Backhoe on 9n

Hey John, I have a 3pt. backhoe that I built on a 2N, since the minimum pressure that the hoe will operate on is 2 gpm and the maximum the N's will put out in new condition is 2.8, I opted for an 11 gpm pto pump from Northern Tools. It also gives you the flexibility of using another tractor and quick disconnect from your tractor. It seems to operate fine in most conditions, lifting the boom extension is the hardest on the old N. I can almost kill the engine when raising the boom extension. The main boom, swing, and bucket operations don't seem to bother it much, just the boom extention. The other problem I ran into was having to rebuild the lift cylinder on the N as it will lift about 1000lbs in new condition and the hoe weighs in at about 500lbs. It was lifting extremely slow if at all until the new NAA piston and rings were installed, lifts great now. The addition of a hoe will certainly bring to light all of the problem areas of you N. I'm still fussing with the governor on mine, it isn't quite right yet and I will assume that once the governor is up to par I won't have any trouble with the operation killing the engine. I hope this gives you some insight as to what you may expect. Buckeye

One of the reasons for having a TPH implement is so that you can take it off and put on some other implement. SO, since the hoe will be mounted on/by the TPH I would suggest that you do the same as several manufactures do for their TPH hoes. That is use a PTO pump. That way you do not have to disconnect ANY of the hydraulic fittings to take the hoe off. Can't get any dirt in something that is not opened up.

Take a look at a TPH hoe at a dealer and you will see how neat the PTO pump is. I have a Woods hoe that is made that way and it works very well. I like it a lot. The Zane Thang has its place, but I do not think that driving a back hoe is one of them.
