0:46 get out of the way dude , there's people trying to watch tractor motors start other tractor motors . Would have liked to see this thing drive and plow or something , but just watching it start is it's own kind of fun too !
@TheRebelman95 That would be a pony motor. You need some pretty bitching torque to get that flywheel spinning to start the tractor. Most of the more powerful and....umm...(newer) antique tractors have them.
@82hellbilly actually the R did have hand start as an option on the pony it is a rope pull. My R has it. Available only on 49-50 models. Then the 80 &70& early 720/820 had only electric start pony. Late 720 820&730/830 all had direct electric as an option. 24 volt center ground system.
Are all gear linkages and clutches and throttle, etc. connected too so 1 operator can run this thing? If so, why not start one with the pony and pull start the other? The one with the pony needs to be the one providing hyd. for steering to be safe. I've operated and maintained these pony engines on a 70D. Fun, but a pain! Pony could use a governor a few hundred revs lower and still turn the big diesel over if you know what you're doing. NICE TRACTOR!
I am not sure I made this clear, this is not my tractor, I saw it at a tractor show. But, yes, 1 operator runs everything from the rear operator platform...don't remember there even being a seat at the front operator station. Probably start the way they do to minimize strain on the geartrain, if I had to guess. I agree tho, nice tractor!
6mbtttr9 , the pony engine on the R is entirely different than all the others. It has a trouble-free magneto ignition, rather than the very troublesome coil ignition the v-4 pony's had. It has only 2 cylinders & a very reliable very simple mixing valve type carburetor. this was the only way these came, there was NOT another option, i.e. electric, until the 820 came out & the 720. even then it was a poor substitute- the huge bore & 8" stroke made electric start very difficult in cold weather.
This is one strange tractor setup. What is the readoning behind siamese ing these two tractors? Abd is he starting a smaller engine to crank the larger main engine in each tractor. It is a great video!
back in the 50's the R was the biggest John Deere you could get. If you had a big spread and needed a bigger tractor you had to get creative. This was a trend at that time to allow more land to be worked by less people.
Yes, that is how the R started, there is a 28 cubic inch 2 cylinder pony engine on the top of the big diesel. you start it and let it warm up for a bit then pull the handle and let it crank the diesel over to start. The other option was to have a 24 volt glow plug system.
@82Hellbilly By electric start, do you mean direct start or electric to wind over the pony? The R, 80, 820, and 830 are still pony motor start, direct start electic start came to the big tractors sometimne after that. They all had electric to start the pony.
@DOffio I mean direct electric. And your wrong there. The 830 was available with direct electric. I have seen enough to know you don`t start the pony by hand. I own a 730 with a pony.
stinkingdog101 , at this time there were many many of these tandem tractor setups, even companies selling the kits & installing them. every brand of tractor was done, it was the only option for awhile to get more power, & a much cheaper option a few years later when these became small tractors. If you search there are three 830 jd's linked together, each very similar to the R only newer & more power, with a cab added. 225 hp total. they are incredible to watch in the field.
got to love those pony motors :P

@freakyboie19699 This is for doubling the horsepower available to pull larger equipment. Brilliant idea back in the day.

the 1st 4wd tractor
icewolf1100 4 weeks ago
@icewolf1100 Actually this is by no means the first (the model R was first made in 1949) a short list of some notable 4wd tractors that are older,
1930 Massey Harris GP most popular of the early 4wd tractors.
1922 Rogers had a setup most like our modern 4wd tractors.
1921 Samson iron horse oldest 4wd tractor I have found.

It would be simpler to start one engine then use that tractor to pull ( or indeed push ) start the other one

Deere did not want to put the bulky 24 volt systems on their first diesel, so they went with the pony motor design.
