Trailed sprayer , what's good , what's bad

Has your knight got a passive tracking drawbar, I.e. It's a closed circuit system that follows the tractor regardless? We had that on our old one. The JD we have now uses constant pumping from a spool to pressurise the steering rams according to a sensor position in relation to the tractor. It means by flicking a switch you can lock the sprayer straight for transport, and with practice you can steer the sprayer on another toggle switch manually when backing into corners etc.

There have still been plenty of times I wished for that tidy Amazone front and rear mounted setup. But hooking it up would be slow and it's harder to wash out etc etc.


our 2004 hardi commanders had a similar system, worked via a potentionmeter on the tractor drawbar, and an identical one on the kingpin of the sprayer

decent enough, but unstable if you had the oil flow screwed up too much, and it needed re calibrating most weeks, so much so that after a few weeks on it i could do it without even reading the manual

I use a 1999 case/gem ts3000 with tracking drawbar. I haven't seen anything newer that I think would suit us better. I spray some fairly steep fields and I'm convinced a steering axle with hook drawbar would have been on its ribs by now. There are a few places I switch the drawbar off and accept a bit more damage . I just think a headstock to lower arms will push down on one side and lift the other but with more stability than the hook.

A heavier tractor definitely helps. Pushing the sprayer up a hill side can drag the lighter tractors backend downhill . I also run about 500kg on the nose as it stops the front end running wide on turns.

Not the easiest thing to reverse up a tramline and slower in field corners but I wouldn't want to go back to a mounted now. 2 minutes and its kicked off and I'm able to do other jobs
Same here but with a Case/Gem TS2600. Havn't seen much newer with as low a centre of gravity for the hills.

had folks with gem sprayers around here in the past , always had a good name . can I ask what to look for etc , found one with a renson pump on it , you don't tend to see many with that pump on but I do know they fill quick , why do some have these pumps and other diapham pumps ? also it is a non tracking white tank machine without rds , will put that on for a grand.

We have a 2002 knight eu that has been spot on. It has rams on the tracking drawbar so it good you can lock it on the road. If you don't turn sharp it tracs very nicely. Nice sweping turns. It is starting to get old now but it has done a lot of work over 12000ac a year. But will be here are a year or 2 eyet. We will chance it for another knight. Knight eu's are about for your money.
I've just bought a 1999 Knight Anglia with tracking drawbar as described above. Present owner doesn't use it because 'it twitches' when you are going down a straight tram line. Can it not be turned off on the straight or is it incorrectly adjusted?

Tracking drawbar has only played up when there was a pin pulled out of the plug for the steering on the control box and a didn't make contact all the time. I don't alway turn it off on the road.
 
@Robigus As some of our machines are so customisable and we work directly with each customer with the specs that they need before then getting a machine that fits their exact needs, the prices can vary so much that it is impossible really to put a catch all price. We tend to outline with the customer first exactly what they need and draw up our best quote based on that. I appreciate POA can be frustrating for a customer who wants an immediate price and I will look into seeing if we can put a price range on the webpage, the but these will never be able to be closely accurate until we know what each individual customer wants and needs. Often our customers come with a budget in mind and we can remove and add various aspects and customise the machine so that it fits with the budget. If we put too big a range of prices on each one we may be putting off customers who might actually be able to get it cheaper than they think...it's a really difficult one and I take your point fully on board. Thanks for the feedback :)

I was meaning the second hand ones, they must have a value as advertised.

Tracking sprayers mounted on the lift arms put a lot of stress on the booms & carriage due to the pivot point being so far back also a lot more yaw giving 20/400% application.
I don't think tracking sprayers make any difference to overall yield.
