PRODUCT INFORMATION

This backhoe digger is for those who need extra power and reach in digging work.

• 

Backhoe digger for tractors over 70 hp

• 

Mounted on 3-point linkage

• 

Digs 285 cm deep, bucket width 50 cm

A backhoe digger for most digging jobs such as clearing ditches, laying hoses and cables, grading 

courtyards and drainage maintenance.

The digger arm has a reach of 460 cm and the bent steel boom provides a good movement pattern. 

The backhoe digger digs 285 cm deep, with a powerful serrated digger bucket 50 cm in width.

The backhoe digger is controlled from the tractor cab with a 2-lever valve block, with separate levers 

for the stabilisers and additional hydraulic outlet. If you prefer to control operations from the digger, 

an operator seat is available as an accessory.

The hydraulic stabilisers are manually adjustable laterally, to adapt the rig for enclosed spaces or 

maximum lateral stability. The backhoe digger has its own hydraulic system with integrated hydrau-

lic oil tank and hydraulic pump with gearbox mounted on the tractor's PTO drive shaft, giving the oil 

flow the digger needs while the tractor can run at a low engine speed, yielding good fuel economy. 

Accessories: narrow bucket, ditch bucket and grading bucket, both fixed and tiltable.
