I have seen Front End Loaders on them and have heard of others mounting Loaders on them, but I would not recommend it. The Tractor itself was designed for a 2-Cylinder Gas Engine. The 2-53 Detroit Diesel is a lot heavier. If it were just the Loader itself it would be one thing, which will also add wieght, but then you are going to use it!! In my opinion, the Engine, Loader and weight of the material in the Bucket are a little too much for them. They are also known to not have the strongest Front Ends.
But I wouldn't doubt if there are others that may jump in here and say they have a Loader on theirs and it works fine, but the above reasons are actually stopping me from installing one.
