I9-425/730 loader REAR counter weight on 3 point

Hi Folks

I'm almost having my I9-425/730 loader ready to go on my 1969 Ford 3400 agricultural tractor.

Question: From the pictures I've attached, what is the amount of weight a 3-point hitch for this tractor can/will take with a loader. I have 320 lb (4 x 80#) wheel weights PER WHEEL in the BACK already. I plan on putting the 5' scraper blade back on, plus I have one of the triangular 3-point receivers too (IF I EVER WANT TO PULL A TRAILER AND I COULD ATTACH THE 300# weight which use to be on the FRONT TO THAT).

Thanks

On my 841 with a loader I used a back blade and suit case weights on it. I have 6 IH suit case weights that are around 85LBS each plus a 150lbs wheel weight one the center link part of it. The back blade is not a light duty one either so it is also pretty heavy. Plus I have fluid in one tire. I need to put fluid in the other one but just having gotten around to it yet

All the weight you can add... I have not got around to doing the 55 gal drum full of concrete on the 3 point yet but need to... The Moe the better your machine will thank you for it...

Thanks all.

Mostly wondering if there's a MAX 3-point weight RECOMMENDED BY FORD

Can't trust everything on the tractordata dot com site but they show the value as 1700 lbs at the end of a 24" lift arm. BUT !!!! NOTE !!! Your lift arms are probably longer than 24", and your weight will likely be hung aft of the arms, so you'll have to do some ciphering. Example: if lift arms are 30" and all the weight is centered right on top of those pins, then you're looking at 1350-60ish lbs max. Hang the weight aft of the pins and the max weight lifted is reduced even more - for your calculations, you should probably figure the "arm" length as being to the center of the weights, not to the pins.

Probably want to put some stabilizer bars on the lift arms to keep the weight from banging back & forth.

In the original 3000 owner's manual it states:
[i:654c4848f0]"In the case of mounted equipment, the amount of weight should be decreased by the weight of the equipment so that the approximate rear axle weight does not exceed 5000 lbs."[/i:654c4848f0]
This includes wheel weights and or liquid ballast.
In other words you can pretty much hang everything you own off the back and be ok.
Generally the 19-425 # tells more about the mounting kit and which tractor that loader was mounted on.
If you refer to it as a 730 we will know what you are talking about.

good post...right from the book.
With 3-point mounted counterweights, in most cases the design engineers have already done the figure'n for you.
Add weight to your counterweight til the relief squeals at ya when you try to lift it. take some weight back off. That's about right. Lift it, then lower it onto check chains to give your hydraulics a break...and happy loadering.

little related side story....I made a counterweight for a modern 33hp loader tractor...dunno, 700 lbs or so. I always worried it was too much for the little fella. Traded it in on a new one to beat the emissions hammer...[i:6e94cb92ae]same model[/i:6e94cb92ae]...but with a backhoe.
wow that backhoe looks heavy and is mounted waaay back there. Guess my little counterweight was ok after all!

Ultradog, yes the rear axle and wheels can take pretty much all the weight he can possibly add to the tractor, but the 3 point lift system has its own limitations on how much weight you can lift with it, so the original question on how much weight he can add to the 3 point arms has a different answer, unless he's going to hang the weight on the 3 point in the lowered position and never raise the arms.

thanks
