Larry: Your part in this discussion has me convinced you know very little about Farmalls. Especially that last comment telling us a Farmall 130 is 60hp. Took bit of time, did a little cruise through the archives, your questions of 18 months ago confirm what I am saying. Just 18 months ago you were asking very elementary questions about Farmalls. About the only responces you gave involved what they sold for at the last auction, I found no technical advice. Checked out prices on piston and sleeve kits with gaskets. Farmall 130- $100. per cylinder, Farmall 656- $125. per cylinder, 806 and 966 $200. per cylinder. Took a glance at other items and the spread is about the same. Basically this agrees with my many years of record keeping. You always show greater profits when underpowered on the farm. That little 130 gasser is going to run about 4,000 to 5,000 hours on a set of pistons and sleeves. Diesels on the other hand will run 10,000 hours on a set of pistons and sleeves. Most of the diesels I've seen do 10,000 hours clocked those hours very quickly, about 800 or more yearly. I have seen a lot of diesels doing 300 hours per year require pistons and sleeves every 5,000 hours. Looks to me like you size the tractor to the work. Another matter one has to be concerned about with 66 series and later diesels is cavetation with these wet sleeve engines. Water filters will slow it down, however they will not eliminate cavetation. Without the filter the sleeves will be done in 8 years and the filter it will double t0 16 years. I personally think these 66 series engines could reasonably go 15,000 hours between rebuilds, but the tractor must be clocking 1,000 hours per year. Highly unlikely bush hogging 11+ acres per year. So why don't you just leave the advice on which tractor to buy, to the guys who bought these tractors new 30 to 40 years ago, kept meticulous records on them for many years. I always asked a mechanic for technical advice, but I never asked him to do my record keeping.
