I'm going to look at a JD 70 Diesel with pony motor. I'm a rookie, is there anything I should look out for? It kinda caught my eye, it doesnt have a 3point though.

I have to agree with the previous posts. Not only they will eat lots of $$$. They need a trailer heavier than a class III hitch will haul. A little 50 with optional PS, live pto etc or a 520/530 is a fine place to start. We have a 70D standard, 70G and a 70LP in progress if other bills would just quit coming in. The 70 three point needs a 800 or 801 hitch to get the upper link or the aftermarket system from Stiener Tractor Parts. The 70D often cracked cylinder heads. Make sure it doesn't leak or is already wearing the 720/730 heads. The timing gears/bearing/shaft often get ratted out and need the updated units from a 720/730. Low reverse is way fast and don't even try high reverse unless way out in the wide open away from anything. 1st reverse is plenty fast for bailing heavy hay etc.
valuable. I am very partial to the 70D my Father purchased in 1955 that I now partly own. I rode and slept on it as a toddler. And later learned to drive. While she has done alot of work (10,000+hrs) on a little fuel. However she is moody and has expensive tastes.

Those 2 cyl. diesels are not a good choice for a rookie to cut your teeth on. I would suggest a gas model as you will have less headaches and expenses. Just my 2.5 cents worth.

Ken...remove the flywheel cover and make sure the flywheel has not been welded to the crankshaft or has any welds on it of any kind. Look in the bottom of the flywheel cover for fine metal dust (sign of loose flywheel). Check the radiator for any signs of soot or oil residue on the bottom of the radiator cap or around the fill neck (sign of leaking head gasket) Check the transmission out in 3rd and 4th gear (plowing gears)for any unusual noises.Check the inside of the exhaust muffler for oily residue (sign of worn rings or bad injectors) Check the pony muffler exhaust down pipe (in front of diesel engine valve cover) for oily residue (sign of worn rings, common problem) Check the crankcase oil on the pony engine and diesel engine for any signs of "white oil" caused by water contamination (bad water pump seals on the pony engine or gasket/crack problems on the main engine)That's a starter list. You will also need to check the power-trol pump and pto clutches depending on what your intended use is for the tractor. 70D's are relatively expensive to work on when compared to gas model 70's. Good luck!

make sure the flywheel is tight. if the tractor is running listen to it an make sure there is no bad knock in it.
also make sure the pony will crank the diesel. you can have just as much in the pony in overhauling then you will the diesel. johndeeregene
