How Strong is JD60 Lift?

The pump lives on top of the flywheel. There's a lever type "switch" you turn to engage the pump. Make sure you have the fluid topped to the petcock on the back - above and to the right of the PTO. Fill thru the knurled cap on the back, center, below the seat. The 3pt is controlled by the lever to the right of the seat with a neutral, fast, slow up and fast, slow down position. Forward raises, back lowers.

Frank's grasp of Newton looks good, but beyond the physics, those boom poles come in two flavors that I've seen -- 500 and 1000lbs. I've had the 500lb flavor on the back of my 60 a few times. The real question gets to be whether you like being able to steer the tractor, as it makes the front end very, very light. If 700lbs 8 feet back is possible, I think you can forget about the front wheels being on the ground. Move the load closer to the back of the tractor before lifting.

Be careful with that boom pole. A 60 is a little too big to be playing see saw with it. If I use my boom pole anymore, it's on the back of my 1020 with a loader -- nice counter balance weight up front that my 60 doesn't have.

Here's my S.W.A.G.:

I don't have some of the dimensions, so there are some assumptions in my figures.

Assuming the Pow-r-trol piston is 3" (not sure of that) and the pressure is set to mean of 1190 psi (spec is 1170-1210 in my 70 book), and the bellcrank from the piston to the lift arms is 6" centerline (another guess !), then:

Piston area x psi x moment in feet = foot pounds torque at the rockshaft.

So, 3" has 7.07"sq. area x .5 (bellcrank in feet) x 1190 psi = about 4200 ft.-lb. torque.

So, you should be able to lift (under ideal conditions) 4200# 12" behind the rockshaft, 2100# 2 feet out, 1400# 3' out, and 525# at the end of an 8' boom.

Lots of assumptions here, including can you keep the front wheels on the ground.

I may be way off, but it's a heartfelt try !
