Trailed vs Self Propelled Sprayer

[Brisel]

 

[Alistair Nelson]

That’s the one. What’s the bottom one looks Australian?

 

[Brisel]

Yes. I just did a quick Google Images search for "trailed sprayer swan neck"

 

[Clive]

If someone built one with tank that came up and over the fastrac rear deck I bet it could be made short enough to keep sprayer axle close enough to tractor rear wheels to make single track turns ?

 

[Feldspar]

If you’re thinking the 4ws will mean self prop single track turns with a trailed ? Apparently it won’t ! I investigated this route before we bought our gs60000

I hadn't realised that the back wheel doesn't articulate as much as the front which I guess means it won't track perfectly. Still better than a normal tractor though.

Was mainly looking at them from the comfort point of view.

Bottom one is a Hardi for use behind a Ute. Usually a 79 series Toyota landcruiser.

 

[Richard Smyth]

Just like this.

 

[Brisel]

That ute looks like it knows what's hitched behind it! Any trailer brakes? That's got to be over 6 tonnes...

What are the 2 antenna on the bull bar for? CDMA and GSM aerials?

 

[Richard Smyth]

I’d be surprised if there is brakes. Yeah phone and uhf aerials id imagine.

Pretty sure most of the gooseneck sprayers were 2700 liters but I’m sure there are other sizes. I’ve never seen one but heard about them.

Tyres - check out the load rating on these

 

[faircomment]

Think a normal 650/65 42 has a load rating of 161. I cannot see a load rating from the pics (might just be me being blind?)

Load rating isn’t in the pic - you can look it up though

174 apparently, not sure what that means in real terms but am sure they are very good tyres

Correct me if I’m wrong but Iirc the 4ws fastracs used to have a setting where the front and rear wheel steering turned at the same amount on both axles to start with then once the rear axle hit the stops the front turned a bit more.

So if rear axle had 20 degree of lock as long as front wheels don’t go over 20 degrees it should track true iyswim

I can’t recall the numbers but it means a remarkably low pressure at 55kph when full

I think that is how they still work. Generally to be able to get the boom straightened out / square enough for long enough you need to turn fairly sharp in and out of which would take it beyond what the back wheels can do?

I’m not sure to be honest. But would say 20 degrees on both axles gives a reasonable lock and with the rear wheels turning as well it should keep the sprayer straight for a little longer.

As said I know very little about them.

 

[Chae1]

The idea of the delayed 4ws as i understand it is, when you make a small adjustment when ploughing or in tramline only a small amount of crop is run down.

I thought some self propelleds switched between 2 and 4ws when spraying and not?

Fastrac can be linked to main spray on/off switch to activate/deactivate 4ws too.

How well are guys finding their trailed sprayers follow the tractor tracks?

Knight Trailblazer here and it's not very good at following the tractor tracks. Track width set at 2m (79") and it is still poor to follow even when on row crops.

The Horsch follows perfectly, cant fault it. only the tractor front wheels are outside the track on turns but that can't be avoided
