- Controls are located on the tower, which allows easier access to the operator station
- A curved power boom gives you a better view of the digging area
- Seat-locking mechanism keeps the seat out of the way when the backhoe is not in use
- Sturdy grab handle on the control tower ensures ease of entering and exiting the tractor
Features may include:
Backhoe performanceTo ensure optimum performance, the tractor's hydraulic flow and increased system pressure are matched with the backhoe's system enhancing the digging force and overall performance.
This backhoe has several features that make it best in class when put on the proper tractors.
Key include:- Valve spools have machined-metering grooves to allow smooth operation and precise control of several functions
- Improved feel and feathering capabilities
- Strong subframe to ensure the tractor frame can handle the forces created from digging and transporting
- Buckets are state of the art, designed for optimum productivity; Buckets available in 9-, 12-, 16-, 20-, 24-, and 18- heavy-duty
- Custom thumb allows movement of large and/or uneven shaped objects
- Mid-mount mower compatibility
- 3-point hitch arms can remain on the tractor when backhoe is installed
The backhoe's mainframe fits into rear mounting brackets installed on the tractor. This provides the following important features:
- Vertical or side-to-side movement is virtually eliminated, providing more stability. The design of the mainframe also positions the entire backhoe close to the tractor. Operators are also able to benefit from the total weight transfer between the backhoe stabilizers and loader bucket.
- The tractor chassis is protected because the mainframe integrates the tractor and backhoe combination together as one.
- Once the mounting frame is installed, attaching and detaching is quick and easy.
- Review the operator’s manual for detailed procedure.
- Back up the tractor to backhoe. Turn off the tractor and engage parking brake.
- Install lift rod to lower draft arms on tractor. Retract drawbar to storage position and remove upper link from tractor three-point.
- Release the parking brake.
- Back tractor into backhoe, engaging lift rod into slots on mainframe. Raise backhoe to full height using the tractor-hitch control lever.
- Turn off the tractor and engage parking brake.
- Secure backhoe to the tractor using L-pins and lynchpins on backhoe.
- Lower the draft arm control lever to relieve pressure in the circuit.
- Connect the hydraulics.
- Make sure the draft arm control lever remains in lowered position.
- Review the operator’s manual for detailed procedure. Select a firm, level site to remove the backhoe and engage the parking brake.
- Lower boom and install lock pin in park position on backhoe boom.
- Position the backhoe’s bucket so the teeth are parallel to ground.
- Turn off the tractor.
- Disconnect the hydraulics and reconnect the tractor power beyond hydraulics.
- Start the tractor then raise backhoe to full height using tractor-hitch control lever.
- Remove L-pins and lynchpins securing backhoe to tractor.
- Lower backhoe to ground. Make sure lift rod weldment is released from slots in mainframe.
