149 Lift Stop

[SharkyOhio]

I've been mowing with my 149, but it's been a bit frustrating because the lift handle stop and torque knob (#20 and #21 in the diagram below) are not working correctly. When I lower the deck, the lift hande stop moves--allowing the deck to go down too far.

I have tighened it by hand to the point where it takes two hands and a lot of force to get it loose. However, the hydraulic piston moves it when I lower the deck, making it impossible to maintain an even cutting height.

I have been working around the problem by leaving the deck in the lowered position the entire time while mowing, but it would be nice to be able to raise the deck when needed and lower it to a pre-set height.

Has anyone else had this issue? Any suggestions on a fix? I tried a lock washer, but that did not work...

you may be able to figure out what size the threaded part of the knob is and replace it with a bolt to tighten down with a tool. Maybe a small dab of loctite on the knob threads?

I don't think you should have to though, I am guessing something else in your linkage is worn.

Check to see if the float lock out pin is installed. it's a pin that goes threw # 22 on your diagram. If it is installed you it will actually put down pressure on your mowing deck and maybe thats why the cam lock stop knobs keeps moving on you because the hydro cylinder is pushing on it. You don't want to mow with the float lock out pin installed, the only time that you want to use it is if you want to have down pressure on a grader/snow blade.

Hi, If you use the round cam side of #20 as the stop it wont move. The flat straight part of #20 will never hold.

To add what scoobie said, I think there are 2 different stops. I had the wrong one on my 782 one time and the pivot arm #24 was hitting the flat part of the stop causing it to move. With the correct one, the pivot arm hit the round part of the stop. There's no way it should move it then. If you have the correct one, spin it til the arm #24 will hit the round part at the desired height then tighten it down. What do you mean when you say the lift cylinder is hitting the stop when the cylinder is on the inside of the frame and the stop is on the outside.

I'm in the float position. The deck is not moving down while I mow. It is being pushed down by the hydraulic piston.

Okay. I'm setup with the flat part of the stop making contact with the pivot arm. I'll try to set it up with the rounded part making contact.

Thanks for the tip!

Okay. Problem solved. It seems I had the part on backwards

Thanks again to DX3 for the tip

Below I have attached some photos to illustrate the correct set up.

Now if the relentless rain would just stop, maybe I can get some quality seat time in.

Glad you got it fixed, that looks correct now. Also I am diggin' your 149, very sweet looking tractor!
