Logan Hydraulic Clutches Provide Maximum Torque Transfer

A core value at Logan Clutch is its enduring support for future engineers. Through its partnership with the American Society of Agricultural and Bioloical Engineers (ASABE), Logan donated a P450 series clutch to be used for ASABE’s National ¼ Scale Tractor Competition. This tractor building competition challenges students to engineer a durable and maneuverable tractor according to design specifications. Each team is given ASABE-chosen foundational parts, which include a 31 HP Briggs & Stratton engine, a tire set from Titan Tire, and a Logan P450 series clutch. The rules of the competition limit foundational part modifications. The body, drivetrain, transmission, weight and size is up to each team’s engineering creativity and prowess.

2021 Year in Review 

Jacob Loutch, Previous A Team Leader 

This past year has been full of ups and down. After taking a year off because of COVID restrictions, the Power Pullers Club at Iowa State University has pushed the edge of innovation with their 2021 tractor, Cylencer. Our competition, the ASABE (American Society of Agricultural and Biological Engineers) International 1/4 Scale Tractor Student Design Competition held in Peoria, Illinois, provided the perfect environment to showcase our achievements. 

Unveiling a competition first, our team integrated the CY-shift three speed powershift transmission into their sub-compact tractor line. CY-shift utilizes four independent, hydraulically-actuated clutches to engage and disengage constant mesh gear sets to offer seamless shifting without a loss of power. Other key features for CYlencer included a fully suspended front axle and the all-new CY-Stick for tractor control. 

Diving into the fully suspended front axle, it is evident that Cylencer offers many benefits for the rider. Linear guides allow for three inches of vertical travel as well as axial pivot for side-to-side oscillation. This, along with adjustable coil-over shocks, allows the entire front axle assembly to move which reduces shock loading as well as stress on the frame. 

Looking into the CY-Stick, the Power Pullers Club looked towards ergonomics to craft our design. Gears can be shifted up and down with ease using the toggle switch located close to the operator’s thumb.
