PTO Shaft for Supreme Feed Mixers 700T, 900T, 1000T, 1200T, 1400T, 1600T

As a specialist in agricultural power transmission with over 18 years of field experience, I understand that the efficiency of your TMR (Total Mixed Ration) operations depends entirely on the reliability of your drive line. The Supreme International feed mixers, including the robust 700T, 900T, 1000T, 1200T, 1400T, and 1600T models, demand a PTO shaft capable of handling immense torque loads and steep angles without failing. Our custom-engineered PTO shafts for Supreme mixers are designed to meet these exact specifications, ensuring consistent power delivery from your tractor to the mixing augers. In the demanding environment of UK dairy farming, where downtime can lead to significant nutritional imbalances in the herd, our 2580 series constant velocity shafts provide the durability and smooth operation required for year-round performance. Whether you are navigating tight yard spaces or operating at high capacities, these shafts offer the mechanical integrity to protect your gearbox and tractor transmission from peak torque spikes.

Core Principles: How the Supreme PTO Shaft Functions

The mechanical principle of the PTO (Power Take-Off) shaft is to transmit the rotational energy of the tractor’s engine directly to the mixer’s gearbox. For Supreme mixers, which utilize twin or triple augers to process dense forage and silage, the torque load is non-linear. This means the shaft must withstand sudden surges as large bales are broken down. We utilize high-grade cold-drawn steel for our lemon and star-shaped inner tubes, providing superior torsional strength compared to standard round tubes. The joints are forged from premium CrMo alloy steel and heat-treated to a surface hardness of 58-62 HRC. This ensures that the splines—the critical connection points—do not twist or strip under the heavy load of a fully loaded 1600T mixer. Furthermore, the inclusion of a telescoping mechanism allows the shaft to adjust its length dynamically as the tractor moves over uneven terrain, preventing axial thrust from damaging the tractor’s PTO bearings.

“A large-scale dairy farm in Somerset, operating three Supreme 1400T mixers, faced recurring PTO failures due to the steep angles required in their vintage barn layout. The original shafts were vibrating excessively, leading to universal joint failure every 4 months. After consulting with our engineering team, we supplied them with our custom 2580 Series CV shafts. The result was an immediate 15% reduction in fuel consumption due to smoother power transmission and zero mechanical failures over the last two harvesting seasons. The farm manager noted that the shear bolt protection specifically saved their main gearbox when a piece of scrap metal accidentally entered the mixer.”

Proper maintenance is the key to longevity. We recommend greasing the universal joints every 8 hours of heavy use, especially when processing high-moisture silage. Our shafts are designed with accessible grease nipples to make this process as easy as possible for the operator. In our manufacturing facility, we pride ourselves on our bespoke customization capabilities. We understand that not every tractor-mixer combination follows the standard length. Whether you need a short-coupled shaft for a compact setup or an extended reach for a wide-frame tractor, our engineers can build a shaft to your exact millimetre requirements. Our factory uses state-of-the-art dynamic balancing machines to ensure that every shaft leaves our floor with zero vibration, meeting the highest British and European agricultural safety standards.
