D7-17a tilt blade with No hyraulic unit?

here it is I found it on rock and dirt

Back in the day there was a #44 hydraulic control unit that could be mounted on the front of the 17a behind the grill. They were normally a two valve and those are the control reach rods in the guard going down the LH side.
Looks like it has been set up for one valve and I can see the empty hole in the guide block where the other one went.
The system was originally part of the Gyro dozer option for the D7. Pretty rare stuff.

The more I stared at it I got to wondering if that was the case

so I am guessing there is no two valve option for a No.46 so in turn there is no real good way to have a hydraulic tilt blade on my machine then without a pto pump which i would prefer not to do because I would like to find a cable unit and a pull scraper someday.........

No option on the #46, not factory anyway.
There is still the possibility of front driving a pump but it would be a custom built affair.

There was even an electric drive screw tilt cylinder in the day, what a morfidite that was.

I wonder if this is a later blade from a D7E, the D7E, D8H and D9G machines were available with cable control and the hydraulic tilt driven from the transmission pump, using the tranny as a reservoir? The pump location here is a mystery though.

I remember some years back, going nuts trying to identify this system when I think it was Ag Mike that actually found one. Problem was it is listed in the Parts Manual as a rear mount....no way.

Farmer matt,

The tilting blade really makes a production machine. I altered my 2U and used the generator drive at the waterpump to power the system. This way it is gear driven with no belts to fool with. The 2U never had the electric start on the pony and as long as the mag is working, it always starts fine with the crank. I can tilt while pushing with no problem. firpitch
