Panhandle of Ne. | I currently have a redball 1600 gal w/90ft boom w/duals and really like the sprayer, but it sure knocks down a lot of corn on the second spraying. I was wondering if anyone has sprayed with the wylie pivotracker sprayer that follows the tractor when you turn around? Looks like a nice rig if it works like advertised.

Auxvasse, MO | Get a self propelled sprayer you will like it a lot more. |

I'm not so sure. I did exactly that and went from a pull type sprayer to a Deere 4720. I have problems staying off the row with the 4720. I thought it would be easier than the pull type, but it seems to dogtrack at times.
I'm actually spraying slower than I did with the pull type. I must constantly check the rear view mirror to see how much to lead my steering.
I do get more done since I went from 60' to 90' and I have less sets of wheel tracks so I should be doing less damage in that respect. I can't for the life of me so how the custom operators can go so fast - maybe they're not staying off the row.
I notice on some neighboring fields run by a BTO, that they have some soybeans at 30" and some at 20". They spray the 30" beans with the rows but spray the 20" beans crossways.

West Texas | You should not have that much trouble staying on the row unless row spacing is less then 30".
I used to consistently run 20 mph without running over crops in 34" rows with a JD 4920. A 4920 is a lot harder to keep in the row then a 47x0. Even in ripped ground.
You might need to look into steering problems as in worn or loose components. |

North West IA/western AZ | I run a little Willmar 750 and could not figure what was knocking my corn down (I can only see the front wheels). This is an articulated machine, I thought it would always leave only one track, but it doesn't. That being said, it would do much more damage with duals. I agree with the poster who said to go SP. |

| I run a 4720 in 30" row crops at 20 MPH and haven't had that bad of luck running over the rows. It does take about one load in the spring to get back used to driving the sprayer but after that it is just fine. We have put 6 weights on the front of the machine this year and has appeared to help a lot. Maybe this will help you out. |

Eastern Iowa | Aren't you also on flat ground Dutch? |

West Texas | Some flat and some not so flat. A lot of our stuff is gently rolling with a few steep hill sides. |

SCMN | Ted, I saw that same BTO doing the same thing on their 20" beans last year, I just figured they didn't have enough GPS accuracy to come back on the rows with the sprayer, I assumer they are just running SF2 or SF1. When they spray across the rows they can use either signal and just hit the button. They are plating a bunch of canning crops and some wheat this year up by me. It's weird, they rent 240 across the road from some of ours and they came out and planted about 20 acres of field corn and then 20 acres of beans later, with a 12 row planter!!! Then they planted the rest to sweet corn this week I was told. I wonder what's going on with that?

Southern MN | Crop insurance. I think you have to have 5 acres of a crop in order for it to provide your proven yield for the entire field. Probably had a low average, so they poured on the fertilizer on those 20 acre parts and planted it. Get good yields and raise the aph on the whole farm. |

central nebraska | Think about putting 1600 gallons on four wheels(self propelled) compared to a pull type if running duals on the tractor drive wheels the load is on 8 wheels. I have noticed neighbor's fields that are being sprayed with a self propelled the tracks that they leave are deep and you can see them all year long, especially when they spray across the rows on the ends. We have a 1200 gallon 80 ft boom, I want to go to a 1600 gallon 100ft boom I don't think a self propelled machine would be able to keep up with me if I go this way. The just can't carry the extra gallons. I would not switch to a self propelled. Another way to look at it is, $45,000 on the high side for a very good pull type. You can now spend $130,000 on a tractor or spend the same $175,000 for a self propelled. If you go with a pull type, after spraying season is over unhook the tractor and use it, or park the self propelled and wait for next season. I think you need to spray in excess of 20,000 acres a year to make a self propelled pay for itself. Just my thought on it. |

I'm not saying that I disagree with your speed but I am limited to about 8 MPH. Even at this speed, spraying is more physically demanding than I care for. The ability to stay off the rows is better in the soybeans which have been rolled versus the corn which was sprayed earlier.
One of the local custom operators agreed with me and said that the beans would be easier at least on the first pass. For second pass, he said the customers will complain that it appears they were sprayed by a drunken sailor. He said he just blows it off and figures if they can do it better themselves then go ahead. I guess he's probably right as I was one who complained about the job the custom guys did. Now I know it's not that easy.
The Tech was out yesterday investigating some charging problems - another story in its own. He adjusted the toe in/out a bit. While he had his test rod out (a homemade device with a piece of PCV pipe inserted in another with a thumbscrew), we checked the rear tires. These tires are worn quite badly - all on the right side. Anyway using the test rod showed that the distance between the front of the rear tires agreed closely to the distance between the back of the rear tires. However, when he did a diagonal check, the distance from the front of the rear left tire to the back of the rear right tire was less than the other diagonal. This corresponds to the dogtracking that I have observed.
Changing the alignment of the rear end could possibly be done with some tweaking of the adjusting shims. Since I do not need to adjust the wheel tread setting, this might be a possiblility but I am told this is a major task.
He also mentioned that another customer had compained that he observed more dogtracking this year than in other years with the same machine. This customer felt that he when he went to a full stack of 12 Deere weights that the situation improved considerably.
The Tech mentioned that my 4720 is really an evolution of the original 4700 that was designed for a 60' boom and a 700 gallon tank. He speculated that the balance has been changed considerably when the change to a 90' boom and the large tank came along. |
