Two concerns involving use of FEL while shredding.
1. In close quarters, like fence intersection or fence corner the loader bucket tends to get in the way, which leads the operator to raise the loader above the fence height, which can cause...
2. a ROLLOVER. Always keep the FEL as low to ground as you can. Especially if you carry front ballast to offset the weight of your shredder. These tractors typically have a wide operating envelope but on a slight incline, with your FEL fully up for obstruction clearance, that heavy bucket will flip you. Even worse with load in bucket. I've had a rear tire lift just climbing out of shallow-angle road ditch with bucket up to clear the far side.
3. BE CAREFUL. Keep Bucket DOWN. Better to use Quik-Detach and drop bucket if possible. However, in unknown territory on flat ground, using loader bucket as junk detector will save the shredder---and tires and undercarraige and nerves.
