A while back I posted asking about weather or not my NH 1725 had enough poop for a 3pt log splitter. I don't have the spec's but I believe Northern's reccomended G.P.M. was 11. My tractor's is 7. I'm not in the business of log splitting so I think slower won't be a problem. I'm about to have my dealer add some rear hydrolic connectors and buy Northern's splitter. Any last thoughts out there? Thanks.P.C.

Log splitters have a differential hydrolic control valve. The lower rate should only affect the speed at which the ram moves forward. In general they are a relatively large cylinder and therefore require a lot of oil volume. I would think that you may over and under fill the hydrolic res. with each stroke on a small tractor.
I have a large tractor (65 hp) which I normally use with the splitter. I have hydrolic remotes but use a PTO pump on the splitter. I would recommend getting the unit with the pump. The cylinder sits in a lot of dirt and chips etc. I do not want that in my tractor system. The PTO pump is alot less than and easier to rebuild than the one on the tractor.

Paul, the NH model sticks way out the back and requires you to lift the logs up onto the platform. I don't know what you've got, but I certainly can't be lifting anything over 1 foot diameter green logs. I just bought the 3pt splitter from TSC, for $550. It tilts vertical so I can just roll the logs up to it. It also came on a metal platform that it sits on when you let it down. It's worth the extra $150.

I like the ability to set up the splitter in a convenient, flat, level clearing and then use the tractor for gathering logs or pre-cut pieces and bringing them back to the splitting site. Split wood can then be loaded directly into the loader bucket for transport to the woodpile, if necessary. This versatility added to Peters' concerns about 3pt units strongly favors a self-contained, towable unit. I also prefer the units that can be used in upright mode, especially for large or heavy pieces. -Ken ....

The oil requirement for a large splitter is a good point. Many PTO pumps have smaller reservoirs than most compact tractors, so reservoir size can be an issue with PTO pumps as well. There's also another possible issue. Awhile back on another board, somebody was having oil heating problems while running a splitter from a PTO pump. Somebody commented that the pump reservoir probably was too small. A small volume of oil would build up heat, and a small reservoir size would not dissipate it as well. He said that tractor hydraulics often worked better because there is more oil in the system, and the larger cases dissipate heat better. That may be true, but it also is true that a tractor probably shouldn't be driven with a splitter extended because there may not be enough oil left for the transmission. ....

I also use my 3rd srv. for my log splitter and am somewhat concerned about debris entering my hydrualic system from it. Does anyone know of an inline Hydraulic filter one could hook up that you wouldn't have to worry about bursting? I think one on the return side would work fine (which is where you'd want it anyway) but im not 100% sure. Anyone know what kind of pressures are on the return side? ....

I'm guessing around 100 lbs., but potential pressures in the return line would depend on how the system is plumbed. My 3ph is downstream from the auxiliary system. The return (power beyond) line from anything run from the aux system could see anything up to the system relief valve pressure if the 3ph is used. A system where the return line goes directly to the sump would not have this potential problem. A test for the plumbing in a power beyond system is to see if the 3ph works while operating the loader. If the 3ph doesn't work, then the system is plumbed like mine. With mine, there would be potential for exploding most filters if the 3ph was accidentally bumped into lift position. ....
