How do I size the actuator (force and stroke)?
Documented on the Project Front Loader Pt 6: Linear actuator and build
Published April 27, 2026
Size the stroke so the actuator provides the desired bucket travel (raise/lower and dump angle).
Full Answer
Size the stroke so the actuator provides the desired bucket travel (raise/lower and dump angle). Force should exceed the expected load; for small lawn tractor buckets, actuators in the 2000–4000 lbf range are common. If unsure, err on the side of higher force and verify mounting geometry before purchase.
