KMech - 1/1/2014 17:15 Does anyone know a good webpage that just lists and defines what all these are? pilots, eh, iso, h=pattern, etc? All I know is the last bobcat Dad got had a switch, and you can go either way you want. I don't know which is called what, though.
I wish there was a universal guide at every dealer to avoid confusion.
Pilot Control: A low pressure pilot hydraulic system is operated by servos under the joysticks. The low pressure oil operates the high pressure valves versus say a cable or lever. Very common on all kinds of construction equipment in the last 10-20 years, starting to get phased out by EH but still popular. The hoses run right up to the joystick. ISO is the most common pattern with this control but they could be ordered or configured later with the H pattern as well by redoing the hoses. I supposed you could custom make it a different way if you wanted but those are the two patterns they came with. Most will set them up at the factory with the different pattern much cheaper than doing it later at the dealer. Emissions controls and more sophisticated loader functions are phasing these out in favor of full EH controls.
EH Control: Electro-Hydraulic, essentially fly by wire. The joysticks are electronic and electronics operate the valves instead of a pilot system, cable or lever. Same thing that is used to run most tractors auxillary hydraulics these days, lots of variables play into the response and control you have with them though due to relying on a computer.
ISO Pattern: The international standard pattern for Skid Steer and CTL controls. Left stick drives (point and go), right stick boom/bucket (same as loader control) Like anything else ISO, it means everybody sat down eventually played nice and said this is the control pattern that will be the international standard. Just like with quick couplers, ISO plugs on tractors etc. That doesn't mean they necessarily have to switch it to, but almost all of them offer it. At least in the US all of the offer it, theres some Australian models and maybe some other brands overseas that do not offer it. I don't know of any SSL with this pattern that does not use either Pilot controls or EH controls which is why the generalization of Pilot with ISO happened and caused a lot of confusion. Cat has uses Pilot controls with ISO since day 1 which really isn't that long ago (late 90s). Many used to call them Cat controls until other brands started offering Pilot controls, they mostly all came with them setup for the ISO pattern so the names kind of got associated with each other. Kind of like some people still call any Skid Steer a Bobcat. The way it was explained to me was that this pattern was decided on because it was easiest for new people to understand ( those who were not predisposed to any pattern) and part of the reason it was easy to understand is due to its similarity with other construction equipment patterns.
H Pattern: Otherwise commonly known as Case pattern, and some Bobcat people call it a Bobcat pattern even though traditionally Bobcats pattern is Hand/Foot and they were the pioneers of it on the first skid steers. The H pattern drives the same as hand/foot controls but the left handle pivots in and out to lower and raise the boom, the right handle pivots in and out for curl/dump. Traditionally these use mechanical drive levers with either cable or servo operated controls for the loader functions.
T Bar: I don't know the new Gehls/Mustangs all that well. I don't know how the new two lever T bars work, I'd have to catch up on them. The old ones could cause some confusion with Hand/Foot controls as they only used one stick right between your legs. Push it forward for forward, pull back for reverse, twist to the left for left, twist to the right for right, loader functions were normal foot controls on the floor.
Hand/Foot: This is the traditional control many Bobcat, Deere and NH owners are used to. Two drive sticks on each side of you for driving each side of the machine, and two pedals on the floor one for the boom and one for the bucket. All mechanical.
Pattern Changer: There are various types of these, but when referring to all NEW SSL/CTL's in general a pattern changer is an optional or standard piece of equipment that comes with EH controls. it allows you to switch between ISO and H pattern to suit more operators preferences. Many H pattern operators find it akward though because the sticks are not the big long mechanical drive sticks they are used to. Some are used to H pattern with Pilots but not always. The Joysticks are much different to operate due to the shorter throw.
Bobcat ACS: This is the type of control that your dad probably has, its not that expensive and allows you to switch between H pattern controls and Hand/Foot style controls. Its a feature that pays for itself in resale and versatility although they do have some high wear parts in the system.
Bobcat SJC: This is Bobcats terminology for their EH controls. When I priced an S205 in 2011 they wanted an extra $2,400 for EH controls and strongly suggested against it due to Bobcat owners in the area not wanting them, meaning less resale value. IIRC New Holland was also charging around $1,800 at the time for EH controls in the L220 I priced.
So what does the future hold? Who knows, but the trend is more electronics especially on the machines over 75hp. Emissions is part of it and the other big part is the added features on new machines. Things like dual leveling, work tool positioners, electronic throttles, decel pedals, hydraulic snubbing, and many other features that are being carried over from larger machines like wheel loaders and down into the SSLs and CTLs to make them more productive. Its easier to incorporate most of these features with EH controls. EH controls also allow quiet and sealed cabs because there is no noisy mechanical linkage to come through the floor to worry about. C and D series Cat's have the floor sealed with the entire cab, it never splits. The D series even seals the HVAC to the bottom of the cab so there is no more joint there. This allowed for twice as much pressurization in their cabs and even more noise reduction. They were already really quiet and now they are quiet enough to use bluetooth. All things you may not need, but evidently the market pushed it there and I know more people that like the new features than those who do not.
The future will go towards more EH controls, but it will be a long long long time before we see mechanical controls go away. They will disappear on the big machines first, then the smaller ones but companies like Bobcat NH, and Deere have too many customers with H/F controls to leave them hanging. They would all have to jump ship at the same time leaving all of the customers with no place to turn. The EH controls improve all the time and while I doubt they will ever get much feedback into them, I hope they can refine the precision and speed some more. User customizability is nice with the EH controls. You can set your preferences and every time you log into the machine they will be there. This is the way the D series Cat's are with the optional display and Bobcat is the same way with their display IIRC. CNH offers adjustability but I am not sure if it is saved by PIN code or just stays where it was left off at by the last operator.

Bobcat Offers Selectable Joystick Controls
Hawk Steel, Kennendale, Texas, will be installing an extensive metals separation system at its Texas auto shredding facility. Pete Bausone, owner of Hawk Steel, says the new separation system will include two eddy current separators.
The company, which already has one eddy current separator inline with its auto shredder, says it hopes that by adding additional sorting equipment offline, it will be able to extract more aluminum, copper and other metals from shredder fluff.
Hawk Steel’s auto shredder, located on 18 acres, runs one 12-hour shift per day.
American Pulverizer, St. Louis, and Hustler Conveyor, O’Fallon, Mo., are supplying the equipment, which, Bausone says, should be installed by this fall. The equipment to be used at the facility includes a Hustler tumbleback metering conveyor; an American Pulverizer trommel screen designed for three size splits of materials that will be fed to the fines separator; and a standard eddy current, with overs (5-inches-plus in size) going to a picking conveyor.
This system also incorporates an S&S (SiCon Technology) induction coil machine for further removal of nonferrous materials.
The platforms are designed for access to all of the equipment and offer multiple picking areas for more efficiency.
The system is designed for further recovery of materials, yielding a higher percentage of nonferrous recovery per ton of ferrous scrap shredded.
Bausone says that because markets are starting to improve, installing the system should help the company out. “It puts us in a much better position.”
Selectable joystick control now available from Bobcat
The new Selectable Joystick Control (SJC) option for the Bobcat S100 skid-steer loader offers increased functionality, including a two-speed range that is said to have a faster maximum speed than any other loader in this class.
Previously only available for larger Bobcat loaders, the two-speed ranges of the SJC option allow for faster travel and thereby faster cycle times between dig and dump sites as well as from one job site to another. Compared to the maximum speed of 10.3km/h in the single-speed system, the two-speed maximum is 35% higher at 14km/h. In addition, a speed-management system (SMS) allows the operator to pre-set the speed required for working with specific attachments such as tillers and trenchers.
Steering drift compensation can be used to maintain a desired travel path in both directions. This feature can be used to compensate for normal variations such as tyre inflation pressure and tyre wear when driving on uneven terrain, such as crowned road surfaces, and when using side shift attachments such as trenchers and planers.
The SJC system on the S100 gives the operator a choice between hand-operated or foot-operated control of the engine speed. To suit different needs and preferences, there are also three settings that change how responsive the loader’s drive and steering systems are when the operator moves the joysticks. The SJC system also gives a choice between ‘ISO’ and conventional ‘H’ skid-steer hand-control patterns on the same joysticks, simply by pushing a rocker switch in the cab.
The SJC system provides easy front auxiliary hydraulics operation with a choice between variable flow, allowing for slow-to-fast movement of auxiliary hydraulic functions, and continuous flow, which allows for a constant flow of auxiliary hydraulic oil to an attachment. The SJC system also has a float feature for levelling the ground surface.
With an operating weight complete with bucket of just 1,800kg, the S100 skid-steer loader offers a rated operating capacity of 453kg and a tipping load of 907kg. Compact dimensions - a height of 1,878mm, length without attachment of 2,262mm and width over the tyres of 1,182mm – allow the S100 to manoeuvre efficiently in confined spaces.
