Spring Tines Hp requirement.

[Joe Boy]

What sort of Hp would I need to pull these on Hanslope clay to level off non inversion cultivation.

VADERSTAD Nza600 6m

 

[Joe Boy]

Would be using them only in the spring.

 

[Farmer Miggins]

used to pull 9m mounted tripleK with JD 3650, winter & spring on Hanslope. Tractor was putting about 140 hp at the PTO though.

We use to use a figure of 2hp per S tine for a similar setup.

 

[Joe Boy]

It has 95 tines plus front levelling boards. I'm worried my 200 Hp T7050 will struggle.

Is there an optimum speed for this type of machine.

 

[spikeislander]

I would think 180 would give them a good tug so your 200 should be ok.

That 2hp use to include a levelling board and an after harrow, but those levelling paddles will require more power I would guess, but if they're adjustable I would recon you should be able to sicken the 7050 or set them that you can fly with it.
Is the 7050 200hp with or without boost?

 

[Brisel]

Eh? I have pulled a set this wide with a Ford 8340 125hp on ploughed & pressed Cotswold brash which is sometimes quite steep. How much you use the levelling boards will determine hp use.

 

[Andrew K]

You will pull them no probs ,Joe.

 

[Joe Boy]

The boost is only for road and pto so 200hp is what I get in the field.

Think I might have a punt on them. Thanks for the replies.

I think you will find the T7050 is only 145 HP at the draw bar 180 on the pto

2wd 3140 used to fly with this (on chalk, but after ploughing) normally on duals, faster than this asthmatic old thing

 

[Brisel]

Running that aircon unit probaly took most of the hp...

 

[Banana Bar]

You will pull them easily but will struggle if you left the straw to be incorporated as they block easily ( I'm on hanslope too)

 

[yellow belly]

on ragdale /hanslope soils when I used spring tines 8210 100hp would pull a 6 m triple k at 10 to 12 km on cultivated land
after burning the straw 30 mm depth made a good seed bed for rape

if you put is in deeper the hp requirement goes up so does the cloddiness of the finish

125Hp+

That "+" should be taken very seriously!
We have an nz-a 600 with 79 tines i believe.
We startet with 120 pto hp in front. We only use it after plough. First pass with any leveling at all, and we're around 7 km/h on level ground. Up hill is just making a mess. It works the soil maybe 3 times more effective at 12 km/h. Now we have 200 pto hp in front and i'd say that's about right with few hills if you are on furrows.
We never used it on stubbles, but i think it will block easily.

I was always told 'send the student spring tineing, and the old boy rolling'
