I just bought a WD and the pto works but the arms dont raise. I want to plow and brush hog with it but honestly I havent been on a tractor in 25 yrs. Any help would be greatly appreciated. Could some one tell me where the fill holes are . Iam pretty sure theres one right below the batterybox inside the frame but IDK how many their should be.

I'm surprised no one has answered yet.

There are three oil compartments on a WD.

The very front one has a short dipstick on the left and hold hydraulic oil.

There are two rear compartments for the rear end and transmission. There are 2 fill holes for them on the left. These fill holes are just a plug with a square head. You fill them to the very top. These two rear compartments are connected through a bearing so the oil equals out between both.

The hydraulic compartment takes hydraulic oil. The rear compartments can take hydraulic oil or gear oil.
