#John deere 550 dozer with 3pt hitch series#
So, who was I to argue with Deere?, next machines were Komatsu, Cat and Hitachi.ģ point hitches were available right up to G series from Lindex. The local dealer came up with a memo from Deere that showed all the parts for a PTO disconnect for a 450E, but when he asked if Deere would build one on the next production run, they told us to take a hike. An interesting aside to this is that in late `86, I wanted to trade up to a 450E. Drive gear 30 teeth, driven gear 57 teeth on 450Cs, So at the mark on the tach., what you see is what you get. For 450Cs, Ds, and Es at the correct rpm you do get an honest 1000 rpm on the shaft. Push the pedal to the floor and the PTO stops. So, if you get into tough going, you can slow, stop or reverse the tractor with out stopping the PTO. That is, push the clutch pedal to the first stop and the machine stops moving but the PTO still runs. The clutch arrangement on 450s means you have a live PTO. I must of run up thousands of hours running PTO driven or 3 Point hitch attachments. My experience with the PTO disconnect has been 100% positive. When you look at the amount of machining done on this, it is hard to figure why Deere stopped drilling this hole, not cost, that is for sure. It turned out I had the one, (T58728) without the hole for the disconnect lever, but it is no big deal to drill it. Deere show 2 front transmission front cover part #s. The good news is that you get to check the transmission pump, put in an upgraded 12 inch clutch and check various other things while you are at it. I did mine, (450C) about 25 years ago and have probably forgotten something, but basically the engine, clutch housing and front transmission cover have to come out. The less bad news is that it is not that big of a deal to put one in. The shaft is even machined to take the retaining pin on PTO drive shaft yokes. The output splines on this shaft ( winch drive and PTO are the same) are the 1000 rpm agricultural standard. If there is no shaft out the back, just take off the cover and slide the shaft into the driven gear. As far as I know, all 450s up to E series, have winch drive/PTO gearing in the transmission. Three point hitches and PTO s have always been available, right up to and including G series machines. So other models, especially torque converter drives on 550s etc., I don't really know enough to comment on. Having said that, I think I have a decent understanding of only 450C,D, and E series. My experience has been different than many opinions expressed here. There has been some interest in the past on 3 point hitches and PTO s.
