Hydraulic drive fert spinner

[R J]

Looking to change fertiliser spreader, is hydraulic drive a advantage ?
Thanks

Certainly more expensive you can regulate the speed better with hyd

 

[wuddy]

You can alter your disc speeds depending on product and width you are spreading, disc speed doesn’t alter when engine revs drop when you hit a hill, no pto shaft to corrode or seize with a I would say hydraulic motors are better sealed than brgs for keeping water fert mix out.

As above, seems daft to use PTO when ample grunt can be delivered hydraulically by a modern tractor's own pump. Disc speed less dependant on engine revs, though modern CVT gearboxes are probably overcoming that.

Conversely, engine speeding up coming downhill less of an issue as well.

Would depend on your tractor?

We've only one with easy to adjust electric spools. Once you have hydraulic flow set can you vary disc speed with control box?

Most of them run on power beyond. Hydraulic is usually more expensive.

Yes especially if you work on steep ground.

I miss mine every time I engage the PTO on the current spreader!!

No idea only one I’ve used was isobus running through a jd screen you just tweaked the elec spool on the screen

I personally don’t think they hold their money aswell second hand

I hate pto shafts with a passion! In the past couple of years with changed both the sprayer and spreader to hydraulic drive models. Easier to connect, no shaft to grease and much safer. Definitely a step forward.

Problem comes with certain tractors that the Hyd/trans oil changes temperature a lot, then the spreader needs a calibration jmhalfwsy through the day...we offer a hyd option on our Kv ones but have never sold one, if the drop point is altered onto the disc, then the fert can be placed right across the full with of the spreader...if your tractors a vario, even better, set the pto speed and do what you want with the fed speed eh!

 

[quattro]

Trouble is when they get older and further down the line
the guy who has it ,has a older tractor with not as good oil flow or the motors are getting warm and doesn’t work aswell as it should

Yes you can give the spreader full flow from tractor and it regulates the disc speed itself

That sounds good then. I imagined it was fully controlled by flow rate from tractor.

The Amazon I run is certainly controlled through the box and I’m sure Kuhn is the same can’t speak for anything else. Run the spool about no 6 on my JD Gives enough flow for the whole speed range of the discs.

 

[KB6930]

The kuhn I had was the same just set the spool about half flow and you could be ticking over or running flat out and you still got the correct disc speed. Even with the vario tractor on a steep hill it still wants to run on going downhill so changes the PTO speed where the hydraulic never changes

 

[Welshlad91]

As long as you have a constant flow of oil to the machine and a decent free return line back to the tractor, the machine can regulate the disc speed to what you set in the box.
Hydraulic drive offers a lot of advantages,
Constant disc speed no matter the engine revs as said above.
Border spreading can be set and adjusted from the cab as you can slow down the one disc so it doesn’t throw it in the hedge. So no border spreading system to set.
Section control is more accurate, as you can adjust disc speed as well as drop point.
Save fuel.
No pto shaft to grease

Full control of disc speed when border spreading, Tractor runs at 1200 rpm , could be on tickover on flat ground! Section control etc the list is endless. Go weigh cell as well

To be fair the hydraulic option on a kv is fairly crap compared to other's as it just replaces the PTO from what I can see . Where others have a motor for each disc so you can do a lot more with it and no need for a border limiter that shatters fert .

If I stay with kv for the next spreader I'll be looking to go hydraulic but if it's not cost effective it'll have to be a pto again

What Type of Kverneland spreader are you running and whats your thoughts ?
