You might consider carrying a couple of empty gas cans to drain the old gas into.

Also drain any old gas from the carburetor.

Don't clean the sediment bowl because it may not reseal and then you have created a gas leak; don't ask me how I know.

As Hugh McKinney recommended below, make sure to check the oil at the oil level test cock.

If necessary remove the crankcase oil filler cap and add oil through the crankcase oil filler opening located near the distributor.

Add oil until it drips from the oil level test cock.

Make sure to check the oil in the air cleaner cup; clean the cup and add oil if necessary.

I have found air cleaner cups completely empty and dry, filled with water, and filled with dead bugs.

Open the oil level test cock to check the oil in the Powr-Trol.

If necessary remove the Powr-Trol filler plug and add oil until it drips from the oil level test cock.

Check the oil level in the power shaft clutch housing (PTO) by removing either of the two filler plugs.

If necessary fill with 10W oil to the bottom of the threads.

The power shaft shift lever must be engaged to the left for the PTO to operate.

Disengage the tractor's clutch lever and engage if necessary.

To operate the "live" PTO, pull up on the power shaft clutch lever located on the bottom right side of the battery box.

Check the position of the Powr-Trol pump shift lever as Hugh McKinney recommended below.

The photo below shows the Powr-Trol pump shift lever disengaged in the OFF position.

 photo c6065010-d664-446f-ae96-018db3c4bdc1.jpg

If you test the operation of the rockshaft hydraulics, the Powr-Trol Pump Shift Lever must be in the ON position before the tractor is started.

 photo bdb38510-819b-44f6-bccb-16da8ce1c7d8.jpg

Once the tractor is started and running, the Powr-Trol pump shift lever can not be engaged.

Be sure to check the water in the radiator.

Hope this helps.

"Either of the two plugs"?? The forward plug is for the transmission/differential grease. Power troll oil goes only in the rear plug.
This goes with the photo for power shaft clutch info.

Darn it. I meant power shaft clutch oil not power troll oil.

You"re very welcome.

Figured a lot of photos would help since you said you"re not familiar with old JD tractors.

James, just to update you on the 70, the lady selling it is very flighty and hard to deal with. I went there prepared to work for 1-2 hrs to try to start the tractor, and she insisted she didn't have time for that. I determined, based on what Hugh told me, that this tractor doesn't have live PTO. That's something I really need, so I think I'll keep looking. The same lady also has a gas 720, but it's really fine and I don't think I can afford it. I hate to make an insult offer. The 720 would have live PTO, yes?
