Hello catotonia39
A warm welcome to these great forums.
This question has come up before.
Without images, comment is difficult, or impossible.
Rovers should have model plates - this info is required for comment.
Changing engines is always the better option than fitting a cutter deck to a different model.
That is asking for trouble.
So, please see if you can find the maker's plates and provide images.
Hope this helps.
