2 hrs is 'too far'? Balderdash! There are a whole lot of people that spend 2 hrs just commuting to work every day.
As for counting the cost of the trip as a part of the cost of the tractor/implement...I guess that's up to the individual.
Personally, I don't. Especially when I take the wife with me as she likes the traveling and seeing new country.
My last trip to pick up a tractor and some attachments took roughly a week, and was very close to 1700 miles in a motorhome that gets 7Mpg. Adding in the gas used for the generator when we were parked, lets call it 1700 even. Now gas was @ 3.30 at the time so that was $800.00 in gas alone. Add $130.00 for the trailer rental, now we are at 930.00. We were gone for a week, so add in $70.00 for meals/snacks, and we are at $1,000.00 just for the trip. That's what I paid for the tractor. The attachments were $525.00.
I did bring back a motorcycle for a fella who paid me $200.00, so my total out of pocket was roughly $2,325.00.
Now, for that $2,325.00, I ended up with an extremely rare Bolens Large Frame, a Haban Flail-Mo for the Tube Frames, a MacKissic rear mounted sprayer for the Tube Frames, and a VERY nice Brinly planter with 8 seed plates.
All in all I think it was well worth it, plus I got to meet some nice folks and see some nice countryside. Not to mention that the wife had fun as well, and as we all know...when momma is happy everyone is happy
