My mower is a 2014 ZT 1500
7012 I just got the end of June. Had some engine problems but don't know if they have been ironed out yet. Seem to start seizing up after running for a half hour or so but turns over easy.
3410 I got back in 1996. Was using it to push dirt last week and wouldn't restart after I stopped to put gas in it. Just may be coil.
How I manage to use both tiller and blade without removing either. I had the end plates made some years ago to move more dirt rather than just let a lot roll off.
I use a bumper jack to hold up tiller when using blade.
I use a toggle setup for holding the blade when using the tiller.
