New JD672G Grader

[Cat 140M AWD]

Yeah ik where the lights are at on the top of the cab I operate a 2011 772GP to me the lights on the back of the cab are to far away to see what your doing behind you I like having 2 work lights on the very back of machine that I leave on while grading or plowing snow I just turn them off when I run down the highway

I've noticed during cool weather when I first start up the machine "steams" a lot out of the exhaust for 15 minutes. Then after this point for another 15 minutes it struggles to develop power. It won't reach governed speed in high gear on flat ground. Is this normal? Do I need to expect to thoroughly warm the machine before starting out?

It is very common now to see FT4 Deere machines letting steam out the exhaust when the engine starts up on a cold morning. I am not sure about the motor grader but some of the other Deere machines (dozers in particular) now have restricted movement and limited engine rpm until Engine/Hydraulic/Transmission temperatures reaches a certain threshold.

I was visiting with a friend who has a new Kubota CTL. He said a light flashes on the dash and it won't rev up for a couple minutes when he first starts it. Says it will do that in anything cooler than around 40F.

I'm not a crank up and go guy on a cold engine. But I don't want to have to warm the machine 30 minutes either. Especially in 50F weather.

 

[mg2361]

Definitely shouldn't have to at 50 degrees. Any codes?

 

[ovrszd]

No codes.

 

[mg2361]

Did it run OK when warmed up? Did the steam stop when warmed up?

 

[ovrszd]

Yes on both questions. Steam stops after 5-10 minutes. Regains power after 15-20 minutes. All depending on what the machine is doing.

Makes me wonder if a temperature sensor is having what we call an "in range" failure? I don't recall how many temperature sensors you can read through the monitor, but it might be worth looking at. With machine cold, key on engine off, look at temperature sensors. Maybe a trans or hyd temp is reading 0 degrees while the rest are at 50 degrees?

 

[ovrszd]

Good stuff. I'll check that in a day or two. Aren't running the machine now due to weather. Thanks for the tips!!!

Pushed snow yesterday. Totally forgot to check the various temps before I started the machine. I'll try to remember that next time.

Was my first time working at night with the LED lights. Absolutely awesome. Seemed to be less eye strain. Definitely can see the blade just as well as daylight. Great visibility all around the machine.

Was also first time with 6wd. We had gotten a thin layer of ice, then 3" of snow, then 1/2" of ice on top. I didn't chain up. Ran 6wd all day. One section of my roads has pretty steep hills. The worst one is at a T intersection. I wanted to scrape all the ice off that one. Had to cheat and put right side tires on the grass bank to get enough traction to get to the top the first pass. Once I had a swath cleaned for one side I was good. Loved running without chains!!!!

Ran the front tire speed equal to the rears. Doesn't seem to take any more HP engaged or disengaged.

I think I'll be able to do all light snows, 6" or less without chains. Drifts or heavy snow would still require chains though.

I've saw pics here on HEF of all wheel drive graders with snow tread tires on. I never fully understood the value of those. Now I do. They would add even more traction without the addition of chains.

With the snow tires and 6 wheel drive only time you need chains is when you get really bad ice I haven’t put chains on a grader in 10 yrs and don’t miss having to either

Got another snow. Including a LOT of ice....

Thin layer of ice. Then 5" of heavy, wet snow. Then 3" of dry snow. It sucked. I chained the rear four. Had to run very slow (7-9 mph) to prevent lope. Took 16hrs to take off the snow. Then the next night went back and cut the bottom layer of ice the best I could.

Some steep hills I had to raise the blade a pinch to not spin out. On those hills I wish I'd had the front chained.

I've still got about six hours of work left. I'll go to bed around 8 p.m., get up around 2 a.m. and finish.

Started at midnight Thursday night, worked til 4 p.m. Friday. Went to bed at 7 p.m. and got up at 2 a.m. Saturday morning and worked til 3 p.m.

I try to work at night when I can to avoid traffic. I had to wait until midnight Thursday for it to quit snowing.....

Here's some not so good pics I took this morning. Love the LED lights.

 

[Cat 140M AWD]

Wow the LED lights are amazing my township is going to be updating there machine there looking at a brand new 772GP I’m definitely going to tell them to get the LED lights snow on top of ice is never any fun.

 

[ovrszd]

Yeah the lights are a valued option if you do a lot of night work. As I said before, I prefer to work at night. You can see traffic coming. I'm very rural and can push snow all night without seeing a vehicle. About daylight that changes. Lost track of how many times I've had vehicles drive into a large drift behind me. Flip it reverse to back up and get another run, glance in the mirrors and there's a car sitting behind me!!!!!! Where the H do they think they are going?? The road is drifted full ahead of me!!!! People...…

I've ran this township 30 years. This snow was the worst I've pushed in regards to traction and loping. I even stopped by my home shop and added 10psi of air to the tires hoping that would change it but not.

It's so foggy this morning that visibility is almost non existent so I didn't go out. I'll wait for it to burn off a little.

If you get a new machine start a thread!!!

You don't run a wing or one way on the front? I miss plowing with my grader. This back and forth with a loader gets hard on the neck. Newfoundland just got 50 inches in one storm last week. Lots of pushing there

We have a hydraulic angle blade that goes on the front scarifier beam. Haven't used it for many years. It uses steel wheels for shoes. If the gravel roads aren't frozen solid it just digs in.

We also have a V-plow that goes on the front as well as a wing that fastens to the moldboard. If we get a windy storm both get used.

it always amazed me that you guys to the south don’t have wings but then again your snow never last long like ours does up here we’re normally solid snow cover from December to late March we have v plows and one ways and wings on every grader up here.

I knew you had that wing on your old grader, wasn't sure if your new one had one or not. I like a front plow for wide turns and clean up at dead ends with no cul-de-sac.

We have a V, but the trees are growing up around it now. Mostly use a one way on front now. She came with 6 new Michelin winter sneakers that we only used 2 winters. I'm in need of 4 new rears, so I suspect they'll pop the winters on and use them year round. I wish they would take some winter plowing with the grader, but government and municipality don't pay much, so better to sit than work for nothing
