The simple truth is that the person that preps your new tractor is almost always the lowest man (kid) on the totem pole. It simply is not feasible to put a top notch flat rate mechanic on this job, (you would not want the bill). These are the type of tasks that you hope your newbe can perform, (being that they are provided with a simple to follow check list). However, I can guarantee you that almost everyone of the tractors has something that gets overlooked. And the number one thing is grease fittings that are not greased. If you check hard enough I bet you will find others. There are a number of grease fittings on these machines that are very easy to over look. They missed 3 on mine.
The moral of the story is "If you want something done right......."
