My tractor really isn't for competitive pulling, but has belt slippage issues when I pull heavy loads around the yard. Like wagons full of rock or my 8500# 2.6 Dodge diesel sled puller when it dislocates parts on the track.
Anyhow the lister petter's crankshaft is slightly ahead and up from the original gas engine location so it seems the rear belt just isn't tight enough to hold the low rpm torque of the diesel in higher gears (3rd up) towing heavy loads. It will climb an approximate 40 degree grade in 4th low unloaded. I have messed around with the varidrive several times, but it seems I can only just make it work good enough. I have thought about adjusting the width of the rear pulley. I have never got the front end to lift under load, in lower gears it will spin the 23x10.50x12 carlisle ag tires at idle if it can't get enough bite.
I had read about modifying the rear belt tensioner for pulling, I am curious what my options are?
