Thanks for reply.  My sawmill has a 56 inch blade.  We did have a Farmall 560 that would run it o.k.  But it was a diesel and had starting problems so I traded it in on a Bobcat.  I did run it a bit with a Farmall M that had M&amp;W pistons (50hp)  ?  but it had to be babied a lot in our oak logs.
Did the 880's have about 60 horsepower or more than that?
