Kubota BH77 Backhoe Attachment Assembly Instruction

The Kubota BH77 Assembly Instruction Backhoe Attachment is the small backhoe you hang off the back of a compact tractor for trenching, tile repairs, and general farm digging. The Kubota BH77 Assembly Instruction parts manual is what parts counters and field mechanics grab when a pin’s egged out, a cylinder’s leaking, or a bracket’s bent and you need to see how it all goes together. People usually use this kind of parts manual to figure out exactly which piece failed, how it fits in the boom/dipper/subframe stack, and what to order before the machine sits during planting or harvest.

What this manual helps you do

• Identify every component in the BH77 backhoe attachment using exploded diagrams of the boom, dipper, bucket linkage, subframe, and related hardware.
• Locate the correct Kubota OEM part number for pins, bushings, cylinders, hoses, brackets, and hardware so you can order the right pieces once, not twice.
• Look up quantity-per-machine for seals, o-rings, bolts, and nuts so you don’t get halfway through a rebuild and realize you’re short.
• Cross-reference older Kubota part numbers to updated superseded numbers shown in the parts listings when Kubota has revised a component.
• Verify that what’s in your hand matches what’s on the BH77 Assembly Instruction parts manual diagram before you tear deeper into the attachment.

Who this is for

This is aimed at an independent ag mechanic, farm owner-operator, Kubota dealer parts staff, or anyone maintaining a BH77 backhoe in a small fleet. If you’re looking for torque specs, hydraulic test procedures, or step‑by‑step repair instructions, you need the Kubota Workshop/Service Manual instead, not this parts catalog.

Bottom line: If your main goal is to identify and order the correct Kubota BH77 backhoe attachment parts with clear diagrams, this is the right manual; if you need repair procedures, keep looking for the service manual instead.
