Push student to get an implement (6)
I believe the answer is:
shovel
'an implement' is the definition.
(shovel is a kind of implement)
'push student' is the wordplay.
'push' becomes 'shove' (shove is a kind of push**).
'student' becomes 'l' (as in L-plates for learner drivers).
'shove'+'l'='SHOVEL'
'to get' is the link.
(Other definitions for shovel that I've seen before include "Tool for scooping" , "Scoop for lifting and carrying" , "Excavator" , "Old clerical hat" , "Spade-like scoop" .)
