 Hydraulic Power Equivalent

Question: I'm fairly familiar with how a hydraulic system works but would like some of you number crunchers to check my work. I have a Farm King 740 - 74" category 1 rear snow blower. Needless to say, it's hard to do close up work staring backward over those 18.4 x 30" rear tires. I am trying to figure out a way to put a similar but hydraulic blower on my loader. Switching out the quick hitch is no problem BUT my hydraulic specs ARE according to my figures. My tractor has 22.5 gpm total flow with single scv's rated at 15.9 gpm. Here's the problem: 15.9 gpm x 2830 max. psi divided by 1714 = 26.25 hp at the outlet. Enough power? Further, I've understood you should have a reservoir equivalent to your gpm in order to use a continuous hydraulic motor. Mine is about 11.5 gallons. Anyone have any experience in this area to confirm or refute these numbers?

I have no answers, but maybe some comments.

-I think you'd need an auxiliary pump and reservoir. I assume you have a remote for the chute direction.
-You might need some extra weight at the rear.
-An option to consider is feeding the PTO forward.
-Another would be to power it with an electric motor, though you'd have to look into a supplementary alternator and maybe an inverter.

Aurbach, thanks for the comments. There are companies like you mentioned; Erskine, Puma and Deere's 4000 series to the name a few. The scary part is the price of these self contained units. For example, a trade price for my Farm King (used once and retails for $2995) was $8,000 to boot not including the quick hitch adapter. This unit has a 25 gallon 3 point hitch reservoir. I don't want one with the pto geared underneath, but they're pricey too. I'm wondering if I can get by without the extra money or ruining my tractor's hydraulics. Thanks again.

LWayne;
My experience with Deere 7 and 8 thousand series would tell me yes, they have pump capacity up the wazoo, and even they had optional higher capacity pumps from the factory only.
I have no experience with your series, but I have my doubts that unless a factory high volume pump was in the tractor that you can get that much out of the standard system.
I have the pumps, motors etc, to build a system such as you want driven from the mid PTO of my 4310 but just another of those haven't gotten around to things so far.

It's been my experience that the figures the manufacturers publish are, to put it politely, optimistic.

Almost all of them are "bench test" figures. In other words, just the pump alone can make 'X' gpm at 'Y' psi.

The problem is, in the real world however, the figures are vastly over-stated.

IMHO you should take the stated figures and divide by at least 2 if not 3 to get the actual number.

Best of luck.

Have you checked the price of pto hyd pump and tank to provide the hyd flow and pressure you need? For less than a $1,000 including hoses and fluid you should be able to. If rear weight is needed the tank could supply that.

As to your question on size of reservoir compared to hyd oil flow, it is my "impression" that is to help keep the oil temp down. For snow blower that might not be an issue.

I'll put it another way. Nobody likes to work staring backward. But 9 out of 10 blowers are rear-mounted. Do you not think there's a reason for this?

IMHO there's 3 good reasons for most snow blowers to be on the back of the tractor;

1) that's where the tractor manufacturers put the PTO shaft and 3pth needed to carry it,

2) customers want the lowest possible price, this means less mechanism,

3) most tractors today have a FEL on them, this makes front-mounting a blower both complicated and expensive.


Best of luck.

Seems that in today's high-tech world, it would be cheaper and less complicated to mount a couple of rear facing cameras with monitors up front.

I've been wanting to mount a camera on the front to help aim the pallet forks. That would be pretty nice, but it would have to be ruggedized.
