ADDITIONAL TRACTOR FRONT	BAL -
LAST MAY BE NEEDED FOR STABLE
OPERATION AND TRANSPORT OF	THE

TILLE R. SEE T RACTOR O PERATO R’S MANUAL FOR RECOMMENDEDWEIGHTS.

NOTE

The RTN series tiller ma y be offset to either side if so desired. I nstructions for offs etting are giv en in paragraph 2-3.

A. Attach tiller to tra ctor 3-point hitch pe r tractor operator’s man ual. Do n ot attach driveline at this time.

NOTE

Due to the many variations in tractor/implement hitch points a nd c orresponding differences in di stances between tractor PTO shafts and implement input

shaft s, drivelines m ay need t	o be shortened as
described in the following steps:
B. Raise and lower tiller to	determine po sition

with shortest distance between the tractor PTO shaft and gearbox input shaft. Shut down tractor, leaving tiller in position of shortest distance. Securely block tiller in position.

C. Pull driveline apart. Attach outer (female) sec- tion to tractor PTO sha ft. Pull on drive line section to be sure that yoke locks into place.

D. Hold dr iveline sec tions pa rallel to eac h other to determine if it is too long. Each section should end

approximately 3 inches (76mm ) s hort of reaching universal joint shield on opposite section. If t oo long, measure 3 inche s back f rom universal joint shield and mark on opposi te section. (Figure 2-1 ). Do this for both sections.

Figure 2-1

E. Raise and lower t iller to d etermine position with greatest distance between PTO shaft and gear- box input sh aft. Shut down tractor le aving til ler in position of greatest distance. Securely block tiller in position.

F. Hold driveline sections parallel to each ot her and check for minim um 6 inc hes (15cm) overlap. (Figure 2-2) If driveline has been m arked for cutting, overlap wil l be the distanc e be tween two marks. If driveline has less than minimum overlap, do not use. Contact authorized Bush Hog dealer.
