I purchased the Toro GrandStand 52" early 2013. It took all season to get accustom to the power, zturn controls. I'm not a pro, just a homeowner w/an acre on a 18-25 degree sloped yard. I've rolled 3 riders on these slopes over the years..and had problems getting up or down a hill (usually down, loss of control), getting too old to walk behind, so went with a machine with guts. Damn, and I did get a machine with guts!! Biggest problems w/the Toro: 1. scalping the hill ridge, scalp rollers are on the 60" not the 52, so over the season kept increasing depth high until I got a good cut height and no scalping. 2. tire scalping when making sharp turns. Divits all over the yard the first month or so. Gotten used to the Y turn to prevent tire scalp. 3. No HITCH. That's a lot of machine and not able to haul wood, or other things. A very smart friend of mine said to place a bucket that would fit in between the two front bars that end with the front caster wheels, and bolt it down. Of course, would have to remove it when mowing but now I may be able to get a little more work out of the machine. 4. No easy access to clean under the deck....either do not mow when grass is damp or you will spend at least an hour on your knees reaching under the deck to pull large globs of grass...Again back to my smart friend, (I have a pressure washer) get a pressure washer adapter used for cleaning out roof gutters, it is the perfect size and angle to get under there and blast off the clumps, also purchased a mirror on an extended rod that angles, and now look under to see the areas that need more blasting. (Again his idea). He helped me put the machine on its back to clean for winter storage, yeap, takes two men. And again, if the grass isn't damp...all I see with it lying on its back is a green stained on the under deck, no clumps anywhere, very effective in removing grass. 4. It is limited on the degree of slope, going up it wants to flip (scary), going down no control (again scary). So the very steep parts of the yard have been landscaped to remove "the Threat", guess I could have weed eated those slopes also, but again looking to decrease the work load as I "wizen" into an older man. :=) When I retire from my full time job, this machine and I will go through this suburb and see if anyone wants their lawn mowed at a reasonable cost. Just to have a little spending $$.
