Other smaller crawlers, like Cletrac HGs, Cat D2, Allis Chalmers HDs series had some sort of suspension that would give over uneven ground. I still don't know what Deere was thinking. At the same time, the 450 had a much more massive mounting system and gave little trouble. This stopped the cracking, but now instead everything got worn and sloppy. Later 350s used a floating system where the trackframes attached by floating dowells. So, many got welded together - what a mess. They would crack, break, bolts would pull out, etc. Early 350s had the crossbar mounted solid to the track-frames. I think the original 1010 setup was the best. From my point of view, they were all lousy. 350s also went though various changes to the method of attaching the crossbar to the two track-frames. The hydraulic reverser also got beefed up.Īlong the way, 350 got an updated drive mechanism to connect the engine to the reverser - and it was WORSE than the 1010 and early 350 type. cases and side frames - and these parts also were used for replacement in the 1010s. But, replacement parts got beefed up - including stonger steering clutch housings and trans. When the first 350 came out, it had the same weaknesses. 1010 crawlers - when used very hard- tend to break steering clutch housings, crack transmisson cases, side-frames, had a weak center bearing in the reverser if so equipped,etc. Generally speaking a 350 is worth more and is usually more rugged - but it got more rugged and heavier as time went on. Thus the terms "inside" and "outside." In regard to your question if it being a 350 "changes anything", well yeah, it's a different machine. The arms that attach to the 6-way blade are inside of the tracks. An outside blade it supported by a big arm on each side of the crawler -and the arms mount on the outside of the tracks. If it is a 350 it cannot be an early 1960s crawler.
