I bought a walker and sold it w/in 2 months b/c I THINK they suck. And here are the top ten reasons why you SHOULD NOT buy one. 1. Mowers cannot hold a hill even a very SLIGHT incline!! 2. Tires cannot go up a slight wet incline. 3. Yellow paint chips easily and mower loses its value quickly. 4. The machine is fragile and you would not want to even touch rough terrain w/ it. 5. The hydros are prone to go out. 6. Engines last about half as long as engines on midmounts. 7. Ground speed is low. 8. Have fun changing deck height w/ four pins. 9. Take up a lot of trailer space. 10. Mower basically cannot mow wet grass - clogs, tires have no traction. I bought a walk-behind and lost $800 on my Walker. If you mow commercially I don't know how you can get anything done w/ those things. I could not cut 20 yards a day w/ a Walker like I can w/ my chopper. I did not even save any trim time w/ my Walker. Even the smaller yards, my chopper was quicker. No more yellow paint for me!!
