What a marvelous piece of machine that John Deere was and is... I got the chance to ride one of those, pretty much in really bad conditions but still was running strong as hell. Will never forget that ride. Thanks for the video!
You should try using the choke on a cold engine, and get the clutch engaged and Reves up then put big engine on full compression soon after it shows oil pressure than advance the throttle enough to turn on fuel they will start instantly down to about 10 after it starts turn gas off and let donkey motor run out of gas turn off switch
Beautiful tractor and in great shape. I had a 1957 720 John Deer diesel wide front electric start. Loved that tractor. I got well over 4000 hours of seat time on that old girl. Although the pony start may have had an advantage over the electric start in our Iowa winters, I wouldn’t choose the pony over electric start. Just my personal preference Thanks for sharing this gorgeous beauty with the world!
seiously, if you want that pony motor to be good, PUT IT IN THE RUN POSITION WHEN IT STARTS! that way, when the diesel engine starts going, shut the pony motor off and you're good to go.
Who in the HELL was trying to operate this tractor? This joker is straight up going to WRECK that tractor , PERIOD !!!!! Man that idiot kept slamming that pony engine from run to start to run to start and holding it on instead of shutting it down , PERIOD . Joker needs his head crack with a pipe , PERIOD !!!!!
love the 730's. but no one would've ever bought one if this guy had demonstrated how to start it and that flipping those two choke and throttle levers back and forth all the time. that's the worst I've ever seen anybody do. beautiful tractor otherwise.
NICE OLD JONNY>> THE PONY MOTOR IS NOT WORKING PROPERLY ONCE YOU ENGUAGE THE STARTING CLUTCH THE R>P>M> SHOULD INCREASE >>NOT CHOKE DOWN.... THE PONY NEEDS A VET..
You do not know how the use a John Deere Pony Motor the right way. So I"ll tell you. To start Pony turn fuel on to pony motor, then turn on ignition, hold choke to on , keep pony motor throttle at start until pony motor starts, release choke move throttle to run. DO NOT MOVE BACK TO START AS THE MOTOR RUNNS AT VERY HIGH RPM "IT WILL DAMAGE THE ENGINE". Once the big engine is running turn off gas to pony, make sure ignition is off so the magneto ( distributor ) does not burn up. Return pony motor throttle the start after engine is no longer running . Throttle up big engine and put tractor in gear . Away you go .
nice tractor. I spent a lot of time on one of these. the pony motor needs some work though. shouldn't have to do all that messing with the pony motor choke and throttle. I do love a 730 and most any other john deere for that matter.
I tell you all this much, today's gasoline is made mostly for injection, not carburetion. My 70 Diesel was very picky what gas went in it's Pony Motor. I understand the feathering the choke. I had some gas that wouldn't even light when poured on concrete, it was that bad.
Thanks for the video. Your 730 runs really good, and it's good to see someone who actually knows how to handle a pony-start tractor. Most people just start the pony, rev it up, then shut it right back down.
There are a couple of easy "fixes" for a pup engine that runs like a dog - check the fuel level in the little fuel tank, or a dirty fuel screen because it sounds like it's starving for fuel, and also a low battery voltage will make it run like that.
Nice video. But, next time, read the operation manual before you try to operate a strange piece of equipment. obviously not familiar with how to properly operate the pony motor.
Much agreed with pony motor, full choke from the get go pony motor will fire up instantly. I always had throttle in the on fuel position after a min of pony motor running in run less then 3 sec of cranking diesel engine would fire right instantly regardless of weather temp.
To all of you who insist that the pony should be shut down immediately. It’s a good idea to let the little booger run until it’s warm enough to achieve a proper piston ring seal before shutting it down. Continuously cold starting and shutting down an engine before the rings seal against the cylinder walls wears an engine out fast. And so what if he was choking it and giving it some extra air to make sure it wasn’t flooded when it didn’t take off right away. Saying he doesn’t understand how to operate the pony is ridiculous. He’s one of the few people I’ve seen who allowed it to warm up before shutting it down. Although it would have been better to let it warm up before putting it under the load of turning over the diesel. For the expense in rebuilding the pony I certainly don’t mind spending some extra time and gas to warm one up.
Uther MacEanruig The correct procedure is to shut off the gas petcock for the pony motor and it will fuel starve in a few moments, once the diesel engages.
I grew up on one of these and this guy didn’t have a clue what he was doing. And you don’t stop the diesel engine by pulling the decompression lever. There’s a knob you pull out that overrides the stop on the throttle to kill the engine.
