I am seriously thinking of going on my own after working many years for a national lawn care company. We use Perma green magnums and ultras and I am familiar with the mechanical problems they will get with very heavy use.. I am wondering about the LT Rich line and if anyone has had them for several years and are there any expensive fixes. I am not mechanically inclined at all so it would mean down time and money spent for someone else to fix. I am interested in the Jr model as this will fit through most gates I believe..but it is REAR WHEEL DRIVE and I know our perma greens aren't strong enough to go up many hills..or they spin out...so I have to step off the back so they can make it up...but with the Rich models this would only take weight off the drive wheel. Any experience in this? Thank you.
