Some days it's just one thing after another!
I think there's a difference between working on something because one enjoys tinkering versus working on something because one has to. For me, I was tired of a lifetime of messing with tractors just to get them to work to get the lawn mowed. With an older (worn out) tractor, I would have to fix the tractor (a project in itself) to be able to mow the lawn (another project) and hope the tractor wouldn't break mid mowing (tow back to house- another project) and fix it again(another project). That's a lot of projects.
Out of frustration and necessity, I finally broke down and invested in a newer john deere (not department store stuff).
Now, I can go mow the lawn when I want, and I can go tinker on the old tractor when I want. The new tractor makes the old one enjoyable, because the old LGT is now a hobby on my terms. The new tractor has let me get the old tractor to the point where it is semi-dependable again. It's fun to take the old tractor out and start using it on real projects, but I know if something goes south, I can always get the new one and finish the job if needed.
