GP motorgrader Hydrolic Fluid Thermostat and heater to maintain the exact temperature for the hydrolic fluid to be always the same than when you calibrated your valves coils.

Example: When I'm fine grading with Trimble UTS 3D control on my 772GP, and the hydrolic temp is at 48 degres Celcius (the same temp than when I calibrated the valves) and in the same day when the sun replace the clouds... the hydrolic fluids just climbs to 54 degres celius and the valves coil are not able anymore to give the same precision than when it was at 48 celcius and the Motograter become unstable and out of tolerence until I re-calibrate the GP valve for the 2 blade cylinders.

When the temperature is more than 4 degres celcius defferent than the calibrated temperature. normally with The Trimble UTS , the Valves coils wroking well to keep the Grade between (5mm) or (1/8'') but when it's out of the temperature range, the GP Valves are not responding until it reach a 15-20 mm (3/4'') out of the desired grade. when the valves decide to move, it's too late!.

I have a other idea to corect that problem.... call me or send me an email

The response from the EH travel control is wrong. Travel dampening is high and acceleration is low. this makes it hard to stop at the edge of a trench, for example. Steering is very agressive and this makes the machine difficult to control on rough terrain.
Both, machine agression (rate at which machine accelerates) and control dampening needs to be tuned and adjustable by the operator. Also, the controls should be mounted to the seat armrests to minimize inadvertent movement.

One other complaint that I have is that you use a gear pump for the hydraulic system. The effect is that 1) response varies with load, 2) there is no linear correlation between lever position and hydraulic speed, 3) running an implement off the auxillary hydraulics often impairs boom and bucket control, and 4) the system wastes fuel and robs power by pushing oil through the relief valve. This is significant when running attachments such as a snowblower.

How about taking a look back at the 317 skid loader vs. the newer 318Ds: The holes under the foot paddles are gone! Now it takes about a half hour to clean and the whole cab gets dirty. And why did they change the engine oil filter from vertical to horizontal, with no room to put anything under it to catch oil coming out of the filter. A jelly jar will not even fit under it! The side panels on the engine compartment have made me very mad on several occasions on the 318D, the ones on the 317 are easy to put back on.
I think you should keep it simple and easy to clean and service.
Do still like the JD skid loaders, but really like the 317s simple design.
