dEPTh REGULATOR LEvER
Tilling depth is controlled by the height of the depth regulator lever.
To adjust tilling depth. 
(SEE FIGURE 4)
1. Remove detent pin.
2. Raise the depth regulator lever to position tines at chosen tilling 
depth.
3. Align hole in depth regulator lever with hole in depth regulator
bracket and replace detent pin.
Depth Regulator Lever Down = Shallower tilling. Place the
detent pin in the top hole of the depth regulator lever for shallowest 
tilling.
Depth Regulator Lever Up = Deeper tilling. Place the detent 
pin in the bottom hole of the depth regulator lever for deepest 
tilling.
BELT TENSION AdjUSTMENT
Proper belt tension is critical to good performance. After 1/2 hour of 
operation, all cables may have to be adjusted due to initial stretch. 
Thereafter, check tension after every 2 hours of operation. 
To increase belt tension: (SEE FIGURE 5) 
1. Loosen upper jam nut. Turn nut up cable in 1/8” increments.
2. Tighten lower jam nut.
3. Check adjustment.
This procedure can be repeated until conduit adjustment bolts are 
fully adjusted. If no more adjustment can be made, belt may have to 
be replaced.
