Speed of tractor slows when I run for more than 10 minutes. It will not climb a small incline after it gets hot. I can let it cool for a half hour, then it runs fine untill it gets hot ,and eventuall will not moove at all on an incline. It will still run fine on level ground.

it will run slow for 40 mins at a slow speed, after 15 mins of running fast, the batteries get too hot

Does the motor rpms slow down or the mower speed?

Hi, Try replacing the thermostat. It's a valve that opens when engine gets hot. When it doen't work properly engine temp will rise. Good luck.

First question is what constitutes "overheating".
Since the car has been parked for years, the thermostat could be sticking closed.
The cooling system could have air pockets and need to be bled.
The water pump may be corroded inside and not pumping enough volume.
If the gauge goes above half way, the fans should start up. But half way should be more or less normal, not hot yet.
I would look at flow problems first, beginning with removing the thermostat and driving it without one for a few days. Also check and see if there is a process to bleed the cooling system of air.

Add incline. Instead of keeping the treadmill on a flat surface, maintain an incline as you walk, jog or run. This will serve to replicate the wind resistance and terrain variation that you encounter when you run outdoors. Keep an incline of at least 1.5 percent on your treadmill throughout your workout.

2 Increase your speed. If you run at the same speed every time you workout, your body will not be challenged and you may reach a fitness plateau. Up your speed by a quarter-mile per hour every few weeks.

3 Vary your workout time. In order to challenge your body in different ways, variety is key. If you run for half an hour three times a week, opt for a one-hour run for your fourth workout. This will help to condition your body for endurance training, resulting in more calories burned.

4 Use intervals. Interval training can dramatically increase your calorie burn in an average workout. Instead of running at a steady pace for your entire workout, mix in sprints. Jog at a steady pace for two minutes, and then increase your speed to a full sprint for 30 seconds. Return to the steady pace to recover. Your heart rate will rise on your intense sprint intervals and stabilize on your longer recovery periods.

5 Incorporate incline into your interval training. You can use incline in the same manner that you would speed to interval train. Walk or jog at a 5 percent incline for two minutes. Increase the incline to 10 percent for two minutes and then to the 15 percent maximum for one minute. Decrease the incline back to 10 percent for two minutes and finally back to 5 percent for two minutes. Repeat this same pyramid interval a few times.

6 Wear a heart rate monitor. This will monitor how hard you are actually working as well as how many calories you burn in each workout. You can then adjust your speed and incline accordingly to maximize your calorie burn.

7 Drink plenty of water before, during and after your treadmill workout. If you are dehydrated, you won't perform as well as you can. You'll work harder and burn more calories if you're hydrated

Sounds like a weak fuel pump.You will need to put an inline fuel gauge to check if you have good fuel pressure, if it's over 10 lbs, you have another problem, like a clogged fuel filter. You can find an inline fuel gauge at Kragen or Pep Boys.

Hi, the hydrostatic drive is most likely over heating. Remove the battery and battery carrier, from here you can clean all grass and debris from the hydro cooling fins and fan. Hope this helps, regards Phil.

It could easily be an electrical issue, or not. Get a spark tester (hooks up to the spark plug). Pep boys, Autozone, and Napa all sell them for less than $10. Check for spark when the mower has quit. If no spark, most likely need to replace the ignition module. Also check the flywheel key, if it is has been sheared or even knicked, the engine will run hot.
If you still have spark when engine has failed, check the vent on the gas cap. A clogged vent will cause a vacuum to form in the tank and stall the engine.
Good luck!

Hi
Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.
