TD6 Dozer/Loader in IH Construction Equipment Posted January 2, 2020 13 hours ago, sugarmaker said: Question: Did these have the second (front) top roller for the track to ride on? Chris, the five roller track frames have a second top idler, the TD6-61 and 62 series had the five roller track frame as an option, the TD6-62 factory loader had a longer track frame (37 links) than the five roller option (36 links). I am not sure if the older TD6's (4 roller 32 links) had the five roller frame option, I did find a picture of a TD6 with an extended track frame, it may have been shop made, if it was they did a nice job, or they may have put a later five roller frame on it. Picture is pulled off the internet of a TD6 loader with five roller track frame. Also a TD6-62 factory equipped Drott loader. Note how the front top idler bracket is, the TD6 is the same as the regular five roller frame, the factory TD6-62 loader has the bracket reversed.
