Do 7020’s if taken care of properly last over 6000 hours? Engine? Transmission? Or should I stick with a lower time unit? Personally I think lower hours as I am really a fussy guy. Opinions please. Thanks. Dana ------------- Blue Skies and Tail Winds Dana |

| The most neglected system on those tractors is the cooling system. Failure to keep treated antifreeze or use of a coolant filter will in time lead to cavitation erosion of the wet sleeves. Now, and engine that works hard all the time (heavy tillage) will last a lesser amount of hrs as compared to an engine that only makes hay all the time. Cooling system also includes keeping the radiator core clean and fan belts tight. Those engines don't usually fair very well if run hot, as it can loosen the copper injector tubes in the cylinder head causing troubles there with coolant disappearing. |

Remember they are 40 year old tractors. 6000 hours would be only 150 hours a year. Find one with too low hours I’d doubt the authenticity of the hours. I’ve always been intrigued by a 7020 but sorta struggle to justify one. Ohh who am I kidding if I found the right deal I’d be tempted. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| There out there yet I found mine with 4,600 on it and put 300 hrs in the year I have owned it. Another thing is do not over look the trans filter. The previous owner was having trouble with reverse and then it wouldn't move at all. I found the trans filter plugged solid and changed fluids and now it will only slip in reverse under heavy load. |

| Well I was also thinking about up-grading from my 200 to a 7010/7020 to have a nicer cab but then a light bulb went off in my head. A really nice one would cost 10/12/15 thousand and then what if something castastropic happen like transmission, rear end or engine failure? No dealers or mechanics around here will work on AC's even if you are lucky enough to find parts. Some guys can fix these kind of things themselves but what if you can't? So I decided to hang on to my old 200 till she croaks for good and look for a GREEN replacement. Dealers are plentiful and it might cost a small fortune to get it fixed but it can be done. Just pay the bill. Please don't get me wrong--I love the old AC's as much as anyone but they are a part of history now anyway you look at it and even the last ones made are getting very old. |

| KyAllis - nonsence !!! Im only joking now , but do understand your thinking - my thoughts of the older AC tractors is to stay away from Powershifts as they are more complicated- Power Directors are alot tougher and parts can be made cheaper- in my opinion - one thing happening now is the Kubota older tractors with the slider trannys and easy shifting are becoming in line with older stuff price wise,, and usually parts are available if needed, with shops supporting those tractors |

What about Laker’s in Indiana or B&G in TN? I LIKE my Deere but not afraid of the true orange. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

I’ve had two PD’s over the years. Got irritated with 7080 and shipped it and if I find the right Deere I’ll ship the 7580. We got three PS and prefer them hands down. Might be reason most later model tractors industry wide were power shift till CVT and IVT came out. Bought my 8050 with tranny issues closest salvage yard had a 8030 PS we cooned the guts from. BTW my 7080 had PD issues. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

| The last year of the 8000's built, Power shift units were over 80%. |

| I have 3 8000 series power shifts. Had one since 93. Never an issue with any of them. The big one is an 8070 FWA and pulls hard. I’m not scared. If I find the right 8030 I will have the complete series. |
