    Grader bounce and tire pressure...

    When you have a washboard imprint in the road it is very difficult to get rid of. No matter where you have your pressures set at, the machine will still lope a bit when you drive over it. Extreme tire pressures will make it worse. We run 770G Deere's with 17.5 x 25 Michelin snow plus tires. Tire...

    Cutting edges

    We have switched mostly to carbide tipped blades. They are expensive to buy, but with the amount maintinence & the longevity of them makes it worth the cost. We put ours on nearly a year ago and they are still OK and have a straight edge. That includes a brutal winter of plowing snow in...

    770G that locked up drive wheels

    We currently run a pair of 770G s. Have had a similar problem on one of them. It would not only lock up the drive train, but would kill the engine as well. We had to replace the solenoid that releases and applies the park brake. It's kind of in an ugly spot to get at. You need to drop the rear...

    Former Champion operators

    Congrats on the purchase of your grader. I do believe that float position was an option. It consisted of float control valves mounted on the lift cylinders that were activated by a pair of switches in the cab. There is supposed to be a light in the controller that makes it easier to read what...

    New Cat Grader

    Have just looked at the Cat 140 brochure link that Graderfan posted. Cat has sure back tracked from the M series. I was a little disappointed in the torque specs. At 827 lb/ft, it's not bad, but still lacks the sheer "grunt power" of our Deeres. We have a pair of 770Gs,that have a low end...

    Grader Rims----- One Piece Rim VS Three Piece Rim ?????

    We currently run a pair of 770G Deeres, with three piece rims. They seem ok in the warm weather, but when the cold weather hit last winter we went out on morning, (our machines live outside in all weather) and found three flat tires on one machine, and four on the other. It appears that the o...

    Champion 730A -96

    Oil is probably leaking into the engine through the rear crankshaft seal. Check the drain that runs from the clutch housing to the transmission. A damaged drain could cause the clutch housing to over fill, and leak through the crank seal. Usually an overfilled clutch housing will cause some...

    Transmission problem Champion D-740-A

    I stand corrected. I also, have had access to parts books and service manuals for Champion graders, and have never seen a torque converter setup mentioned. Unless a machine could be fitted with a lock-up torque, it would not work very well for grading, as the ground speed would vary with the...

    Transmission problem Champion D-740-A

    To start with,Champion graders do not have torque converters. The only graders with converters, are built by Komatsu. They (Champ) use an oil bath flywheel clutch,and a powershift transmission to provide direct drive. The transmission does provide oil to the clutch. The clutch housing, has a...

    Grader Tires

    I was surprised to see someone mention recaps in one of the above posts. We have 17.5 x 25's on our machines, and rarely ever get enough life out of the sidewalls to recap. We find the Michelins are extremely bad for sidewall cracking. We've also tried Bridgestone, and have had about the same...

    Terex

    The first machine operating job that I had, was on a TC12. That was a little over 40 years ago. The old fellow that owned it had built a bush canopy over the entire machine, with the mounts all on the left side tractor. It was pretty nasty to listen to those two detroits yelling under a canopy...

    Huber Road Maintainer and What to Charge for Road Work

    In Manitoba, the last time I checked the rate book, a 946 Volvo was at $170.00 per hour. There is about a 20hp difference from a 940 to 946,so the gov't rate would be a bit less for the 940.
