I purchased an RZ HD 48" model three days ago and have mowed my lawn twice now. I really like this mower. You can only get a 48" deck on the RZ HD so that saved me from spending more on an RT HD which would be overkill for my 1/2 acre lawn. Even the RZ HD is overkill. It also prevented me from buying the base RZ for $3,999. I think the upgrades on the HD are worth the $1,100 extra. I was initially looking to upgrade from my JD LX277 AWS steer tractor with 48" deck and mulch kit. I was looking at the 500 series JD tractors and even used 700 select series tractors. Then I saw a picture of a Spartan and started thinking about zero turns. I've never been on a zero turn before. I only mow with my tractor and occasionally pull a lawn cart so a zero turn makes more sense. Well after tons of research and driving 160 miles each way I'm a proud new owner. I was initially sucked in by the looks but quickly discovered nobody offers what the RZ HD does for $5,100. That's a lot of money for a homeowner with 1/2 acre but I hate buying cheap stuff and hopefully it will last me a long time. I'll get some mowing pics up after my knee is better but I tested it out on my very wet fescue back yard to see how it would do in worst case conditions. Portions of the flat part of the yard had 1" of standing water. I wasn't removing more than an inch of grass but it cut is very nice and spit it out without clumping. The radials tracked down the grass in the flooded areas but didn't tear anything up. After a good rain all the mud washed away and it looks great. No way I could have mowed in these conditions with my LX277. I found that if I took my and kept the wheels moving I could even circle around trees without tearing things up in the wet. Everything on the RZ is easily accessible and it looks like it will be very simple to maintain. I have the model with the 24hp Kawasaki FR730v. I do all my own maintenance and it should be a breeze compared to my LX277. I only have one real complaint and that is the surface rust that is located at the welds on the frame and deck. I also had some bad rusting on the back right side deck pulley. Not sure if the drain hole was clogged as the other pulleys are rust free. I bought it from a farm supply store so all the machines sit outside and it's been very rainy in Missouri lately. My LX277 is sixteen years old and the welds aren't rusted. So I'm very happy with the performance of my RZ HD. Spartan does need to improve their powder coating process though. I don't really now anything about powder coating but I wouldn't expect the welds to rust the way they do. I'm not the only one. Somebody posted pics in the big thread that looked identical to my issue. My fix for this is a couple hours spent brushing the welds with rust converter. The stuff that turns rust black and can be painted over. Maybe Spartan will send me some touch up paint and a new pulley. Anyway I'll post some cut pics when I have a chance to take some before and after pics. A couple pics attached including the rusted pulley.
