Allis D17 hydo. factory options??

Was there a factory option for D17's to have remotes and traction boost control over the right axel? Or is that after market?

Was this all series IV's or just late one that had this location of controls?

Look like this:

How about a series 4 with snap coupler? Were the controls on right hand side or like a series 3?

The new modern "live" 2,000 psi hydraulic system of the series IV D-17 is why that tractor is so valuable, especially if it has the factory optional Cat#2 3-point hitch. Summer/Fall of 1964 was an exciting time for Allis dealerships and their customers. The D-19 was replaced with a truly revolutionary looking and first of its kind operator platform tractor, the mighty One-Ninety. It too had this new "live" 2,000 psi very modern hydraulic system at the same time the D-17 IV was introduced, as the whole hydraulic valve stack was identical between the two tractors. John Deere had been trying to convince everyone that their new "closed-center" hydraulic system (3010/4010) was the future of tractor hydraulics, but this new Allis system was better in many ways. Interestingly enough, Massey basically copied Deere's closed center system (model 1100) but no one else in the industry ever did.

That’s interesting! Appears to be a “series 2” in that advertisement, was there a date on it?

I think this even being offered as an option in 1960, shows that there was a NEED for hydraulics more modern than what the 1957 models were designed with. It took them until Summer/Fall of 1964 to finally get it right and standard equipment on the series IV..

would be kind of neat to fird one of those set ups

A little clarification is needed here after the last two posts. There was NO HYDRAULIC SYSTEM OPTION on the D-17 series 4 model. ALL series 4 D-17's had hydraulic levers to the right of the seat built into a console that included a Lift/Lower hitch lever, one or two remote (2-way) levers, a Traction Booster control lever and Position control lever. These two levers were side by side and at the rear of the console. This system was "LIVE" and used oil from the torque tube. It worked whenever the engine ran, foot clutch up or down. The two color pictures above are a series 4 tractor. *** The one black and white picture was an OPTIONAL system for PRE-series 4 models and included an oil tank, as it was a completely separate hydraulic system. It was powered by the belt pulley drive and could be shifted in and out of gear and went dead when you pushed in the foot clutch. There was NOT a Traction Booster lever included. There was NOT a position control lever either. The Traction Booster lever system was still on the steering wheel column and operated from the internal belly pump. A Position control lever never existed on an older D-17 tractor.

That was a valve option that utilized the standard hydraulic pump inside the belly. Located on the left side so you could/had to use the Power Director lever. That valve was able to be dialed down to 1500 psi for brand X 2-way cylinders.

i have been looking at a parts tractor series i d17d has all of the mounting bracket and two levers and valve on the left side of the tractor, it all looks the same only the oppisite side just remote vavles not lift or traction booster

Double check the serial number to confirm it really is a series 4 - don't go by the decals. Have seen several older models get new series 4 decals after a cheap repaint. All Series 4s had hydraulic controls on the RIGHT side of the seat. The tool box goes on the left side.

Doc can you explain the procedure for "dialing down" the remote bank on the LH side of Series III and older to get to 1500 psi? Thanks.

The optional valve stack to the left of the seat could be adjusted for 3700 psi (for A-C hyd cylinders) or 1500 psi (for all brand "X" cylinders). It allowed the Allis tractor high pressure hydraulic system to operate other "low" pressure cylinders without damaging them. There was a knob you turned fully Cwise or CCW to get whichever pressure you desired. It had to be set for 3700 psi to operate the lift arms or their lifting capacity was reduced.

i will probley have to give 400 for all the left side stuff or 1600 for the whole tractor its deisel and i need everything from the deck up on the engine , just got a series 4 gasser from the wrecking yard , just cannot believe all the differances i have only been around series 1 d17s i did not even know that they made them in gas until i got on this forum
