Either set the TERM variable or better: use top in batch mode with 'top -n1 -b' and receive output on stdout. *Note if you want to run top on several hosts continuously then you probably suffer from "using the wrong tool for the right job" syndrome in the sense of never having heard of Monit, Nagios, SNMP, etc, etc...

In this case this should work:
Code:
ssh user@some.machine 'top -n1 -b|head -25'
