Not knowing exactly how my concrete would have handled a two post lift, I would have had to bust out and pour new supporting concrete bases for a two post lift.
I was also curious how critical knowing the balance point of each setup would be for each type of "lift" on a two post lift. When lifting a vehicle, that wouldn't change once you've determined it. But for using the lift for a tractor and its implements....how critical would it be?
Such as loader on or off? Backhoe on or off? Then there's the rototiller, flail mower, snow blower. And figuring out actual lift points on the rig for each of those situations?
After having this lift for a couple of years now, mine gets used for the tractor and implement cleaning/maintenance much more than doing vehicle maintenance. It just seems too easy to not worry about weight distribution and just back up onto or drive up onto and go to work. As an example: when changing and sharpening blades on the flail mower or cleaning the deck of the rear finish mower.

For a two post lift, I would have had more money invested in just the concrete work vs. this lift. But barring that, would a two post lift be just as easy to use in reconfiguring the lifting points without any other special adapters for non vehicle lifts?
You raise some very good concerns about lifts in general, in doing some research there are a number of key considerations:
Most 4 post lifts are not suitable for lifting a tractor as their lift capacity reduces drastically based on reducing wheelbase. For example a 200” long ramp on a 4 post lift that is certified to 9,000 lbs, will lift a regular F150 pick up, however the manufacturer is advising that it has a safe capacity of only 25% or 2,250 lbs for something with a wheelbase of 90”. Most 4 post lift owners are not aware of how significantly the manufacturers change the safe lifting capacity based on shorter wheelbase.
For 2 post lifts, you have to have some idea where the center of gravity is for whatever you are going to lit and also what type of lift adapters you are going to use at the end of the lift arms. An ALI certified lift will come with a guide of how to lift most vehicles, arm placement, arm adapters etc. As you comment you must also have a suitable floor to mount and safely use a 2 post lift, many users have to modify their floor at great cost.
I would never consider lifting a tractor with a 2 post lift and it’s 4 arms, tractors do not have lift or Jack points in the same sense as a car or truck and center of gravity for a tractor is very variable.
My original post is about Turf Rail which is a clever frame and rail system that quickly fits on a 2 post lift that is typically rated at 10,000 - 12,000 lbs. This 2 post lift adaptor provides 2 wheel trays that can be placed at any wheel base below 126” and will lift an item such as a tractor by the wheels, taking away all of the issues about lift points and center of gravity. The Turf Rail lift system is rated to lift 7,000 lbs and the adjustable wheel base of the lifting trays allows you to safely lift anything with wheels from tractors, UTV, atv, golf carts, mini truck, zero turn mowers, lawn tractors, snow blowers …….
As many people comment these 2 post lift adaptors are not cheap. I’m already installing a heavy duty 2 post lift for general truck and car use, so I will already have a 12,000 lb lift available to me. My mind started to wonder as to how I could use that existing 2 post lift to work on my tractors and other outdoor equipment, as usual I am not the first to raise these thoughts and quickly found a number of solutions available in the marketplace. I considered Turf Rail to be the most versatile, safe and easy to use adapter for a 2 post lift, it’s also the most expensive!
I hope my research and thoughts help any other forum user who is looking for ways to solve the issue of how to safely lift their tractor and other equipment.
The lift market is a strange place, you can buy a lift from about $2,500 to $15,000 and they look pretty similar, a key factor is certified or non certified. Do your research.
