'15 X738 Lift Arms- Need Help

Reaching-out to the community for help here.

I need my lift arms to raise my deck a little higher and drop it a little lower.

Is there an adjustment to allow me to do this?

When my deck is raised all the way up, the deck stops are over an inch away from touching the frame. Makes it a little difficult loading it on my trailer.

When I lower my deck to remove it, it won't go down enough to lay flat on the garage floor even after releasing the front bracket. It's still held-up a little off the ground by the rear bracket.

It's under warranty and I brought it to the dealer. They replaced the lift arms but didn't level the deck correctly so when I cut grass at a 4 1/2" tractor setting, it was cutting grass at 3" to 3 1/2" height! When I leveled the deck per the plastic tool, now the deck won't come off w/o wrestling with it.

Please help. If I could make the arms drop the deck another 1", I think it would work as it should.

Amazing that the dealer would chose to replace those robust lift arms instead of diagnosing the issue and resolving it.

There is only so much travel in the hangers. Make sure nothing is binding somewhere. To get more lift, tighten up the hangers all the way which will also require the front draft arms to be tightened up to relieve the deck.

Re: '15 X738 Lift Arms- Need Help

The deck stops on my x750 are about 1/4 of an inch from touching the frame when the deck is all the way up. You'll probably have to adjust the deck adjustment bolts to get the deck where you want it.

Re: '15 X738 Lift Arms- Need Help

The kit to level my deck is in the glovebox. It includes a t-wrench and a black plastic round piece.
Left-Right-Front level procedure sliding the plastic piece under the rear left, then rear right, then the notch upfront.

Raising the deck higher or lower defeats the use of the plastic measuring tool and the leveling process.

I can't get the deck to lay flat on the garage floor so I can back off of it so why would I adjust the deck even higher?

I can't go lower because setting the deck at 3" I would be mowing at 2". What's the sence in the leveling procedure at that point?

The numbers on my dial do not correspond in inches either. As I was told by my dealer, either rightly or wrongly, it's just a guide. Not sure why the deck on yours will not go all the way to the floor. The plastic guide that came with your mower is useless. My experience using that piece was frustrating, I couldn't get my hand under the deck to use it at the recommended setting. Deere also sells this gauge.

Re: '15 X738 Lift Arms- Need Help

I'm thinking the problem is in the dial-height knob?

There must one more notch to lower it one more notch?

Does that dial height adjuster get installed at the Dealer or factory installed?

Re: '15 X738 Lift Arms- Need Help

I'm sure that part is installed at the factory. The knob is connected to a cam under the floor/fender panel. Attached is a photo of what happened to mine. As you can see, it's pretty buggered up. It was replaced under warranty. If you can get the deck off, see what kinda shape yours in in. I really have empathy for you as I have been less that pleased with my x750.

Re: '15 X738 Lift Arms- Need Help

have a 758 that I think has the same adjustments . I sent the cut height knob at three inches lower the deck place a small wood 1x4 4 inches long on end under the blade(to the side) and mark the bottom of the 1x4 at the blade at the cutting edge . Now you know how far off the height gage is to high or to low . Raise or lower the deck with the adjusters both sides one turn each at a time until it is three inches the same as your height knob . The height knob should turn lower way past the numbers to lower the deck to the floor . If the deck still does not raise to the stops you will need to make a choice use the numbers on the cut height knob or have the deck not raise that high .

Re: '15 X738 Lift Arms- Need Help

If the numbers are not correct on the height twist nob, then John Deere shouldn't have numbers on it!

My Exmark numbers are spot-on accurate. 3" cuts at 3".

It really makes no sense to me to set the dial cut height to 3" and then be cutting your grass at 2". That's something I'd expect from a Chinese built junk product that sells for 1/2 the price of a Deere.

Thank you for the picture Rooster. I'm going to take a look under there today or tomorrow. I wonder if I could grind that wheel at the lowest setting to make the notch deeper allowing the deck to lower more?

Re: '15 X738 Lift Arms- Need Help

Sorry but you just do not understand how the knob and adjusting bolts work . The dealer will not let the shop take the time to do it right . It would take a good hour to fix . My x-758 has a 60 inch deck and after adjusting it if the knob is on 2 it cuts at 2 inches if it is on 3 it cuts 3 inches . Do as you like it is your mower .
