well as for myself i realy like to see over 3000 hours of HARD work out of one . and i can tell ya this that yes they do start when it is realy to cold to be out side but that is farmen and if ya plan to use it to grind feed on the 87 or use what ever for oil hope that ya have a nice warm shop to work on it . like i said before on here after having the gas of today lab tested at my expence and revieuing the test results on just how hot 87 burns over the 93 and the end results on the NEW pistons that you get today they will not take the extra heat. number one the Org. pistons were a Forged piston the new pistons of today are of a Cast design . Forged can handel heat better as it will allow heat to be transfered to the cyl. walls faster and allow the top of the piston to cool faster where as the cast piston is way cheaper to make and does not allow the heat to transfer to the skirts as fast holding the heat on top . I do not care where ya buy your kits from because they all come from the same mold , if ya go to your friendly Case I H store and buy them ya payalmost twice as much for the kit as you do aftermarket just so ya have the I H part # stamped on the top as forthe #'s on the side or casting #'s they are the same as the ones ya get from the aftermarket suppliers . This reg. gas is not even good for older trucks that try and work for a living . As for seing combustion temps showen up on the tempure gauge that will not happen as that heat goes up so fast that it does not have time to sink in to the coolant to show before damage is done. Yes it cost alot more to buy the correct gas today , but keeping it running and not spending money on overhauls or pullen the head to replace burnt valves every two weeks as we have been down this road a couple times tomany with our owen tractors and also customers tractors that now we have switched over to the low ash oil and run the 93 they run like they should and up till the fuel has gotten out of hand we run them every day . So for the time being we are going to try and use some of the 4 other older tractors to try on the haying and see if we can reduce the operating cost a littel bit plan on putting my S/H on the hayrake have the old Cough choke John Deere 720 diesel on the haybine and that is not working out well as it does not have enough hyd's to lift it going to look into that this afternoon. parken the 706 and the 1066 maybe pull the wide ft. out from under the 706 and putting it under the 806 going to try and get Dusty's old H running again and put a good tune up on the old J D A for pullen wagons and install a ft wagon hitch on it to PUSH the wagons up to the barn . If ya want fuel economie then best go find a old MD - 450 D or a old 720 - 730 or some old David Browns or dawn your Blue shirts and pants with no buttons and get a couple teams . Also i realy do not like rebuilding and engine every year as we put on more then a 1000 hours a year on the 706 a year.
