Just a reminder. The WIX/NAPA Gold oil filters will not work. Their base plates make contact with the oil filter mounting flange before the gasket can fully compress. This leads to an oil leak and possible engine damage. The Predator (Loncin) engine manual states use only the STP or FRAM filters...

What are you trying to cut? Brush? Unimproved land? From my experience, the cutting height settings rarely match actual cutting height. It doesn’t matter where the mower was purchased. Residential mowers will have anywhere from two to four adjustment points. Two adjustment points are common on...

You need to calculate your slope angle. In general, a lawn tractor is going to be better on slopes. The Kawasaki FR651V powers the X350. The engine manual states that it is designed for continuous operation at 25 degrees. The John Deere X350 owners manual says 15 degrees is maximum for safety.

I run 40:1 in all of my stuff too. I don’t see any reason to keep two mixes on hand.

That’s all fine and well for a residential owner. A commercial owner doesn’t have time to clean the deck after each customer.

👍

Read your owners manual. Transport position is for moving the unit while not under power. Do not operate the mower with the hydros in transport position. I would suggest polishing your mowing technique.

Just to add to my earlier post. My mower is Gravely Pro Turn 260. It has the X-Factor 2 deck and is powered by a Kohler ZT740. Yesterday, I mowed my three acres. When I started, there was still dew on the ground. The dew was gone before I finished. There were no clumps left on the lawn. There...

Were you having this problem before installing the new steering shocks? New steering shocks can be a little stiff and sometimes you don’t realize that you are giving a little more input. This can cause you to push a little harder. Then you over correct with the other lever. Sort of a zig zag effect.

I was referring to the older models. Look at @GearHead36 reply above mine. It reads as though he has the older model PAS.

I guess that it’s possible. However, it’s unlikely. Is your machine under warranty? If so, have it seen about.

With Echo, their Red Armor grease tubes will screw into the fill port of your machine. Also, you can take the plug down to NAPA and match the threads to a grease fitting. On the string trimmer head, you may have to remove the debris shield to fit the tube.

Manufacturers would rather sell a new gear box. I imagine that many residential customers would care one way or the other. I believe that @GearHead36 is referring to #2 in the second photo of @StarTech parts drawings.

A well designed deck. A deck that gives a good cut and discharges grass well. A deck that is simple to level. A deck that is has easy access to the belts.

That’s how I do my edger and string trimmer.

Check with your local John Deere dealers for the battery.

Have you thought about filling them with foam?

I for one am not thrilled with the so-called smart key pad starting systems. There is a need for some sort of monitoring system for the EFI engines. For the carbureted engines, the key is all that’s needed. Keep regularly scheduled maintenance as simple as possible for the end user.

Those 65 degree Yamaha V-Twins on Gravely were a nightmare to change plugs. Possibly the worst engine ever made.

Easy access to the rear of the engine. It’s a pain in the rear to remove the rear end of the mower just to adjust the carburetor or adjust the valves.

I hate Gator style blades. I don’t have the time to clean my deck after every 1/2 acre. I don’t have time to go over areas where big clumps havefallen from under the deck. That’s a big no to extra high lift blades. Gator G6 blades my a mess on my Gravely. The OEM blades do a fair job. However...

I replied before I saw yours. Try leveling the deck properly. You want it level from side to side and 1/8” to 1/4” higher in the rear. Use OEM or equivalent high lift blades. Rotary #11856.

You missed a couple. Deck leveled properly. Use high lift blades. Gator style blades will make a mess.

You’ve got to be kidding.

The newer Ferris Z3X uses Hydro-Gear ZT4400 transaxles. If that’s what your particular mower is equipped with then, you can use synthetic or conventional 20W50 or 15W50 synthetic. 177 to 120 ounces per side. https://www.hydro-gear.com/wp-content/uploads/2023/03/BLN-0081_4400_P6.pdf

Look at the photo that you put up. There definitely needs to be a bead put on where the two curved baffles meet. Your other problem is those Gator style blades. They aren’t good for anything but fall leaves.

That 3/8” higher in the rear doesn’t apply to all brands. For the OP’s Gravely, all blades are to be 20.5” in length, 2.5”wide, 0.25” thick, and have a 5/8” center hole.

I doubt that was the case. It can be made to cut better. However, a zero turn isn’t going to cut that stuff like a tractor pulled Bush Hog.

I went back and looked at the OP’s photo. Two things stood out for me. First is it’s a pasture type property. Using even a commercial zero turn, it’s going to need double cutting. Second is the rather large swath of partially and uncut grass. I would go straight to that center spindle and...

What would the anti-scalp wheels have to do with it? Are those anti-scalp wheels adjusted to be in constant contact with the ground? If so, they shouldn’t be.

I would look at the Ariens Apex or Bad Boy Maverick

Why are you shopping for low end residential mowers?

The anti-scalp wheel doesn’t matter. They are not supposed to ride on the ground.

Yep!

I’ve heard some people say that the Kohler engines are louder than the Kawasaki. I have no way to verify this. I do know that I can tell the two apart by hearing them mowing. I have the ZT740 on my Gravely. I don’t worry about the noise because I always wear hearing protection.

Here’s the parts schematic. However, you will need to verify this with your unit.

I use white lithium or silicone spray lube on things that don’t have grease fittings.

And, some tensioning pulley assemblies have a square hole to accept a 1/2” pull handle and extension.

I’ve used the NGK plugs on my Kohler ZT740. The gap is the same 0.030

Never mind. The cord works great on the deck tension springs.

A piece of 1/4” braided nylon cord or rope makes a good spring removal/install tool.

Pull the both plugs. Turn the engine by hand and Verify that the left piston is moving up and down. Also, pull the left valve cover and see if you have a bent pushrod. If you have spark on the left, there is probably something wrong with the left cylinder. Have you ever adjusted the valves?

I’m glad that you finally got it. Did you have to remove the mower deck?

Will dropping the deck allow you easier access?

Thanks for answering. I don’t see many diesel zero turns in SW Georgia. Those that I do see are either Kubota or John Deere. Every now and then I see a Grasshopper.

I’m curious. Why did you choose a Ferris over some of the other brands out there?
