When I was younger I absolutely HATED changing gear on the tractor - it was a matter of dropping the revs which caused a dive, then a clunk finding the gear, then a jolt as the gear took hold and the revs came back up
I never felt in control of that old beast
Changing gears while driving? Are you sure you where supposed to? Many old tractors are without synced drives, so you are supposed to select gear before you start driving. Of course you can change when driving, but then you have to match revs to not get the drop betwen
Ha ha, that's such a wonderful description, that's exactly how it feels!
