My motto is the customer is always right but when he told me this is what he wanted along with live hydraulics I thought it was real overkill. But after putting it together I think I like it!!!

I think you do really good work and it is shown here. The old original parts along with the new really look good together.

it does look good, and he does excelent work.
all that machine need snow is an OHV engine, and a dual clutch..

I always get a kick out of the pictures of your work you post here.
Get some good ideas too.
On the last picture, the one with the foot and the leg, what is the
thing at the bottom left with the Made In USA sticker on it? It's too
close the the back of the engine to be the pump but looks too
substantial for a filter.

If I'm seeing this right, he has a pulley mounted pump that uses the
fluid in the rear end? Instead of a separate reserve tank?

Very impressive. For a modern small farm, a good hydrualic set-up on an N could be really handy.

I believe that is a flow divider.

I'd rather have PS than lpto.
Very nice work TOH.

i'd go with that tradeoff.
one of my 850 fits that. ps, no lpto works just fine that way. :)
In actuality.. I've only had a use for lpto a very few times..

That is a prority flow divider. The pump is 12 GPM and uses teh tractor sumps as teh hydraulic reservoir. The flow divider splits the pump output into two independent pressure streams. The 1/4" hose is the priority circuit which is set to a fixed 2 GPM flow that goes to the test port for live hydraulics. That is the maximum flow rate the 3pt control valve can exhaust. The 1/2" hose carries the excess flow to the control valve and from there back to the sump via the transmission filler. This one is for a side distributor 8N and the pump is shaft driven off the crankshaft.

I sure like the hydraulic setup and you sure do
nice work, I especially like the rear access ports.
I do have a question though. How do use the lever
for the rear pto lever?

Might be a dumb question, but does the sump really hold enough oil to
run anything that would require that many outlets?
I'm having trouble coming up with an implement that would need it that an
8N could run, other than a back blade with hydro turn and tilt.
Maybe just cabin fever on my part.
Does look like nice work as always!

Same way you always did - lean over, reach down and shift it. Slightly harder to reach it from the seat but you don't need to be a contortionist.

An N is quite capable of running a lot of implements that require a hydraulic system of this sort and Ford provided similar setups for the NAA and 600 sereis tractors. The internal sump capacity is sufficient for this size pump with a couple caveats. First the 12 GPM pump rating is maximum output at 2000 engine RPM The flow rate is proportional to engine speed - e.g 8 GPM @ 1500 RPM, 6 GPM @ 1000 RPM, etc. You also need to consider the duty cycle of the hydraulic loads you are running. For example you wouldn't want to try and run something like a rotary broom tpowered by an 8 GPM hydraulic motor. The motor onteh broom has a nearly 100% fully loaded duty cycle and with that small a reservoir the oil would overheat from the constant high pressures. But you can run something like a loader that actually has higher peak pressure flow requirements but with very intermittent duty/load cycles that give the oil a chance to cool down between cycles.
The valve in the pictures controls two DA cylinders and requires 4 bidirectional couplers. So the coupler count is not as much about volume as it is function. Those are 3/8" couplers good for about 6-8 GPM each which is overkill for the customer's current application which is a front snow plow with power lift and angle. But because he wanted the flexibilty to run a small loader he balked at a smaller pump and 1/4" couplers. In fact he initially wanted four more front couplers to go with the rear ones but I talked him down off that ledge - at least for the time being 
Next N-series hydraulic system on my schedule is a 16 GPM pump for a guy with a loader/backhoe. He will be using his existing 5 gallon external reservoir to up the overall system oil capacity to 10 gallons.
