Bush hog

[1930]

Good morning, is it normal that these blades be loose?
I know nothing about this, I need one and it’s been sitting
The bolt/ nut is tight, just sloppy from wear.
Not stupid loose in my uneducated opinion but definitely wobbly.
Someone has just abused this thing
Thanks

They should be able to spin around the nut. If it hits a stump, they can absorb the hit better (by spinning backwards). As for how "loose", mine are somewhat tight and takes a little effort to spin them.

That one does look to have been used a bunch... What price are they asking?

It came with a B6100 I bought years back
I unhooked it and dropped it not thinking I’d have need for it

I would worry more about the gearbox than the blades. Before I used it, I would try to tighten the blades but also, change the gearbox oil.

I pulled the plugs on it and no detachable fluid so I’ll fill it up and see what happens
Thanks

There may be some life left in the old bush hog yet.

Good luck.

The blades are "lose" so they can swing back if they hit something like a rock or a stump. In normal operation, centrifugal force keeps them extended in cutting position. Fill the gearbox with 80w-90 gear oil. If it leaks, use cornhead grease.

Correlation of blade to bolt appears fine to me. As others stated blade to blade arm needs to have a little clearance so blade can rotate away from unknown obstacles encountered when mowing.

I wouldn't fill it up too much, just enough to see if it's leaking out the bottom. Maybe fill it to a certain level. (My guess it will leak). Cornhead grease 00, works well if the bottom seal is shot...

Surprisingly the box took very little gear oil and cuts like a champ considering all things.
The B6100 is probably too small for it so I have to put it in turtle mode but I’m still at the learning curve.
Can someone tell me what the chain may have been used for?
