BIGHAM BROTHERS, INC. BE A SAFE OPERATOR, THINK BEFORE OPERATING. READ ALL INSTRUCTIONS BEFORE ASSEMBLY OR OPERATION OF THE CULTIVATOR! Model 888 Cultivator on Rigid Tool Bar INTRODUCTION: The Model 888 Cultivator/Lister has two primary functions: cultivation of growing crops and pre-plant bedding operations. Independent parallel-linked gangs assure consistent operation over uneven ground.
BIGHAM BROTHERS, INC. The BIGHAM BROTHERS Model 888 Cultivator is equipped with an uneven number of parallel linkage tooling gangs—one for each crop seedbed plus one. Normal configuration includes a leading trash-cutting coulter with depth band or height adjustable tire, a center swivel coulter, sweeps or barring-off discs, and a rear chisel shank with bedding or cultivating tools.
BIGHAM BROTHERS, INC. Mount Gangs to Tool Bar Two types of gang mounting assemblies are available: the Rear Mount assembly and the Wrap-around assembly. Each is fastened by use of two u-bolts for each gang. See pictures 1-5. Position each clamp so the gang is centered between the crop rows. Note alignment cuff on rear mounted clamp assembly. If equipped with screw jack, fill the jack cavity with grease once each season through the grease zerk in picture three.
BIGHAM BROTHERS, INC. Set Operating Depth: Front Tire or Coulter Gang operating height is set by either an adjustable depth control tire or one of several front-mounted residue cutting coulters. Rigid and Swivel Coulters mount directly to the gang and do not adjust vertically. The Adjustable Coulter and Adjustable Tire allow vertical adjustment via the screw jack (picture 8). Using the adjustable coulter or tire allows working height of the gang independently of the other tooling.
BIGHAM BROTHERS, INC. Center Mounted Swivel Coulter Non-adjustable swivel coulter mounts to the frame behind an adjustable tire. Does not include depth band. See pictures 11-12. Picture 11 (806) 745-0384 705 E. Slaton Rd. Picture 12 P.O.
Tooling Bar Options BIGHAM BROTHERS, INC. Two tooling bars are available for mounting tools like barring off discs or cultivator sweeps. The Quick-Adjust tooling tube positions barring off discs with pin settings. No wrenches necessary for side-to-side or vertical disc adjustments. The 4x4 tooling tube mounts standard shanks and clamps for discs or cultivator sweeps. Each tube is held in place with a set screw on top of the gang tube (picture 13). See pictures 13-14.
BIGHAM BROTHERS, INC. Rear Shanks The cultivator gang mounts a chisel shank featuring Bigham Brothers’ No-Twist™ foot piece. Note the rear mounting tube that may be adjusted vertically with four flange bolts. Start by moving the The rigid shank mounts directly to the chisel shank mount tube at the rear of the gang. If you are mounting a 1x3” straight shank with a clamp, request the mounting tube, part number 689-244 without the chisel shank guides.
BIGHAM BROTHERS, INC. 1 2 Picture 18 3 Picture 19 Picture 20 9 5 4 17 1/4” +- 1/8” Picture 21 Picture 22 The Spring Loaded Chisel Clamp should be assembled when you receive it. However, you will need to partially disassemble it to mount it on the 4x4 tooling bar. When assembled, the chisel shank clevis obscures the bottom end of the u-bolt (#1) which secures the clamp to the 4x4” bar. To install the nut, you must first remove the pivot bolt (# 2). The nut will be left loose from the factory.
BIGHAM BROTHERS, INC. Warning! Position barring-off disc hubs as detailed below. Barring-Off Disc Hubs Mounted on Cultivator Gangs Description: (1.) Covering Disc Hubs MUST run in the correct direction or the spindle bolt will work loose, resulting in loss of disc and bearings. The spindle is fastened with either a left-handed or right-handed bolt. It MUST be installed on the proper side of the row to insure that the bolt stays tight during operation. (2.
BIGHAM BROTHERS, INC. Attaching Tractor to Model 888 Cultivator Tractors Without Quick Hitch: Choosing the proper tractor: 1. It is extremely important to utilize a tractor with sufficient horsepower and traction. Soil conditions and tooling (i.e. bedding tools vs. cultivator sweeps) will effect horsepower requirements, but allow 10-30 HP per row, i.e., 4 rows requires a 40-120 HP tractor. 2. The Model 888 Cultivator is equipped with rearextending gangs.
