hmm. I don't think the Clutch has anything to do with the engine brand. Most are twin disc _ Rockford etc. What brand is the clutchIJ The Deutz (unless it was 'rigged' ) has a standard ASAE bolt housing and used the same clutch as about every other brand avalable as they have been a major supplier of irrigation engines for decades. If IPSCO can't help try BEBCO 6627596493 ask for Bill Jr or Billy or Olivers- Prarrie there in Stuggart.
