Front-End Loader How do I make a 3PH Blower work on a FEL

[J_J]

How are you controlling the motor? If you are using a motor spool valve, you should be OK. If you are using a separate valve like a flow control valve, you are OK. You can not use the FEL valve work ports as the valve blocks the fluid from the work ports. You also need a way to keep the valve engaged. A motor spool valve with detent is the way to go. A solenoid motor spool valve will also work.

You could also use a double relief valve across the motor.

How are you controlling the motor?

Once again a whole new area for me.

I thought I would have the PTO pump connected directly to the hydraulic motor and, when I engage the PTO, the pump would pump and the motor would turn. Voila! Sounds simpl eto me but maybe it is too simple.

Have I missed something about valves?? Spool? Relief? etc?

You could do that , but is not advisable. If you hook everything directly, you do have some control, like PTO rpm. If the hyd motor stalls, the pump is still trying to force fluid through the motor. and something has to give. A double relief valve is advisable to at least save the motor from damage. If you stop the flow from the pump, you need a place for it to go. If you have a 2 speed PTO, that is another way to have some control.

I was thinking the same thing and found this in a preveous thread.

Front Mount Kits

I have contacted the company to find out if this would work with my tractor and blower but they have yet to respond. Has any TBN'rs tried this setup?

I have seen this used on snow blowers before and the idea is not new. If you want to get the most power (greatest efficiency) to your blower, IMHO this is the best way to get it done and maintain durability. This method will way outperform any hydraulic solution unless you use big pumps and hp to make it work. By the time you buy the pumps, hoses, valves, releif curcuit, reservoir etc, the cost will get rediculous and you still won't have the performance and of the direct pto.
I have used hydraulic attachments (finish mower, tiller, brush mower, trencher) on my TC which has 28 gpm and the power to the attachment is nothing compared to the pto power put out by my 35 pto hp CUT.

the very least you would need in your above system is a relief valve so if something stalled the blower the pump pressuse would not spike above whats safe.
These reliefs are also built into most spool valve. A system like JJ mentions would also allow you to circulate your reservoir oil though the pump and tank to warm it up b4 you turned the blower over. Allowing the system to warm at low pressure will extend pump and motor life as well as save your clutch (if applicable)

Bob, you might check out Cross pumps. I'm putting an Erskine blower on the FEL on my JD5300 which has 50hp.

Interesting.

Which pmp are you using? How much HP are you wanting to generate? (I only have 35 at the PTO) Where are you sourcing the pump?

They aren't cheaper that PRINCE but, if I am reading correctly, they may be more powerful???

Thanks
Bob

If you have 35 HP at the PTO, the pump efficiency at 95 % will give you 33.25, and when that power is transferred to, and developed by a compatible motor, it should be around 28.2 HP. If that is enough to power that blower, you should be OK.

Does anyone here know about Chelsea PTO pumps.

A fellow not too far from me has one but I can't make any sense out of the numbers he sent me.

He wrote
THE PUMP IS A CHELSEA & THE #S ON THE PUMP ARE ,
#500-2823
#05 31 77
#48 STAMPRD ON IT,
1 1/2" SUCTION HOSE
3/4" PRESSURE HOSE.
ON TOP OF PUMP IS #2233

Says it was used on a Tilt and Load truck.

Any ideas what these numbers might mean? or where I might find more information about these pumps.

Opinions on whether it is worth a look?

Thanks
Bob

should be around 28.2 HP. If that is enough to power that blower, you should be OK.

Thanks J J - that is what i am hoping for. The folks at Michigan Iron seems to feel my blower will work just fine with 25 to 30 HP and they have actually dome this with a KIOTI DK 45 and a Meteor 75 blower. Here's hoping.
