s.w. Wi. | 8 fwd 3 rev. 4 forwards are are lows other 4 are highs.1 low and 1 high gear in each quadrant. Syncro is O.K doing tillage and planting. Can be a pain if you are pulling a load through town. Have to come to a stop to shift between quandrants. The syncros seem to last a long time. I wish mine had a 540 pto option.
My 4630 has been reliable. |

Same here. Not sure why you'd need to stop to shift once you get moving. I've heard of a 3rd reverse if you do some hot rodding to the 4-7 range. I think a neighbor has done that on his 4010.
I like syncros, but I've got a soft spot for them because Grandpa's 3020s were the first tractors I drove by myself. I really like them for loader work as you have 4 forward speeds to work with and can just yank down into a reverse. One of Grandpa's has had a loader on it since 1967, the other was the main tractor until the 4230 showed up. Now is a chore tractor and is on the feed wagon most of the year. I don't think Grandpa has ever had transmission trouble. |

Westside, IA | Yeah they have a 3rd reverse down from 7th. Some its easier to get into than others, our feedwagon tractor it falls right in, the other 2 4020's take a little more effort. |

Jackson County, AL | We have never had a syncro issue with two 4020s, two 6030s, and a 4230. 4230 was supposed to be a quad range but its still kicking. All those tractors were 7-12000 hour tractors. The 3rd reverse was only set up from the factory on the 10 series IIRC but like others have said its there on all of them, or at the least the 20 series? I have heard that on the 10s around here that got put on cotton pickers it made the reverse fast enough that you didn't feel the need to get down on the tractor to transport a short distance. |

s.w. Wi. | I was told there is a low and high in every range. Maybe the tech who told me that was wrong. |

Cleveland, MS. Own small farm near Booneville, MS | It's called a "syncro-range" for a reason. These transmissions have four ranges with two forward gears in each range. Each of the two lower ranges also have a reverse. The "syncro" part of it is that shifts within the ranges (1-3, 2-5, 4-7, and 6-8) have synchronizers that allow on-the-go shifting. However, you do have to use the clutch. You just don't have to stop the tractor. Example: You pull your grain cart out of the field onto the road in sixth and you want to shift into eighth. As you are rolling along just push in the clutch and move the shift lever to eighth just like you would shift your pickup from third to fourth. The "range" part of the system is that when you shift from one range to another that shift is not "synchronized." You must (or at least should) come to a stop before going to the next range. Example: You are in third and you want to shift to fourth. You should push in the clutch, stop the tractor, and then move the shift lever from third to fourth. The ranges are 1-3-R, 2-5-R, 4-7, and 6-8. As someone mentioned earlier, in the "10" series (3010, 4010, etc.) there was also a third reverse in the 4-7 range. This was blocked out in the "20" series and later. Treated halfway decently, IMO the syncro-range is pretty much a "bullet proof" transmission, but that is just my experience. Your results may vary. |
