New to Bobcat 235

Bigasspilot · May 6, 2011

I am the proud owner of a new CT 235. This tractor is great! No pictures yet. After reading through the operating manual a few times I have two questions I wonder if anyone can share some insight.
1. Does the hour meter clock time relative to the rpm that the engine is running, similar to how an airplane clocks tach time? Or is it simply chronological time the engine is running regardless of rpm.
2. Does anyone have a reference/link/drawing of the hydraulic circuit of the tractor? I would like to understand the hydraulic circuits better.

I discovered this forum a few months before purchasing my Bobcat while researching which tractor to buy and am amazed at the wealth of knowledge the member possess and are willing to share.
Thanks

Congratulations on your new tractor.

Engine clock runs at same time regardless of RPM.

I don't have the drawing but can give a brief summary:
There 2 hydraulic gear pumps attached to the fuel injection pump. The front pump flows about 4.25 GPM to the steering circuit, through the oil cooler, then back to the hydrostatic filter HST pump. The rear pump flows 8 GPM to the loader control valve, then back to 3 point, and rear remotes if you have them, then though the hydraulic filter under platform and back to transmission (reservoir).

I believe the answer to the first question is that it clocks time that the switch is on. I do not believe (but I am not certain) the engine does not even need to be running. The answer to the second question is yes.

Clock won't start until you start the engine, but if you kill the engine clock will continue to run until key is turned off.

SSdoxie,
Thanks for the info. Are the two circuits completely separate or do they come together at some point? I hope my question is not too vague.ni wondered why there are two hydraulic filters.
I appreciate your help.

The rear differential is the reservoir for the hydraulics/hydrostatic systems. There is 1 suction tube line from the reservoir to the hydraulic pump(s). Share the reservoir and suction line. The hydraulic pump is one unit with 2 sets of gear pumps inside.

One filter is only for the hst transmission and the other filter is for all the other hydraulics (steering, loader control, 3pt, remotes). Apparently they want a dedicated filter for the tranny.
