Bought a Hustler Raptor SD 4 years ago. Love it! Had one issue last year though. The bracket under the rear bottom between the hydro motors was the old flimsy style. It broke. Hustler gave me a little run around about covering the part, but a local dealer was able to get the part on warranty and it cost me $52 in labor to have it replaced. Since then, not one problem.
Anyway, since people are talking about string trimmers...I literally just sat down from using my Ego 56v trimmer for the first time (I bought the kit with the carbon fiber shaft model, 2.5AH battery and charger for $229 from HomeDespot). I'm quite impressed so far. The power is amazing, puts my gasser to shame. The battery life isn't as long as I thought it would be based on reviews, but it is only the 2.5AH battery. Admittedly, this is the first trim of the year and the grass was extra thick. I think if I buy the 5AH battery then I'll have enough juice to do everything in one go. One feature it has that I absolutely love is the power string loading feature. Just cut a 13 foot length of string, push it through the eyelets until it's even on both sides, then press the button down by the head and it power winds the string onto the spool. No more hand cranking it or removing the head and spool to manually wind the string on and then get it all snapped back together. It works extremely well. It's also nice not having a 2-stroke engine screaming in your ear either.
