Then you pretty much solved "plow" --it's from IE *bhelg- "a thick plank, a beam" which is exactly what wooden and metal-tipped wooden plows look like in Central America and other places that I've seen in pictures.
*bhlugo- > Celtic or NWB/Venetic/Rhaetic *blug- > Germanic *plux- "plug or block, plug or block shaped thing (such as a plow" which makes a whole hell of a lot sense more than "land rudder"

As many other Germanic words with initial p-, 'plug' is possibly a NWB loanword corresponding to native 'block':
- block (n.)
- "solid piece," c.1300, from O.Fr. bloc "log, block" of wood (13c.), via M.Du. bloc "trunk of a tree" or O.H.G. bloh, from a common Germanic source, from PIE *bhlugo-, from *bhelg- "a thick plank, beam" (see balk). Meaning "mould for a hat" is from 1570s. Slang sense of "head" is from 1630s. In cricket from 1825; in U.S. football from 1912. The meaning in city block is 1796, from the notion of a "compact mass" of buildings; slang meaning "fashionable promenade" is 1869. Extended sense of "obstruction" is first recorded 1640s.
- block (v.)
- "obstruct," 1590s, from Fr. bloquer "to block, stop up," from O.Fr. bloc (see block (n.)). Meaning "to make smooth or to give shape on a block" is from 1620s. Stage and theater
sense is from 1961. Sense in cricket is from 1772; in U.S. football from 1889. Related: Blocked; blocking.
