Len,
I'm having the same problem that you're encountering with your LW-7. I'll surely get in touch with you if I need assistance.
Thanks.
On our 454 4 cyl we installed a relief valve between the pump and the FEL control valve that ties in to a T connection on the return to tank line.
You can also have blocage in your lines. We had a deadhead problem with our Jinma 454 due to a faulty pressure relief valve of the FEL control valve. To fix the problem, we installed a pressure relief valve between the FEL control valve and the pump. We eventually replaced the FEL control valve as we needed the float capabilities on our FEL.
Wow! That's great news LenBo.
I have an LW-7 backhoe on my Jinma 454 and I'll surely look at making the same changes.
Thanks for the feedback!
Hi Mike,
I live in the east end of Ottawa, however, I use the tractor at the cottage which is near Gracefield/Maniwaki, in northern Quebec.
We have an access road of about 1.5 miles that we need to plow and a rear mount snowblower would be hard on the neck if we needed to remove an excessive snow fall and they do happen quite frequently up at the cottage.
I also started looking at prices for 20/25 gpm hydraulic pumps and motors and yes the cost to convert will be quite significant. As you indicated the Prince pump would cost $700, an Eaton Char-Lynn disc valve hydraulic motor would cost $850, a PAL 25 gallon hydraulic tank from Princess Auto would cost another $470 and this doesn't include changing all of the hoses and fittings – yap, that is guite an expensive modification to undertake and I don't think it would be a smart move for me if I went that route as Larry and yourself mention in your post.
Therefore, my best option is to determine if a mechanical drive to the PTO would fit, like you said, I'm surely going to need to be creative to make everything fit properly and I have the whole summer to work on it. Larry has provided me with a link to the Lorenz PTO front mount option and I've sent them an email requesting additional information. I also found this video on youtube and this could be another option for me.

I've got a challenging project to tackle over the summer to make this work and I'm looking forward to it.
Mike, thanks for your input, it was very helpful.
Okay Larry, thank you so much for your professional advice. I have all summer to review which option would be best for us.
I really like the Lorenz front mount snowblower kit that attaches to the PTO. Approximately how much does these kit cost?
Larry,
Thanks, I'll get in touch with them.
How much would it cost to add lets say a 20 to 25 gpm pump on the PTO with hydraulic motor that can handle the extra flow and pressure associated with it? I assume that I'll need to change the hoses and oil tank to accommodate the additional oil flow requirements?
Larry,
That would be the ideal setup. No hydraulic adaptation required, it runs directly on the tractor PTO. What tractor did you put these on?
Bob,
It's doing both not throwing snow far enough and bogging down. We're travelling at a fairly regular speed for snowblowing not overfilling the auger area. Our tractor has creeper control mechanism and the tractor is running between 1000 and 1500 r/m. I don't have a clue if the PTO pump transmission is an underdrive or overdrive. It just feels like both the PTO gear pump and hydraulic motor are not strong enough to handle the load.
