INITIAL MOUNTING INSTRUCTIONS
Note: Prior to Serial Number ---1095, begin with
step 1. Starting with Serial Number ---1095, the
7/16 x 2-1/2” bolts are standard on the tractor, skip
to step 2.
1. Raise up the tractor and remove the existing
wheel. Drive out the five stud bolts from the
hub (See C-13, Ref 2) and replace with
provided stud bolts (7/16” X 2-1/2”) from the kit.
2. Remount wheel using the original lug nuts.
3. Install inner dual mount (See C-13, Ref 6)
(Figure 31A) with the standard 7/16” SAE nuts
and tighten.
4. Mount dual wheel to the dual extension (See
C-13, Ref 8) (Figure 32A) with lugs nuts from
the kit.
Note: tighten all nuts to approximately 55 ft. Lbs.
5. Make certain the wheel extension is assembled
per the drawing. Draw bolt (See C-13, Ref 10)
with flat washer is inserted through the
extension and threaded into the draw cone
(See C-13, Ref 7).
Note: the pin on the draw cone must be turned
toward the draw bolt head.
DUAL WHEEL MOUNTING/OPERATION
KTA (LATE) STYLE
Dual wheels are an available option for the VENTRAC 4100. (Heavy Axles are required.
All 4100’s serial #’s ---1091 and above come standard with Heavy axles. Serial #’s
---1090 and below must have optional Heavy axle kit 70.0096.) They are useful for
increasing stability on slopes and to reduce soil compaction. Once the dual mounting
hubs have been installed in each wheel, the dual wheels can be mounted and
dismounted quickly by the center draw bolt. Dual wheels can be used on any or all four
wheels. Keeping the center draw bolt tight, the inflation pressure of the outside
mounted tire to a max of 4 psi, and operating the Ventrac gently are all important for
successful, safe, and continuous performance of the dual wheels.
Dual wheels are recommended for sandy soils or where a broad distribution of tractor
weight is desired, including operating sideways on slopes greater than 20 degrees.
Dual wheels are only one of numerous considerations for safety on slopes. Speed,
terrain, irregularities, and even the potential for equipment stoppage are serious factors
to consider for safe operation of the tractor.
