We physically pushed trolley buses on a number of
occasions when I worked on the Muni Railway in San Francisco. They rolled very
easily even though they weighed 11 short tons. Three guys could push one easily
on the level. I did it once with one other guy.

That's it.
Sometimes there were deliberate reasons why a trolley bus would need
to be driven out of the range of the poles on the wire.
There was one spot in Brisbane where there was a unwired downhill
section between two routes. It was used on a number of traction fan
tours to avoid a trip back to where the routes diverged. The bus
would be stopped on the first route at the side street, as far down
the side street as the poles allowed, then the poles pulled down. The
bus coasted downhill to the second route and was then rewired. If the
bottom intersection was blocked, some pushing was required, or so I'm
told.
On many trolley bus systems it was possible to do a direct move from
one route to another where there was trailing junction, or a right
angle crossing, where there was no direct wire connection (i.e.
inbound on one route to outbound on the other) by deliberately turning
the bus in the desired direction to the point where the poles would
almost be ready to dewire. Then the poles would be manually
maneuvered off the inbound wires on the first route to the outbound
wires on the second route.
This sort of thing would not normally be done with regular scheduled
services carrying fare paying passengers, but would be done in the
case of fan trips, disrupted running movements, or perhaps to position
a bus for the first inbound run of the day, or run in to the depot
from the last outbound run etc.
