I just got my TLB in december and I'm just over 80 hours so far. I figure I'll do about 200 hrs a year for the first 3 years and then a lot of the projects will be done so I will be down to 70 ish hours a year after that. I don't use the tractor to mow, I have another unit for that. Mowing would probably be 150 hours a year.
We have 10 acres and some livestock. The land is partly treed, partly hilly, partly flat, part wetland and a pond (we are lucky to have such a great lot).
I use the FEL more than anything (regular bucket, manure fork and pallet forks) and also tow a fair bit with the tractor. The BH does not get a ton of use but boy is it handy to have available. I also have a box blade that makes me a bit of money doing people's laneways as well as my own, particularly in the winter to smooth the snow.
Love the tractor, don't know how we lived without it. I can find something to do with it almost every day. If I rented, sure I could do the big projects on a tight timeline but a LOT of other stuff would simply never get done. If you can afford one, a nice BX or Kioti CK would make you a very happy person for a very long time. Oh yes, blue, red, green, you'd do great with one of them too - don't want to offend the other colors.
