Is There a Specific Measurement from PTO shaft end and 3 Point hook up ?

[MrJimi]

I am building a hydraulic motorized PTO shaft and I need to know if there is a certain inches from the end of PTO shaft to hook up points
and it would be CAT 1 implements
Thanks

Do you mean is there a standard drive shaft length for Cat 1
implements? I have had various cat 1 implements and they have
had different shaft lengths. Indeed my concrete mixer came with
a shaft that was extra long and had to be trimmed down to work
with my tractors. Even allowing for the telescoping range of
lengths.

What are you planning to build?

Hi MrJimi, here is a link to a site that has all kinds of couplings (in case you need something other than pto). Hope it helps. Good luck with whatever project your working on.

Try and picture this, I have a backing plate for my Case 1845 C and I will be attaching a hydraulic PTO motor on it and with a Harbor freight quick connect thing. My question is how far from the end of PTO shaft to hitch mounting is standard or normal? I know it must vary heaps but I would like it to be close to a real tractor mounting arrangement. And , yes, I know that dint make much sense either.
I will post picture or link of my project

Skid Steer Three Point Adaptor

I hope that made more sense

I would think that "standard", whatever that is, would pretty much be the same for most small tractors, measured from the pto shaft to the mounting holes on the lift arms. But, if your going to build/fabricate something like the pic you posted, might think about adding something like this.

Fontaine Fifth Wheel

Then you could mount pto motor to plate that would slide and adjust as in the sliding 5th wheel, and this would be inside the QA arms.

Forgot to add, that with a sliding plate, that would give you some leeway in your shaft length, longer or shorter. But you probably already figgured that out.

I built what you are talking about last fall. On mine there is 18 inches from the pto stub to the centre of the cradles on the lift arms. Works on the blower and tiller just fine. I put 50-60 hours on the skidsteer and blower this winter no problems.

What's more important is whether you will be driving implements from the drawbar and turning/cornering with them. If not, all that's important is that the pto shaft be parallel in all planes with the implements fixed input shaft (the gearbox input, etc.) If the implement is trailered from the drawbar, then you need to arrange the pto shaft such that the center is right over the hitch pin when the shaft train is straight ahead. This insures a constant velocity driveshaft up to the fixed, driven shaft with a double Cardan shaft. If the rotary load is light, it all won't make a heap of difference. If the load is heavy (as in driving a large pto generator or a hay baler) and you turn, the shaft will go into a wobble mode and the driven gearbox will complain. Other than that, just make sure you have enough room between the pto and the implement to safely hook things up. This also demands you use common shaft lengths to the implement ("36 or 48" is common. I have a 24" on my 9' mower and its difficult). They extend quite a bit, but the more they extend, the more compliant and weak they become. If you twist one, you won't be able to collapse it to unhook.

I believe Jimi is driving a skidsteer in which case the implement won't move in relation to the pto shaft as the motor will move with the shaft.

oops, did I forget to mention that I do own an older skidsteer, here is a picture with non-motor 3 point harbor freight hitch on it and I'm sorry about the cell phone picture, it's all I have since my Nikon died

Thanks for pointing that out
Jim
