Hydraulic motor advice

[Dave M7040]

I re read your thread from your first post.

While all discussion has centered on your vision, I think you should consider a simpler approach of adding a gas engine mounted on your blower to drive it.

There are products on the market. Converting your own is possible. Now you have no drive line or hydraulic losses. Most super big blowers used by airports and municipalities have their own engines and can be carried by big loaders. The loader is easily returned to bucket work.

Call them and talk to their support department, I have a valve that I got from a forklift and I was able to get the specs (max GPM/Pressure/Open center/Power Beyond) with a phone call.



Parker might be able to tell you how much their pump “is capable of” but they cannot tell you now much 土ou really need for what you are trying to do

Selecting a pump because “it is what I found (cheap)” isn’t the direct path to being happy with the results

Some times there is no choice (funds) to get all the new and fancy stuff... You just get creative and make it work.

It's actually fun to accept challenges like this.

I made a hydraulic broom for my tractor at the time, I just needed around 100/150 RPMs on the brooms but all I had was a hydraulic motor that would give me around 2000 RPMs but I got it for free.. Well, I just made it work and it worked awesome. Some might think it was overkill since I was using a Parker F11 Piston motor

The laws of physics are laws. Not suggestions.

I can稚 use a 3 Hp Briggs engine to repower my 3/4 pickup and just say I will 杜ake it work

No, but it will let you see if it will be "close enough" to get the job done.

You can, do it with a 6.5 HP engine, it just wont go very fast, or accelerate very well:

I think chooseing a hyd motor and then trying to match parts to make everything work is just plain working backakwards. What is the recommended hp required for the blower you are trying to use and what rpms are required to make it run properly. You can take those two numbers and do the math and come up with required torque/size hyd motor you need. Once you know how big a motor is required, you can again do the math and determine how much flow is needed to reach the desired rpms and how much hp is needed to turn the pump. Simply buying a large hyd motor and trying to make everything work will be a expensive exercise leading to much fustration with poor results.
