This invention discloses a bidirectional braking system for a backhoe loader, comprising a gearbox, a loading brake valve, and a brake. The gearbox supplies oil to the loading brake valve and the digging brake valve. Both brake valves are connected to the brake via a selector valve. The backhoe loader has control devices at its two different working ends for controlling whether the two brake valves are open. When the backhoe loader is in loading operation, the selector valve opens the loading brake valve and the brake; when the backhoe loader is in digging operation, the selector valve opens the digging brake valve and the brake. This device enables bidirectional braking of the backhoe loader during both digging and loading operations.

The funnel attachment for a heavy machinery bucket includes a funnel and one or more hydraulic pistons. The funnel may be pivotably coupled to a bucket of a loader.
