Several points,
First most of the postings reference compact tractors. They are NOT full frame/chassis tractors. Think about where this weight is supported. Typically it is the bolted joint between engine/transmission, sometimes an additional reinforcement toward the engine front.
Honestly, a ton should be a maximum lift pin weight. It was noted, machines designed to lift are configured entirelly different. I have two lulls and a hyster. They are full frame machines, weight borne on chassis, not engine/trans components. Reach the max limit you can obtain, you will then own a two piece tractor, a mirror will produce the responsibie party. Manufacturer will likely claim abuse. Court dockets abound with similar dispositions.

Quoting myself here from post 42. Would like to know how Messicks would address a potential customer whose sole purpose in purchasing was to constantly test the loader limits w/ a compact tractor and quick attach loader? The dedicated non-removable tractor loaders are much more durable. If constantly lifting loads at the FEL limits, is a compact really the answer? The Grand L no exception.
