Closing Recommendation
Weigh long-term durability against ease of moving the machine before deciding. The Bull SD76 BS4 Champion digs deeper, carries a bigger bucket, and holds more fuel and hydraulic fluid for long shifts, but it is heavier, has manual steering as a backup rather than hydraulic power steering, and comes with a shorter warranty. The Manitou MBL 745 S is lighter, easier to transport, backed by a longer warranty, and places material more precisely, though it lifts less and holds a smaller shovel. So match the machine to your work: Bull SD76 BS4 Champion for heavy, sustained digging, Manitou MBL 745 S for frequent site moves and precise placement work.
