GRANT BORCHARDT | TARA, QLD

Grant Borchardt, from Tara in central Darling Downs, Queensland was one of the first owners in that state to fit RFM Auspoint double discs and coil press wheels to his toolbar, four years ago, to overcome hairpinning and mud-build up when planting into stubble.

Grant runs the 8,500 acre property, ‘The Deep’, in conjunction with his son-in-law and sharefarmer, Peter Fourie, and they have 47 double discs and coil press wheels fitted on 10" spacings operating on two metre controlled traffic tracks. “We were originally looking for a disc-type machine”, Grant explained, “we didn’t want to spend a lot of money and other machines that we had seen had mud build-up. We find that the leading scalloped disc on the RFM Ag set-up shifts the stubble and avoids hairpinning."

“With the 10 inch spacings in wheat there is a lot more weed suppression. We sow 4" deep at 11 kph – wet or dry. The coil press wheels give us very good soil to seed contact. And they do a brilliant job. They don’t block up and we don’t get that Kinze crack problem."

“The front sowing boot made a hell of a lot of difference to the precision seeding. We experienced a huge improvement in germination."

“We planted for a neighbour and it was the best crop of oats that he’s ever had.” “We have done a total of 20,000 acres and the benefits that we have found are ease of operation, lower costs and maintenance, and better germination”.




RICHARD KIRKLAND | FURNER, SA

 

Richard Kirkland of ‘Kirkland’, near Furner SA, trialled two RFM AG double discs on his 30’ Flexicoil ST820 tillage bar in the blackest, stickiest soil. He was so impressed that he fitted his machine with 39 double discs. “I think they’ll work anywhere”, Richard said. “It took two half days to fit the double discs and we didn’t hurry it. The stony country around here is usually an issue, but the discs handle it well. In the stubble on stony ground, the tynes kept digging up the stones and sometimes stubble clearance is a problem.”

Richard crops 1500 acres of broad beans, wheat and fodder crops and pasture, plus he does a bit of spring contracting, mainly pasture work covering around 5000 acres. He said that he sowed a paddock on the stoniest country around for a customer. Sowing the pasture seed at about 1cm, the discs covered over well and performed admirably.

‘Kirkland’ has heavy black clay soil, ranging from sticky to moderate, in a 500mm rainfall area. Richard tows a Flexicoil air seeder behind the bar with a CASE 305 tractor, and he found that he is now using just 60 to 70% of his usual engine load. “We sow at 12 to 14 kph and that equates to two litres less per hectare. Pulling the bar has proved so easy that we have taken the duals off the CASE.”

Richard also trialled and purchased a set of Ryan press harrows.

NEALE POSTLEWAITE| ST ARNAUD, VIC

Neale Postlethwaite, is cropping at St Arnaud, in Victoria and identified a rhizoctonia problem some years ago.

“Our aim is to cultivate below the seed placement so we use deep banding to open up the soil to put the fertiliser below the seed placement and fix the rhizoctonia.

They operate their own design planter and bought 35 RFM double discs for the 2014 planting because their tractor’s front wheel assist failed and as they were planting in very wet conditions, their tynes would not have been pulled. Using the double discs there was 40% less horsepower required.

“We can certainly see the benefit in their use for dry sowing in conserving moisture. There are benefits in using the discs without having to lock in a whole machine. It is certainly a lot cheaper. We can change the tyne system to discs in a couple of hours.”




GAVIN FORSTER | SENIOR, SA

 

Gavin Forster, from near Bordertown SA, operates a 36’ Case 4300 bar with double discs at 12" spacings. The soil is generally sandy loam, including non-wetting soil that has been clay. It is crabhole country and flats that have been delved to mix the clay through the soil profile.

“On our rises the discs left the stubble where it was and avoided moisture loss. The tynes usually rip the lucerne up out of the ground – the discs didn’t damage any of it.”

“The discs were easier to tow – we found that we just can’t go fast enough – 11.5 kmh with the discs, 9 kph with tynes. We had minimal soil throw, when dry and it was sticking when wet. It works well on all soil types.”

“I’d recommend them – it really depends on what you want to do – what the problem is. We were really impressed with the strength of the RFM gear compared with coulters that we have used before.”

“We had no issues in stubble, and no mechanical issues, moisture retention is important – tynes are going to dry the soil out. We are saving diesel with the double discs.”

NEIL RAMSEY | RAMERVILLE, SA

 

Neil Ramsey, Ramerville SA, has a 63’ Flexicoil bar with 72 sets of RFM Ag double discs. The seeding boots are fitted with two sets of spray nozzles for liquid fertiliser and trace elements. They pull the planter John Deere 8960 with triple wheels front and rear.

He farms 3700 ha of canola, wheat and barley. In stony country using conventional tynes they were sowing at 4kmh – “Plus the time spent tightening everything up!

“In the better ground we would do 9 – 10kmh. “With the double discs we now sow at 12 – 14kph – wet or dry, getting down to 10 kmh in the stony ground.

“We have reduced our fuel use during sowing by 30% - we’ll never go back to tynes. The only blocking was between discs. Timing is paramount”.




GLEN OGDEN | DALBY, QLD

 

Glen Ogden, from Dalby Qld plants cotton as his main crop, along with sorghum and wheat.

He plants anhydrous oxide into the black soil and now believes that he has the best cultivation equipment to do the job. Glen has fitted 33 RFM Ryan tyne-trip double discs and tyne-mounted RFM Auspoint coil spring press wheels to his John Deere 1610 Chiselplow.

“This set-up is doing as good a job you’ll get”, said Glen. “It is far deeper than the Excel’s single disc that we have tested. We can get going again in four to six weeks.”

They have done 3000 acres so far and Glen explained that they plant at 9 to 10 kph in very hard ground at approximately 8cms depth with variable spacings.

“It keeps more gas in the ground. When it is wet the press wheels are very good. Its ability to shed the mud is what sold me.”

LAWRY SIMPSON | OAKLANDS, VIC

 

Lawry Simpson grows wheat, canola, barley and sheep on a 600ha property between Jerilderie, Berrigan and Oaklands in southern NSW and has a CT Guidance 3340 with 12" spacings and press wheels, pulled by a Case 305 Magnum.

The soil is light and sandy through to very heavy sticky black clay, which he says proves the versatility of the double discs.

“We found that this would go through the ‘plasticiny’ stuff very well. It handles and incorporates the stubble very well. No issues of trash building or blocking.”

“We sowed the canola at 3kg/ha and we had good enough germination that we could have sowed lighter. The wheat was sowed at 2cm depth, and we could have gone down deeper with this machine.”




BEN LAWRIE | WESTWOOD, NORTH QLD

 

Ben Lawrie, from near Rockhampton, North Queensland, was originally looking to get on top of the Feathertop Rhoads problem in his cropping program at ‘Evergreen’ when he looked around for a better cultivation set-up.

He has had 23 double discs and press wheels on half-metre spacings fitted to a very much modified Gason 3100 Trashmaster bar for two seasons now. “We wanted to try something different. This is an inexpensive conversion and we wanted something simple.”

Ben said that he has done 1,000 hectares all up so far with no problems. The cultivator is pulled with a 115 horsepower New Holland and he says that it is simple to run; “You don’t even notice the load if the soil’s good. The tractor handles the 23 discs well at just 12 litres/hour.

“The discs are much better than a tyne in the wet. We get a soft return from the disc.

“The double disc and press wheels combination has far exceeded our expectations."

Reliability is good – no bearing problems, press wheels on all the soil types are fine”.
