Repowered the processer today with a Predator 13 HP . The old Briggs was getting tired and couldn't pull to 2500 psi . I put a 12 in block in cross ways and it held right at 2500 . Ready start cutting for next years wood .

You will like that 13HP  motor I have one on a cord wood saw and it has a lot of hours on it and zero problems. I run 20/50 Mobil one in it.

I have had good luck using Mobil one in air cooled small engines. Have a Kohler 25 with a couple thousand hours on it and in 70 hour oil changes it never takes any oil. Have a 25 year old 16 Briggs twin  that I should have put a hour meter on it but didn't probably gets 200 hours a year on it and all I used in it is Mobil one change it twice a year and it doesn't use enough oil to add any between changes.

one thing ill tell you about your motor is take that vent tube that comes out of the gas tank and goes to the back of the carb other wise when the tank vents in the sun it will fill the crank case up with gas and hydro lock it i got one on my walk behind concrete saw and could not figure out how the gas getting in the oil after 3 oil changes in one day   i was sitting there and heard a gurgling noise and found it took the line off the top of the tank and that little vent shot gas a foot or so out of it so mine has been on hooked for about 6 years now

Just another bump for 2019 firewood season . With a machine that's built like this there are always things to change . I will be bringing it home during Deer season to change to a auto cycle valve . The linkage works but limits the stroke . Will need to start on a new splitter so I can change it out during breakup . The beam and wedge are just not strong enough. I have twisted the 1 inch by 6 inch main wedge . Right now by myself I am putting 2 cord on my dump trailer in just over 2 hours . that includes carrying the wood from the pile and loading the deck 4 times .

 I assume when your talk autocycle your talking about the prince valve. I have owned two and probably wouldn't own another. The first one was a early model and they replaced it twice on the company because it wouldn't ever work right. The third one worked ok but took some adjusting on and off. A buddy bought that splitter and he didn't like messing with it so I took it off and he sold it. The one I currently have is on my processor and you have to adjust the pressure on and off. Right now it works good when you first start out and as the oil warms seems like the o'rings swell and it won't kick out when it extends. So I adjust the pressure a little and it will work again.Next time I start out I have to adjust it again. I do run a cooler on the processor to keep the oil temp in check as I run it a lot in the heat of the summer. I think this winter I will buy a o'ring kit and put that in and see if it will help. Just food for thought before you spend your money.

It's on the shelf already . I hope it works . I have been told by other MFG to mount it vertical . That's what I am going to try .

I hope yours works better than mine does. I not for sure why they think vertical mounting the valve would make it work better. When winter sets in and it gets a little slower around here I may have to call them and see if they think vertical mounting and a new o'ring kit in mind would make it work better.The idea of auto cycle is great when it works but if you always have to be adjusting on the valve that doesn't work so well. Its a real pain when my helper is trying to run it and I am on the skid loader and he doesn't know what to do when it starts acting up. He doesn't want to start adjusting it.

I know a guy that runs a Wolf Ridge splitter and has 1800 cord through it . Has had no problems with it . Chris from Wolf Ridge will be my first call if I have a problem .
