  • 860 sprung a leak
  • The 860 has been out of commission due to electrical issues since fall, but I finally got around to installing a new starter solenoid from Just8Ns yesterday. I checked fuel, air, & oil then she fired right up. About halfway down the drive I looked down to see the temp gauge pegged out.

    After getting back to the barn I found the radiator was just about dry. No idea where the water went. Hoses were all good, no leaking around the tubes or tank. I went ahead & filled the radiator & started her up again. Temp fell back into green right away & stayed there until I got through with my driveway grading.

    When I stepped off the tractor I spotted this behind the starter case....

    I'm not certain, but I seem to recall pulling the original freeze plugs out to flush out sand I discovered behind the original temp bulb. First time I've seen one rot out like that.

  • Geez Jeff at first glance I thought it was a sloppy brazing job or you had discovered how to make gold nuggets......anyway looks like a real good flush is in order.

  • LOL, I flushed quite a bit of sand out of the block when I restored it. I guess that replacement plug was a bad one.

    BTW, it looks like a split is in the near future for the 860. I can't get the pto clutch to disengage anymore. I split it to repair the pto input shaft back then too, & I checked the clearances on the clutches while in there, but I must have missed something.

  • After you get the clutch unstuck one way or another, make sure you keep your clutch pedal blocked down from preventing it from getting stuck again.

  • I'm thinking some of you fellows in the south don't use antifreeze in your tractors.
    If you are running straight water that might be the cause.
    I'm thinking the old soft plugs might have been stamped out of a better quality, more rust resistant steel. Nowdays they may not be.
    If you are running straight water consider using a 50/50 blend of AF. AF does have rust inhibitors in it.
    Just a thought.

  • The 860 has had 50/50 mix in it since I've owned it. We don't get too many hard freezes, but enough to use antifreeze in all water-cooled outdoor equipment.

    I actually knocked both plugs out of it when I was doing the restore on the tractor. I flushed quite a bit of sand out of it. I discovered the old temp bulb had sand packed in behind it.

    I guess that new freeze plug was from a bad batch.

  • In my case I suspect most of the damage was done before I bought the tractor. It came from western Kentucky.

    I would think they would use antifreeze down there but don't know.

    With a current temperature of 13 degrees we definitely do use AF here.

  • I live less than 100 miles south of Western Ky and it is not uncommon here to get zero and teen weather. The coldest on record here was -29 F years ago. I remember -15. We all use antifreeze.

  • Been quite some time but I would guess I bought the tractor within 30 miles of Cairo, Illinois. My brother and I made the trip down and back from Mt. Pleasant, Iowa in one day pulling a trailer.

  • I live 100 miles south of Cairo. A bit of trivia: at one time cotton was raised in the Southern Il area but the growing season was just a little too short and was continued in the 40"s No cotton in Western KY, but tobacco, but cotton picks up again in Western TN.

  • I had one rot on my 860. Makes them easy to remove. Just shove a punch through the weak point and pry it out.

  • An 860 will run better without a freezeplug than most Ns with them, LOL.
