Push student to get spade (6)
I believe the answer is:
shovel
'spade' is the definition.
(I've seen this before)
'push student' is the wordplay.
'push' becomes 'shove' (shoving is a kind of pushing).
'student' becomes 'l' (as in L-plates for learner drivers).
'shove'+'l'='SHOVEL'
'to get' acts as a link.
(Other definitions for shovel that I've seen before include "Tool for moving, earth say" , "Tool to be found in hovels?" , "Tool for moving, eg, coal" , "Scoop for lifting and carrying" , "Tool for scooping" .)
