Model D 15 - is there a separate reservoir for the power steering? I have checked all the fluids that I know about and they are all topped off. Between the frame for the front loader and the coating of grease on everything, it is hard for me see what is what. (I bought some degreaser and do plan on getting it all cleaned up.) About half way through mowing with a rotary cutter the steering got really hard, and still is. When I bought the tractor 2.5 years ago, the power steering pump had just been rebuilt, or maybe replaced. Can there be any other explanation for why the 'power' disappeared? The pump? The tractor can still be used, but it's a workout. Thanks!

The older ones may have a separate reservoir hanging off the valve cover, under the hood. A D-15 series 2 has the reservoir in front of radiator, look for the breather/fill/dipstick behind grille, top of pedestal, sticks up about 3-4", round cyl top of a big nut.

All D15 power steering reservoirs are in the front casting regardless of series - same as D14, 17, 19. Fill with ATF to the top of the gear inside.

IF someone put an after market PS on it the reservoir is attached to belt drive pump. IF its OEM as already said, remove grill cover screen and you have a breather plug about 4" H x 1 1/4" diam. fill it so strg gear is covered ( I use an AGCO 821 equiv. in my D15 & D17s.)

Remove grill, unscrew the power steering filler cap(that’s the object in the picture behind the grill) |

Thank you for the replies! I will check out the fluid reservoir and go from there. Hopefully I am just low on fluid. Thanks so far.

Yes, found the reservoir behind the grill. Filled it up to the top of the gears and I once again have power steering. Thank you, thank you, thank you!

You'd better figure out where your oil leak is. Those power steering units go for years and never need oil. Parts are hard to come by and expensive for the power steering pump if you damage it from running low on oil.

Good idea to remove the vented plug and clean it as they do tend to plug off at the top on the sides, it has to vent or you risk pushing fluid out the lower seal in the bolster, especially if overfilled.
Blow it off before removing using the wrench flats so you don't get any debris in the bolster reservoir, lay a clean rag over the threaded hole and clean the snot of the tall plug. I soak em' in gas using a coffee can and enough gas to cover it entirely overnight with the plug upside down. Rinse with clean gas and you may have to use a pick or a piece of wire to clean the top where the vents are; do not remove the top as it is soldered on. I do a final clean with the air hose and break clean making sure it is fully clean and dry before reinstalling with the correct gasket, just a nip on the wrench flats is all it needs. Book states to cover the gear in the bolster 3/8" as I recall but I run em' where the gear is just barely covered and re-check every time I clean the radiator on the tractors used for brush cutting. If it's not been changed out for a while, operate it until good and warm/hot and pull the plug on the bolster leaving it drain overnight and you might be surprised how nasty that fluid gets. In our temps here, the small "fines" that accumulate make plenty of dust brush cutting so I keep an eye on that fluid and blow my radiator out daily; if she's puking out the breather during a 8-10 hour day, the fluid pushed out the vent cap just collects more dust so I just barely cover the steering gear in the bolster and use only 821 equivalent fluid. The D-Series P/S set-up is quite robust, just takes a little maintenance to keep it running smooth.
