Well I believe it is a TD 340 (after research I found a photo not going to go that far fixing it up), it is a 4 cyl Diesel and has 5 rollers on the bottom (1962), unknown if it has a reverser or T/A (torque amplifier)it is a 5 speed. The widowed lady told me to take it for $500 Others have taken her to the cleaners and never paid her as they promised (LOSERS) there are extra parts too she said unk where but they are around, she is in a nursing home right now. it has a 6 way inside blade and the cylindar shafts look very shiny. Dont know if it starts like I was told, but they said it doesnt move forward or backward. Maybe not enough Hyd fluid in T/A? or maybe the tracks are stuck to the sprockets or rollers or what ever i do not know, any suggestions. be welcomed to use it around the property to clean out the stock pond and fill in arroyos(the washes). Anyway thanks for all your help and suggestions.
