down full depth into the ground. Learning that raising them up too fast splatters mud over the operator...
Finding the supposedly "tight" machine that was purchased in fact needs bushings and pins. $$$$$
digging clay that sticks inside the bucket requiring the operator to get off and manually shovel it out of the bucket. each and every bucket...
finding cracks in the machine structure requiring tearing it down to bones and welding.
Finding the welds are not strong enough, requiring tearing back down and adding fish plate over the crack area.
finding even the fish plate cracks because the part was defective from the factory - requiring a 3rd tear down and total replacement.
listening to the wife, "I told you it would be cheaper to just replace it". grrrrr:laughing:
snagging a hose on a stump or branch and dumping $100 of hydraulic fluid on the ground.
whacking into stuff with the boom while moving.
discovering the machine is heavy enough to bend the ramps you are using to load it on the trailer.
