I've pulled an 8' behind 2 cylinder crawlers a great deal, in both snow and dirt with no problem. 350 will pull a 10 foot easily. As far as a 12 foot, probably same song, just depends on how fast you want to pull, and how much dirt you want to carry.

Re: 350 steering link
Deere's current replacement for the steering clutch adjuster is a Heim joint. It is utter impossible to adjust, it is not a suitable part. Ive had the argument with DTAC, they don't care, they feel it is the right part, so I gave up, started putting together my own joints.

Re: 56, 420, 5 roller 4 spd
It will bolt up, you will need to change radiator, hoses, throttle rod bracket, fan, fan support, not sure what belts you are going to need, and other stuff I am forgetting about. You will also be really disappointed in the power compared to a 420.

Re: 56, 420, 5 roller 4 spd
I have little to no faith in Helicoil. Just pulled apart a 440 that had a Helicoil in the trans, and the Helicoil just pulled out and did nothing. I prefer the full threaded inserts like Keensert, Timesert, and plenty of other brands. I have done several with exactly what you have on yours. They are...

Re: Diesel fuel additives
We had an HD3 Allis crawler that had a horrible case of algae. It will literally grow through a filter and continue its way to the pump. I have never worked with something so miserable in my life. I set one of the filters on the drawbar, and the black ooze ran down onto the drawbar. Later on I got s...

Re: Diesel fuel additives
For cold weather as an additive, I use Power Service, if I screw up and am in trouble, I use a product called Melt Down. Similar to Power Service 911, but I feel it works much better. As a general additive, if you have a rotary Roosamaster pump, then I use TCWIII outboard motor oil. I don't have it ...

Re: Thinking About Buying a 1967 JD 450 Dozer
I would echo what Leonard said. My bet is trans is slipping, he knows it, that's probably why he abandoned it. By it by the pound for a parts machine.

Re: Locknuts on connecting rod bearing cap bolts?
It is kind of personal preference. I personally have put very few back on. They certainly don't hurt anything or Deere wouldn't have used them to start with. Lots and lots of higher HP, higher RPM engines that never used them.
