Mower related:
Just remember with a mower that the wider the deck the higher probability to scalp certain spots. A mower just like a vacuum needs to be chosen based on territory. A Kirby isn't the best choice for a house of all laminate flooring. A large tractor with an 8' mowing deck would be a very poor choice for a hilly area.
A Bush Hog is more suited for rough terrain in fields that you want kept reasonably trimmed but it's not be the nicest result. A Finish mower on a tractor will leave a better cut. A Scag will leave a far better cut than either of those! With Scag there is price, but the cut is gorgeous!! Their Advantage and Velocity cutting duck styles offer a lot of vacuum action and adjustable bevels to pull the blades straight up for a smooth even cut and end finish. The powerful discharge allows for a more even distribution of clippings so the end finish is just gorgeous. Then of course they have an extremely high durability ratings. Thick gauge steel and metal instead of plastic in the places you want them etc. There is no cheap commercial duty machine which is what the Scag is.
A Scag is completely different ball park of quality over a Toro TimeCutter residential series, Husqvarna, Craftsman Professional, etc! The cut is far better than John Deeres!
Again it's all based on your terrain, budget and if it's just your property or you have a business, how fast you're looking to be done and how nice of a finish you are seeking!
A Zero Turn walk behind or Zero Turn rider can go row by row with no time wasted taking your mower out to China and making a huge circle further marking up your lawn to eventually refind your next row!! That's a savings of fuel, blade sharpness, time, and a better overall finish! Also Zero turn walk behinds and riders have the option for bagging, getting a mulch kit or discharging.
For entertainment just check out how tall this lawn is and how good it looks after just 1 pass with this Scag zero turn. Granted you know you'll definitely have to double cut or even quadruple cut this property with any lawn this height with certain mowers. But look how good it gets it with just 1 pass!!!
