Its a Scotts Turf-Vac with 6.5 HP Intec OVC engine. Its John
Deere...supposed to be a good brand! Worked great until recently. Now
it suddenly cuts off when you move the mower. As long as it sits
still, level, it will run fine. If you lift the left wheels off the
ground, or lift it up off the rear wheels, it is fine. But if you tilt
it back so the front wheels come up, or lift up the right wheels, it
stops. Ideas? Every time I take a mower in for repair I can count on
a monimum of $60...so I need to figure this out and fix myself.
