OK... gonna blow u away.. that does NOT have a hydro tranny.. ur tranny only has forward.. neutral & reverse.. the 8 speeds ur speakin of is done by a couple belts on a variator drive system.. it is a crappy system as it eats up the belts..
I will add this.. both drive belts on the variator should b changed at the same time so both grab their best.. I found it a PITA to change them..I was gonna sit on my hands but whirly dropped one shoe. I read a scathing story about a fellow who bought one. Said he ruined three "transmissions" in three years. I'm pretty sure he was talking about belts. He was very, very unhappy with it. However, if it's just a belt per year and it's not a monumental chore to change, I guess that's a doable deal. He had bought an extended warrantee and all the work was done by the guys he'd bought it from. I guess they were replacing belts but he thought they were replacing transmissions.
well.. that machine was made by MTD.. there should b a model ## on it possibly under the seat.. use it to find out ur parts needed..So aside from the belts are these trannys half durable? If someone could post an exploded view of the belt setup that would be great!
Also I'm assuming the parent company to yardworks is MTD?
