I need some help with a 149, I know this has been covered many times but I can't seem to find it in the FAQ's so don't shoot me. After I mow about 10 minutes the 149 will backfire and shut off, sounds like it is turning over but will not start until you wait about 5 minutes and hear a loud snaping spring loaded noise, then it'll start and you can do the same thing again..can anyone shed some light on this for me??

Richard, sounds like a sticking exhaust valve. You might be able to get it to free up with liberal use of MMO (Marvel Mystery Oil) mixed in with the gas. But with a run time of only 10 minutes it'll take quite a while to get it to work.

I'm looking over this 109 and I think the mechanical PTO is going to need some work - I think.
There is no button on the end of the rock shaft flat bar that presses onto the PTO.
Can someone explain the basic operation of the PTO?
I looked up the serial numbers on the tractor and it's build is June 1973. Would this year model have any safety switches on the PTO or any where else? I haven't seen anything yet that looks like a safety - anywhere.
The tractor came with a 44 inch deck and a front blade. I'm wondering how this 10 hp is going to handle a 44 inch deck. Also, I gather that deck design/style changed during the 1x9 production. Anyone know what drove the redesign? Which is preferred, old or newer style decks?
Lastly - was hydraulic lift an option on these tractors, and if so - what is involved with converting over to hydro lift?

Paul, you've likely forgotten more about Cub Cadets than most of us will ever know. I know I've learned a bunch from you over the years.

Hi Bill, the only safety on a 109 is the clutch/brake. it has to be depressed when starting.
i don't believe hydraulic lift was an option.

Bill, the mechanical PTO is actually quite simple once you understand it. Have a look at this cutaway view:
When the "Thrust button" is released it applies the spring pressure on the fiber disk (the thing with the cogs on it) and allows the crank shaft to effectively be connected to the pulley thus causing it to spin. When the thrust button is pressed in, it disengages the pulley and the crank shaft would spin within the bearing inside the clutch pulley assembly, allowing the pulley to remain stationary. Make sense?
Hydraulic lift may have been an option on the 109 but it would have required a ported hydrostatic pump. I believe that IH was touting the electric lift as the optional lift on the 109.

Bill Jamison,
There are only 2 safety's that I can remember on the 1X8/9 Wideframes. This is in stock configuration, and could have been bypassed by a previous owner.
1. Clutch/Brake ON - Clutch/Brake peddle must be applied (pressed down) during the start process. If the peddle is not depressed, or locked down, the starter will not engage.
2. PTO OFF - The PTO must be in the off (disengaged) position during the start process. If the button has been depressed, and the PTO lever is in the "leaning forward" (engaged) position the starter will not engage.
Dad's #1 149 is still all factory and has these 2 working safety switches. I have operated other wideframes that do not need the brake depressed, and/or the PTO in the off position. I believe the the wideframes are some of the first with the safety switches on them. On the Zig-Zag 124 we had, it had no safety switches at all on it, nor the provision to have the safetys. The later series have a seat switch, brake, and PTO. I do not think any IH Built Cub Cadet ever had a reverse mowing switch (can't mow and back up at the same time - what a PITA!) Hope this helps.

Bill J there should be a safety switch on the handle that engages the PTO. Look under the dash behind the gas tank on the right side.
Paul W on the 147 electric lift try wiggling the wire on the motor as you try the switch. On mine the plug in connector doesn't always make good contact.

Ray-
I really like that little cultivator. Could you post some close-up shots of it? Is it homemade? I'd like to make one like that with the spring tines. It looks to do an excellent job too.
Thanks for the pics.
I just got the pto off of the nephs 128. I had some help from a member waaaaay up north of the border via email (thanks Don). He suggested heat which I had thought of but the thought came and went because of the fiber disc. After his idea I decided WTH. If the disc gets toasted then it's better than drilling. I haven't really inspected things yet as the pto has been cooling (and that's hard to do here in the south in late June). All of this was just for a worn thrust button. The pto is/has been in good shape and should be in top form by tomorrow.

Norm Bartee: Steve may have more to offer, but the biggest issue I can foresee trying to shoehorn a Kohler M18 into a 1450 is physically fitting the motor within the frame rails. The reason IH went to a "spread frame" for the 82 series tractors was specifically to lower the frame rails to clear the opposed cylinders of the B&S (16 HP 582), Kohler (17 HP 682/782) and Onan (19 HP 982) motors.
If you cut the sides of the frame, you will have a lot of re-inforcing to do in order to preserve it's strength.
You might have better luck with a B&S, Kohler, or Honda V-twin although I can't speak to whether they would work or not, at least there is a better chance that they will fit between the rails.

Bill J,
Early 1x8/9 series had a single safety switch on the clutch/brake pedal that required it to be pushed down to start the engine. Late 1X8/9 models had two, one on the clutch/brake pedal and a second one on the PTO engagement level as previously mentioned by others. The way to know which you have is by checking the front PTO. If your 1x8/9 model has a brake shoe on the PTO to stop the PTO from spinning when disengaged, you have two safety switches. I think this production change occurred in early 1974 which was the last year that series was made. The CC parts lookup at the top of page will tell you the serial number break when that change was implemented.
