Who makes a riding lawn mower with very good suspension?

Nobody, it's a tractor not a limo. Ferris makes a zero turn with front suspension but I have never operated one.

Ferris if you have the money for it. Stop hitting those bumps,lol.

toro. they have a front and seat suspension I belive. go to toro.com, and check them out.

2008  10 HP  5560 WATT CRAFTSMAN GENERATOR  B&S MOD. 204412-0147-E1   
RUNS WITH ON /OFF SWITCH AND OIL SENSOR  DISCONNECTED.
ORDERED NEW  OIL SENSOR MODULE  SHOULD GETIN DAY OR TWO.
 
QUESTION   THE OIL SENSOR IS ON TOP OF REAR OF ENGINE  [? IS IT A SPARK GAP TYPE SWITCH ?]
I HESITATE TO REMOVE IT AS I CAN FIND NO INFORMATION ON IT IN ANY WEB SIGHTS IVE VISITED.
IT  EVIDENTLY IS A LONG PIECE SCREWED IN WHAT LOOKS TO BE WHERE A OIL DIP STICK COULD BE.
ANY ONE HAVE PART NO. OR PARTS BREAK DOWN ?? I HAVE A TROY-BUILT THAT HAS THE SAME SETUP.
ALL DIAGRAMS I CAN FIND SHOW OIL SWITCH DOWN ON SIDE OF ENGINE NEAR  OIL FILL PLUG.
