Okay guys here is what happened with the bolts, and something new that I just discovered.
First off the bolts easily came off with my mechanic friends impact gun that he had his auto repair shop. It appears to me that there is no trace of "locktite" on the bolts, they were just tighten with their industrial strenght compressor and impact gun, torqed far above my compressor and impact gun capabilities. Still even though I feel that they may not have used locktite, they did intentionally impact the bolts to a torq strenght way above what is recommended in the owners manual. (see photo below of bolts, enlarge the picture, and give me your opinion on if you think locktite was used, or if because of the high torq strenght impacted by them, these bolts need to be replaced)
Here is the second thing I noticed last night. I decided to check on their other work, and while I know the air filter and v-belt was changed because they left the old ones on the mower, I know for a FACT they did not change the oil element they charge me parts and labor for. (which I now realize is my oil filter). I did NOT know until I looked in my manual, that what is called an oil element, is actually what I have always called an oil filter. (If you look at the photo of oil filter on my machine and the one in my hand, you will see that they are the same exact filter as the box of filters I use, also shown in a photo). The filter on my 44Z is new, because I changed it with my yearly oil change just 3 weeks ago, so the oil filter they say I needed that they said they changed was another lie, as it was not changed nor was it needed.
P.S. Also remember that an hydro oil change is recommended to be changed every 500 hours in my manual, and as you will see on my work order receipt (see photo) my 44z has but 163 hours on it. As for as the Hydro oil change being done, I do not know for sure, but the oil on the stick does look to be clear and clean.
