 Topic: 8070 hydralics

I'm going to hook a spray rig up to my 8070 that I have been using with my 185.I know I have to change the hyd pump so that it will be using a closed center hyd that the 8070 uses.On the 185 I just used a rubber strap to hold the hyd lever engaged.On the 8070 with the closed system how do you keep the hyd engaged?

It should stay engaged without any strap or anything, Trev.

You should be able to adjust the flow in the cab to get the pressure you want. I think if your pump has a adjustment, it should be full flow and then adjust the flow in the cab to control the max pressure. The hyd lever should stay in detent and should work fine. It works great in my 8050.

You must adjust the detent kick-out tighter so that the lever stays locked in by itself with no tarp strap......read your owners manual.

On the hydraulic motor on the spray pump there will probably be a by-pass screw with a jamb nut. Make sure that is turned all of the way in, then like others said, use your tractor flow controls to dial in your pressure. And like Dr. says, if the hydraulic lever kicks out, set up the detent per operators manual. Darrel

Someone just posted on agtalk today about running the pump return back into the bottom sightglass hole to keep the oil from overheating when spraying. Just thought Ide throw that out there.

MACK, could you comment more about running the return oil back through the tractor hydraulic couplers and not through the sit glasses. I was looking at running a hydraulic driven sprayer pump with a 7020 and would like to know the correct way to do this. For me it would need to run it 8+ hour a day on some of the warmest days and I don't want to overheat the oil. Thanks!

I run a Redball 680 with a 108' boom on a 7045PS. Turn the detent screw in and this will keep the lever held in place. I was told to run the lever in lower and push it ahead to float to shut it off. Use the first or right hand valve in the stack. We return the oil through the valve, but I have seen it done retuning the oil through a siteglass. Wash out your radiater and oil cooler before you begin. And may all your spray days be windless days.

You will get a little more cooling of oil by going back through valve. MACK
