The World's Largest Hydrostatic Bulldozer Working

This is the prototype of the 70 tonne class Liebherr PR776 dozer. It is the largest dozer available yet with a hydrostatic drive system. It is not the largest dozer manufactured. That would be the D575A from Komatsu.

Great drone flying, very smooth.

I’d love a go on this machine. We run Liebherr dozers & recently saw quite a few of these waiting delivery from the Liebherr factory in Austria. While we were there, we were treated to a go on the new 736 Generation 8 machine, which is fantastic & an improved version of the gen 6 version. Would love to see a video on the gen 8 if you can find one working in the UK.

I saw this machine at Vegas Minexpo a few years back. It was impressive.

[@carlosescobar6973]

Love this machine

[@bladerunner6354]

I got on older lieber excavator as i always heard how smooth controls were. No lie there, I had to get use to it being so smooth and touch sensitive to behavior of components.

[@diggermitch1]

in what size it to a cat a d-9 or a d-10 and how many hours do they have on it and have they had any problems with the hydrostatic drive yet

Happy new year

Great bulldozer, but isn't it more efficient to use a scraper for removing long stretches of soil like this?

[@adolfadolfvich3253]

Liebherr?

I’d like to try this machine. Being hydrostatic would offer many benefits. Being able to be high idle constantly would offer stronger hydraulics, turning, and control overall. A downfall would be increased fuel consumption vs conventional trans dozer like a d10.
