My 16 year old son is looking for a tractor to restore for FFA and he is wanting to do a 2 cylinder deisel. He also likes to pull at the tractor pulls and i was wondering what everyone thought was the best 2 cylinder to pull with and why. I am looking for an electric start. We are trying to stay away from the pony starts. Looking at the 730,720 electric start or 830 or any suggestions. Thanks, Scott
 
An 830 is not that much heavier than a 730 and is a lot easier to make HP with. The 830 would cost more up-front, but it's easy to get under 7500# and easy to make over 100hp. At the same time, if you are going to stick to classes with a 3mph speed limit, Roger Marlin can make a 730 very competitive at stock cid. I may know where there's a good 830 if you're interested.

720/30 are competitive at stock ci. With tight motor and some injection work they make good power.
Myself like the creeper gear in the 720/30's. I generally run 2nd gear in my 720 but it gives you the option to shift down if your pulling heavy or have a real heavy track.
You could start with an 830, bigger cubes, more power but so is the purchase price of the tractor. You can get a $4000 or less 720 diesel and stick lots of cash into it.
I can get you lined up with a pump guy in Texas, email me. gpuller at hotmail dot com.
 
I am a ih puller but I have saw a 435 john deere puller at about 3,100 rpms n with some other work u can have a good 4500 n 5000 pound puller puting out 60hp n will b n the top
 
A 2-53 is certainly a cheaper build than a 70/720/730. Easier to trailer the tractor too.
435's are pricey similar to a 320. Finding a 435 without a smashed or missing nose casting can be a challenge.
The almost identical 440ID industrial wheel tractors sell cheap enough.
60HP pto is doable at 2400rpm if built right.
4500lb class is easy. A stripped 440 would make the 4000lb class.
435/440 are nose heavy. Need a beefy drawbar in the long position on wet or loose tracks.
 
Roger Marlin (Two Cylinder Diesel Shop) and David Marlin (2 Cylinder Plus Tractor Parts) are both near Conway, MO, but their businesses are unrelated. Roger is who you want and he can be reached at the number for the Hook Magazine (417-468-7000).
 
I can see that you are talking about a horizontal JD diesel. Don't overlook a 435 with a 2 53 Detroit.I pull a 435 and I have had a lot of fun with it. I think I have 60 hp at 2400 maybe a bit more. I have pulled 3200 with 14.9 X 38 But now I run 18.4 X 34 and start at 3500. With the right parts they can have 125 hp. You get to pull first and they are light to haul. Its on you tube John Deere 435 @ Potaka Il. I'm 4500 lb in the video, thats as heavy as I go. Give me a call if you are interested in one. Vic 618 896 2225
 
I bought a junker for 3500 nose was busted. I took it off and made a front. A MT or 40 narrow front will work also. There is a lot of weight to be lost from the engine. I have lost over 150 lb.
 
Right parts and 125HP ? Maybe turbo intercooled with nitrous, water injection and super heavy cam follower springs/ valve springs. with C120's
I should have advanced the cam on my four valve 2-53 with N80's. 60HP net pto at 2400rpm, 70HP at 2800rpm on the dyno.That's with fan, hydraulic pump, alternator.
