Swisher Rough cut 52 only cutting one side

[MarDawgVT]

All,

We have a Swisher rough cut 52 inch with a 17 hp B&S motor.

It will cut great on the right side and leave the left side partially cut.

I have contacted Swisher and they have been very responsive but have yet to figure out why

To date we have done the following:
- New drive belt
- confirmed the belt is tight
- installed brand new blades, then installed new high lift blades
- blades swing free
- blades are installed correctly
- new spark plug
- we have tried mowing a 1 mph, 2 mph, 3 mph, 4 mph, and 5 mph - all the same
- we have tried offsetting the mower to the tow ATV - both right and left - all the same
- we have tried all the way up for elevation, front middle setting - back up all the way, front low setting back middle...

The customer service person has worked with engineering and there is no resolution

Any advice would be greatly appreciated or if there is another forum where I can seek assistance please let me know.

Welcome to TBN. I rarely see one of these, so technically I'm not much help. One would think that However either a blade hub or spindle pulley are located on the shaft IE a spline or key- has spun and isn't driving. Time maybe to swap part positions and if you can't see what's what.

This is a single spindle driven off the B&S motor.

On the cutting spindle there is a stump jumper and has 2 swinging blades that come off that single spindle. Very similar to how a Woods brush hog is configured

In that case I would expect the blades to hit something to cause them to swing inward. Centrifugal force should keep them extended unless they encounter something. Ever try just mowing where only the problem side is cutting? or vice versa?
Blades are not hitting the deck (top or sides) on that side?

Post the actual model number. This may help ID what you have.

Honestly I'm not sure what the pictures are showing; looks like there's like 1' getting cut to the ground and very little else, though without anything else for scale it's hard to see what's what.

If there's really a left/right issue I don't think it's front/rear elevation but instead left/right height is not level - be that deck or spindle. Something really bent?

Can you clarify what we're looking for in your pics?

no blades hitting the deck as they would make serious noise.

I am thinking of doing a test where I extend the blades out and then tighten them so that they would not swing inward and see what happens,

Do you see any downside of doing that as long as I don't hit something hard?

Thanks

Interesting...looking forward to updated.

If you stay away from rocks, stumps and stuff that should prove something. If they do move you know something as well. I would make just tight enough to stay but give if something solid comes up

The likelihood of them moving inward only on the one side - every revolution - without hitting something (and making a huge racket) is vanishingly small.

Can you verify that the blades are level when extended at a stop, and the spindle driving the blades is vertical and perpendicular to the plane of the blades?
