I have Bolens 1050 that I repowered with a Wisconsin THD. I use this tractor for pulling at my local 4-H fair. At my last pull I won by pulling 5,300 pounds. at the end The clutch started to slip. A couple years back I replaced the clutch pads, so they are still good. Is there a way to put a bigger spring in it? Also
this is the tractor for reference point
