so does anybody know why tractor manufacturers turn the oil filters upside down??? it not only makes a mess when you change it,,,,BUT,, every time you start the motor it has to fill up before you see any pressure,,,that can't be good for the motors bearings when it sits for a week or more ocharry

If you purchase a filter with a good anti drain back valve that shouldn't be a problem. I agree with the rest. It's a mess to change them and you can't prefill a new filter. I suppose they just didn't think it was a big deal. |

this tractor has a agco filter on it and you can hear the oil draining out of it,,,really not looking forward to changing the oil,,,,,maybe they let them drain so you don't have a mess,,,,oh sure i go this tractor late this spring and i want to change the oil before winter,,,,so i might check into using a different oil filter,,,,i really like K&N stuff so i might see if they have one for this 170 ocharry

| I always wondered, why couldn't the base just be turned over? Unless it's part of the block. |

ocharry: If you're considering a premium filter get an AMSOIL or a Purolator Pure 1 or a Mobil 1 filter. The anti drain back has been checked on these and they work. I'm sure you can cross an AMSOIL filter, but it is the priciest of the bunch. |

| Drain the oil and let it drain overnite. Remove the filter in the morning and you'll have no mess. |

Between all the cars, trucks, and tractors I've serviced over the years, I've seen every orientation imaginable. I'm convinced the issue must be there's no consensus on which way is up!

If I tried that, my luck somebody would come along and start the tractor!

They are engineers after all - can't expect to much. |

If that works your drain back valve isn't working. Time to find a better filter. |

I agree and don't understand. Even with the drain back valve. When you change the oil you can't prefill the filter. I wonder if it has anything to do with the old WD style filters. Since the oil pumps to the top through the stem them filters down catching debris, I wonder if it works better when gravity holts the oil down rather than oil being pumped up through the filter??? |

As far as the oil pressure on startup is concerned there is a solution. My dad installed a preluber system on his big JD tractors. Just turn on the switch and the pump pushes oil through the whole system. Run it twice when it's cold outside. Then everything has oil and no dry startup. That was twenty years ago so I'm not sure what they cost or if they even still make them. Just my two cents if anybody wants to know. ------------- Warning! Blind man with a tractor! Head for the hills! |

| In the case of a D-17 gas (full-flow system), all that anti-drain back rubber flap does is keep any dirt from draining back to the oil pump. When it sits overnite, all the oil exits the filter via the clean oil line into the hollow camshaft. It's all gone by morning if not sooner than that. |

Well the other day it was hot...I got off the tractor and checked some stuff in the back...when I walked back by the engine..I could actually hear the oil dripping back to the crank case I like the idea of a prlube set up...where do you get them and how do they hook into the system??? I will also check out the other filters with a better anti drain back vavle Ocharry |
