Trailed vs Self Propelled Sprayer

[Fraserb]

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.

What steering system is on it, we've had two mechanical tracking drawbars and now onto a steering axle, with a bit of setting up all of them work pretty well, you can confuse the axle by doing a tight turn one way then the other as it can't keep up, but other than that its fine.

It's a steering axle. Machine is only a year old. Must ring Knight and see what they say.

For those running Horsch sprayers on a single set of wheels all year, what wheels are you using and what is the lowest pressure you can run at. I can find a Mitas VF580/85R42. Would ideally like a tall 600, but there doesn't seem to be a VF option.

Also, for those such as @Tom H, I have been advised that having the boom control with 5 sensors and articulation / levelling part way down the boom is unnecessary at 36m on Cambridgeshire fields. Would you agree?

Personally. I would still have it. But if you are Fen flat, I could see where they are coming from.

This is a bit of an ask, but would anyone who has recently bought a Horsch mind checking over the quote that I have? For rigour and due diligence I need to confirm the numbers I have are competitive.

My Chafer Sentry will track perfectly at anything less than 75% lock on the tractor. The long wheelbase of the sprayer means the rear axle won't turn tight enough. Have you tried adjusting the stops?

I guess you are on steering axle rather than drawbar? Mine is on drawbar and you can alter delay sensitivity etc to get it spot on.

We had to tweak a setting in the box on our team to get it spot on, changed the tractor and although the measurements were very close on the new one I had to alter the setting slightly, that was a long way of saying yeah phone them, it'll can be altered.

Some have flow restrictors to alter the speed of turning so they follow the tractor better. The flow rates need to be different each way due to the uneven volumes of oil each side of the ram head (the displacement of the rod).

These boys are making a tidy job with fastracs that are not 4ws, but they’ve set the wheels out looks to at least 80 inch centres.

Yes we've adjusted the stops to the optimum.

Anyone looking for a top spec trailer Horsch would have to go a long way to find one better than this. Only sprayed 800 ha.

I really wish I hadn’t seen that MC, your going to get me in trouble now!! [emoji6]

Belongs to a good mate of mine only for sale due to a big change in policy. It's on a cereal only farm in Cambs and never even seen a SU herbicide.

Great shame it's not a 36m boom. I did ask about converting and apparently it's quite expensive.

going organic ? !

why would you run such a machine on a tractor with tiny 30" wheels on it when you can run one on 42's ?

They look like 34" rims to me.

Why would you run such a machine on a tractor with a cab placed over a rigid axle (even if they are on 42" rims) when you can put it behind a fully suspended tractor with a even more comfortable centrally mounted cab?

34 is still a lot smaller than 42 and not 710 wide either - you want as much rubber under a sprayer as possible, especially a trailed one

I won't start on reliability either being and ex Fastrac owner although Im sure they (can only have) got much better these days !

If it’s the same one I looked at there going to 36m and it was going to cost a lot or widen the booms
