Disassembling a governor on a Cub 184 loboy

Hello, I recently purchased a Cub 184 lo-boy with a 60 inch international deck under it. I have been mowing with it for a couple of days now and I have noticed that when I get in some relatively tall grass with the deck all the way up it just bogs down and the motor dies. I believe it is something wrong with the governor. The linkage is all free and moves nice. Has anybody taken one of these governors off before if so then can you tell me how to take it off and what to look for? Thanks for any advice! -Henry
 
If the governor wasn't working it would bog down and die with any load, not just in tall grass.

You've only got so much horsepower to work with. IH said the 184 had 18HP but that was... optimistic, to say the least. Several years ago a Cub enthusiast built a dyno for Cubs and measured several. The 184 was the strongest but even that didn't break into double-digits.

Unfortunately you can't expect that tractor to be able to take a full cut in tall heavy grass.
 
Thanks for replying! Is that why they added the creeper
gear for an option? If I could go slower I think it could
handle it.
 
The creeper gear is primarily for the rototiller and snowblower options, but there's no law saying you couldn't use the creeper for mowing heavy grass.

BTW on the governor, they're not that complicated. The spring that controls throttle response is external so you don't even have to take anything off. It's on the output arm of the governor kind of front and center on the engine. I've changed them without taking anything off. The one on my 1967 Cub was kind of stretched out and a new one gained a few RPMs and made the throttle response much better.
 
When I bought my 184 5-6 years ago it had way less guts than expected and found out the timing was way off. Fixing that helped a lot but that is not a power house tractor. I would make sure its tuned up according to specs and the governor adjusted correctly and unless the engine is wore out you will have all the horse power you are ever going to get with that tractor. I have mowed through some spots in my yard that were quite big compared to normal yard height and it made the tractor work but got through it. I mow in first gear. I believe a creeper gear was an option so maybe you have it and maybe you don't. Without the lower speed it won't mow grass much higher than missing a week of mowing in a typical yard. Even if you have the horse power you can't tighten the drive belt tight enough mow real high grass without the belt slipping.
 
There was a relatively large snow blower that could be used with that tractor and I think that was the reason for the creeper gear being an option.
 
Thanks every one for your advice! I have decided I am not going to do anything to the governor. One last question does anyone know where to check the transmission oil and differential oil? Thanks! -Henry
 
Check full throttle RPM. I believe it should be 2510 RPM. Check to be sure. A couple hundred RPM makes a big difference. These have a flimsy throttle cable. Usually the cable conduit anchor at the throttle lever bends.
I replaced mine with mechanical linkage to solve the problem.

Does your throttle lever stay at full throttle? If not tighten the throttle friction adjustment.
 

Ok I will check the RMP of the motor sometime. The throttle does seem to vibrate down a little but it is already hard to throttle up what are you supposed to adjust? Also do you know how to check the transmission oil on these?
