RH stander engine question

I've got a 2008 Wright Stander RH, 52", 19 HP kawa engine...When I turn the blades on at full throttle, it really bogs down the engine, to almost shut off. What would be the reason for this? Or what will fix this issue?

BLS33,

Either the engine governor is not responding to the increased load and not increasing the RPM,s or there is a bind condition in the spindles or clutch. Behind the throttle plate on the engine you should see the governor moving when the blades are engaged if not it will have to be repaired. For the spindles you can remove the belts and check the spindles for play or roughness when they spin. For the clutch engage it when the deck belts are off, if it bogs then the clutch is binding (if the governor works).

Best Regards
Wright Mfg.

I should have said it bogs down for a little bit then fires up to normal speed. Does that change the diagnosis?

BLS33,

So it sounds like the governor is working, but something could be still be causing drag on the system. Still a good idea to check the spindles, does the deck sound like it is making more noise than usual? Also how many hours are on the unit? Does it seem like the engine runs normal when not under load?

Best Regards
Wright Mfg.

I don't notice any unusual noises. About 750 hours on the machine. Seems to run just fine with the blades off.

When the belt is off, there is a little side to side play in the clutch. I'm assuming there shouldnt be any? Can it run like this for a while or can that cause more damage? Whats the cost on a replacement? And how difficult is it to replace?

BLS33,

If you mean the clutch will move side to side on the clutch stop that is normal the clutch has to have that movement. Check to make sure all the electrical connections related to the clutch, operator pressence switch, relay, and time delay(rectangular plug in on harness) are clean and secure.

Best Regards
Wright Mfg.

Turns out is was a dirty/loose connection. Thanks for the help, mower runs perfect now. Just a couple general questions, do you know the rough weight and fuel mileage (hrs per gallon)?
