IJumbo Swivel Wheel elenzelwa imishini yezitini iJumbo MK2 neMK3, ikakhulukazi ohlangothini lwe-opharetha. Ukusetshenziswa ukuzungezisa umshini kalula ekugcineni kwekholomu yokukhiqiza. Isondo linikezwe ngaphambili ngenjoloba noma nge-polyurethane; kodwa ngemuva kwempendulo yamakhasimende (kanye namathuba ekhwalithi yesilayidi nokuhlanzeka) injoloba ayisaseyona inketho etholakalayo.  Akukho ukubopha okwakhelwe ngaphakathi ngokuzenzakalela njengoba i-adaptha yamabhuleki yangokwezifiso isetshenziselwa ukubopha ukunyakaza kanye nokugcina isondo liqondaniswe ku-eksisi yalo ukunyakaza okuqondile  lapho kungavulwa (ukuthenga okuhlukile).
