Page 77: Step Cutting
QUALITY OF CUT 12 12.3 STEP CUTTING____________________________________________________________ Step cutting occurs when grass is cut higher on one side of a cutting unit than the other side. Step cutting can occur when one cutting unit is higher than another cutting unit. The wear of mechanical parts or an incorrect roller adjustment can cause step cutting. -
Page 78: Scalping

Need help?
Do you have a question about the R311T-T4F and is the answer not in the manual?
Questions and answers
The check engine light comes on and the machine will only run about half throttle and if you stop it and start it again it won’t be on. Was wondering where you can plug in and run a computer check on the check engine light and if a service garage could check it or would it have to be a Jacobsen dealer.
You can plug in a computer to check the check engine light on a Jacobsen R311T-T4F using the Kubota Engine Controller (ECU) diagnostic connector, which is a four-pin CAN bus connector located near the engine controller on the right side of the cowling.
A service garage may be able to perform this check if they have the correct diagnostic tools, but for factory support with mower controller issues, it is recommended to contact an authorized Jacobsen Dealer.
