Bought a brand new Troy built lawn tractor with 20hp Courage engine (yes it does take “courage” to build such *** and let your name (which used to be quality) give false assurances to consumers, pretending they care, will stand behind their products or that they are built to last! What a crock of *** Approx 50-60 hr and the engine blew. Oil and filters changed regularly and unit was well taken care of. Do not waste your money
