Running a milking machine with a Cub

Postby WaMoo » Thu Dec 19, 2019 3:57 pm

I’ve often heard the purpose of the 1/8” NPT plug on the intake manifold was to run a milking machine. I’ve even seen it mentioned on this board before.

So, I decided to see if the Cub could pull the necessary vacuum. I believe the recommended vacuum for a Surge belly milker is 12.5” of mercury. My milker of choice, NuPulse, recommends 12”.

With the rig off my vacuum pump installed on my Cub, at full throttle I could pull 14” of mercury with the vacuum regulator all the way closed. (After the engine warmed up some, the needle actually hit 15”)

So, in theory, I think with a Cub you could run one milker, but you’d have to be careful with your vacuum as there is no reserve.

Just thought I’d share the results of my experiment! Not sure I’d try it on my cows unless it was an emergency, but hey, it would beat milking by hand!

Happy Holidays!

Always wondered what that valve on my Cubs intake was for. If I was ever to guess it wouldn’t have been that. Cool!

We ran ours once with a C Farmall. Works better at idle, more vacuum.

The question is how much air flow can you get and still maintain 12" of vacuum. I have no idea how much air flow you get per milker or even how you would measure it other than to just try it out.

That is pretty darn cool. How many cows are you milking? And what kind of cows? Nice to know you have a back up plan!

when I first started making home made wine I ran a vacuum off the manifold to a 5 gallon carboy. I then went from carboy one to a second carboy then to a wine filter. I pulled the wine thru the filter to the second carboy.I used the first carboy as a vacuum reservoir. it worked very well

...so in theory and in practice, you'll be able to chug your Cub about the pasture, idle up next to a cow, pop the gear shift into neutral, and say to her "Nellie, Your next!," get off the still humming Cub, clip on the milkers and go to it. Just as I thought...who needs a milking barn with they've got a Cub--you'll just need a Cub barn. Trouble is, every time the cows hear the Cub starting up they will think it is milking time, even if it isn't and so they'll be trotting along beside you as you sicklebar a field, tow this or that. But, please do put the Cub Milker to work. Would love to see a photo of Cub-to-Cow, the Farmall Symbol of "Aren't you lovin' it?" (PS: Great job!)

I think for a normal sized cow you’d need an H.
For a Cub and for starters you could get one like this... https://newjersey.craigslist.org/grd/d/ ... 84962.html

You may want to fab up a bar / hitching post across the front of the Cub to keep Elsie from wandering while she’s being milked.

Stacy,
Nice work - where's the video? I hope it's on your youtube channel. I haven't check into your channel lately, so I might have missed it if you made one.

The old man who owned the farm I grew up on had the vacuum fittings on his Allis Chalmers WD 45's as we had frequent power outages. He also had an air hose that would go in place of a Spark Plug for airing up tires on the spreader. TJ

I’m not sure the Washington State Department of Agriculture would look to kindly to me milking out in a field! It would be a sight I would like to see though! Maybe I’ll stage it someday!

Surprisingly, my cows love the sound of machinery. They get all excited any time a tractor starts up!
