anyone have any tricks or tips on changing the hydraulic oil filter on a TN70DA. when i changed it the first time no problem. every time since then i usually get a very oily arm by the time i get the old one off and the new one screwed in.

I try to loosen filters a bit first, then place a small plastic garbage bag around the filter, and continue unscrewing from the out side of the bag. Unfortunately some filters are in a tight place and this is not possible. At that point I keep a roll of paper towels handy and do as best as possible. Some filters are placed in such odd/tight places one wonders what the designers/engineers were thinking. If they (the designers) had to work on these machines I'd bet replacement parts such as filters would be more accessable.

I had a similar problem with my TD95D. RickB, a former NH mechanic and great contributor to this site suggested using a ramp to elevate the side of the tractor that the filter is on to preclude this. I haven't tried this yet as I have a few hundred more hours before I have to change the fluid and the filter.

I poke a small hole in filter before removing it and let it drain in pan. This takes longer but it works, you can even be picky to were you poke the hole so it drains in an area that has nothing for the oil to land on.

you can slow down the rate of fluid flowing out of the "tank" by making it difficult for the fluid to get out of the hole.
How do you do that you say? Well one way is to find on your tractor the transmission/tank vent. I know where they are on Kubota's (under the seat) and Kioti (built into the fill cap) But I don't know where it is on a New Holland. BUT if you can find the vent hole, Stop it up. On the Kubota and Kioti machines I have done, I used a #8 machine screw. Now without a ready source of makeup air at the top of the fluid column the fluid does not want to come out of the filter hole. You can change out the filter, and take your time. A small amount of fluid will come out, but at a pretty slow rate. Of course the fluid in the filter itself can spill if you upset the filter. Do not forget to take out the stopper screw before you start and use the hydraulics.
Here is an experiment you can do while sitting at a restaurant. Take a drinking straw and push it all the way down in your drink. Now put a finger or thumb over the top of the straw, and pull it out of the drink.. It is a Miracle, the fluid does not run out the bottom of the straw, defying gravity. Now release your finger from the top end of the straw.. here comes the fluid out the bottom.
Lots of other ideas out there, but this one as near as I can tell is all my own and it works.
