MX5100 running hot when bush hogging

[Jimmy2980]

My 2013 mx5100 hst has always ran at the very top of the temperature gauge while bush hogging. I have taken it to the local dealer and they could not find any reason for it. I had the injectors inspected and repaired, and I thought that may make a difference, but it didn’t. Changed the hydraulic fluid. Had the radiator flushed and inspected, no problem was found. Changed the thermostat, no difference. Replaced the water pump and belt, no improvement. Even bought a new $48.92 radiator cap, but no improvement. No valves are sticking, pump is not whining. With it always running hot when bush hogging, there is no forgiveness when seeds and chaff buildup. I feel like it’s something simple that I am missing. Any thoughts?

Does it run hot doing anything else that doesn’t involve mowing?

What size/type of mower?

How close are you mowing and how thick is the grass?

tell us more details.

My MX5100 temperature gauge has always been 1/4 when warmed up and will creep towards 1/2 and 3/4 when the radiator is starting to get blocked.

Get an infrared temp gun and check it with that. Measure the upper and lower radiator hoses, engine block etc. Without actual numbers it’s all guessing.
