If I said that I "mispoke" digitally. I thought I said no "steering clutches." The Case 310 uses a Clark transaxle- pretty much the same as what Oliver uses in HGs, OC3s, and some OC4s and in Terratracs. No steering clutches, just two wet brake bands. I say "some" for the OC4 because the OC4 had a choice of two different steering/drive systems. The "Spot Turn" system DID have clutches but it is a wet-clutch system as I recall.
A big problem with old crawlers with dry steering cluthes is they get can stuck when sitting around. Like use in Deere crawlers up to through the 350B or 450B series, Allis Chalmers HD3 and HD4, etc.
