Ford 3910 with no pto

Good morning.

I have a 3910 that was formerly attached to a Brouwer 1570
sod harvester. We are no longer in the sod business, so I
removed the harvester from the tractor, with intentions of
using the 3910 for a spray rig. Low and behold, there is no pto
shaft on the tractor, which I should have guessed as there is
no pto shifter either.

There is a plate bolted on, covering where the pto shaft
should be.

Is it going to be possible to add a pto to my tractor? Or do I
need to find a new rear end for it that already has a pto?
 
Does it have a 3 point lift? If so, which type of pump does it have for the lift, one mounted on the left side of the engine near the flywheel or one mounted in the right side of the rear axle center housing? The 3910 would have come with the pump in the center housing if it came from the factory with a PTO because it would have had independent PTO that is controlled via hydraulics that is powered by the rear section of the center housing mounted pump. If it came from the factory with a 3 point lift but without a PTO then it might have had an engine mounted pump so you would have to install a center housing mounted pump in order to get a working PTO.
 
The 3910 has three point lift from factory. Left of flywheel
pump.

If I am understanding correctly, I?ll need the center mounted
pump, in order to install a pto. With that installed, would I be
able to also put in some hydraulic remotes on the center
mounted pump?

Do you have a part number for the center pump?
 
Remote valves mount in place of the 3x5 plate on the top cover, regardless of which type of pump it has.

Since yours has the engine mounted pump and came from the factory with no PTO, then I'm not sure if it even has the dual input shaft on the transmission to be able to drive a center housing mounted pump.

What transmission does it have, the regular non-synchro or the synchronized trans? If you don't know for sure, post the model number, which is on the sticker on the under side of the right side hood panel and also stamped into the flat spot on the bell housing near the starter.

That's interesting...

Model ca514c breakdown:

CA5 at the beginning - at least according to my documentation would be a 3930, not a 3910.

The 1 says it has a diesel engine.

The 4 says that it had independent PTO when it left the factory.

The C at the end says that it has a non-synchro 8 speed transmission.

Unit 3h16b says that it left the assembly line on August 16 of 1993 if it is a 3930. If my references are incorrect and CA5 is a 3910 then it would be 1983 instead of 1993.

It almost seems like the hood that the sticker is on might be from a different tractor if yours is truly a 3910.

I'm not familiar with the differences between the two models other than the 3930 was made after the 3910. Hopefully someone else knows what to check for to be certain that it is one or the other. Does it have a white grill like this:

or a black grill like this:

It is definitely the 3930.

You say it was supposed to have a pto from the factory, it must have been removed by whoever put on the sod harvester. The outside stickers say Brouwer 1560 as the sod harvester manufacturer. Where do I go from here to add the pto back onit?
 

Biggest difference between the 3910 and 3930 is the front axle and steering.
3910 still used the sweep back axle and dual cylinder power steering of like the 3000, 3600 before it.
3930 has the same style heavy straight front axle used on the 4000, 4600, 4610, 4630 but has shorter spindle drops, it also has hydrostatic steering like the 4630.

Does the tractor still have the pto control lever on the left side, if so maybe they just pulled the rear shaft out and put a cover over the hole.

If the pto control handle is missing I'd drain the rear axle, remove the left foot board and then remove the inspection cover, look or feel for the lower output shaft coming out of the bottom of the trans. If there's no shaft sticking out and it has a plug in that location there's no shaft or gears inside the trans to drive a pto unit.
If that's the case you'd be better off finding a used trans with all of the components already there than to purchase the parts to upgrade your's.

Look for the numbers on the flat pad behind the starter to see if they match the ones on the hood.
 
So... if the tractor has a 3-point hitch... it has some type of internal pump. It should also have the drive shaft through the transmission since that is required to drive the internal pump on a 30 series tractor. If there is no PTO control valve on the left side of the rear axle housing then you're probably going to have to scrounge some parts. If the valve is there and simply missing the handle you may luck out... In short, if it doesn't have a PTO clutch, you'll need to split the tractor at the axle housing, add the parts and hook up the hydraulic supply and install an output shaft. You'll be into some dollars. The easy way, and perhaps the economical way.. is just get a rear axle with a PTO.

Best thing is if he can post some pictures of the tractor, front right side angled shot of the whole tractor and a close up of the right side showing the whole area around the right foot rest.
 
OK, that front axle and steering setup is definitely not from a 3910. It looks like a 3930 front axle and grill, which matches the model number you posted. It also looks like it has both the engine mounted pump and the center house mounted pump with the flow control valve above it. So it has everything it needs hydraulics-wise for the independent PTO, which also matches the model number. It depends on what parts were removed when they removed the PTO as to what parts you will need to add a PTO back to it. Only way to find that out is to look at the inside. I would start by pulling the round plate on the left side where the PTO handle would normally be and see what's inside there.
 

That tractor has the optional dual hydraulic pumps, since it has the rear pump all of the components to run the pto are in the transmission.
You just need all of the rest of the components that go in the rear axle.

I may have part of what you need, I scraped out a 94 3930 a couple years ago, the pto components are still in the axle housing.
This tractor had a shuttle shift trans that uses a different pto output shaft, don't know if I have a extra pto shaft or not.

Check around some salvage yards to see if they have a complete pto package they'll sell you.
 
that tractor has the dual pump setup for load sensing hydraulics... so if you want to add a CCLS spool stack that will be easy. Given the appearance of the left side with the blank plugs in place of the PTO control... I'd say you have no PTO components from the factory. You'll need the clutch/drum, control valve, brake components and output shaft and retainer.

I got time to pull things apart and drop the oil. The only parts
still on the tractor are the output shaft on back of transmission,
no clutch or anything is there. Does anyone have parts or do I
need to find a rear end?
