A few JD X748 fitment questions.

First of all the reason most of these mowers use the electrical clutch setup is to be able to use the safety interlock switches. The safety constraints have to be met by all manufacturers and is easily done with switches such as the RIO for backing up, operator presence, starting with mower disengaged. So more than anything it is a liability issue for all makers.

This same pto switch is used in most of Deere's equipment and I have read nothing about these being problematic. All four of my newer tractors use this switch. I changed out the switch in my L130 when I changed the clutch but it was still working. Haven't had any problems with any of them so far.

Hydraulic power is provided by the Tuff Torq hydrostatic axle on all models that offer power steering and power lift. Starting with the K58 tranny an (H) suffix designates the optional hydraulic function. So a K58H is what is used in the new x310 model. In the x749 the larger K92H is used which provides the necessary hydraulics for the entire machine.

In all cases for the newer equipment the power deck lift utilizes a small hydraulic cylinder powered by the hydro axle assembly. I haven't had any problems with any of this so far including the 3ph, used it extensively on the x749 today clearing away about 18 inches of snow.

About the choice of mechanical deck lift vs hydraulic, I have the simple mechanical lift on my L130 works great imo. If you are considering a larger heavier deck, snowblower or 3ph you will want the hydraulics.

As I mentioned in other threads the L130 is all I really need to mow my own lawn, the x749 comes into use for other uses where my tractors can't fit or don't wan't them to track up.

jenkinsph - What is your opinion on the X540?

I think it is a good mower and I like the larger wheels on it for floatation. From what you have posted floatation is a major issue for your soft ground. Most of these mowers are very close in ground pressure whether the 300, 500 or 700 series.

That said from what you listed ground is reasonably level and your intentions are to mow and maybe pull a small cart. Why not consider an x340 for alot less money? The 5xx series is better in that the tranny is heavy duty but do you need it for your intentions?

In all honesty, probably not. The X360 looks appealing, but i just like the slightly bigger size of the X540, and the liquid cooling appeals to me. Not to mention the better tranny and bigger spindles up front, should last that much longer.

One thing i didnt think of, would a smaller deck with 2 blades, versus a 54 with 3 blades, be easier on the electric clutch? Engaging 3 smaller blades instead of 2 larger ones probably isnt much different, but maybe enough to add life to the clutch?

The smaller deck would be better as far as the clutch wear and tear. I would first find out whether the electric clutches are the same on the 3xx and 5xx machines. I can't answer that. I think all of the larger riders have three spindles though.

I can tell you that when I start my 3ph chipper behind the 749 I am glad I have a heavy duty clutch pack.
