Chris Wilder's men looked on course for a sixth straight league win when substitute Onome Sodje struck his first goal for the club with just 11 minutes left.
The Barnsley loanee headed home Adam Chapman's free-kick from close range. But Todd levelled from Sean Clohessy's left-wing cross.
A bumper Raymond McEnhill Stadium crowd of 2,677 was boosted by some 1,000-plus travelling fans, who were left frustrated at the end.

Boro took the lead in the 6th minute when Matt Crabb exchanged passes with Simon Johnson before firing a shot through the legs of Kevin Pilkington from just inside the area.
The lead lasted just 3 minutes though as Tom Craddock drove a cross across the face of goal and Matt Barnes-Homer got the decisive touch.
Craddock was the creator again in the 19th minute as Luton took the lead. His shot was saved by Danny Knowles but Kevin Gallen was on hand to tap home the rebound.
Luton made it 3-1 with a carbon copy of the second goal. This time Barnes-Homer's shot was saved by Knowles and Gallen once again took advantage to stab home the loose ball.

Robbie Matthews pulled one back for the visitors in the 68th minute but the Harriers were unable to fashion an equaliser.
Crawley Town striker Charlie Ademeno scored a sensational hat trick in the first 6 minutes as they won 3-2 at struggling Grays Athletic.

Ademeno then capitalised on a mix-up in the heart of the home defence before rounding goalkeeper Preston Edwards to make it 2-0.
And a minute later he completed his hat trick after Preston had palmed out a header from Willock.
It looked like being a stroll for the visitors but Grays showed plenty of spirit to pull two goals back before half time.
