DOWN FORCE KIT INSTRUCTIONS

KIT #170810 DFK-50

(FOR MODEL 300 POST HOLE DIGGER)

ATTENTION! Tractor must have auxiliary hydraulic outlet

to operate this hydraulic down pressure kit.

If your tractor does not have this outlet, check with your tractor dealer.

INSTALLATION

1.Refer to the parts illustration and install the Down Force Kit parts as shown. The pin attaching the boom to the yoke is replaced by a 3/4 - 10 NC x 6” lg. hex head bolt and lock nut.

2.Use a good grade hydraulic thread sealant and install the hydraulic components. Do not use Teflon tape!

3.Install the hydraulic cylinder and boom clamp. The cylinder rod should be retracted and the boom clamp installed loosely so that it can slip on the boom. Raise the Post Hole Digger to its full up posi- tion. Now tighten the boom clamp bolts to 300 ft. lbs. torque. It may be necessary to retighten the clamp bolts after initial use to keep the clamp from slipping.

4.Connect the pressure hose (item #15) to one of the tractor remote outlets.

5.Connect the return hose (item # 16) directly to the tractor hydraulic reservoir fill opening. NOTE: DO

NOT CONNECT THE RETURN HOSE TO A REMOTE OUTLET. The remote outlet valve ports are blocked in the neutral position and will damage the hydraulic cylinder or other parts when the boom is raised.

OPERATION

Lower the Post Hole Digger in the usual manner and allow the auger to dig. As down force is needed, apply it carefully and in small amounts by using the control lever on the tractor remote outlet. It will be necessary to continue lowering the lift arms as the auger digs. Applying too much down force at one time can stall the auger and possibly cause the shear bolt on the post hole digger input shaft to shear. NOTE:

REPLACE THE SHEAR BOLT WITH A GRADE #2

(SOFT) BOLT ONLY. Using a (HARD) bolt can dam- age the auger, PTO driveline or gearbox and void the warranty.

The boom can be raised in the normal manner with- out relieving the down force cylinder pressure.

NOTE: DAMAGE CAN OCCUR IF HOSES ARE

NOT CONNECTED CORRECTLY. If the return hydraulic hose is connected to the other tractor remote outlet instead of directly to the tractor hydraulic reservoir, severe damage will possibly occur to the hydraulic cylinder and post hole digger when the boom is raised. Make sure hydraulic hoses are connected correctly.
