Makeing a Hoist

[Thats Hot]

I have a Hoist set up now I use it to lift my JD 170 and other small items. I have used this set up now going on 7 years now, the Elec hoist will lift 1300lbs. it is mounted on a steel tube 1'' 3/4'' x 1/8' wall x 11' span. I have 2 steel supports ""1 1/4" flat stock"" going up to the roof truss. I now have a Kubota B2630 it is give or take 1780lbs.I think at most if I lift the front up to change the blades I am lifting 600-700 lbs. my ??? is lifting the front to change the blades is the 600-700lbs sound about right to you guys. I did lift the Tractor day about 12" and put blocks under the front tires and all looked good, and the lift went good.
