i am installing a davis 101 loader on my mh 50 .i am trying to find a connector for the crank shaft to drive the pump shaft . i am thinking about also trying to hooking it to the pto. dont know if 540 rpm will run the pump ? thanks for any help d in ut
 
I used a front pump on the PTO like that for the same reason. It had a large [ about 10" or 12" sprocket ] on the PTO with a chain to another small sprocket on the pump. I had it done at a shop so i don't know what ratio they had to come up with to make it work. It was used for a few years but after a while the chain and sprockets wore out and had to be lubed ofter. So i bought a "Prince" PTO pump and that's what is on it now. They work well until you need to use the PTO for something else. I fixed mine with easy off hose connections , about 5 min removal time . I then just raise the bucket up about 2 feet of the ground and remove the pump so i can hook up the "Brush hog" .

Correction , i raise the front of the loader up before i remove the pump. Then i just don't touch the control levers on the loader so it will stay up.

I've been gathering parts in order to install a ford
loader onto my 50 along with power steering parts
from a 65 and a drive gear from a 2135 which needed
drilling and a key way cut.My fel has the front pump
with the stinger connecting to front of crank while
my 65 has the pto pump.I prefer the front pump over
the pto.I'm sure you can find front parts online.
 
The front pivot pins on those 50's are solid, and use a thrust plate with 2 bolts to keep the axle from moving back, and the pivot pin is part of the front axle. The 65 is the same way, my 2135 industrial has a removable pin in the front axle that is hollow if the pump up front. On the 50, and 65 the front steering I believe may also be in the way. I believe a front mount pump may not be possible on them so you may want to study the front of your tractor, and the front axle pivot may not be inline with the center of the crankshaft. The pump will probably need to be mounted offset from the pto shaft with something like a chain drive with something close to a 4 to 1 gear ratio. The pump needs to spin around 2000 rpms, the loader would work pretty slow at 540 rpms.
 
I added loader to a mf65, but couldnt add to the front because
of steering in the front wouldnt allow to fully turn left or right,
so i added pto pump.

You may want to have a cylinder lock made that can be retained to the cylinder rod to keep the loader arms up, it can be made to any length to keep the loader where you want it should you bump the lever.
 

Thanks for the concern and the link. It's only 2 feet off of the ground and for only 3 hours 3 times a year . I never get under a FEL any time , pump on or off. The worst part that can happen in my situation is to bump the controls letting the bucket hit the ground then having to walk back to the shop and get the pump to instal and lift the bucket back up. Not new at this , been running stuff like it for about 60 years, i know the dangers. :) JIM
 
4on-the-floor, I was suggesting a cylinder lock of some sort (or if your tractor has strong grill guard you possibly could use it to chain the loader up) just as a time, trouble saving measure so you don't have to put the pto pump back on when your out bush hogging.
 

Yes i know what you were suggesting. It takes me less than 10 minutes to disconnect the back blade , about 5 minutes to remove the pump and about 15 minutes or less to hook up to the bush hog . Pump is removed so i can connect the drive shaft of the bush hog to to PTO. Pump has hose disconnects that won't leak after removal and only loose about 1/2 cup of hydro flood each time i remove the pump. The loader stays at what ever height i want to leave it 6" or 24" up off of the ground . It does not leak down as i use the bush hog weed cutting. I don't need it supported any higher. I never drive around with the loader scoop way up in the air above my tractor accept when i am loading in to a truck bed.
That's a good way to flip a tractor over on it's side. So a chain lock is no help i don't plan to get down on my belly and roll under the FEL scoop when it's 6" to 24" off of the ground. Sorry you misunderstood what i meant . It's safe , now way to get under it buy accident and the heavy bucket scoop is low close to the ground. After weed cutting another 30 minutes or less and it's back together to use the FEL. JIM
 
I was talking about a lock of some sort that would hold it at 6" to 24" off the ground so you don't have to stop in the middle of the job to R & R the pto pump. The link I put in the one post wasn't the exact example I was looking for.
 

I know you meant well but i don't have to stop in the middle of the job as long as i don't pull on one of the control levers . It's only a 2 or three hour job of cutting weeds about three times a year. So there's no need to kill time locking it up when all i need to do is not touch the control levers.
