I own and operate a 130G and have also operated 120G's,12G's and 140G's.I've had my 130G just over two years.It has rear rippers and front pushblock and weighs in at 15,500 kg.I use it for road construction,maintenance,farm driveways,fence lines and fire breaks.It's been good as my first machine as an owner operator..My only real complaint is that it's a little light on the front end and the 3304 does lack that low end grunt the 12G and 140G have with the 3306,but the grader does everything I ask of it.My Dad has a 2012 John Deere 670G and we worked together for a week just before Christmas doing maintenance grading..The 130G is 28 years old and has about 15,000 hours on the clock and suprised us both as she held it's own and kept up with the 670G.
I brought the 130G as it was what was available at the time.If I had the choice between a 140G and 130G now yeah I'd go 140G but I certainly wouldn't dismiss the 130G.
