"The majority of farm tractor front end loaders that are available on the market are made to agricultural standards not industrial standards. The use of low quality agricultural grade components such as hydraulic cylinders are commonplace on these agricultural type loaders, whereas high quality industrial grade components are fitted to industrial loaders. Constant heavy duty use of agricultural loaders for tasks such as clearing rocks, shifting large hay bales and earth moving soon fatigue the lightly constructed frames and components, leading to their ultimate failure. This type of work subjects the loader to different dynamic loads. Most of the farm loaders currently on the market are designed on the basis of static loads. Static loads are many times less than the dynamic loads, placed on the loader. Dynamic loads are the result of, rapid application of load, resonance between members, periodically varying load, impact blows and shocks. " -- Abstract/Synopsis.
