I had a 50 hour service completed last fall at the dealer on my 1025R which included a hydraulic fluid change. I did not use the tractor much over the winter, some firewood hauling and road grading, but now that summer is here I have mowed the grass at least 3 or 4 times. I decided to give the tractor a good cleaning and as I was blowing off the dust before washing, I discovered the following under my seat:
The yellow arrow is pointing to where I found my oil fill screw cap and the blue arrow is where it should have been. Notice all the dust around the hole? Obviously when the technician finished the maintenance, he forgot to replace the cap and it has been sitting under my seat for more than 6 months with the reservoir open to the environment. I know there would not have been any water contamination as I store the tractor in the garage, but I suspect some amount of dust or dirt has managed to get in. I pulled the dipstick and the oil was still clear and bright (Navy terms), so the filters are obviously doing their job.
Besides showing this photo to the service manager, should I be concerned about any long term issues? Does it warrant a fluid change? I'm at about 86 hours at the moment. I'm kicking myself for not noticing, but with the seat down, it was not apparent. I suppose at a minimum I could pull and clean the oil pump suction screen and replace the transmission filter.
