There's lots of them:

bíta : beita
brenna : brenna
drekka : drekkja (cp. English drink : drench)
falla : fella
fara : foera (Modern: færa)
renna : renna
sitja : setja (cp. English sit : set))
springja : sprengja
sofa : svefja
vinda : venda (cp. English 'wind' : 'wend')

The causative verbs (the ones on the right) are weak. They take their
root vowel from the past tense singular of the strong verbs on the
left) + i-mutation. Sometimes there's a simple causative difference
in meaning: brenna (brann) "to burn, be on fire" : brenna (brenndi)
"to burn, set on fire". But sometimes, the meaning has drifted, e.g.
'drekkja' "to drown" -- cognate with MnE 'drench', which also meant
"drown" in Old English.
