I have narrowed my search down to 2 different machines the grasshopper 428d or the John deere 997. I have demoed several other mowers to include the exmark lazer xs w/31hp and ferris is 4500 28hp cat and am moving on. I would like to hear the pro's and con's of these 2 machines and how they perform side by side if anyone has done so. I'm getting a demo grasshopper this week although it probably won't be the 428d due to lack of availability and all the JD 997 are sold out her in Ct so I wont be able to demo one. I know its going to be a 60" machine just not sure which one to buy. I cut about 3 acres at my house and have about 30 residential and 10 commercial accounts. The mowing conditions are usually rough, wet and the grass is high with some hills.
