Looking for weight limit of hydraulic lift cylinder

[semper5 43]

I am wondering about the weight limit for the hydraulic lift cylinder on my C145. I am welding up a rake which will attach to the plow so i can go 'rough up' areas that are overgrown with weed, or if I want to scratch the surface of the ground prior to leveling and so on. 

My rake will consist of flat stock, 42" wide, it's 3/8" thick. Along the bottom will be welded bar stock, 1/2" x 1/2", every 3 inches or so. Total weight of this will add about 26 lbs to the blade. Would this be ok for the lift cylinder? I think it will be, but I'm still wondering about the total limit for the cylinder.

Thanks for answering!

It will be fine. I don't know the limit of those cylinders but you won't hurt anything by pushing them to their limit. There is a pressure relief in the spool valve so if the cylinder reaches it's capacity, the excess pressure will bypass.
I bet it can handle much more than 26 extra lbs

Here's an example, I recently sold an Electro 12, it had the cylinder to lower n raise the deck and rear lift. And if you wasn't paying attention whenever you raised the deck, it would with bend the Linkage real bad or snap it like a twig... And it's a little cylinder...hydrolic pressure can handle a ton (probably literally) lol,with no problems.

Oddly enough Johnny Bucket designed their product with an electric actuator because they felt the Wheel Horse hydraulic cylinder didn't have enough capacity. It may have to do with the design. Did earlier tractors have different pumps/cylinders?

Nope they have been the same cylinder for all the hydraulic lift years I think.

The lift cylinder itself, if the system is functioning properly at 700psi, the cylinder can pull 1100lbs of force (which is up i think, 1237lb push for downforce), then you have to figure in mechanical advantage/disadvantage of whatever lift linkages are in use.

Johnny Bucket just wants to sell electric lifts. They would have to change there design to use the WH hydraulic lift is the other reason.

Well and the other thing is they would have used the cable lift, not directly hydraulic. The cable might be the weak link. Also, it would not have been able to provide rear down force, which is a big selling point and I would venture to guess that is the main reason to not use the stock hydraulic. (and they most likely would not want to sell a system that has to tap into factory hydraulic as they dont all have it and its a liability)

Actually JB doesn't sell a Wheel Horse-model sleeve hitch. I have the Universal model on my 523Dxi because the frame goes all the way to the rear of the tractor. The Wheel Horse design is very different than most other manufacturers's tractors. My comment about lift capacity was concerning the JB Bucket.

Aha, didnt catch that. I could see where that wouldnt have enough umph for a full bucket. The attachment arm puts the lift at a mechanical disadvantage in exchange for throw, so by the time you got enough throw to lift a bucket, you would have very little power left.

I never posted a pic of my finished surface-scratcher, so here it is. Has come in so very handy!

If you have the lift BAR and not a chain lift it should pick the front wheels off the ground. That down pressure is a must for grading. I must say I like what you have done, good luck!
