Up until recently, I have purchased non-running GT's (which, for the most part, stay in some form of non-running state). I bought a JD 318 off of Craigslist (with front plow and 3 point hitch). Now I am having doubts about the purchase and would like to find the answers to the following questions (or reassurance) as I am unfamiliar with hydro, JD, and Onan engines (I know...I know....why did I buy it then... just so you know, you sound like my wife :)). The serial # is 324835.

  1. Would you advise using Mobil 1 10W30 with the Onan engine?
  2. Do I need JD hydro fluid or is there something better or the same quality for a lower price?
  3. Do these tractors usually slow down, slightly, going up hill or is this a concern about the hydro?
  4. When the PTO, for the mower is on, should the PTO light on the dash light up? If the PTO light lights up, is that a bad thing? The belt was in poor shape when I bought the tractor and I replaced it, can't really say for sure if I have seen the light since then.
  5. The previous owner installed an electrical fuel pump, is this common? 
  6. I usually run the throttle 3/4 of the way open. After a while, 30 minutes or so, I notice the throttle has moved back to half throttle, it moving so slow I don't even notice. Is this common or is there a fix.
  7. What is the most important thing to check on this tractor (probably should have asked prior to the purchase)?
  8. What is the most important thing to maintain on this tractor going forward?
  9. Someone tell my wife I got a great deal, it doesn't really matter what I paid, just tell her that any way.  :)

Thanks!

1. Cant help you with the oil recommendation.

2. JD Lo-Vis Hydro oil if the fluid is clear...........Auto Tranny fluid if it is red

3. Check and make sure the hydro is full of fluid.......should be able to see the hydro fluid in the sight glass on the right side of the hydro in the rear.

4. Yes the PTO light should be on when the PTO is engaged.

5.  Electrical fuel pump is not an issue as long as the PSI is correct for the engine.........2-3 psi if I remember correctly

6.  I think there is a nut/bolt combo on the back of the throttle just behind the dash that can be tightened to put more tension on it.

7&8 are subjective............

The manual on the 318's I have worked on state you can use JD Hyd Fluid or ATF Type F but do not mix the two! The Jd fluid is brown in color and of course the ATF is red.  I think you are better off staying with the JD fluid it may be a bit more expensive but..  If you change fluid make sure you change out the filter as well.

 

As Robert said you should be able to tighten up the throttle to stop the creeping.

 

Oh and Welcome to GTtalk!

no, no synthetic in an air cooled engine... better off with  regular 30W or 10W30. especially if this is like I think it is, an engine w/o an oil filter...

10W30 IS the recommended oil, but I've used Rotella 15W40 for years in all my engines without any issues at all.  Not to start an "oil war", but it works fine for me.  One oil for ALL my tractors, both large farm V-8's and my smallest air cooled.

We are like Daniel and run Rotella 15W40 in every piece of equipment we have. From a 1/2 hp Briggs up to out 350 Big Cam Cummins. Only oil issue we ever had was when one of our employees didn't check the oil and ran the engine out of oil!!

I'm swapping over to the Rotella! If it works on the big stuff, these smaller tractors should be fine!
