Just picked up a new l3560hstc and 1860 brush hog. Was doing some cutting yesterday and hit a stump and it stalled the tractor. At first I didn't know what had happened. I was mowing at the reccomended 540 rpm range. I'm kinda new to the tractor scene but I thought for sure there was some type of safety clutch or shear bolt to prevent this from happening as it can't be good for the tractor.
The slip clutch on your mower is intended to reduce the possibility of tractor or mower damage when hard objects like stumps or rocks are hit. It is not intended to prevent stalling the tractor.
To function properly, the slip clutch must be adjusted to the HP of the tractor and the HP rating of the mower gearbox. Doing this properly is time consuming. I have NEVER known of ANY dealer that does this when selling equipment.
Additionally, slip clutches will sieze due to corrosion if not slipped periodically. If, as is almost certain, yours is adjusted too tightly, it will never slip and will sieze in short order. To prevent this, a slip clutch should be loosened and slipped at least once each season. Again, this is time consuming and very few owners do so.
There is much to be said for (proper) shear bolt protection aside from reduced cost.
