Is there a way to specify multiple spaces as a field delimiter with the cut command (something like a " "+ regex)? For example, what field delimiter I should specify for the following string to reach value 3744?

$ps axu | grep jboss

jboss     2574  0.0  0.0   3744  1092 ?        S    Aug17   0:00 /bin/sh /usr/java/jboss/bin/run.sh -c example.com -b 0.0.0.0

cut -d' ' is not what I want, because it's only for a single space. awk is not what I am looking for either, so how to do this with cut?
