When I raise deck it is uneven so will not cut grass level

A: Scribbling the frame:
-Possibly the bolts on the wheel are lose. And it turn warble that's why it scrub the frame.
B: Uneven cut:
-Uneven cut is not the tire or wheel. Possibly the height adjust on the cutter deck is broken or lose bolt. Or may be bend cutter blade as well.

Good luck

Hello,

I am guessing that this was posted in wrong category.

You mention that you have to keep pushing / letting go of the accelerator. Is the engine RPM changing, or is the tractor surging, when you do this? What happens if you keep a steady pressure on the pedal? Isn't the throttle control via a lever on the panel?

Your uneven blade height can be caused by a multitude of issues.
1) If the spindles were changed, the wrong spindle may have been used on one side or the other.
2) The wrong blade adapter has been used on one of the spindles.
3) Mower deck has been bent
4) Mower deck is binding. Try raising it all the way up, and lowering all the way down. See if the uneven cut changes at both levels (all up or all down).
5) Blade is bent on one side, though this would usually cause such a ruckus and vibration it would be quite noticeable.
6) Belt is slipping. Yes, sounds strange, but if blade speed changes significantly, then the position where the grass is actually cut changes because the grass can "lean over" more.
7) Using a mulching attachment in tall grass can cause 1 blade to clog, and the cut grass that is swirling bends over other grass that needs to be cut.
8) Mower deck support bracket has been bent
9) Mower deck wheel has a bad bearing, and doesn't support the deck at same height as other side.
10) Mower deck is cracked / bent at a support location
11) You have lost a retaining pin at a support bracket and the bracket is loose.
12) A spindle's bearings are worn out, and the spindle is "jumping" as it turns.

If the blades are directly beside each other where they blades will overlap, it is normal for a small amount of height difference to occur. But, most decks have off set blades, one slightly in front of the other.

you should be able to raise the deck all the way, and pull the tractor's front wheels up onto something (landscape timber?) to get more access, then measure blade height in relation to bottom of the deck. If different, then you are looking at wrong blade / adapter or a spindle issue. If the blades are the same height, then you are likely looking at a deck support issue / binding in linkage.

Park mower on a level flat surface ( a concrete garage floor is ideal ) lift deck up until you can put a piece of a 2x4 flat underneath the deck and lower deck until it just contacts the 2x4. loosen adjustment nuts or turnbuckles and adjust until the deck just starts to clear the 2x4. this should level your deck. Now , lift the deck and remove the 2x4. put blade height lever on a known cut length and with a tape measure, measure the tips of the blades from the floor to the blade tip...they should all be the same within 1/8 of an inch...if not then you either have a bent blade, bent spindle shaft, or spindle bolts are loose or misaligned. Your deck could be warped too...depending on how hard a lick it took...good luck !!! ;-D

Look under the mower deck. If you can't see well and work on it, you may have to remove the mower deck and flip it over on the ground. Grass and mud buildup in the decj could cause a blade to pinch grass, 'scalping' the lawn. Clean it all out. Dull blades cause cut grass to look torn and brown. Remove and sharpen. Bent blade will cause uneven cut. Replace it. Good luck! Please rate if you found this helpful, thanks!

It needs to be leveled. Level it from side to side and front to back, then drop the front 1/4" lower than the rear. The hangers holding the deck in place are adjustable.

Are your blades upside down? Mower deck level?Proper air pressure all 4 tires?Correct blades for the diameter of cut? Deck bent? Deck hangers bent?

First make sure all the tires have the same pressure of air.

Then I would measure how much the one side of the deck is higher than the other. Then I would look under the tractor and there should be a horrozontal bar atatching to the deck and a bar coming down from the mower into this bar. usually there is a nut on the bottom than can be tighened or loosened to raise or lower the deck on that side.

There might also be a nob on the tractor that shows a picture of tall grass being cut, if you turn that that might also raise or lower the deck on either side.

I have seen dull blades, blades not installed right and an un-level deck cause that.

Hope this helps.

a lot of problems here.try this.[grass buildup]. usually cause by damp grass or blades not going fast enough to throw into box.engine cutout is then caused by grass jamming blade[s]. backfire is usually too much choke or wrong petrol/air mixture.re bent grass.try cutting driving in reverse[if strip is wide cos of back tyre then blade is uneven.]

check your front tire air pressures
