How to Choose the Right Backhoe Attachments
The right backhoe depends on your machine, digging requirements, and the type of work you plan to handle. Before buying, compare tractor horsepower, hitch category, digging depth, bucket width, attachment weight, and mounting system rather than choosing only by backhoe size. Farmry’s Backhoe Dimensions Guide provides additional sizing guidance for compact and utility tractor owners.
Match the Backhoe to Your Tractor HP
Start by matching the backhoe to your tractor’s horsepower and hitch category. Farmry models range from the compact BH600 series for 18–35 HP tractors to BH920 models designed for tractors up to 120 HP, while BH700 and BH820 models cover common compact and utility tractor ranges. If you are unsure whether horsepower alone is enough, see Farmry’s Tractor HP for Backhoe Guide for additional compatibility factors such as tractor weight, stability, PTO, and digging requirements.
Choose the Right Digging Depth
Digging depth determines how well a backhoe fits jobs such as drainage lines, utility trenches, landscaping, and deeper excavation. Farmry’s tractor backhoe lineup includes models around 6 ft, 7 ft, 8 ft, and 9 ft digging classes, allowing buyers to match reach to the work they actually perform instead of automatically choosing the largest attachment. For more detailed measurements and tractor-fit considerations, compare the models in the Backhoe Dimensions Guide.
Match the Heavy Duty Bucket Size to Your Job
Bucket width affects trench width, digging speed, and how much material is moved with each pass. Farmry backhoes are available with common 12-inch, 15-inch, and 18-inch buckets, with narrower buckets suited to utility trenches and wider options better for drainage and moving more soil. The Backhoe Bucket Width Guide explains how to choose between these sizes based on trench width, soil conditions, and workload.
Check PTO and Hitch Compatibility
For a tractor-mounted backhoe, confirm the hitch category and PTO setup before ordering. Farmry’s BH600 models use Cat 1, BH700 and BH820 tractor models support Cat 1 & 2, and BH920 tractor models use Cat 2, so the correct model depends on more than horsepower alone, while skid steer hydraulic setups should also be checked for hydraulic flow requirements when confirming attachment compatibility. Skid steer owners should instead compare Farmry’s hydraulic skid steer backhoe attachments, which use a different mounting and hydraulic setup, and some setups also use couplers for faster attachment changes.
Compare Farmry Backhoe Attachment Sizes
Farmry offers backhoe attachments for compact tractors, utility tractors, and skid steers, and while common backhoe attachments include augers, buckets, and grapples, the table below focuses on Farmry models with different digging depths, bucket sizes, horsepower ranges, and hitch configurations. Smaller BH600 and BH700 models are suited to lighter property-maintenance and trenching work, while BH820 and BH920 models provide additional reach for larger tractors and more demanding digging jobs. Compare the model specifications below to find the backhoe that best matches your machine and workload.
What Material Handling Can You Do With a Backhoe Attachment?
A backhoe attachment can handle many common farm and rural property jobs, including digging utility trenches, installing drainage, cleaning ditches, planting trees, landscaping, and light excavation. It can be a practical option for owners who already have a compatible tractor or skid steer and do not need a dedicated excavator for every project. For larger digging jobs, Farmry’s Backhoe vs Excavator Guide explains when an attachment makes sense and when a dedicated excavator may be the better choice.
PTO Backhoe Compatibility & Setup Guide
PTO Requirements
PTO Requirements
The tractor must have:
- 1-3/8", 6-spline PTO shaft
- Fixed operating speed of 540 RPM
The tractor cannot operate at any speed other than 540 rpm.
It is not recommended that tractors with a variable speed PTO be used with the backhoe. Operating at speeds higher than 540 rpm can overspeed the pump and cause early failures.
PTO Clearance Requirement
PTO Clearance Requirement
Ensure there is sufficient clearance around your tractor’s PTO shaft:
Minimum clearance required: 7-3/4 inches
Insufficient space may prevent proper installation.
PTO Pump Compatibility Check
PTO Pump Compatibility Check
The PTO pump requires the following installation space:
160 × 224 mm (6.3 × 8.8 inches)
If any tractor components fall within this area:
The PTO pump cannot be installed
PTO Extender Requirement
PTO Extender Requirement
For models including:
- BH600 / BH600 PRO
- BH700 / BH700 PRO
- BH820 / BH820 PRO
- BH920 / BH920 PRO
Installation interference may occur between the PTO pump and tractor, preventing full engagement with the PTO shaft.
A PTO extender is required if:
- Clearance is insufficient
- PTO pump cannot fully engage
- Installation interference occurs
The extender ensures proper alignment and safe operation.
It can be purchased through Farmry or most agricultural equipment dealers.
Installation Checklist
Installation Checklist
Before installing your PTO backhoe attachment:
- Ensure mounting alignment is correct
- Check all hydraulic lines
- Confirm PTO connection is secure
- Verify no interference in rear mounting area
- Ensure all components are properly installed
Proper setup ensures safe operation and reduces long-term maintenance issues.
FAQs
What is a PTO backhoe attachment?
What is a PTO backhoe attachment?
A PTO backhoe attachment is a digging attachment powered by the tractor’s PTO shaft. It uses a dedicated pump to generate hydraulic power, allowing it to perform trenching, digging, and excavation tasks independently from the tractor’s internal hydraulic system.
Why choose a PTO backhoe instead of a hydraulic backhoe?
Why choose a PTO backhoe instead of a hydraulic backhoe?
A PTO backhoe is ideal when a tractor’s hydraulic system is not strong enough to support consistent digging performance. By using PTO-driven power, it provides more stable output and is often a more cost effective solution for property owners and contractors.
What PTO requirements are needed for a backhoe attachment?
What PTO requirements are needed for a backhoe attachment?
Most PTO backhoes require a standard PTO shaft setup and a fixed operating speed. Ensuring your tractor meets these requirements is critical for safe and reliable operation.
Refer to the technical guide below for exact PTO specifications.
Is a PTO backhoe powerful enough for trenching and excavation?
Is a PTO backhoe powerful enough for trenching and excavation?
Yes, a properly matched PTO backhoe attachment can handle trench work, drainage installation, and light to medium excavation tasks effectively. Performance depends on the model, tractor compatibility, and digging depth.
How do I know if a PTO backhoe will fit my tractor?
How do I know if a PTO backhoe will fit my tractor?
Fitment depends on PTO compatibility, mounting space, and rear clearance. Some installations may require additional adjustments to ensure proper connection.
