I have a question

[jacob.karau]

I am looking at a 40c that is a four roller and I am looking at a blade for it I have found a john deere 61 blade and a john deere outside blade the guy said it is not a holt so what number would it be and what and which blade would be better on the crawler I am looking to push a little dirt and old cement not to hard of work. Any info or opnions greatly appreciated thankyou.

You better make sure the outside arm is a Deere, there was a host of companies that made them. If it is a Deere, it is a 602, and that is kind of front heaby on a 4 roller crawler, especially a 40.
I would put a #61 on it, they are adjustable for 4 or 5 roller, and would put a lot less stress on things.
