Looking for some help.i need to replace some scalloped disc s on the harrow.the harrow is a souchu et pinet and the disc dimensions are 580 or so diameter and a square hole of 1 and1/4.i can find a parimeter smooth in the right size but not a scalloped

Try Murphys in Littleton Tipperary. Got sorted with something similar, only a touch smaller last summer. May have to be ordered in.

Do you want to bring them in yourself? Try agri-linc, they have a square bearing anyway.

Try sending Dawg a PM.

Talking to a lad today that does scrap n he was saying scrap metal prices are as high now as he can ever remember. Might be no harm if lads have a few yokes covered in briars to poke them out.

Before the nettles get going for another season hey.

ginger22 · 03-04-2022 09:39AM

The Mahle is a high speed geared 4.2 Kw. We do them for 180 plus vat.

should be a handy tool around the place this year

For the locking pin eye of euro brackets, should there be an edge for the loader headstock to push up against, so the locking pins don't take any strain? I noticed some brackets do (like in photo) and some don't.

Yeah there usually is

For the mechanically minded on here, the above is a photo of the chains and sprockets driving the mixer and auger in a turf hopper. I need to increase the speed of the auger to push out turf quicker to suit the lowest available speed in my tractor. Does the sprocket highlighted, the first one off the pto and gearbox need to be replaced with one with less or more teeth to speed up the auger? The auger is driven by the sprocket at the bottom.

DBK1 · 26-04-2022 01:03AM

It would need to have more teeth.

Basically the more teeth the “driving” sprocket has, the more the chain moves for every rotation of it, so therefore the more the “driven” sprocket will move thus speeding up your auger.

How much more speed do you think you need?

From trying to count in the picture it looks like a 32 tooth sprocket driving a 42 tooth. So for every 1 rotation of the highlighted sprocket the auger is only doing three quarters of a rotation. Increasing the highlighted sprocket to a 42 tooth, the same as the auger sprocket, will bring the ratio to 1:1. That would be increasing the auger speed by almost one third more than the current speed.

tellmeabit · 26-04-2022 08:40AM

Or decrease the number on the bottom sprocket?

dzer2 · 26-04-2022 09:32AM

Increasing the size of the drive sprocket will increase the speed of the auger and mixer together. Also it will increase the pressure and wear on the bearings.

It will increase the speed of the auger also but because there is such a size difference in the sprockets on the mixer it won’t be as big an increase.

For we assume the highlighted sprocket is turning at 50rpm and the sprockets are a 32 and 42 tooth, then currently the bottom auger shaft is turning at 38.1 rpm. At a guess it looks like maybe an 18 tooth sprocket on this shaft driving a 76 tooth on the mixer so the mixer would be currently spinning at 9rpm.

If the auger sprocket is now changed to a 42 tooth and everything else remains the same, the highlighted sprocket is still doing 50 rpm, the auger will now increase to 50rpm also and the mixer will be increased to 11.8rpm.

So the extra 12rpm on the auger only gives an extra 2.8rpm on the mixer.

@Gudstock if you can check if my sprocket sizes are correct and tell us what you’re trying to achieve with speeds I’m sure we’ll get you sorted!

I need to increase the speed of the auger to push out turf quicker to suit the lowest available speed in my tractor.

Is there any chance it's a 1000RPM gearbox on the hopper being driven at 540RPM?

Did this hopper spread turf at an adequate speed before?

I'm not sure how big of a benefit the speed increase of the lower auger will be towards being able to increase forward speed significantly.

Is wear visible on the auger flights?

Odelay · 26-04-2022 12:58PM

You’d be surprised the difference 5-10% more teeth can make. I’ve sped up machines that way and rarely an issue.

Never been asked to slow anything down for some reason..

I have said D max.

I tow with it regularly. Personally I find it fine. It's geared quite low. So lots of torque in the lower gears. I'd find going up a hill with any sort of a load you would need to drop back a couple of gears alright. Towing about 1.5 tonne I'd average 9.5km per litre. Regular mixed driving without trailer about 11.5 litres to 12

AckwelFoley · 05-05-2022 01:42PM

@funkey_monkey if you have allt of heavy towing to do regularly the hilux is probably the best option for sure. I think the 2.8 has 40bhp more than the Dmax. The dmax suits me as I use it every day as a car and then to tow 1.5 tonne long distance every so often. I could use something smaller but I wanted specifically the size. She doesn't get pushed around the road at all and you'd hardly notice the weight of the trailer. But getting up into regular 3.5 tonne loads is a different kettle of fish for sure

Anyone have a cheap shear grab for sale?

Looking for a pair of short strong rams, so the rest really isn't important.

Dozer1 · 13-05-2022 10:57PM

Have mf4355 here and she's started to run hot the last few weeks. Got the thermostat changed and improved a bit but still running hot some days others it's fine. Could it be the water pump. Lad coming to look at again next week

Has it a sloped bonnet?

Dozer1 · 13-05-2022 11:48PM

Yes snoopy nosed one

FintanMcluskey · 13-05-2022 11:58PM

They were at the limits for cooling at the best of times.

Check that the radiators are clean before checking the water pump

Get yourself a pistol grip air nozzle, they’d be around €15-€20 and blow out all the radiators.

New Holland’s and Fiats here and they all run at exactly half way on the temp gauge. As soon as the gauge starts rising above that we know the radiators need cleaning. Straight after blowing out the radiator the temp gauge drops back to the middle.
