D17

Welcome,don't know what your plans are but it will handle a 3 bottom plow or a 10 or 12 ft. disc with ease. good luck with your new toy.

Thank you for the info...it is a series 1. I want to bushhog, box blade and later put a front loader on it. Just light stuff oh yeah, tiller also. I am looking forward to learning a lot of stuff here. My philosophy is: "Just treat me like a functional illiterate, that way you won't leave anything out." I probably bought a little big for what I need, but my grandpa used to put me on an allis when I was 6 and let me disc and drag, I still remember that bright orange tractor tearing up that dirt!

It won't know a 6 foot bush hog is there in most conditions. I wish I was good at posting pics cause my 58 has a pair of double acting valves on it. They tapped into the remote circuit and used a return line.

Yes, you certainly can tap into that one circuit and use it to operate a manifold of single and double-acting cylinders, but there's a few things you SHOULD know...

If you tap in downstream of the rear lift control valve, you'll need to have the lift lever held in the 'up' position to get flow.

The rear lift cylinder will raise up.

Next, the output will be high pressure (upwards of 4500-5000psi IIRC) and low volume (2-3gpm or so).

You'll need to provide a return path to reservoir from your valve manifold...

You'll need to be able to 'shut off' your manifold for those circumstances when you want the rear lift cylinder to function normally. 

You could tap into the system upstream of the lift lever and have it 'live' all the time, but I THINK the way the rear lift system works, you might need to use a 'closed center' valving system in order to keep the rear lift working... that, or have an additional valve on your manifold to operate a single-acting cylinder, and pipe that to the rear lift.

But the most important note that comes to mind... if you're planning on running modern implements, using the D17 S1's hydraulic system to run modern implements, you'll have pretty slow operation... and might have some blown-out seals.

This is because modern implements operate using lower pressures (2500psi or so) and substantially higher volumes (8gpm is 'small', 12gpm is moreish normal, and 20gpm is fairly common). 

Running new implements on the old system means your bigger implements (like a modern full-hydraulic loader) will be very slow.

The D17 is an awesome hoss... like you, my first driving experience was raking hay with my grandfather's D17 Series 1.  The deep purr of the AC big 4 is what I hear whenever someone says the word 'Tractor'.  You didn't 'buy too big'.  For being 57hp, it's actually small, very maneuverable, and heavy enough to tackle serious work without stress- you'll like how well it handles, particularly with implements, and as noted, it won't notice a 6' blade swinging off the PTO.

If you're serious about fitting it with a loader, I'd suggest you skip the manifold and plumbing exercise, and look to doing it with a larger-volume manifold, setting up a live hydraulic pump off the front end of the crank, and either adding an external reservoir, return filter, and plumbing, or using the transmission case as your reservoir.  I'm working on a similar setup, as I've got a small backhoe attachment that I'll be setting on and off my Series 1 to do all sorts of digging in my yard.  Many guys have done this, and many aftermarket implements came with similar kits... Keep watching, I'll post pictures of how I do it.
 

Isn't the low volume high pressure system 3500 psi? Dave is right about having to have the lift lever up to have pressure. I'm wondering if the valves someone used are closed center. They tapped in right at the transport valve on mine.

Hey, do people spell your name Lloyd? I ask because most people spell my name Loyd.
