    JD 730 PTO clutch shaft oil seal replacement

    I opened the fill port to look inside, it's a bit milk chocolate colored, so must have some water in it. The level wasn't high enough to see it there, but there's a big gear in the way of seeing much of anything. I turned the PTO by hand (not running) to see the oil come up on the gear teeth...

    JD 730 PTO clutch shaft oil seal replacement

    Oil is leaking out the side where the PTO clutch shaft sticks out... looks like it would simply be replaced from the outside, wouldn't have to take the PTO housing apart. Anyone able to confirm? Also, is there an oil seal between the PTO area and the transmission housing? I might have oil...

    Another current question

    The issue is not total power of the system (what the meter outside reads), but power of one specific device, and for that device, it is simply multiplying I*V.

    What type of anvil do I have?

    Same, and my father still has that piece of railroad used as an anvil. We also had a proper anvil that stayed in the barn, but the piece of railroad was portable and stayed in the truck.

    pulling stumps?

    Dead a few years they are probably rotten in the ground, and any attempt to pull them out will just break them apart and won't come out in one piece. It's a lot of work, but grab a spade and dig around them. If they aren't rotten, use an axe to chop the side roots then pull out with a chain...

    Another current question

    Power is always there whenever there is voltage and current. You can always calculate one of the three if any two are known. The skillet in question has only 2 known published numbers, the 15kw and the 240v. This is about power, but only in the first step, for the purpose of using that number...

    Another current question

    That would only be correct if the element is swapped out for one of lower resistance in order to maintain the rated 15kw. Using a 15kw at 240v rated element will pass LESS current if plugged into a 208v source.

    Another current question

    Current can always be calculated if the power and voltage is known. It is typical to list only two out of the three on any piece of equipment, since if you know 2, then you know 3. (power, voltage, amperage)

    Motors running on propane

    I would think engines originally designed specifically to run on propane would have already taken such considerations into account. Maybe gasoline engines converted to LP might have issues?

    Another current question

    Correct! And that is where these other commenters are getting it wrong, thinking the power rating stamped on the skillet must be maintained regardless what voltage is applied. A 15kw skillet will only get that much power IF it is connected to the 240v supply that it's rated. If connected to a...

    Another current question

    AGAIN, this is for a purely resistive circuit. A heating element is just a plain resistor, and power IS calculated by simply multiplying voltage and current. The phase is not what determines how to calculate, it's the load, whether plain resistive, OR if it has a capacitive or inductive...

    Another current question

    Correct! I did a quick research too for electric skillets and found one that ships rated for 240v 3p but can be field converted to 240v 1p, OR they can ship it 208v 3p but field convertible to 208v 1p. In order to keep the wattage rating, the element must be swapped out if using a different...

    Another current question

    Nope, I am correct. My degree is Electronics Engineering Technology. If the only thing changing is the voltage decreasing, then current MUST also decrease. 240v 3-phase is very rare, but might be possible that's what he has. Some erroneously call 240v single phase "three phase" when they're...

    Another current question

    If you reduce voltage, amperage will also go down, (and likewise power goes down). An electric skillet is purely resistive load. If it is rated 15kw with a 240v supply, then that's 62.5 amps of current. Ohms law written for resistance is R=V/I. This means the skillet has a resistance of 3.84...

    Motors running on propane

    My family had a 1947 LP fuel John Deere model 50 that sat for 8 years after a long life working a 90 acre farm. I put a battery in it one day and it cranked right up like it had never been sleeping all that time. The LP fueled 730 I have now also sat for about 5 years or so before I bought it...

    Wide front

    When I was a kid, we had a JD 50 with rollo-matic front end... it had power steering, but not (it leaked so bad we quit putting power steering fluid in it and just dealt with it being hard to steer, but wasn't too bad once rolling). We had a 60 and 730 with wide front end, both had good power...

    Same results with me, sometimes catch a rat, but mostly they will trip them without getting caught.

    Where is the correct place to attach ground battery cable on JD 730?

    Yes, I did notice this when I had the battery box off... new box installed and paint on it would not allow for good grounding contact, so I put it on one of the bolts that holds it to the rockshaft housing lid.
