Following their giant-killing Waddilove Cup win over Raw-don, Harden face two more tough matches this weekend.
Tomorrow they take on Colton one of the clubs fancied to take the Division C title while on Sunday they return to cup duty with a visit to early Division A pacemakers Adel.
That may well prove a match too far for Anthony Bairstow's side but with Colton struggling to find their form while Bairstow and David Dawson are putting together consistent performances, Harden could well pile the pressure on leaders Illingworth.
Ilkley, whose excellent start to the season was halted by Illingworth last week, face an improving Menston side.
Ilkley have Aussie Simon Schwerdt in impressive form while Menston skipper Nick Thornton has had three big knocks in recent weeks.
Ben Rhydding will be boosted by their first win last weekend and will expect to repeat the dose when they face struggling Woodhouse, but Adding-ham may find New Rover's batting line-up too strong.
Bolton Villas have drawn three of their four first fixtures and may have to share the points again when they travel to Skipton, boosted by their cup win over Colton.
Four sides already in the wrong half of Division B have the chance to improve their positions when they pair up tomorrow. Thackley travel to Olicanian, with both on six points, while Guiseley and Horsforth, who are a point better off, meet at Otley Road.
Third-placed Silsden should be too strong for Bardsey and fast-improving Calverley should polish off Knaresboro-ugh, whose sole point has come from an abandoned match.
The hardest task falls to Upper Wharfedale, who travel to Collingham, who are threatening to run away with the division.
Aire-Wharfe League second-team scores: Colton 290-3 (P Dixon 122, M Boyle 46no), Skipton 162-8 (A Baldwin 50, M Boyle 4-92); Green Lane 213-7 (J Pleasance 47), Steeton 214-3 (J Higginson 78no, D Cook 54no).
