Farmall Cub

I have an IH-1000 loader on my Farmall 100 and it has only been on there since spring. It worked good up to a week or so ago. It was not lifting well or pushing the the front bucket up and forward. I checked the hydraulic fluid and it seemed low so I put some in it today and it seemed to help but now the return line is pulsating the whole time unless you are lifting or tilting the bucket. It makes a pulsating sound at the tractor also and you can see the hose bouncing. do I have air in the system or is there another problem? any help or suggestions would be great.
thanks

Chad:

Although I have no experience with a loader yet, I have unfortunately been learning hydraulics the hard way. It kinda sounds like you have air in the system. Try bleeding the system and check the level again. You may have to do it a few times to get the air out.

Let us know what happens.
