1066 lost hydraulics

Using the 1066 Hydro on the snowblower. Lost PTO, remote hydraulics and 3 point lift all at the same time. What's the problem? It's not the flex plate, because when that goes we lose the brakes, steering and hydro along with everything else.

Unlike the gear drive tractors, the Hydro's use a two piece lower IPTO shaft for the hydraulic pumps. There is a coupler between the two shafts where the center section and the rear frame join together. If that coupler is worn out or broken it would explain the symptoms you are describing.

Any way of checking this without spliting the tractor? Take off something and look in there maybe?

Since the PTO hydraulics are self contained in the PTO unit it is highly unlikely that both the hitch pump and the PTO failed at the same time. However they are driven by the same shaft. If the gear at the front of the PTO drive shafts has failed you will lose steering, brakes, and charge flow to the hydro charge pump. The shaft is turning to drive the front pumps but not turning to drive the hitch pump and PTO.

By removing the upper link bracket above the PTO you can see the PTO drive shaft. You can also see the hitch pump and drive gear. You will most likely have to drain some oil out to see much. The correct oil level is the center of the PTO drive line but with a hydro that level is achieved only with the tractor running. Since the hydro tractor does not have a transmission counter shaft in the center section, by removing the bottom cover you should be able to see some in the too. I don't remember if you can see the actual coupler.

If you remove the cover under the clutch .You can see if the splined shaft is turning, in the back of the clutch with tractor running. If it turns your trouble is farther back. If not then it is in the clutch either the pressure plate hub shot or the splined shaft. Splitting will be the order for that.
You can also pull the plate under the speed trans after draining oil out. Bump starter to see if the gear is turning in bottom front on through shaft for PTO.

What you describe will work for a gear drive but this is a Hydrostatic drive 1066. Completely different drive train from the engine to the rear frame.
