BACKFILLING:

Backfilling is a process where the operator turns the

blade around 180̊⁰ and pushes the product while

backing-up. Be careful not to overstress the Rear

Blade while backfilling, as load forces on the blade

andontheframeincreasewhenbackingup.Tohelp

protect the rear blade from damage, lengthen the

tractor’s center top link until the blade will move

acrossthetopofthegroundwithoutforcingitselfinto

the soil, adjust the offset to be straight behind the

tractor and set the blade angle at 90⁰(perpendicular

tothemainframe).Keeptheloadinthecenterofthe

blade and not on the end of the blade. Don’t ram a

load with the blade and always operate at slow

speeds when backing-up. Be ready to stop

immediatelyifasolidobjectishit.
