The sun shade 340 may be decoupled and removed from the operator platform 282 by removing the shade mounting hardware.


In use, the user 900 steps onto the sulky 280 and uses the touch sensitive display 234 to start the mower motor 204. The user 900 may engage the rear drive 216 to move the mower 200 and may control the speed of the mower 200 via the touch sensitive display 234. The user 900 may engage the blade drive 208 to cause rotation of the mowing blade 206 to mow the lawn 910. The user 900 may engage the one or more string trimmers 260 to trim along borders and may change the height of the one or more string trimmers 260 by changing the hood elevation angle 304. On sunny days, the user 900 may couple the sun shade 340 to the operator platform 282 for relief from the sun. The user 900 may couple the operator seat 330 to the operator platform 282 if they do not desire to stand while mowing.
