Stump Jumper

[lead_dog]

Just bought a bush hog, which came with a stump jumper. I realize I should know what this is, but I don't...can someone explain it?

The simple of it is that .The brush cutter (I think all of them now come with a stump jumper) should glide or jump over a stump should you contact one to keep the cutter from getting stuck over the stump & destroying the cutter

A spinning wheel with a tapered edge will ride up and over an obstruction a lot easier than a flat bar. The flat bar will destroy itself, whereas the round disc will be around for the duration, if it doesn't rust out.

It's the frisbee-like disc that carries the swinging blades

It prevents the cutter from getting jammed on an immovable object like a stump.

Can you even purchase a cutter these days without one ?? I haven't seen one without in years


Hey flusher, That's a brand new cutter . It needs to cut some grass

Yes, you can. My JD 1517 just has blade carrier bars.. I also see some red, yellow and vlue rotary cutters at my local feed co-op along the fence leaning on post... some have round and oval jumpers.. some just have the carrier bar..

If I had just the bar.. I'd use that mower for 'known' pasture only.. Thusly.. my batwing only mows clean pastures.. If I have unknown ground.. i use my 10' howse with stump jumpers.. etc..

Some of the IMC (International Machinery Corporation, not International Harvester Corporation) rigs these days do not come from the factory with a blade-pan or "stump-jumper."

I may be way off base, but it seems that Big Bee may be in the same boat.


The blade-pan or stump-jumper is really just a piece of rounded metal around the spindle which prevents the gear box from slamming directly and without protection into a stump/rock, etc and destroying the driveline. Instead, it allows it to ride over or glance off of a fixed obstacel.

Today, there's no reason not to have it when buying any piece of reasonably recently built equipment.

Until as recently as 4 years ago, Woods medium duty cutters (MD series) were sold without a stumpjumper unless ordered as an option. I bought one and added the stumpjumper myself.

I wish my blades still looked like those!!

JD equipment is reasonably built.. I think that is a given.

Lack of a stump jumper on a light duty or finish mower seems perfectly acceptable as it reduces weight and cost.

Those seem like 'good' reasons to me...

If you are mowing light clean fields.. you don't need a mower built like an abrahms tank with a matching price tage.. when something lighter and cheaper will do... and still be a quality name brand machine.. etc.

I use mine for a rock jumper too.

Those photos are 2 years old. That hog is showing some wear now. But I only have about 7-8 acres to mow three times per year, so it'll be a while before that KK hog is worn out (unless I forget to check the lube in the gearbox).
