185 lo boy deck question

Postby JohnnyJay » Sun May 14, 2017 8:07 am

Did I have to remove any implement off the real cylinder to get the deck mower to go down? Also where do I check for hydraulic fluid level? Thank ahead, John

No, answer to first question. Hydraulic fluid level is checked by opening the plug on plate on the rear of the differential.

Suggest down loading the Operator's Manual, top of page, quick links. The Operator's Manual will answer most of your questions.

There are several different hydraulic configurations for the Numbered Cub Low-boys. Again, the Operator's Manual explains how to utilize each system. One system utilizes a screw on the left mid point of the tractor to lock out the center hydraulic cylinder and a locking bar to hold up the 3-point. Another system utilized a diverter valve, located on the panel between the operator's calves to control the hydraulic cylinders.
I have an excuse. CRS.

have to remove any implement off the real (Rear???) cylinder to get the deck mower to go down

If you have a hydraulic diverter valve (knob on the tunnel below key) then each cylinder can be used independently. Raise 3-point hitch, switch diverter valve to lower position, then operate mower deck.

Without the hydraulic diverter valve, the two cylinders are pressurized together. The lightest weight lifts first, then the heavier weight implement lifts. The 3-point hitch can be locked out using a lockout bar (immobilizes the 3-point hitch), but this is a pretty inconvenient tool.

Before I added the diverter valve, I kept a trailer mover on the 3-point hitch that added enough weight to the 3-point that it made the mower deck lift first. That way I didn't have to wait for the 3-point to lift before the mower deck lifted. Finally got tired of not having my 3-point always available, so I added the diverter valve. Here's a knockoff version of the valve. Some brackets are needed.
