Got a Kuhn 1999 model MDS1141 (Similar to axis 30), holds 2 tonne maximum I spread is 600lbs over 80 ft at 7 mph. Once calibrated it is dead accurate and the double overlap helps minimise misses. Do about 180 tonnes per annum through this machine every year. Only bother I have had is the top bearings on the gearbox when left over the winter corrode due to condensation and vanes on the discs can wear quite quickly and they are quite pricey but I will buy another Kuhn. Had an Amazone before which was a rusty heap.

Bogballe an excellent spreader local potato guy has one spreding 1100lbs/acre fertiliser at 40ft at 6mph although I spoke to a fertiliser rep yesterday who said the Kuhn was better because its discs spun slower therefore didn't break compounds up.

Lots of guys here had the boom with the spreader mounted behind but most weren't up to the job and 1/2 tonne bags twisted them plus you need extra weight on the front of the tractor as they telescope out 5+ feet further if the front lifts and the spreader takes the weight the gearbox can become twisted and leak.

We travel back to the yard to refill with the telehandler tractor does 31mph so doesn't take to much time and furthest field is 2 miles away. Although some guys have farm trailers with motors and Hiab cranes attached

We spread everything from straight N 34.5% through 24.0.14+7S and on to Murate of potash and MAP 12.52.0 all to 80ft and up to 10mph as well as grass seed and stubble turnips at 4.5lb/acre at 40ft centres.

Cheers BB
