The mech that eventually did the belt replacement told his business owner (a chainsaw and mower specialist) that he would not reccommend they take on the Greenfield dealership simply because they were a PITA to work on, and he'd spend too much time with them, time that couldn't be charged out as it would appear exorbitant.

I'm considering whether we need a ride on in our new place (when this one is sold, hopefully soonish!) but if we decide that we DO, it will not be a friction drive unit! I have had my fill of them, and wouild prefer to pay a bit extra and get a hydrostatic type drive. Less hassle all round, I think.
This Greenfield has been a beast from day one, and it was brand spanking when we got it - dealer has had a couple of goes at fixing the sticky drive (which was apparent from around 4 weeks after we bought the bloody thing) and has told us that all was "fixed" but it ain't!
