1720 oil capacity

[gravismaximus]

Looking to change my oils. Bought a manual but it dont have capacity amounts in it. How much oil should i get. Also want to change the hydralic fliuds. Book says use Fnh 134. What is it really? Normal hydraluc fluid?

The specifications are at the back of the O&M manual. Mine was pg 55, but my tractor was a 1988 1720. It said,

Rear Axle and Transmision 28.5 qts (~ = 7.13 gal)
Power Steering 1.9 qts
Front Axle Differential Case and Final (outer drive) Reduction 5.3 qts

New fluids often are multiviscosity, like 10w-30. For a tractor such as this, I like the TSC Universal Tractor Hydraulic fluid, which sometimes in the 5 gal size goes on sale, and it is multi-vis.

Don't forget the filters and note that there are multiple drain points on both the rear, tranny and front axle/final drive.
