We have the older CK35 (Shuttle, not HST) which aside from the Tier IV engine is pretty much the same tractor.
To add to what Sawworcs said about width, the wheels for the Ag tires are the ONLY ones that adjust. Turf & Industrial wheels are fixed (1 piece I think).
For the stability question - we are in the foothills of the Blue Ridge mountains - anything under a 10 degree slope we pretty much call level. Lol
We have loaded Ag tires with the wheels set to the widest width. There is no place on our property I *can't* go across the slope - there are places I probably *shouldn't* and most of the time I don't if I don't have to just because why tempt fate?
We almost never take the loader off so that's added weight and the two most common rear implements are a 5' box blade or a 5' rotary cutter so generally something of substance hanging off the rear too.
Coming from many years on a old 8N Ford it took a little getting used to the feel of the CK. If you measure from the center line of the rear axle up to the seat, on the 8N the operator sits much lower on the machine. Due to the flat floor on the CK, you sit a little higher up and when tipped sideways you "roll" laterally farther which makes it feel a little steeper than it really is. Just keep the ROPS up and wear the seat belt till you get a feel for where you can go & what it feels like (you really should use the ROPS and seat belt all the time).
When you are on a cross slope:
- don't hang out longer than you have to. Do what you need to and get off it.
- don't lift the loader any higher than you have to (this is really an all the time thing too) - it raises your overall center of gravity and makes it easier to tip over.
And lastly - listen to your butt (no not gut, butt) If you start to do something and your butt starts to pucker up - that's a warning sign that you might be doing something bad. :thumbsup:
Now, for a 3rd function up front, you have 3 basic options (and pardon me but I have taken to cutting & pasting this response between threads)
Option 1 - Rear Remote (SCV) $
Simply a set of long hoses to one of therear remote valves that runs to the front of the loader. If you go this route you will probably want an additional set of quick disconnect couplers in the hose near where the factory QD's are for your loader to make removing the loader easier should you ever want/need to.
PRO - It's cheap & if you ever decide to upgrade to Options 2 or 3 you can probably reuse the hoses.
CON - It won't be the easiest to operate since you have to move between the loader control and the Rear SCV control.
Option 2 - A Diverter Valve $$
Think of this as an Electronically controlled A/B switch. It gets installed between the loader valve & the cylinders the valve controls (typically the Curl/Dump function). Then you have a single On/Off push button on the loader knob. When the button is Off - the curl/dump function works like normal. When the button is On (Pressed) & the loader control is moved in the Curl/Dump directions, the diverter sends fluid to (in this case) the grapple lid to open and close instead.
PRO - You have proportional control of the operation and are able to gently feather the controls.
CON - You have to pick Curl/Dump OR Open/Close, which means at some point your desired set of actions will require you to press the button, move the stick one way, center the stick, let off the button, move the stick the other way. Folks who have this set-up say that with a little time it becomes second nature and they like having the ability to feather the 3rd function
Option 3 - A "true" 3rd function $$$
In this case you have 2 buttons on the loader control that operate a separate solenoid valve which controls the Open & Close function of the grapple independently of the loader valve.
The catch & the reason I put True in quotes, is that it will only be able to supply the fluid from system that is NOT already being used by the loader valve. What that means in English is that even though it's a separate valve / function it will most likely not operate in tandem with either the Lift/Lower or Dump/Curl functions in operation (unless you are feathering them very very lightly).
PRO - A slightly simpler control set to learn and the ability to come close to getting true 3rd function operation **
CON - These valves are simple On/Off valves so you have no ability to feather other than just making quick "blips" on the control button.
I've run our grapple like that for quite some time and honestly I haven't seen a single issue with not having the ability to feather, but I don't grapple eggs and glass either.
There are several great kits for all three options on the market from forums supporters like
Michigan Iron & Equipment and
EverythingAttachments, MtnViewRanch (Fit Rite Hydraulics -
fitritehydraulics.com) and
Kens Bolt On Hooks to name a few.
You also have the option to build your own (for each option). Several folks here (myself included) have done that. I have attached the write-up I did for our CK35 3rd Function if you're interested.
** Michigan Iron & Equipment has recently released a new 3rd function kit that is plumbed / ported in such a fashion as to allow true 3rd function operation. They offer both a simple Off/On like the other 3rd function solenoid version (but with true independent operation) or a Proportional Version that allows feathering like a Diverter set-up. miemachinerydivision
The PRO (obviously) is these allow true independent operation of the 3rd function regardless of what the loader valve is doing.
The CON is cost. As of right now it's $1195 for On/Of and $1495 for Proportional.
