You do not have a problem. Air cooled small engines are designed to be run at full throttle in order to mow correctly and to cool the engine properly. Running it as less than full throttle will cause the engine to overwork and possibly overheat thus shortening it's life. It will also not cut properly as you have found. The engine has a governor that prevents you from running it too fast. Run the engine at full throttle at all times when you are mowing which is the optimum speed for proper operation. You may think you are helping your engine by running it slower but in reality you are harming the engine. It is air cooled, not water cooled, and needs the revolutions in order to cool itself properly. Also use 100% synthetic oil in this air cooled engine for more protection. Change your oil/filter once a year or every 50 hours.

Blade speed equals engine speed. Check your carburetor and fuel pipe
Make sure you sharpen the blade with - this is more important for a good cut.

Need to know how to change transmission fluid on cub cadet lt 1045 riding mower


Cub Cadet has five models in their new Series 1000 lawn tractors, all powered by Kohler engines. Cub Cadet models -- as several other lawn equipment brands -- are manufactured by MTD Products.

The Cub Cadet LT 1045 has a 20-hp Kohler single-cylinder engine, with an aluminum block and cast-iron sleeve for longer life. It has a full-pressure lubrication system with spin-on oil filter for easier maintenance. This engine is not as powerful or as long lasting as the Kohler V-Twin OHV, which is available in other models in the line, but the LT 1045's engine is still solid enough to provide years of mowing.

The hydrostatic (automatic) transmission is a good match with the engine and provides sufficient grip to cut grass on moderate inclines. Power is transferred from the engine to the transmission by a heavy-duty Kevlar belt rather than a more expensive shaft drive. A Kevlar belt also drives the three cutting blades.

The mowing deck cuts a swath of grass 46 inches wide at one pass, and is removable for service and cleaning. Four anti-scalping wheels help keep the deck from scalping grass on uneven ground. The cutting height is manually adjusted from 1-1/2 to 4 inches. The turning radius is 18 inches, which standard for lawn tractors. This model is intended for use on 1- to 2-acre lawns without many turns or small obstacles.

Turn off mower blades the electric clutch spins and the two green


There should be a metal "anchor" that bolts to the chassis or engine. It has a rod that sticks downward, fitting into a notch in the clutch to keep it from turning. It must be missing or broken, or maybe the clutch is the wrong model, and that's why the clutch itself spins and rips out the wires. Good luck! Please rate if you found this helpful, thanks!

Once engaged and start mowing, you can mow for about 20 feet or more and then it just slows down and the engine wants to die, but stop pulling immediately and the engine catches up and goes back to full...


This actually happened to a friend of mine! I saw it! Mow about 20 feet, and had to stop, then 20 feet...well, you get the picture. It was his air filter! Stopped up pretty good. We blew it out and it worked fine.
I really hope this helps. --W/D--

Craftsman DYT 4000, 24 hp 48" deck. While I was mowing, the blades stopped turning, started again, and then stopped. I shut down, all looked OK, tried to start and nothing. No click, nothing. Any ideas?


there is a fuse in engine compartment that might have blown causing the engine or blades not to start but what probably happened was something got caught in the blades check under the deck & see if there is & also try spinning blades by hand & see what happens

Mowing


I did the same thing. I replace the belt that turns the blades. The pressure of the impact had stretched the belt and was slipping on the pully that engages the blades. Try that first and check the other belts for tension, wear and condition....Also make sure all springs are attached, not stretched, and in good shape...Hope this is helpful....Joe
