Hi,
I have a Hustler Fastrac 44". When I bought the mower it it had a Honda 17hp on it. The Honda needed to be fully rebuilt and I had a Briggs & Statton 20 HP laying there so installed the Briggs on the Hustler. The Briggs came of a old Craftsman rider with a Manuel clutch and the Hustler has a electric clutch. When I try to engage the blades the engine stalls. If I pull the clutch out for 2 seconds or so and push it back in and out multiple times sometimes I can get the blades to start spinning fast enough to stay running. I can start the mower and drive it just fine, but as soon as I try to engage the blades it stalls and almost dies. The seat safety switch has been bypassed by the previous owner so that is ruled out. I couldn't find any parking brake switch anywhere that might be bad, but sometimes if you wiggle the levers a little, sometimes it will engage he blades just fine on the first try. So maybe there is one I may have missed?


Also somebody told me it may possibly be the stator because it came off a Manuel clutch and put on a electric clutch?

I have tried to engage the clutch with out the belt on and it does not stall. It's like the blades are putting to much load on the engine to keep them spinning.

The mower blades will all spin freely if you turn them by hand.

All the spindles and idler pulleys seem fine.

I have good spark with it running and doesn't change when I try to engage the blades.

Engine Model is: 407777 type:0167

Thanks Guys for the help!

How is your battery? Electric PTO needs 12v to stay running, you are onto something with wrong Stator. It will not charge battery while mowing now and blades WILL stop over time. You should re enable all safeties. We as a Forum can not condone that action, as you did not do this I suggest you fix it when able.
I would think that engine would be able to spin blades no issues.
Is the pulley stack the factory one?

The battery should be fine. I can Have it 100% Charged and try to engage the blades and it just stalls. Whats Funny is that I can mow for an hour, shut the mower off and it will start right back up with absolutely no problem, like it's a fully charged battery. Maybe I'm not mowing long enough.

Is there a parking brake safety somewhere I haven't found?

I thought the engine should be able to turn the blades fine as well

No the pulley stack is not factory. The one that was on the engine was for a manual clutch so I took that off and put a Electric clutch on there.( the one that came off the Honda.)

I will re-enable the safety's when I get a chance.

Thank you for the quick reply!

Wonder if a pulley is different size causing gearing issue?

I don't think so because the dealer said the pulley should be fine, but I would likely have a problem with a stator being to small. The one on there is a 3 amp I believe. Is there a minimum for a electric clutch?
Thank you!

If I put a bigger stator on, would I need a voltage regulator?

Hi
Have you had any grass build up under the pulley covers, have been told that it
will fill up under covers, was told to cut out small hold in end of covers and then you can blow the grass out.

Here's a long shot----Is the swapped Briggs an opposed Twin? If so, they can be known for weak spark from coil...any sudden load on eng may cause stalling....Tough to confirm...! Spark gap check...Carb could also contribute.., but usually surging noticed..Hopefully no internal problems, like worn camshaft...Knowing engines prior health and use would help...
I agree with your theory on battery...fully charged should not be a problem on clutch, for now...
