I lost count of the hours i spent on it, the parts were bought 8 or so years back off a member that used to be on this forum. I think they were around 8k. They quickly added up.
This machine was bought to repair and keep, along the way, i got hold of an S150 that is now my favourite
My main use for these machines that i have owned over the years were to repair and move on to a new owner. I also used them to move dirt around at my parents place, so they are sort of tested with that, then sold.
The S150 got a bit of work for my cousin that raised his house, it needed earth works done under it, not sure how many hours, but i'd guess 30 or so.
