| I am wanting to run my two vacuum motors on 1780 planter off of a pto pump. I was considering a hydraboost system until I got the price for their unit. I am now thinking I should just piece the system together myself to save some money. I seen where the two motors are probably going to require around 4-5 gal/min each so I don't need a very big system. I was looking at a prince pto pump but would like to see if others have made their own system, what they all used and how it was plumbed. I currently use my 7800 for all hydraulic functions with a case drain, it has the two dials to regulate vacuum. I am just trying to figure out how to incorporate these in the new system to allow fine tuning of vacuum. Also is it better to use 540 or 1000 rpm pump? Thanks in advance. |

southern ontario | Won't the 7810 run fans without pto pump? |

| It does but I want to get away from clutching on every pass to wait for it to lift. When vac fans aren't on planter raises fast. |

Madision County, IL | We had to do the same thing with 1780. Inztalled Ag Leade clutch contol and no longer slow down when turning.. You will also get the benefit of saving some seed. |

CENTRAL ILLINIOS | I pieced one together for a 1770 planter on a JD 8400 tractor with the pump and most of the parts coming from Surplus Center. Biggest problem was that tractor only has the big 1000 PTO and none of the pumps came that way so I had to use an adapter. Has a little wobble in it because of the adapter but been running two years with no problems. I am thinking about putting a oil cooler on it for next year because the oil will run pretty hot and with a cooler I can quit worrying about it. Bought the pump, tank, relief valve, and filter from Surplus Center then had all the hoses made locally. You will need the flow control valves to regulate vacuum for each fan if you don't have them. |

| Campbell what size pump did you go with and where does the relief valve get plumbed into the system? |

| We're running a 7200 vac this year on a great big ih 1486. The planter already had the oil cooler plumbed in but we needed a pto pump. After enough pestering and I think finding the part # ourselves, we finally got the Deere dealer to order us a pump. I think it cost about $1300. I think that pump would have enough capacity for two motors. |

CENTRAL ILLINIOS | I don't remember the pump size but I can take a look at it possibly this afternoon and let you know(it is stored on another farm). I am having a hard time remembering how I plumbed in the relief valve too but I think I ran a hose from the pressure side of the pump to a tee, with one side of the tee going to the flow control valves and the other side going to the pressure relief valve that is mounted on the side of the tank. Will look at that when I get over there too. |

Sac & Story county IA | If you had this pump hooked to a 1000 rpm pto with a double roller chain coupling, you would have about 11 gallons per minute.

You will need a flow control to get rid of some oil flow. Something like this

Plan on 10 gallon tank of oil and be ready to add a cooler if needed. |

CENTRAL ILLINIOS | I could not find any numbers on the pump but I think it is the 5.7 cu. in. Prince listed at 22.4 GPM. Will try to upload a picture. It is plumbed like I said in the post above. I ordered it oversized so I could run with the tractor at reduced throttle and still get the flow

Did you have to install a flow divider valve to split the flow after it came out of the tee or how did you split the flow between the fan motors? |
