The rear scraper blades LTA 3000, LTA 5000 and LTA 5000
S were designed to simply and quickly carry out works in terrraces,
construction sites and to provide servicing in your property
roads and tracks, leveling the ground and removing bumps and
depressions in areas in the farming. The large free height of the
frame from the ground allows moving a great amount of earth.
It features reinforced structure, sturdy parts where
mechanical forces concentrate, better weight distribution, and
ensures excellent performance in a wide range of conditions.
The tractor is required to provide dual control of the hydraulic
drive.
The blade features vertical and horizontal angle adjustment.
This instructions manual contains the necessary information
for the best performance of this blade. The operator must carefully
read the entire manual before working with the equipment. Also,
read and understand the safety recommendations.
For any further clarification or in the event of technical
problems that may arise during the service, consult your dealer
