Need Help With Hydraulic Snow Blower Set Up

[J_J]

I have purchased a used 62" hydraulic snow blower to mount on the front of my 45 Hp tractor. I am trying to build a PTO driven hydraulic power pack to run the snow blower that will be mounted on a 3 three point hitch frame. I purchased a new 20 gpm at 3000 rpm pump to run this unit that needs to run at +/- 2000 rpm. I had a 4:1 gear box that I planned on using to run off my 540 rpm pto to run the pump, but just found out that it will not work to increase rpm, only reduce rpm. I have been looking for a used +/- 4:1 gear box to do the job with no luck. If I could find a reasonably priced 2:1 gearbox that can handle the workload, I could exchange the pump for one that can deliver the output and pressure at 1000 rpm. Any suggestions or feedback would be most appreciated. Thank you. Thom

A gear box runs in both directions, To increase or decrease the rpm depends on how you connect it.

540 rpm going into the I ratio side will make the other shaft turn at 2160 rpm.

To get 3000 rpm, you need a gear box with a ratio of 1: 5.5

To make that pump flow 20 GPM and develop 3000 psi, you need 41 HP.

Will 20 GPM going into your snow blower motor turn it as it was designed.

The hyd motor will develop the pressure it needs to do the job. Light snow, less psi, and more snow more psi until the motor stalls.

Here is an option, don't know the price, but gives you an some ideas to start from. There seems to be several companies selling them if you google them. The Erskine attachments unit is made to mate to their front mounted hydraulic snowblower.

That pump is 1000 RPM PTO not 540 so unless your tractor has 1000, then it won't work. The one that Surplus Center has is 540.

Uh no it is not, it is rated at 540 rpm and 595 max rpm. So yes it will work. I make my living doing this but you seem to have a handle on this, so I will go away. CJ
Oh I also own this pump so I can absolutely promise you it is 540rpm. PN# GP-PTO-A-9-6-S
To the O/P PM me and I will gladly help you with the system. CJ

My mistake, I only went by what I saw on the page of their website. I guess I am not in the "IN" group so I will leave it to others.

Sorry I was short but I deal with wood splitters and snowplow people this time of the year and with most of them you are always wrong because it costs money to fix something. Again sorry. CJ
