Hydraulic oil change on a New Holland T1510 HST

[Heeb]

Does anyone know how many drain plugs for changing hydraulic oil. Manuel transmission model has 3. I can find only one for my HST model. It is not diagramed in owners manual.

Thanks

Transmission, rear axle and 4wd drop box. 3 plugs.

Is the 4wd drop box for the front axle that you fill through the yellow dip stick on top of front axle?

 

[RickB]

No, my mistake. The model does not have a drop box attached to the rear axle housing. You are only looking for two drain plugs for the transmission/hydraulics. One at the bottom of the transmission and one at the bottom of the rear axle center section. Front axle oil change is a separate operation outside this discussion.
Do you have an operator manual?

 

[Heeb]

Yes I have the manual. The only diagram is for a manual transmission not HST

And I already have the front axle done along with the 2 front wheel final drives
