    Posted: 5 hours 14 minutes ago at 11:37am
What's the heaviest fully mounted rear implement anyone's seen on the back of a CA? I found DennisA (IL)'s videos of his CA with an 8.5' 20 disk and #54 plow, and I know he has plenty of weights added up front.

Of course the closer you can keep the weight to the rear axle, the more you can lift. I would like to set up four #74 row units on a fully mounted toolbar. I am hoping this would be fairly similar to the weight (well, "moment," really, for anyone that remembers physics) of an 8.5' disk, with the disk extending back farther from the rear axle.

Am I wasting my time with the CA idea? My other option would be to set up the row units on a toolbar for a WD/WD-45 which I am confident could handle the weight. I have some weird little fields and am planning on going with 15-20" rows. So, the CA would be more nimble and I plan to cultivate with the CA anyways.

None of my CAs are Snap Coupler so I was planning on tying into the pin hitch setup, similar to how the spring tooth field cultivator is attached. I need to do some measuring... maybe I can come up with something that would work on either a pin hitch WD or CA?

From personal experience I know it's about 800 pounds on a Carry-All. Beyond that the left lift cylinder will blow the end off due to the way the hoses are connected to the hold valve to make the Traction-Booster function. 
  In the Oxnard heavy tillage manual for the CA tractor, it advises plumbing both cylinders to the same port of the hold valve to increase the lift capacity. However that disables the Traction-Booster.
  As you mentioned, The more on the lift, the more front weight is needed.  
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

I put 3 units on the back of mine and have about 100 lbs up front. Never needed more than a few lbs of seed in each hopper. If filling the hopper then 2 would be about all it can handle

Thanks Paul - that is very helpful. I'm not sure what a 74 row unit weighs since they don't list specs like that in the manual I have, but 4 of them full of seed might be pushing it. Maybe I can wrestle one off and get it on a scale, or at least ballpark it by trying to lift one.

The hose/cylinder information is good to know too. I wouldn't need Traction Booster for planting or row cultivating so I might just replumb them.

Well darn. Any chance you can post a picture of your setup? I am curious to see if you have them about as far forward as they can be to the rear wheels or if there could be anything to gain by shifting them forward as much as possible.
